good morning good evening good afternoon depending on where you're joining us um welcome to immersed my name is brian anthony and i'll just get us kicking off this afternoon with our new seminar series immersed is a seminar series designed to celebrate and enhance and enjoy how immersive technologies and new modalities for manipulating and understanding data are shaping innovations in science in engineering and art these immersed events will be a mixture of lectures and demonstrations and tutori
als we hope to offer a deep dive into the capabilities and set of capabilities that are available at mit that are available because of the innovations in ar and vr and the innovations in gpu technology in the innovations in thinking of how to intersect designed art and engineering and science to explore biology human health and diverse fields of engineering and science immersed is sponsored by the mit nano immersion lab we provide tools spaces people resources to connect the physical to the digi
tal and bring together researchers in these diverse domains so immersed builds in this foundation that immersive technology and new modalities for manipulating and understanding data are shaping all these interesting innovations across science engineering and art this first session today we would like to be coming to you from the immersion lab so we are virtually a quick tour of the immersion lab uh the immersion lab sits inside of mit nano and my my background is the mit no facility like all of
mit nano the immersion lab is open to the mit community and to outside users it is a heavily instrumented reconfigurable two-story space a black box theater plus compute that allows us to use the human as an as a a specimen in the instrument that is the immersion lab the immersion lab will facilitate immersed means being able to look at new ways of teaching and learning using the language of gaming and teaching and learning open spaces for classes and presentations hosting classes in virtual re
ality offering both educational and learning opportunities through both internships and undergraduate research projects through covid through this unique world that we've been living in we've also made the resources that are available inside of the room available to the rooms of our students into into the rooms of our researchers looking at both developing novel ways of exploring molecules that are only visualizable at the nanoscale or learning how to interact and measure physiological response
as people are immersed in virtual environments and what does that mean in terms of designing new games and new ways of interacting in new ways of learning one of the tools one of the many sets of types of tools that are celebrated by immersed that are available in the immersion lab our collection of tools for photogrammetry in this case a an instrument that has over 120 cameras that are a reconfigurable on reconfigurable stands that allow us to capture humans that allow us to capture physical ar
tifact both a three-dimensional representation that can be then animated and articulated the geometry but also the the the skinning the coloring the texture so it gives us the ability to take a physical artifact and get it into the digital world photogrammetry at the space scale so cameras such as this matterport camera that you may be familiar with if you've ever either rented or purchased an apartment online in the in the modern era where you can take a camera now very similar to what google m
aps does or google street view when you take a camera out into the world take cameras into the spaces and capture in this case the infinite corridor so that you can physically interact virtually interact with these physical spaces so photogrammetry is one set of tools that we celebrate and use motion capture we'll hear a lot today about motion capture and dance and biomechanics but these the space this reconfigurable space that is the immersion lab instrumented with cameras that allow us to trac
k markers and understand how people and artifacts are moving around the immersion lab is an integrated instrument for humans bringing together sensors of of optical sorts of of radar sorts of 360 cameras motion capture wireless physiological monitoring that really allows us to put the specimen of the human into the space understand how they move and interact and their signals of response on top of all these things we have an infrastructure for compute for data visualization for acquisition inter
action and interpretation of the data that we're acquiring the tools and capabilities of the immersion lab that are celebrated by this immersed series graphical form and available on our web page everything from immersive teaching exploring interacting with complex data sets whether it be through ar and vr wall mounted displays creating immersive content digital twins digital models of both human and physical artifact motion capture machine learning physiological studies art and music melding th
e physical in the digital uh in text form if i were to summarize the tools and capabilities of the immersion lab tools that are available to you if you're if you're listening to this if you're watching this these are available to you virtual reality motion capture media content creation photogrammetry and computation our mission is to help you do the phenomenal things that you want to do to propel research and education to bring together these these array of different technologies and creative w
ays in a single environment facilitate teaching facilitate interdisciplinary cross-pollination between art science and technology and bridging the domains of hardware innovation and software innovation and fueling the experimentation research that that you want to do both through the resources and the opportunities that we have for funding the immersion lab immersed means being immersed in things immersed in data so whether your interest is being immersed in sport in motion or being immersed in
sound or being immersed in data i want to welcome you to the immerse series here we go getting our oranges immersed in in in water so immersed a a monthly celebration of of all the the technologies that were the users of the technologies that we're celebrating today um so i want to just sort of um you know give you that as a little bit of a background and overview of of the immersion lab which is hosting this event and series of events uh and with that i'll turn it over to um my colleagues uh pr
anith samantha and ben will be sharing little vignettes about some of the the first uses of of what we've done in the immersion lab and i look forward to your participation in questions so uh i'll take it away thank you brian one of the latest things to come out of the immersion lab are two educational courses that we ran over independent activities period this past january today we're going to talk about these two courses i'm going to talk about biomechanics in everyday life this is the course
that i uh led and later sam farrell is going to talk about creating editing and distributing 360 photography so let me tell you a little bit about the course and give you a taste of what the students experienced so in this course students learned how motion capture photogrammetry and emg can be applied to understand more deeply everyday activities like breathing and walking so first i'll tell you what students liked about the course and then i'll try to give you a taste of it so the from our fee
dback so this course ran over five sessions and the according to the students they were able to participate in the course through this interactive app which i'll introduce you to in just a second and they learn to challenge their intuitions and we'll we'll do we learn to challenge one of our intuitions today and then they enjoyed live demonstrations and a combination of experience based on presentation based learning what i mean by experience based on presentation based learning is for example w
e had a yoga teacher come over and lead a 20-minute yoga session after that the students uh got to hear about the analysis performed using the tools in the immersion lab i'll show an example of that in a second but if you have a secondary device such as a phone or an ipad please open a browser window and go to slido.com and go to event number c442 now when you join you can upload this you can all ask questions upward questions people have asked so i'll know once you have joined so once again it'
s slido.com excellent we have our first participant give just a minute for people to join slido.com event number c442 i wish i could provide coffee virtually we'll get to the q a session in the end so thank you for starting to ask your questions excellent so we have some participants thank you for volunteering uh now uh here's a sneak peek of what uh i okay so let me explain when you just if if you're in your living room just stand up and try to jump around as you jump uh your muscles are going
to change the length so for example if you move your bicep it's going to get longer or shorter and so on so on average when our muscles longest during jumping what does your intuition say is that the highest point of jump when i'm in the air is it the lowest point of jump is it just when i'm about to take off the moment i'm going to take off on the floor or just when i landed on the floor what do you think when do you think on if you take the length of all the muscles and average them when do yo
u think they're going to be the longest i'll give you a second to answer okay let's see what you're saying the moment before taking off from the floor excellent let's see what students said in the course the students most of the students said as the highest point of the jump but the correct answer turns out to be this somebody got it they're very happy good job um okay so this is part of testing whether your intuitions are correct or not but then how do you tune your intuitions one thing we can
do is take a closer look using motion capture you can measure the length of muscles as i'm jumping rope this doesn't tell you very much i'll show you tell you much about muscle end but gives you an idea of how the experiment was conducted how the observation was made okay here is the length so let me explain there's a graph here so i'm jumping up and down the blue line indicates the position of my toe so when the blue line goes up it means my toe is in the air and this is the moment that i lande
d on the floor this is the moment i'm taking off from the floor right so lowest point of the jump is probably somewhere close to that so what happens here is once i touch the floor my eye muscles start getting longer so in this case it is my arm muscles so these specific muscles on the left right so we you can repeat this for many different muscle groups and you'll find something very similar the question is how can we retune our intuitions so in this case we did it using a toy model if you can
see my live video so here's a toy that many children use to play with so it has a bunch of rubber bands and some wooden sticks and then it it is pliable much like our bones and muscles and there are important differences so i put infrared reflective markers on the corner so i can track the length of these elastic bands so this is what happens when i drop it on the floor it was too fast to see i'm going to slow it down so it's getting to the floor once it touches the floor it's going to get squis
hed even though it's getting squished the length of the elastic bands increase because the body is absorbing the energy and then so that's the lowest point of your jump and then you retrieve that and then by the time you take off from the floor your muscles are actually the shortest right so here's an example of testing your intuitions and refining them and students learn to apply this to everyday activities right so perhaps observing things that are not very obvious to see unless you have a lot
of experience and intuition so here is me tracking my lat during yoga and then i'm going to stay in one pose and i'm just going to breathe so as i breathe you see that my back is responding maybe it's not obvious from the video but it's just a centimeter of change right so then you can take a closer look from a different angle and you can see that during the inhale during the inhale i tend to increa expand even in my back so i'm expanding overall so the students use this to deepen their intuiti
ons about how breathing relates to yoga uh i am running out of time so i want i'll show you one more video so the students also learned how to develop their awareness using tai chi and we used biofeedback demonstrations so what i'm recording are from the sensors that are on my arms over here and they show acceleration or when my in this case i'm looking for when my muscles end up tremoring maybe you spotted it maybe you didn't but it happened right there and you can see the tremor very clearly r
ight so i my shoulder gets a little unstable when my hand goes into this position and my shoulder when my arm goes into that position so i was i happened to document where i had the sensors i had my shoulder in the same position and i saw the same pattern so the students learned to in this course students learn to develop an appreciation for deepening their intuitions and awareness and understanding and how these tools can help in that regard if you're interested in the course itself then the vi
deo recordings are available online and just send us an email at to immersion mit.edu and i can send you a link to the videos now i'm going to turn it over to sam hi everyone my name is samantha farrell and um i am the assistant to the director of mit nano vladimir bolovich and i'm also a vr ar science sci-fi enthusiast so um in my case working at mit nano generally but specifically in the immersion lab is quite a thrilling and exciting place to be um and i'm thrilled that i have a chance to hav
e a little impact in trying to help with getting some of the programming going um i'm gonna give a little overview about a very exciting and successful class that we hosted over uh i over the iap period that was called creating editing and distributing 360 photography and uh videography um so i got involved in the emergent lab when we were starting to have um conversations about our potential users how do we make this a welcoming space how do we build a diverse and interdisciplinary community of
users and if i have learned anything during my time at mit i know that the magic of mit really happens when you get folks from all disciplines across campus bumping into each other um bouncing ideas off of one another and as vladimir has coined the term to me it's that human friction um that sort of leads to this incredible innovation and imagination that mit is known for and i think that the immersion lab has the potential to be such a place of intersection where storytelling meets big data me
ets art and performance meets technology and ways of communicating research um so it's just a really it's a really exciting um a space that i that i hope that we're just going to see keep growing and growing and evolving um so i took myself as an example of a person who would like to um a person who would like to use the room but perhaps is not a scientist i'm not a scientist i'm an administrative assistant um but i'm also a musician uh but i know that research starts with people asking question
s how does this work how is this molecule put together what is this you know how do things operate on the nano scale so my question was how do i make a weird uh music video in 360. that was my jumping off point um because i'm interested in immersive experiences and sound um so uh yeah so if you're not a computer programmer if you're not uh you know doing biomechanical research if you don't know how to use the lens cloud i don't know how to use any of those things but i'm like this is really this
is really an awesome room and i love the idea of vr and ar how do i how do i get involved here um so then let me just go here we enter russ gantt um he is the director of the harvard visualization lab and he's a leading expert on virtual reality uh technology and just an amazing all-around artist and entrepreneur and um i had the good fortune of getting to go get a tour of the lab space at harvard with vladimir and russ made the mistake of giving me his cell phone number and his email and i sta
rted i started pestering him with questions how do you do this where do i find that how do you how do you create something uh how do you create content for 360. and um if you're trying to figure this out online by yourself it's kind of overwhelming and very there's a lot of it's hard it's just a difficult thing to try to figure out yourself so out of a lot of those conversations he was like you know we should probably think about uh creating um a workshop on how to create content for 360 environ
ments and immersive environments and i was like yes please sign me up right away um so over the month of december basically we were talking about what this would look like um and the goals of the workshop were to introduce the art technology behind 360 photography and videography and there is actually a long rich and varied history about humans working and wanting to be in immersive experiences and which i'll show an example that russ gave some really fantastic and engaging lectures on learn how
to integrate photographic and graphically produce content into finished vr applications so basically if you make something what do you do with it where do you put it how do you work with the oculus quest how do you get it on the quest store how do you side load how do you um work with youtube 360. like what are the options there's a lot out there so this was like a really nice guided tour um introducing the students to the specialized cameras and the editing software packages um a lot of people
who started who took this workshop they had never held a 360 camera before they'd never used adobe premiere premiere and by the end of the week the first week um you were you were everyone was actually already making videos and little short films and all sorts of stuff um and the you know the software packages are difficult there's a there's a strong there's a high learning curve when you're trying to learn how to use adobe premiere but also learn how learning how to use it for 360. so we had i
nstructors who were walking people through the entire process how to add captions how to work with the files um so it was really great and then we just wanted you to gain confidence and start um making just making stuff by like day one we just wanted to just jump in and start making things and when we um when we posted this i wasn't sure how many people would sign up but i knew mit folks they love making things just give them tools and let them let them run wild so we um we had a we had a really
great turnout we had 70 people who signed up or expressed interest um but because i was buying oculus quest headsets over during christmas um i could only can only purchase so many so we could only accommodate 10 students and five staff members per the class but we had um people from almost every department on campus we had undergrads we have graduate students in architecture in the humanities in cast we had we had staff members from communications departments on campus from the government of c
ommunity outreach uh we have a research scientist at mit nano who are really interested in doing lab tours so um if anything we will definitely be offering this again um for sure hopefully in person you know we'll see how that goes but clearly there is demand and desire for people to start making 360 content um and working with those uh applications so the way this worked oops let me go back it sent everybody a kit or we delivered one locally that included an oculus quest headset uh the ricoh th
eta 5 which is just a really nice base model of a 360 camera and a monopod you don't want to use a tripod because if you do then if when you look down in your 360 video all you're going to see is um tripod legs so a monopod is a really important tool to get started oops okay sorry and then um our instructors russ assembled a crack team from harvard to come teach us everything we needed to know that included kachina studer who uh is the whiz on adobe premiere and working with files and file manag
ement and sort of how do you make your computer not blow up and start smoking when you're working with these gigantic files um so she helped everyone walk through the entire process from start to finish josh is just uh he's the lead engineer over at the harvard vis lab but he also has just been in the space for so long and he's he was the tech sort of go-to i can't get this to work um and then uh we had a guest speaker jenny gao who's amazing she is a professional she's like one of the world's l
eading professional uh 360 videographers and producers and so she came and gave us a professional perspective on how she gets started tips and tricks on how you know for workflow and how her perspectives on shooting and different techniques that you can use to create really compelling videos um these are some of the examples just i thought it'd be fun to show uh that on day one russ was starting with the 39 000 year history of alternate reality i bet you didn't know this began in the caves but i
t did and then by the end of the week we were at um we were at a history of the future so if your mind wasn't bent by the end of monday it was definitely been by the end of friday it was uh really fantastic let's see so sorry my um let me go back um so the format of the class we offered two uh two-week sessions we met on monday wednesday friday for like four hours each time it was a combination of background lectures like the one that i just the ones that i just showed given context about like w
here we are in history with uh the development of these technologies and then hands-on virtual hands-on workshops about how to create content from beginning middle to the end um so we had office hours if you were on tuesday shooting something and you couldn't make anything work you would just sign in and talk to our instructors and they'd give you one-on-one instruction um we just encouraged everyone to not be precious just jump in to the deep end of the pool here and just start making things be
cause that's how you learn um and then harvard also uh curated a 70 videos and a playlist for us to show the good the bad and the ugly because um if you if you don't shoot correctly or you're not careful with how you're shooting um you're going to make your audience very seasick and they're going to want to throw their headset at you and never use it again so we had to learn learn by watching and imbibing a ton of material um and then we had we kept going with the one-on-one sessions and then we
had at the end of the week after people had had some time to start making some things um breakout sessions with the instructors where we would all show our work and get commentary critique advice sort of like conceptually thinking about how we could improve what we were working on it was really great um and let's see let me so here's just an example of some of our breakout rooms we had some really lively discussions where people really felt that they learned a lot from that um sort of show your
work uh moment [Music] so um the types of projects that we worked on all sorts of stuff this was just a this is just a taste um we have some people who are doing virtual tours of mit nano including one from a perspective inside of a tool which you don't get to see that very often i'll put some links in the chat after to some videos so you can check these out um so lab spaces and tours are always really popular especially in the time of kobit when we can't go anywhere um people were making narra
tive short films that were hilarious and very inventive and just very unique um there's work people are working on creating an immersive cooking class to be in partnership with the kitchen matters series from dmse where students grad students do cook doing a do a recipe and then explain sort of the molecular gastronomy and the physics behind what they're making there are science writers who are trying to get more engaging content for mit news um and then there's people who are working on uh taki
ng objects from videos turning them into 360 objects and then using gaming software and animation software to virtualize those um there's undergrads who are doing just immersive like what is what's it like in the day of an mit grad um weird music videos still in process and much much much more so um what's next we're definitely going to do more of these clearly people are excited and want more of this and i want to continue to learn um one of the next steps is taking what you're working with in
your camera and importing it into a gaming engine and then you can start manipulating things in totally new interesting kind of ways um working with a matterport camera uh russ at harvard is actually virtualizing every inch of harvard and to then import it into a gaming engine and then um just create sort of a complete completely stunning virtual harvard so there's a lot of people working on interesting things in that space and then there's also spatial audio and recording for 360 which was some
thing we wanted to do in this class but we just kind of ran out of time um because that's its own unique art form but um we're really i'm excited to know like what do people want to learn i'm still like learning a lot in this field so um i wanted to ask the question to anyone who's listening what would you like to see are there certain workshops or resources that we could provide um i want to know absolutely facilitate meetings and conversations i think that's a great point um because there is a
ctually a large number of uh vr and ar professionals in the area who are writing saying oh this is awesome like can i i would love to be part of this and know more of this and i think we have the some really excellent convening power at mit to help you know make spaces for professionals to talk and experiment and have a chance to use these tools yeah virtualization of physical objects yeah i think that's you know using the lens cloud um that's something that i would really like to know yeah abso
lutely okay just i'm conscious of time so i'm just going to jump there are recordings i will i will post those um i have uh i don't have it up yet but i will post these yep data visual yep all these are awesome so um yeah i just wanted to wait so the last thing that we talked about in our class was that uh uh russ was explaining how virtual production has been moving towards uh melding the digital with the real and one example of this where you can't even tell the difference is the shooting of t
he mandalorian is actually done not on tatooine or in the deserts of tunisia it is actually shot on a soundstage that has a gigantic led volume light stage um so all they do is like build out the foreground and then the background is completely virtual which kind of blew my mind so that of course that brought us to grogu and um that brings me to the end of this talk which is how we ended our class which is um i hope we see you in person and uh i look forward to seeing what what kind of amazing u
h things that we can create in the space so thanks uh thank you so much sam that was amazing next up we have uh ben moss ben is an excellent top of the class ballroom dancer and he is one of the first users of the immersion lab and we thought he could share some of his insights into using some of these tools for the first time as a user thanks for the introduction for neith i'm a course six alum and my hobby over the past few years has been to be a ballroom dancer and i've also helped to coach t
he mit ballroom dance team so that's really the capacity that i got invited to use the immersion lab and collaborate with pranith to take some physiological measurements to form some insights into dancing and i'd like to share that with you today but before we get into the topic of measurements or partner dancing i wanted to show a quick video to prime your brain on how as humans we use every day our skill to perturb the center of mass of objects to result in movement so the video i'm going to s
how to you here is from a company called matter design which i think is also an mit spin-off and i don't have anything directly to do with them but i thought it was an excellent example so let's watch this video and in the video these people are interacting with these very heavy stones by just slightly perturbing their center of mass and then because these stones are existing in the gravity field that we find ourselves living in it results in movement and some objects are very cleverly shaped to
respond efficiently and usefully to a perturbation of its center of mass but you could imagine also that if these objects were just rectangular blocks that you could perturb the center of mass to move the object but it wouldn't be as efficient or as useful necessarily so if we look at the human skeleton it's a bit uh less obvious but the human skeleton also has a lot of very interesting shapes of the facets of the joints so that perturbations of center of mass also result in efficient movement
dancers intuitively understand how to perturb their centers of mass with skill and understand how the body reacts to those those movements but it's very difficult to as a dancer uh in a normal situation to have an objective reality about the center of mass because it's something we have to infer from our proprioceptive system and we can fool ourselves so what's cool about the immersion lab and what i really i really liked about it is that it provides the tools to make a very accurate and direct
measurement of the center of mass so that we can check our assumptions about things like where the center of mass is so one thing for instance is that uh the center of mass of the human body if i curl myself up into a circle can even be outside my own body if we you know average all of those segments so it's often very surprising and sometimes counter-intuitive where the center of mass is located so one of the things we decided to measure is to take a simple example of a dance figure and to give
you the context of what i'm trying to measure i'm going to show you uh this figure which is a called a tango closed promenade and in partner dancing perturbations of center of mass is a very critical communication skill perturbing the center of mass of either one self or one's partner communicates an intention of where we're going how fast we're going there and other things like the timing and so forth so it's a it's part of the tactile language that gets used between two people in partner danc
ing so let me show you this closed promenade so that you have an idea of what it looks like with a partner so i'm dancing this with my wonderful teacher charlotte jorgensen so there you have an idea of what it looks like so what we did is uh i went to the immersion lab and i put on the motion capture suit and with the motion capture suit i was able to put point markers on various bony landmarks or close to the bony landmarks on my body we had about 24 of those landmarks and then i danced exactly
the same thing that i showed you in the previous video and i have an intuition of myself of where i think i'm perturbing my center of mass but i wanted to see if i could measure that using the immersion lab tools so i'll show you the video of me performing the same action but here in the immersion lab and wearing the motion capture suit so that looks like so so then the next step was to take the data from the motion capture system which gives a point cloud series of points and then extract from
that data where my center of mass is and in addition i'm not going to show it but we also did some calibrations to in order to check that what we're actually coming up with as a center of mass is a reasonable approximation of where we think it should be so here's what we see as a result of the motion capture so this is the point cloud that gets generated from the system and then what we end up having is let's say a series of x y and z coordinates for each one of these points which correspond to
bony landmarks on my body sorry this video has been slowed down so you can see right here that my center of mass goes a little bit off balance and i'm doing that deliberately and i'm trying to see if i can actually measure that perturbation as well i'll show one more time yeah so we did perform some synchronization we took this into consideration especially if we want to use different systems like the force sensitive resistors which in this case were on my feet at the same time as using the mot
ion capture system so it is uh it is a little bit of a complication and it's something to take into consideration is how to synchronize these different systems so that you can uh you can correlate those those series of data but that is certainly possible and it's something that i think most users of the immersion lab would likely do so the next step in the process is that we found some literature which allows a mapping between the center of mass segments of a typical average adult male and what
the approximate mass of that segment would be so what we did is we took the different points and then we approximated a center of mass of each weight segment and i ended up with 15 different weight segments for my body so that's for instance head thorax abdomen thigh shank foot etc and then i end up with essentially a bunch of different a system of particles or a system of weight segments that then need to be averaged out to come up with a center of mass of me as a human so it ended up being pre
tty straightforward to do that in matlab see if i can move to the next slide here and practically what happens is that we did this for each coordinate system independently so that we have a coordinate that re that corresponds to the center of mass of my own body and then what i was interested in doing is comparing the center of mass of my body to a representation of where my foot would be so that would so we used for instance the ankle marker for that one which was located very close to the talu
s of my ankle so then i can see when my center of mass for instance is ahead of both feet in which case i would have perturbed myself off balance in a forward direction or behind my feet in which case i've perturbed my center of mass in a backwards direction so now in this graph what i'm showing you is i'm showing you the ankle markers relative to the computed center of mass of my own body so for instance if both ankle markers are negative that would imply that i've perturbed my center of mass f
orward off balance and if both ankle markers are positive i have perturbed my center of mass backwards off balance and if you see one ankle marker positive and one ankle marker negative then my center of mass is somewhere in between my two feet or within my base of support so this part i've highlighted right here in red is where as a dancer i have intentionally taken myself forward off balance in order to in order to communicate an intention and we also see that in the data so i think we succeed
ed in showing what we were trying to show so the next thing i was curious about and bernie was curious about is to what degree does casual walking have an overbalance and do we use perturbations of our center of mass to communicate intent or to create intention within ourselves so here i'm casually walking i'm trying to do so without thinking about what i'm doing and we were able to measure the same effect using walking so there is a brief moment where by several millimeters my center does prece
de both my legs and it's not as pronounced as when i'm doing this intentionally to communicate a strong intention to another person but it it is apparent there uh which is interesting and i think that we can look at this to try to develop more intuition about how we perturb the center of mass in order to uh interact with ourselves or with other objects in our environment so in summary this is oops this is a demonstration of how we use the immersion labs tools to measure center of mass perturbati
ons and previously for myself at least such understanding only came from my own proprioception and hopefully keen awareness of what i'm doing but certainly that's subject to bias and hopefully this uh style of taking data can deepen our understanding and intuition for the skills that we're using here thank you hey thank you so much ben that was a that was excellent uh so today you heard a little bit about the tools and opportunities in the immersion lab and some of the things we have done and so
me of the ways in which the immersion lab can be used the immerse series is targeted towards creating creating and highlighting more of such uses and experiences and also vaguely around the tools and capabilities of the immersion lab so upcoming seminar series we are going to do something similar in context of athletics so todd carroll a pitching coach from mit we are going to look at a baseball pitch we are going to immerse ourselves in a baseball pitch and the one after that we are going to lo
ok at some wonderful fusion between art and photography and data processing with bullet time and light paint we're going to hear from eric paris he's a bullet time and light painting photographer so you can always reach us at immersion mit.edu and now i'll open the floor for questions i i just wanted to say thank you pranith uh and samantha and ben uh for both the the work that you've done in in using the immersion lab and celebrating uh and also your your words today um so very much appreciate
it um we've been trying to ask or answer questions as we go um so there's a long sort of list of hopefully understandable answers uh in the chat so feel free to either slide over your questions or chat them oh or as prince said send us a follow-up email um and uh we look forward to getting you into the space um we'll pause here for again additional questions uh do we have any gloss-free displays in the lab i don't know what that means but we do have a hololens which is for augmented reality yeah
and all the sensor all the reasons this is again i think one of the questions that i saw was a couple questions about access couple questions about um what's the difference between the immersion lab and other spaces the immersion lab like all of mit nano it's a shared and central facility it's your lab there are costs associated with getting in there we try to offset those and help you with those and and be very creative and getting you to be users of the space so that we can tap into your crea
tivity we're here as a resource you know um in terms of both people and equipment and space so it's our our job to make um our doors open to you and and if you have ideas both for equipment and functionality that we don't have that you think is both of interest to you and a handful of your other collaborators on campus do let us know um and we we want we want to see you in the lab we want to see you doing amazing things so we want to provide the tools and the resources and people and expertise a
nd software to be able to follow your passions so i'm looking forward to working with everybody and and with regards to the question about number of students that can participate in a vr class if you're talking about the number of headsets we have different kinds of headsets and if you don't care about what type it is or what brand it is you can get go up to 30 students and not in did we also for some of the equipment like the the headsets we also you don't have to be in the lab in order to use
it we we will facilitate being able to borrow and take the equipment to your to your space uh brian we have a question do you have some programs for external researchers or artists like residency programs are similar we don't currently have a residency program that's a great idea and so i think certainly something that we can uh consider but there is um like again like all of mit nano it's people both on campus and off campus can become users so there's a process by which you become a user um an
d to get trained for safety and understanding what it is that you're trying to do but the short answer is yes um how we handle on campus users and off campus a little bit different programmatically excuse me but yeah but we certainly um are our resource for the broader community ryan do you see the question in the chat what is the best way to reach out and explore possible capabilities is there an opportunity to visit the lab i think that's a good one it's a pretty if you can go back a slide and
just show the the immersed um email list or email and then also if you hit the [Music] mit nano web page let me see if i can just um real quick post the link for the quick start form is that what you're looking for yeah the quick the quick start form you can go to nano nanousers.mit.edu that's where we list all of our facilities you'll find the immersion lab listed prominently in the menu there and from there you'll find the quick uh the i'm sorry the application form thank you tom so with that
i'd say we're we're close to uh go ahead bring it up sorry if you are at in kobe times if you are on mit's campus with covid pass and have access to building fall we can give you an in-person tour so again thank you everybody for your time and attention today uh and pranith and ben and samantha for your your great uh presentations and words um come back in in about a month uh for april 28th immersed in athletics and then immerse in photogrammetry after that and we also are very much looking for
ward to your ideas um either self-volunteer or suggest for other immersed experiences that we can share with you in the community so with that again thank you everybody and have a good remainder of your day you
