the and and we all and we have and you know you want to enjoy numerous and I and I apologize for that was that was used to be a joint presentation with my colleague called proIraqi at the leave for Spain just a few moments ago installed in my back to to pretend as we're going to have but just keep in mind that this was the 1st time a country so long so can we have p the the image of so the paper like to prevent the goal of eliminating claim and this is a tangible interfaces with potential graph applications and all describe a little bit more about what I mean about this give you a flavor of this is an image of the of the of the interface here prison and that the head of about a year and a half long collaboration and the Tangible Media group within the MIT Media Laboratory which is a department within MIT which deals with technology but also some social issues and and in this case we're looking at how integrate can be developed around the design criteria those were we're not from GIS background in but both and I are trained in an architecture original and then but having some problems with the quite but so and yet we were both kind and an
02:31
architecture and and we're interested in and looking at how we can use the power of physical modeling materials and you like that within the in the digital domain and what is the use of physical model material well the redirect a designer will tend to use cardboard play around object to express and intentions and that there are many advantages over
02:57
working in a purely digital form and and in such a way as to direct spatial representation and and so forth and and you can see here some of the some of the advantages of working in a physical way you manipulation of the clear communication if you're working in collaboration between some experts and or perhaps through the client and and especially at the physical model offers a very useful platform for discussion and as I mentioned before but because physical model is in essence the spatial construction it it can convey spatial relationships are easily on the other hand we we always have this digital revolution and that the reason there are many but perhaps it's partly because of the greater precision the use of distribution and you make a digital model that can be shared around the world are usually over the internet and of course and most importantly concerning the particular community and the ability to quantitatively analyze that Digital model what you want you have it in digital form so the question that we set out to to answer was how can we merge these 2 very powerful forms of representation physical and digital and this is not a new idea many people have tackled this problem in in the eighties guy creature developed a system of building block which you can physically get together and the computer was aware that the spatial relationships and and then 1 could analyze the spatial relationships with with the computer very digital that were developed where the physical media such as paper rulers and will be used as input devices to the computer but then there were nervous of neural surgical interfaces work dealing with that the the problems of having to visualize complex threedimensional geometry of the human brain and in any 1 of these I can go into more detail if you like to talk afterward the urban planning workbench which I'll talk about in a little bit more detail there some were created that tactical already where
05:14
holographic images of models have been combined with the violence that can give some at the compression of about object and and finally Shader Lamps which also just talk about all of this becomes a little bit more clear with with some images here we have the urban planning mentioned and the way this is working on it's a clear physical model here in this case representing a building and that is tracked by a computer vision system and then a dynamic simulation relate to sunlight shadowing or when the simulation you continue white lines passing through here is calculated in real time so that the user is able to manipulate physical objects and see the effect on some form of dynamic simulation this is an interesting relationship because you're starting to combine the power of forms of representation it is somewhat limited and In this case can only providing a 2 dimensional analysis so the
06:18
when you see here that there was a change in the trend for example that would not be registered there's been some other very sophisticated work looking at how 1 can projected onto threedimensional surfaces of objects in this case at the physical model of the Taj and the color of the year there
06:39
is just a jacket on on and they again you can combine some of the power of both forms of representation and finally leading up to eliminate play when we were looking at the possibility of projecting the construction construction template into political space when building models using that be In light of regions of Italy indicating where users to play with LarKC the final blow the here model of an example but the problem had there was that they did with the computer with state the user this is what we should do next this is where she didn't really want you
07:18
to be able to manipulate them physical form the computer that helps the user in constructing the form that's worth underlining claim want to take is that the power of physical modeling material and that the direct and the use of communication and collaboration and so
07:40
on did you like that in some manner and that digitized model and then we reprojected the analysis back onto the surface of the physical model so that this is both the
07:51
input and the output of a system and at this point start to think about the application domain with initially started more data architecture perhaps in industrial design but the landscape landscape analysis slanted designed really presented itself the very very useful the area is going to go because there were already a great number of analysis functions we can easily or in the the story about but it's inherently spatial problems and in a way that the technical issue but most importantly the fact that landscape and be a continuous surface in that we can avoid the problem of occlusion overhang people which in
08:39
the case of industrial design environment for the error for example year and also to problems so I'd like to show you a short video which should make that a little bit more clear at at
09:03
OK intractable physical and computational representation of it there we go into the blood British preparing landscape model the analyzed David
09:24
900 with all the latest and a lot of the quality of the model to capture the rate of 1 and the whole thing at the end of the year that
09:37
the value of this group is in the form of a model
09:43
experiments with different types of environments but he was not called by allows the model to maintain the required for this the only thing that function in the action but
10:03
even
10:07
the structure of the function of the number of edges relations you sharing the approach of and have and generation of
10:29
information the question the value of the environment I would
10:45
think should the nationalism and the unintelligible to the left of the environment and development of innovation harmonization and on and on the all the architecture and a little bit more detail level of projector yeah and a little energy and variability standard capturing the geometry of the model and then the analysis of the geometry of the projected down and they do have the control within the within the software that firing related repeatedly and we get a rate of about 1 per minute built for a single again but there are standards in the market that 30 frames a 2nd so and they the the geometry of the model is converted into standard EM elevation twodimensional elevation model and analysis functions
12:02
form of open GL and with the columns exactly the on 1 of the advantages of working with this kind of intervention that all the technology is concentrated in the ceiling you got to start doing with adding more specialized materials you can really take whatever is most suitable for your particular project the cardboard where they're playing with a laser highly accurate models this some complex ability and the the gas is capturing the geometry of whatever is in the working environment and that's really again get back to this idea providing and that computer based interface that allows for collaboration for people to gather around the table working very physical indirect way much of the software that we discussed them over the past few days highly specialized and difficult to get somebody to come in and really play a a key role when look at this huge amount of specialized knowledge that 1st budget over some of the analysis functions not into much detail because during your familiar with you these kind of things here we have the basic elevation rejected and there's a lot of down on model and incidentally In the section here here the lon
13:30
and but you can click on them and projected onto the model I
13:40
and applicable and chattering very critical especially more architectural domain where it maybe starting and look at chattering in urban situations 4 years you want to investigate the crops areas and so on but thing and they're all very a rudimentary but that were
14:09
potential that a water drainage over the last and the Continental again for a design purposes can be very critical the whole aspect of how much of project will come this was also useful in terms of sculpting the original model to be analyzed for example if you have a slight you know the the geometry how do you get that into the proclaim model where can that we plotted out the 3 D plot that would make a model that 1 way of doing that is to I like the difference between the digital representation the political representation using the color of teaching experience with that our reverting to the the reality of using something like that in the classroom situations and so forth the main result of this interesting we've learned a lot about the reality of trying to so teach with with such an new and and at the end of someone at on the results but we wanted to we want to involve people from the beginning of that those kind of ideas can influence the direction it goes on and we would like to get out more similar kind of classes have but that really we want to take it forward and I'll talk about so but what what what we have here what advantages well 1 of the 3 dimensional display people there working on threedimensional display for a long time so this the holographic kind of display 3 D goggles and so forth but often very complex and expensive systems and here we have really with the 2 . 5 the display because of course you can't display on all services of a physical object and but you can only square on a continuous 2 . 5 service which indicate a blanket it is useful and we have this on the these of threedimensional in the system so you have an image of someone what being added and represent building or even maybe magnetic field generators they and and and and the ease of manipulating the the clay this is a very direct after the and the dimension
16:47
it's going to be useful teaching platform so where are we presenting today in the community MIT basically we come from a computer interface design background that with the beginning design in architecture but at this point we would really provided a platform for other kind of testing and and we're very very interested to get much more sophisticated analysis functions involved here and and that you were really trying to attract interest from from other people within the graph community the potentially could be very useful for new software development because of the directness 1 can really see how changes in the triangle effect 1 simulations and rather than plugging in new datasets over time we can actually the degree manipulate the clay and see the results on on an function and other teaching platform again owing to the directness an interesting to watch students are granted students to often been talk about dynamic forces in the landscape but it tends to be in one's imagination when the thing is represented down on the table it led a whole new sense of reality to align that models so becomes able to see it to the over a period of a week or seal and given the period of the year and then have those dynamic what is represented it is a so please approach may afterward if you have an interest in in working with the system would be delighted to but you know more about it and I just like to thank you the In this is really the result of a great deal of collaboration and especially William Mitchell beginning from MIT Media funded of the latest at 1st and and and these could be eliminated which were in the undergraduate research is that we earlier the the planet there is any questions of about how and how part had I I read the had time I and world I will really and 1 of the major sponsors of the lab where we work with the and then they come through American of knowledge that thing so how you know we have all of this processing power of the and we got these curves of that we can predict that processing power and low enough that we don't have been an application for a minute we can justify on all this money into we laughter chip and let people are coming up with this kind of ideas that will justify the and and really I don't think that computational the should even really an issue at all because if you think about the last 10 years you know that's going to go on and and it actually I'm sorry I'm not I'm not a real experience in an area that can give you the bigger number of but I think we have like another 4 years of of growth in in a similar direction of an adventure that people here that would be able to give more precise answer right but I think here what we're trying to do is give a vision of what computing can be about and then we're not worried about being the actual engineering at because that seems to be looking after itself in terms of speed time we claim that on on that and then there's I and I randomly assign IBM model you know like how many relevant columns or will make making small and 1 possible application and I lost about 1 example of you may experimental sentiment that book and you have you needed you put it back near your lab and use the Indian time after the simulation how we modify modified use of the on the bottom up if you it's possible only if you up as so what if within the water with this kind of communication and who was so we suggest
22:33
comparing an actual real life with simulated flight out in your in your laboratory well and you can you hear in the letter and then go through the wall or through the cemetery and transparent materials so you can see here area time in time that things are moving but that's the Japanese that is on the use of these so 1 of the things that were were thinking about and so far the human going and physical and the computers coming out visual and it might be interesting to thing about the computer coming out of the so we're looking at materials that that could dynamically so for example if you were to run some kind of it was a big problem that we want to run the water erosion simulation the only way we can represent the change in the landscape display color that a while the region but rather than the lower region of the world about that but where we have been looking at you know these these systems of of in that it would actually happens maybe Arab bladders or even a little magnetic fluids and providing different magnetic field the and and being able to do that actually have physical out not simply visual of you
24:08
and I guess you already can partly answered my
24:11
question I really appreciate that ideal
24:14
playing golf you like having their claim eliminating world but they did in the in the in the in the in the cannot really play got to put it to use what we have in the reality and he tried to come up with more from real possibly highresolution digital elevation models the accumulation of we have that but actually it 1 of the biggest problems with that and when we ran the collapse of there is the right and then nobody wanted to build a model you know that Digital would not have the physical model of the beginning and there is a whole lot of discussion of what should be done the building cardboard and layers of cardboard relatively accurately people want to do that you can you can and another thing our ability or something like that so 1 possibility is using the 3 plot you can actually yeah the plot with what and then you have to go there and then you can build and change around and and just at the moment we didn't have that application that would highlight the differences between the digital digital model and the model for example we can and take and and we tried to build a they but by highlighting OK were within the volume or outside of my thinking about you know what a great way to make very realistic portraits but it just came out of the variable or the kind of thing and that's what the accuracy of the latest data is not efficient to using the light of the
25:55
construction FIL 1 of left look you prevent adopted just the kind of flat and indicate that the device that he presently used in engineering and in the autumn mobile industry but said that you had mentioned it to you in the eye and the employer India to you did you ever knew every case that means that that the fact that handkerchief and modify in the in the what what that advantage of of using a cane and the following were among threedimensional view of early but and that's where the there is there is that initial idea of trying to concentrate the technology and 1 because if you have a case you have these projectors and you have a special walls and you have a limited dimension and that all very well for a particular application but if you want to move you want to look at a landscape that 20 it's like 1 meter and you have to building a brand new procurement model that this then you have to readjust and and the idea of using the the camera and the projector of the same source conceptually we're thinking of a more like a torch suppose that had the ability to information and project information and then we quite consciously decided not to and that technology use using data clustering you position tracker within within the physical model because we wanted to maintain that that immediately of materials like like we really touch and and also the legend has it that it is coordinated by organisms have special material that you can only by this 1 place the color of amount of money and then you lose all of the director of the working this includes recall geometry but with a system like that and then we can have a discussion about it and if you have a favorite the our unit and in some cases you put your hand and you can immediately some changes in the million thank you for your interesting presentation I have 2 questions I mean when a question and 1 suggestion on the hurricane band it is that the solution is presented here and that can at ecology especially department of Geography of the however many model made of by the over of landscape features as valley of the value of and anything goes models of precise to some degree you can even a calibrated model to visualizing the morphometric parameters which are possible on that all using those models so that my suggestion to the president and the 1st question that will the Ministry of the project we we had the idea and we're and we didn't want to spend a lot of time developing presenting technology because later energy and the reverse component parts of the projector just a miracle later camera and some software to look at how the data stories but they're expensive because of the specialized market and they can charge with what they needed so that they can only 45 thousand dollars which we we were happy get than we could just start the program recently we developed another completely different sensing technologies because we wanted to to allow anybody with a lot of and where can we have the same being at this kind of use of computers so that's what we did was you know that any of that can be very sensitive to infrared light or most of you and you can remove the filter and they become basically broke cameras mounted but above stand and then we're back with the standard we normal halogen light bulbs with intensity that the infrared light and factor and where the values in the sense there's more incorrectly where the mountain and there's lot but get a great damage of that and and then you can run exactly himself parameters village and it's a very cheap way maybe 200 dollars to special our cultures and but you can add a similar effect for 200 dollars disadvantage that you can take things like paper or whether hand because of course the whole of of Europe but you can you can teach some basic lessons for example about you using an and if anybody's interested in we have that that person is functional in part electronic which is optimal in terms of and and I'll be there the next year so if anybody would like to understand this and and actually play
31:48
around with it on that would be it was it will
