His web-page is very well organized. I can figure out from the main concept of the challenge to what this team wants to make and finally how it would work. And his work of concept modeling is nice, and I can imagine how it will be in real one. I think the most difficult problem on making this room might be simulating the tilting motion of the whole room during the challenging. The other thing is that rolling should not be same all the time. It should be reacting opposite way of the movement of people when people try to balance. If his team can find an appropriate instrument to make the room really alive like that, this room is really interesting challenge.

Map: It s not clear what was learned from the map sketch model. Were other method considered for unrolling? I assume the strings would be hidden under some type of casing? I understand how wound-up strings can pull, but how do you push the map back the other way, is there a spring somewhere? System Model: I should assume you contributed one-third? It s unclear what your role was in the system works-like model, so I ll make overall comments. The model addresses the important issue of whether or not the tilting artifacts enhance the user s sense of rotation, which artifacts are most important, and which can be improved. The preliminary tests with 3 users provided important results. I imagine that more can be learned by testing with a larger number of people, or by testing multiple times with the same person since the test is repeatable even if the volunteer knows what you re trying to learn from the test. One important question that can still be asked is: how far can artifacts be tilted without people realizing that it s a fraud?

Well done with the full size model. It answered a lot of your questions. How well did the scroll movement work? I don't recall seeing it during the presentation. Adjusting the model so that the string does not show would also be useful as it doesn't seem completely obvious how it would be done.

The rolling and unrolling map is a really cool idea. I think that it would definitely add to the feel that you are really tilting. Did it work very well? You didn't seem to mention much on the site other than the fact that you made it. I got a little bit of a sense that it worked from the presentation, but I didn't get to see the device. A little more information would have been helpful. Good idea though. The overall system model seemed to work really well. Having people test out the room was a good step. It helped to show what things were really useful. I was skeptical if tilting the items on the wall and ceiling would work well enough to convince people, but the test results seemed to say that it would. I think that the most difficult part of the system model to implement will be the porthole. Like Taylor mentioned in the presentation, it would have been easier to do if the tilting were on a different axis. It might be a good idea to move the porthole to a side wall.
