Comments on: A cool use of those tiny projectors … http://www.augmentedenvironments.org/blair/2009/11/29/art-hack-nikon-projector-camera/ Thoughts on AR, technology and anything else I feel compelled to talk about Tue, 26 Jan 2010 03:41:26 -0800 http://wordpress.org/?v=2.8.6 hourly 1 By: elvis_zheng http://www.augmentedenvironments.org/blair/2009/11/29/art-hack-nikon-projector-camera/comment-page-1/#comment-352 elvis_zheng Tue, 15 Dec 2009 14:30:24 +0000 http://www.augmentedenvironments.org/blair/?p=129#comment-352 Thanks for your detailed explanation. I see your points why you think "worn projectors" are not that useful. I have thought about why "so many people are buying into it" for a long time. Maybe because the SixthSense satisfied people's expectations of mobile social interaction to some extent and here the Internet was made alive or "Outernet". From this point, I think social AR or AR 2.0 will attract more attention. Thanks for your detailed explanation. I see your points why you think “worn projectors” are not that useful.

It's a cute grad student hack, with some well put together demos. But, I don't see it as ever working in the way they present it, and I've admit to being a bit surprised that so many people are buying into it. During questions after her ISMAR talk, Pattie admitted that the none of the presented scenarios actually work, they are all just demos/envisionments. Yet, at the same time, she was also unaware of the other work that's been done in this space, especially in Japan, where people use shoulder/head/body mounted projectors (or, in the case of tele-robotics, robot-mounted projectors) to do some of the same things that they present in their videos; of course, those other systems are more limited, but they also seem to work for what they do. In general, I don't see this "worn projector" setup as working. Hang a projector (or flashlight) around your neck; now, go and pretend to do useful things using the image it projects. The image will move around unless you are very still; if you project on any non-trivial surface, the image will by uneven and hard to interact with or perceive; it won't point in the direction you'd like it to point unless you contort your body; lean back, look around, sit comfortably, and it won't be projecting anywhere useful. I think the work of Ramesh Raskar and Oliver Bimber, who do projective AR but in more controlled and well constrained situations, is much more on the mark, and far more compelling.

It uses wearing projectors as output device for Wearable AR, and well demonstrates its pratical usefulness. How do you think about SixthSense?
