Foldable Interactive Displays

Comment

Portability has become very important in electronic devices. It used to be that you could just make a device smaller to make it more portable, but our electronic devices can only get so small. Johnny Chung Lee, Scott E. Hudson and Edward Tse have done research in the area of creating foldable displays.

In this paper, they created four different displays. They were a piece of paper, a scroll, a folding fan and an umbrella. All of these had IR emitters placed on them in places so that they could easily be tracked by a camera and have a screen projected on them. Since the camera they were using could keep track of four IR emitters, by placing them in the right places, the camera could detect if the paper had been folded and adjust the size of the projection. The camera could also use the IR emitters to determine the orientation of the display.

I think this would be good for researching how to create usable foldable displays once the device itself can display the screen instead of needing the screen to be projected onto it. As they are right now, you would need to carry around the camera and projector with you making it not very portable.
