Foldable Interactive Displays
By Johnny Chung Lee, Scott E. Hudson (Carnegie Mellon) & Edward Tse (Smart Technologies)
Summary:
This paper discusses how portable displays can be implemented on foldable, non-traditional display surfaces. They utilized image projection and tracking capabilities through a PixArt camera to build their prototypes. The four foldable designs are described below:
1) Newspaper – This prototype is highly intuitive due to the large portion of users who are familiar with the newspaper format. It was able to show from one-half of a page to two full pages in a side by side manner. Also, the user can alter the display screen by folding or unfolding the paper.
2) Scroll – Scroll use is less popular than newspapers, it is still a valid format to use as a prototype. One benefit of the design is that it can easily be compacted into a small storage space but still allows the user the ability to choose a display screen size.
3) Fan – This design is the one the researchers feel will be the most easily adaptable to a mobile technology. It offers sufficient display size while being compact and foldable.
4) Umbrella - Even though this design offers a large viewing area, it seems to be limited by the handle in the middle of the display. However, it has the potential to fit into many applications.
Lastly, the researchers allowed for interaction through a stylus and offered multiple viewpoints depending on the display’s movement/tilt.
Discussion:
I found the idea of foldable displays to be quite interesting. It is easy to imagine that you could fold up your screen and place it into a drawer or your pocket. The prototypes appear to be colorful and lightweight...I think I like the newspaper prototype best. Also, the tracking implementation seems fairly simple and inexpensive. I would have liked for the article to have contained a user study to show how a typical user would interact with the device.
