The multimedia interface using "Paper": Ultra Magic Key
Hiroshi Usuda, M. Miyazaki · 2002
We have developed a new multimedia interface called Ultra Magic Key which uses "Paper". The new interface will allow users to access multimedia information simply by "Turning over a Paper" or "Touching a Paper". The "Paper" sheet has no electric devices or batteries. The system recognizes the "Paper" sheet and the action of a user's finger by image processing. All the information printed on each "Paper" sheet is hyper-linked with each TV channel and AV/IT device.
