This post is in response to the following paper:
Walther-Franks, B., Schwarten, L., Teichert, J., Krause, M., and Herrlich, M.
User Detection for a Multi-touch Table via Proximity Sensors.
Extended Abstracts of IEEE Tabletops and Interactive Surfaces 2008, (2008).
One possible application idea from this paper would be adjusting display orientation based on the presences and positions of the users. The base case would be: for one user, the display follows the position of the user. And a developed case would be: for two users, the display aligns somewhere between the users or split into two displays, each of which falls into the base case. And more sophisticated cases would be more interesting.
