Techniques for providing a common input for multiple users are disclosed. Two separate input detection systems can be provided. One input detection system detects the identity of user while the other detects the location of input for processing. The information provided by the two detection systems is effectively reconciled to determine whether a particular user identified by the first system has provided input in a particular location indicated by the second system. Information can be reconciled, for example, at least partially based on the timing information provided by the two systems (e.g., whether the times indicated by the two systems are within an acceptable range). The first input detection can be provided as a Radio Frequency (RF) system that detects a change in RF energy received by a RF receiver provided in the proximity of a user when the user touches a touchscreen. The second input detection can include an APR (Acoustic Pulse Recognition) or capacitive touchscreen (or multi-touch screen). It will also be appreciated that both input system can be integrated into a single device which can be presented, for example, as multi-user touchscreen. The multi-user touch screen can provide a common input surface to serve numerous applications. For example, a virtual roulette table with a touchscreen surface can be provided for multiple players. The players can interact with the game by touching the touch screen surface provided as a common playing area (e.g., players can place bets by touching various positions of the touchscreen). |
