    • 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).
    • 公开了用于为多个用户提供公共输入的技术。 可以提供两个独立的输入检测系统。 一个输入检测系统检测用户的身份,而另一个检测用于处理的输入的位置。 由两个检测系统提供的信息被有效地协调,以确定由第一系统识别的特定用户是否在由第二系统指示的特定位置提供输入。 信息可以例如至少部分地基于由两个系统提供的定时信息来协调(例如,两个系统指示的时间是否在可接受的范围内)。 第一输入检测可以被提供为射频(RF)系统,其在用户触摸触摸屏时检测由用户附近提供的RF接收器接收的RF能量的变化。 第二输入检测可以包括APR(声学脉冲识别)或电容式触摸屏(或多点触摸屏)。 还将理解,两个输入系统可以集成到单个设备中,其可以被呈现为例如多用户触摸屏。 多用户触摸屏可以提供公共输入表面,以服务于许多应用。 例如,可以为多个玩家提供具有触摸屏表面的虚拟轮盘赌桌。 玩家可以通过触摸作为公共游戏区域提供的触摸屏表面来与游戏进行交互(例如,玩家可以通过触摸触摸屏的各种位置来进行投注)。
