  • Patent number: 9465486
    Abstract: A system for determining a touch point's location within a user-definable region is provided. The system comprises plural modules. In a set-up stage, a user positions each module to define a peripheral point of the region. Exemplarily, a module comprises a means for detecting alignment between the module and another one, a means for measuring an inter-module distance, and a means for making wireless data communication. In particular, the detecting of the alignment and the measuring of the inter-module distance are configured to be performed without physically connect the two modules together. Hence, a geometric coordinate of the module relative to the other one is determinable without a need to physically connect the two modules. The system can thereby be compactly packed for traveling to give an advantage of high portability to a portable interactive whiteboard system that incorporates such system.
