PORTABLE INTERACTIVE WHITEBOARD MODULE

摘要

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.

1. A system for determining a touch point's location within a user-definable region, the system comprising plural modules configured to be movable for a user to define plural peripheral points of the region, an individual module comprising:
a means for measuring an inter-module distance between the individual module and another individual module, whereby the inter-module distance is usable in determining a geometric coordinate of the individual module relative to said another individual module; and a means for making wireless data communication with any other of the modules, enabling the individual module and said another individual module to communicate with each others to initiate determining the inter-module distance;wherein the measuring of the inter-module distance is configured to be performed without a need to physically connect the individual module and said another individual module together, so that the geometric coordinate of each individual module is determinable without a need to have a physical connection between any two of the modules.
