VIRTUAL INPUT SYSTEM AND METHOD

Abstract

The invention provides a virtual input system. The virtual input system comprises a trajectory generating apparatus and a receiving apparatus. The receiving apparatus comprises a sensing module, a coding module, a database, and a comparing module. The sensing module is used for sensing a trajectory information of the trajectory generating apparatus. The coding module converts the trajectory information to a specific code series according to a coding rule. The database stores a plurality of reference code series and a plurality of reference symbols corresponding to the plurality of reference code series. The comparing module compares the specific code series with the plurality of reference code series to determine at least one candidate symbol from the plurality of reference symbols.
