VIRTUAL INPUT METHOD AND SYSTEM

摘要

The present invention relates to a virtual input method and system, comprising an information reception end for acquiring inputted information, an operation end for input operations, an operation surface on the operation end for inputting, and a control unit for input control. The present invention defines input areas in a virtual input system, assigns one type of input information to each input area, and thereby directly electronifying the input information. The present invention enhances the conventional ultrasonic wave input method, and completes, using a simple method, the electronic process of tracing handwriting using an ultrasonic input method.
