Abstract :
In this paper, we present a new wireless input system which accepts all kinds of natural handwriting images written or drawn on paper without using a touch pad. This technology can apply to an input system of graphic user interfaces and MMS (multimedia message system) for computers, PDAs, cellular phones, and other telecommunication devices. A real-time digital signal processing SoC chip has been implemented for 2-dimensional position tracing technology based on PVDF film piezo sensors and IR sensors. The system is compatible with any mobile devices for maximum proficiency.
