FlashTouch: Touchscreen communication combining light and touch

FlashTouch is a new technology that enables data communication between touchscreen-based mobile devices. Touchscreen can be used as communication media using visible light and capacitive touch. We designed a stylus and small case modules for collaboration using touchscreens. With these modules, users can easily transfer data from one mobile device to another. This technology realizes non-wire or non-wireless communication just using touchscreen as a communication medium. The achievement of FlashTouch are summarized as following: 1) Easing data sharing only by using stylus device. Mobile device receives text data from touchscreen then there is no need for optional wireless or wired connection. 2) User identifies data sharing operation as like picking and dropping data by dropper. 3) User can capture data on the screen because it is displayed on screen to be operated.
