Project Touchport: A system consisting of a portable touchscreen to convert any computer screen to a touch sensitive screen and a wearable wireless device to remotely control your computer

摘要

Project Touchport is a complete system that makes the human-computer interface convenient, simple and wireless. The system consists of two modules, the touchscreen module and the remote module. The touchscreen module can be used to convert any regular computer screen to a touch sensitive screen, eliminating the need for a new touch sensitive device. The remote module is a wearable device that can be used to control the computer from a distance by means of gestures. The system employs the technique of Sweep Frequency Capacitive Sensing (SFCS) in which a range of frequencies is applied to an object and its capacitive response is measured.
