TouchSense - Complement the touch information given by the smartphone's capacitive screens with the information received by the accelerometer and gyroscope


The goal of this project is to complement the information given by the smartphones touch screen with information given by the accelerometer and gyroscope. Although using sensors to detect touches is not a new idea, as there are already research which use the smartphone accelerometer to infer which keystrokes were made on a touch screen, and use the accelerometer information to know when there was a tap on the smartphone’s screen is made even before the touchscreen detects it, this project aims to use that information to accomplish other objectives. Mainly gather new information on a touch event in order to extend the smartphone’s touch capabilities with data such as tap strength, smartphone’s holding position while taping (if it is on the users hands or laying on a hard surface) and process that information in order to be useful to the user or the developer party.
