Currently smartphones are the consumer electronic devices with higher growth rate. The wide variety of functionalities that they provide is what makes them so desirable. We can use them to play, to communicate, to take pictures, to guide us, to work, and more. For that to be possible the smartphones have several built-in sensors, which make them much more interesting. This project amis to use smartphone embeded sensors to complement the information given by the smartphones touch screen with information given by the accelerometer and gyroscope. In others words, using sensors like the accelerometers and gyroscopes,to provide new ways to characterize the touch. For that the accelerometer and gyroscope signals will be studied and several algorithms will be create, such as to detect touches using this two sensors, to determine the device position (hand or on surface), the hand and the finger used to touch on device and the touch force.
