Study on different touch object recognition algorithm based on Android and capacitive touch panel

Nowadays, touch panel technology has become the mainstream of human-computer interaction. Based on a smart phone equipped with Atmel's latest touch chip — maxTouch874 and the Eclipse software, a system that can gather the original signals from self-capacitance and mutual-capacitance is developed. The recognition of four kinds of touch objects is achieved with the different characteristics of different touch objects. The test result verifies the accuracy of the algorithm.
