A conventional touch sensor is a binary system i.e. it can only detect the presence or absence of touch. TouchÃ©, on the other hand, is a form of capacitive touch sensing, achieves the above mentioned function and also obtains more complex information such as the hand gesture or body posture of the user by employing the swept frequency capacitive sensing technique. In this paper, the authors achieve the same by using an Arduino Uno board. This is a cost effective alternative when compared to high frequency wave generators controlled by higher frequency processor and other sensors used as touch sensing.
