## Abstract

A headset controller takes a first touch sensor, a second touch sensor, a first pressure sensor, and a second pressure sensor as a control medium for users. The headset controller can generate four different output instructions by the users touching or pressing the operating interface. The headset controller integrates various sensing methods to generate the needed output instructions.
