Our gesture recognition system uses a method called active acoustic sensing, which sends out sound waves and analyzes the state of the object using the returned response. This method enables gesture recognition including the internal condition of the human body, such as the amount of force applied, which has been difficult to recognize with conventional accelerometers. It is intended to use this method in a wearable computing environment, and it is unique in that it can simultaneously acquire both externally visible gestures and internal gestures using microphones and speakers that are installed in many devices. For example, we envision that our method can be applied to gesture operations when both hands are occupied in a wearable environment, and to the lifelog of the amount of force applied under stress or other situations.
