This paper presents an effort of developing a wearable gesture recognition system. The objective of this work is to design and build a mechatronic device that can recognize human gestures. This device can be used to help the communication between humans or humans and machines (such as unmanned vehicles). The device is composed of two main components, a data acquisition system and a gesture recognition system. The data acquisition system obtains sensory information from human motions and encodes the information for transmission to the gesture recognition system. Upon receiving the signals, the gesture recognition system decodes them such that machines can respond to the corresponding human motions. The project was conducted by a group of Mechanical Engineering students in the format of junior/senior engineering clinic. Through this project, they obtained working knowledge of a mechatronic device within a cohesive and dynamic team.
