A wearable human gesture sensor with enviromental universality

The present human gesture measurement approaches have inadequate performance for the environmental universality and the system complex of joint with Multiple Degree of Freedom (MDOF), which result the status of laboratorial measurements, or outdoors with short time and short distance. The paper presents a novel wearable 3D joint sensor with outstanding universality for both static and dynamic environment. Single sensor can measure MDOF of joint simultaneously with a flexible structure, which enables the gesture measurement of complex joints with less restraint. The angular parameters are converted to the linear displaces of wires with three DC voltages as outputs. Its simple reconstruction algorithm also provides the capability of a real-time evaluation.
