A Novel Hand-Gesture Recognition Method Based on Finger State Projection for Control of Robotic Hands

This paper proposes a novel method for hand-gesture recognition based on finger state projection, called FSP Method, which is used to control robotic hands. The control system using FSP Method can simplify the control process of robotic hand considerately while avoiding the drawbacks of traditional hand-gesture recognition methods. The FSP Method measures the projection length of fingers through a monocular vision to infer the state of fingers, and therefore the angle of each joints in fingers. The information is used to control the motors of a robotic hand and make it to pose as is wished. The experimental results show that the FSP Method is effective. The FSP Method does not need lots of study work which is almost required by traditional methods, and the FSP Method has higher adaptability and bigger recognition range than traditional methods.
