GesturePlus™

VTI's Gesture Recognition System

GesturePlus™ is an easy-to-use gesture recognition system that uses joint measurements from a Virtual Technologies CyberGlove instrumented glove to recognize user-defined hand formations. During a simple training procedure, the GesturePlus system learns to associate the user's hand formations with the output symbols of the user's choice. GesturePlus allows the user to define large customized gesture vocabularies for his/her applications, such as the 26 hand formations needed for the American Fingerspelling Alphabet. After training, the system is ready to use, outputting the recognized symbol whenever the user makes the corresponding hand formation.

GesturePlus interfaces as a hardware device connected to a host computer via an RS-232 serial port. The GesturePlus system performs all the CPU-intensive calculations needed for its state-of-the-art gesture recognition algorithm, freeing up the host computer to manage a virtual reality application or analyze data. The interface to GesturePlus is a set of simple commands which are executed by the user's application to initialize and run the recognition. GesturePlus also allows applications to retrieve the raw joint angles from a CyberGlove while recognizing gestures, so a graphical hand model can be displayed simultaneously.

Applications

GesturePlus provides hand-based control input for applications in such diverse areas as virtual reality, computer operating systems, task training, music generation, telerobotics and sign language recognition.
