    Pinch Keyboard: Natural Text Input for Immersive Virtual Environments
    Bowman, Douglas A.; Ly, Vinh Q.; Campbell, Joshua M. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2001)
    Text entry may be needed for system control tasks in immersive virtual environments, but no efficient and usable techniques exist. We present the pinch keyboard interaction technique, which simulates a standard QWERTY keyboard using Pinch Gloves™ and 6 DOF trackers. The system includes visual and auditory feedback and a simple method of calibration.

    Using Pinch Gloves(TM) for both Natural and Abstract Interaction Techniques in Virtual Environments
    Bowman, Douglas A.; Wingrave, Chadwick A.; Campbell, J. B.; Ly, Vinh Q. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2001)
    Usable three-dimensional (3D) interaction techniques are difficult to design, implement, and evaluate. One reason for this is a poor understanding of the advantages and disadvantages of the wide range of 3D input devices, and of the mapping between input devices and interaction techniques. We present an analysis of Pinch Gloves™ and their use as input devices for virtual environments (VEs). We have developed a number of novel and usable interaction techniques for VEs using the gloves, including a menu system, a technique for text input, and a two-handed navigation technique. User studies have indicated the usability and utility of these techniques.
