PINCH™ Gloves

The PINCH glove system provides a reliable and low-cost method of recognizing natural gestures. Recognizable gestures have natrual meaning to the user: a pinching gesture can be used to grab a virtual object, and a finger snap between the middle finger and thumb can be used to initiate an action. A hand-gesture interface system that allows developers and users of immersive applications to use hand interaction to work within the virtual environment.

The PINCH system uses cloth gloves with electrical sensors in each fingertip. Contact between any two or more digits completes a conductive path, and a complex variety of actions based on these simple "pinch" gestures can be programmed into applications. Fakespace provides additional products and services for virtual environment technology including hardware integration, software tools and peripherals.

The PINCH system includes a pair of gloves, interface electronics, user's guide, tracker mounts, and software. The standard RS-232 serial interface allows the PINCH to be used with virtually any workstation or personal computer. Gloves are also available in personal sizes and colors.
