With a large number of applications including projection notepads that track any pen, pencil or pen-like object; gestural interfaces for devices with inconvenient or ultra-small form-factors or locations (ie-wearable computers); and user identification and authentication through facial recognition, sight-enabled applications in consumer games, premise security, automobiles, military-aerospace, and medical applications. Using these virtual facilities the chance of breakage and infection transfer is reduced. Additionally virtual keyboards require no cleaning and they have no wires, buttons, or switches. All mechanical input units can be replaced by such virtual devices, optimized for the current application and for the user’s physiology maintaining speed, simplicity and unambiguity of manual data input.
Senseboard Technologies (http://www.senseboard.com) further extending the capabilities by providing the technology. The user can type on a hard surface like a desk or table, or into the air. The hand-mounts measure finger two hand-mounted devices that connect to the target computing device with the help of Bluetooth wireless networkingovements and tell the handheld what keys the user intends to press, based on the ubiquitous QWERTY keyboard layout. There’s also a pause function to capture the motion of the fingers and hands, enabling keyboard functionality.
Kitty (http://www.kittytech.com), a finger mounted keyboard for data entry into PDA’s, Pocket PC’s and Wearable Computers. KITTY, an acronym for Keyboard-Independent Touch-TYping, is a fingermounted keyboard that uses touch-typing as the method of data entry. The device targets the portable computing market and in particular wearable computing systems, which are in the need of a silent, “invisible” data entry system based on touch-typing. The new device combines the idea of a finger-mounted chording device (such as the “Twiddler” by the HandKey Corp.), with the advantages of a system that uses touch-typing (such as the Virtual Keyboard by Senseboard or the Scurry by Samsung) References: Canesta(http://www.canesta.com) Developer VKB Inc (http://www.vkb.co.il/) Virtual Devices(http://www.virtualdevices.net/)
