Projection Keyboards See the Light
Canesta has begun to take the wraps off of its electronic perception technology. One of the first applications that made possible is a projected virtual keyboard that can be integrated into mobile devices such as PDA's and smartphones. The comany expects products to incorporate the virtual keyboard chipset by next year.
The chipset, when integrated into cell phones, PDA’s or other mobile devices, enables such devices to project the image of a keyboard on a nearby flat surface, and then read the finger movements of a user who types on that image, as if it were a physical, full-sized keyboard. Canesta’s electronic perception technology resolves the user’s finger movements in real time into keystrokes electronically provided to the device.
According to details on News.com, the chipset consists of three basic parts: a light source that beams a blanket of infrared energy onto a surface, a sensor that tracks finger movements, and a pattern projector that displays an image of a QWERTY keyboard in red. The sensor, the key part of the equation, pinpoints where the light is reflected. It then transmits data about where reflective surfaces (the back of your fingers) move and stop. The processor then translates this into keystrokes.
