Insert Coin: Prototype peripherals incorporate no moving parts, multitouch functionality and freaking lasers
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. When in doubt, strip out the moving parts and see what you wind up with. This is the idea inventor Jason Giddings is following as he turns to Kickstarter to help fund the prototype creation for a glass keyboard and mouse, both sporting multitouch functionality. The design uses the same biometric systems that currently capture fingerprints on assorted trackpads and keyboards, and uses a technique known as Frustrated Total Internal Reflection -- which incorporates a series of LEDs on the bottom of a device -- to bounce infrared light beams around the inside of the glass. This process is interrupted when a finger touches the glass, wherein a simple embedded camera captures the event, processes where the keystroke, mouse click or gesture took place and relays the signal to the computer.
