Under the FingerWorks iGesture Pad are sensors and a hidden microprocessor that interpret your finger movements, translating them into mouse-pointer motions or shortcuts. Motioning with two fingers mimics the control of a standard mouse, and touching with three fingers invokes a left click.

Shortcuts for functions like copy and paste are accomplished by pantomiming simple choreographed gestures. For example, by pinching your thumb and middle finger together on the pad, you invoke the standard Copy command. To paste, slide your thumb and middle finger apart. And as a fully functioning number pad, the iGesture might help you calculate a way to fit it into your budget.
