What do Texas and mobile device interfaces have in common? Everything’s bigger there. Touch screens such as those in nearly every smartphone and tablet today set a new bar for ease of use. But their fingertip friendliness came at the price of precision compared to the mouse, which could pinpoint things on the screen.
Phree, however, takes a fresh approach to the idea of a pointing device for smartphones. Unlike other smart pens that work directly on the surface of the smartphone or on paper, Phree allows scribbling on virtually any surface and sends its output to the screen and is compatible with existing pen-aware applications.
