#1204: ShadowScreen

Today’s invention is a possible enhancement to existing touch-screens. A stalk-mounted lamp on eg a mobile device casts shadows of one’s fingers onto the screen.

When the shadows are seen by a small embedded camera to lie on certain screen elements, these are primed in the same way that normal rollover scripts work in a webpage.

This allows eg each key displayed on a small cellphone screen to grow as a finger approaches it, in order to make dialling easier.
