Visual Translator, and other ideas (Score 1)

Visual Translator: It's a digital camera that can read and translate Chinese into another language. Kinda like a tricorder, but for written material. This requires some real processing power and a pretty large database.

Facial database for people who are lousy at remembering names and faces. This is a twist on a similar idea posted here, but tailored a little more to my own needs :-)

Melody Finder: a training tool that teaches you about melody by turning music into other sensory input. It would be able to recall songs, transpose keys, etc. It helps you learn to carry a tune, and find the beat in a song so you can learn to dance.

Collective Math enhances the math experience by generating semirandom mathematical phenomena, soliciting input, and adjusting itself to create other phenomena. The pdas are completely networked so that one user's input can be share with the others. One of the problems with teaching math is that there's no visual analog for most kids, so they just don't "get it."

Touch Mousepad put a display into the mousepad, so you can pick it up and use it as an interface or drawing tool. (OK, so the crusoe isn't that big a deal for this. So what?)

Trend Finder a neural network app that finds patterns that you might not notice, like changes in levels of VOCs or amount of infrared light, or other hard-to-sense things. You wear it on you. The trick is that it'd correlate several different inputs so you get more useful information.

Visualiser lets you run WinAmp visualizers, but using reality as an input.
