The first "wearable" computer I ever tried was a wrist-strap that let me wear my Palm Pilot like a huge, ungainly wristwatch; I tethered it with a thick cable to a CDMA phone that could emulate a 9600 baud modem and used it to dial into the WELL.
It was pretty great.
Nick Matantsev's Arduino-powered wearable VT 100 terminal is a good candidate for replacing that ungainly, bizarre rig. The 1" display does some cool sub-pixel hacking to get 64 rows of characters (2 pixels/character). You need a separate wireless keyboard to do input, but maybe with the right touchscreen it would accept Graffiti input.
The TinTTY hardware setup is simple:
* Arduino Uno
* TFT screen (1in x 1in ILI9163C), connected via SPI
* USB Host Shield, connected via SPI
* cheap mini 2.4GHz wireless USB keyboard
The input device, by its nature, cannot be too miniature, otherwise it becomes too annoying to type! However, everything else should basically fit onto some sort of wearable wristband or inside a cute tin container. The separate wireless keyboard helps keep the hardware tidy and self-contained.
* explore different keyboard connection approaches
* Lego enclosure?
* wearable form factor?
* glasses mount?

My latest LA Times review is for William Gibson's new novel Agency, sequel to his outstanding 2014 novel "The Peripheral," which marked his return to explicitly futuristic science fiction after his amazing and audacious "Pattern Recognition" novels, which treated the recent past as though it was a speculative future setting.
Snickelsox's guide to playing animated armor that is full of bees is full of surprisingly well-thought-through advice for anyone who should be tempted to role-play such a thing, despite their protestations that "this is dumb."
