FrogPad - Mini Keyboard One-Handed

FrogPad is a small chorded keyboard about the size of a numeric keypad that can be used with one hand. The keyboard is optimized by character frequency. 85% of average keystrokes in English text can by typed without chording, and chords are limited to 2 fingers (opposable thumb and one finger). As a result, the FrogPad has many more keys than a GKOS or Microwriter or Baudot keyboard but many fewer than a conventional computer keyboard.

All right all you one-handed typists, tear yourself away from all that porn for a minute and take a look at this: here's the FrogPad iFrog Bluetooth keyboard, targeted for use on the road with UMPCs and smart phones. Designed to be used with one hand, the iFrog has a so-called patented ergonomic layout, putting the fifteen most-used letters in the English alphabet front-and-center. This scheme reportedly still gives you 100% of the functionality of a regular old QWERTY keyboard.

The 3x5-inch keyboard can be worn on a sleeve with its included Velcro straps, and folds up and tucks away when you're not using it. Trying to talk us into this idea, FrogPad says it takes 10 to 12 hours of training and practice to achieve a 30 to 40 word-per-minute typing speed.
