Keypaw
The Keypaw is a 12-button input device that provides computer users with an ergonomic, fully-configurable alternative to the traditional QWERTY keyboard.
The Keypaw is a microcontroller-driven device with 12 buttons mounted on two handsets; 1 button is provided for each finger, and 2 buttons are provided for each thumb. Pressing a button or combination of buttons on the Keypaw produces a single character input to the host computer. The Keypaw maps 92 of 255 possible key combinations to the characters that appear on a standard PS/2 keyboard, and it transmits the decoded combinations to a host computer through the widely-supported PS/2 protocol.
A simple configuration program allows the user to customize which button combination on the Keypaw corresponds to which keyboard character. A training program gives users a simple interface for memorizing the key combinations. The configuration and training programs run on the Keypaw's microcontroller and display simple text prompts on the host computer's Hyperterminal program.
The hardware design of the Keypaw provides the user with extensive control over finger, hand, wrist, and arm positions while typing. The two separate handsets allow the user's hands to rest in a naturally curled position wherever the user chooses to place the handsets. Because the Keypaw has only twelve buttons, the fingers and thumbs do not need to move from their resting positions on the handsets.
The software design of the Keypaw was developed with complete customizability in mind. We created a default button mapping that we found convenient for typing English text at the maximum possible speed, because typing English text comprises a large part of our own human-computer interaction. However, because typing English text is not the primary goal of every computer user, the Keypaw's configuration software allows users to completely customize the keyboard mappings to suit their own needs.
