Hand-Held Keyboard

Abstract

The Data Egg, a prototype chord key-based data entry device, can be used autonomously or as an auxiliary keyboard with a personal computer. Data is entered by pressing combinations of seven buttons positioned where the fingers naturally fall when clasping the device. An experienced user can enter text at 30 to 35 words per minute. No transcription is required. The input is downloaded into a computer and printed. The Data Egg can be used by an astronaut in space, a journalist, a bedridden person, etc. It was developed by a Jet Propulsion Laboratory engineer. Product is not currently manufactured.
