Abstract

An ambidextrous, single hand data management device that has been ergonomically optimized to facilitate multiple key per character input, chording. The device has an arrangement of multiple keys which are so situated that the device can be held in either the left or the right hand, by a large range of hand sizes, and data can be quickly and conveniently input, that is, any combination of keys can be quickly and conveniently actuated with a 'Microwriting' chordic type of data input, without a hand strap and without dropping the device. The ergonomic arrangement of keys on the casing allows for the device to remain stationary relative to the palm of the hand while that hand is in a multiplicity of orientations. The device can serve as a primary data input device or as a data storage and retrieval device for things like inventory control, names and addresses or daily schedule reminders or, as a combination of all of these. The device is primarily a mobile data input device that allows access to the entire keyboard of characters without the need to look while data are being input but which provides a visual feedback if desired as to what is being input with an LCD. The information in the device can be conveniently and easily uploaded into a computer via a serial cable adapter.
