ABSTRACT:
A data input device that substitutes for a traditional keyboard employs the same finger and wrist movements that a user employs on a keyboard but without a keyboard enabling a user's hands to rest comfortably in the user's lap or otherwise as the user may choose. Finger positions are identified for symbols and commands by tracking a user's wrist movement in pitch and yaw, which when combined with traditional finger movements multiplies the number of positions representative of symbols and commands. The data input device thus identifies and communicates a full set of symbols and commands of a traditional keyboard to a computer processor. The device typically employs a glove adapted to fit snugly on a user's hand outfitted with necessary switches to track the user's finger and wrist movement. With the finger and wrist moved to identify a selected symbol or command, a dichotomous finger switch connected between the metacarpus and each finger is actuated by downward movement of a finger similar to that employed in operation of a traditional keyboard. Finger and thumb movement is tracked between at least three pitch positions. Wrist movement is likewise tracked between at least three yaw positions and three pitch positions.
