Wearable data input device employing wrist and finger movements

A keystroke communication device simulating a keyboard and adapted to be attached to a user's fingers having finger metacarpal, proximal and distal joints and proximal, intermediate and distal segments, a thumb having thumb metacarpal and distal joints and proximal and distal segments, and a metacarpus of the user's hand and to the user's forearm to track the user's wrist and finger movement as keystrokes but without a keyboard, comprising,

• a forearm member attached to the user's forearm,
• a metacarpal member positioned at the metacarpus of the user's hand and adapted to move in concert with movement of the metacarpus relative to the forearm member as the user's wrist moves in yaw between discrete left, right, and central yaw positions,
• a plurality of finger members positioned respectively at the user's fingers and adapted to move in concert with movement of the respective fingers, the finger members further comprising
• a finger proximal member positioned beyond the user's metacarpal joint and adapted to move in concert with movement of the user's proximal finger segment relative to the metacarpus as the user's proximal finger segment moves in pitch,
• a finger distal member positioned beyond the user's proximal joint opposite the finger proximal member and adapted to move in concert with movement of the user's intermediate and distal finger segments relative to the proximal finger segment as the user's finger moves in pitch, the distal member moving between at least two discrete pitch positions, the at least two pitch positions in combination with the yaw positions of the metacarpal therein comprise at least six discrete positions representing six unique data representations, which in combination with five fingers, including a thumb, represents at least thirty unique data representations for each user hand,
• a thumb proximal member positioned beyond the user's thumb metacarpal joint and adapted to move in concert with movement of the user's thumb proximal segment relative to the metacarpus as the user's thumb proximal segment moves,
• a thumb distal member positioned beyond the user's thumb distal joint and adapted to move in concert with movement of the user's thumb distal segment relative to the thumb proximal segment as the user's thumb moves, the thumb proximal member and the thumb distal member moving together between at least two discrete positions, the at least two discrete thumb positions functioning in combination with the yaw positions of the metacarpal member therein comprise at least six discrete positions representing six unique data representations,
• a dichotomous finger switch with active and inactive positions switch connected to each of the finger members and activated by downward movement of the respective finger, the finger switch also connected to a computer processor such that upon downward movement of the respective finger, the position of the respective finger and the wrist is recorded as a unique data entry.
• wherein the metacarpal member is positioned to move in concert with movement of the metacarpus relative to the forearm member as the user's wrist moves in pitch between discrete wrist pitch positions of up, central, and down positions, the wrist pitch positions being independent of the yaw positions in which wrist pitch positions function in combination with the yaw positions therein defining nine discrete metacarpus positions,
• in which the wrist pitch positions and the finger and thumb pitch positions move in combination between at least three combined pitch positions, wherein downward movement of a finger required to activate the respective finger switch is determined by relative movement of the finger proximal member in the finger metacarpal joint and movement of a thumb required to activate the respective finger switch is determined by relative movement of the thumb proximal member in the thumb metacarpal joint,
• a wrist movement switch comprising a base mounted to one and a plate mechanically connected to the other of the forearm member and the metacarpal member, the base having four base electrical contacts equidistant from a base center arrayed in orthogonal disposition, the plate spaced apart from the base and having four plate electrical contacts opposing the four base electrical contacts, the plate mounted on a distal end of a rod, a proximal end of the rod mounted to the other of the forearm member and the metacarpal member such that when the user's wrist moves left, right, up or down, one of said plate electrical contacts moves into contact with one of said base electrical contacts adapted to indicate such movement by which electrical contacts are in contact, if any, and wherein electrical contact between the base and the plate communicates an electrical signal to said computer processor indicating said movement upon said downward movement of a finger actuating said finger switch,
• a finger-thumb pitch switch at the proximal joint of each finger and thumb communicating orientation of the finger members to the computer processor.

The method of a user inputting keyboard keystroke data to a data processor without using a keyboard, comprising the following steps:

• a. Fitting a glove on a hand of the user, the glove having a forearm section, a metacarpal section and finger and thumb sections adapted to fit over the fingers, metacarpus, wrist and forearm of a user, the glove being outfitted with members adapted to track movement of the user's hand, fingers and thumb including a forearm member, a metacarpal member, a plurality of finger members, the forearm member attaching to the glove forearm section, the metacarpal member attaching to the glove metacarpal section, and the finger and thumb members attaching to the glove finger and thumb sections, with a dichotomous finger switch with active and inactive positions mounted to the glove in the glove forearm or metacarpal section, and a wrist movement switch connected between the forearm member in the forearm section and the metacarpal member in the metacarpal section adapted to sense movement of the wrist between discrete positions in yaw and in pitch,
• b. The user adjusting the wrist to a discrete position of the metacarpus in yaw,
• c. The user adjusting the wrist to a discrete position of the metacarpus in pitch,
• d. The user adjusting a selected fingers to a discrete position in pitch, the wrist position in yaw and pitch and the selected finger in its position in pitch uniquely identifying a selective alphanumeric or other symbol, or command,
• e. The user exercising the selected finger in a downward motion by rotating the user's finger downward in the finger's metacarpal joint, therein pulling a tether between the finger distal member and the finger switch to activate the switch, identifying the respective wrist and finger positions in an electronic message to the computer processor, interpreted in the computer processor as said selective alphanumeric or other symbol or command,
• f. Disconnecting said finger switch by lifting said selected finger in an upward motion.
• g. Repeating steps b-f to enter additional selective alphanumeric or other symbols or commands.
