Abstract
Abstract A keyboard unit with several ergonomically arranged keys, the keyboard unit consisting partly of a knob having an upper surface suitably shaped for the support of the inside hollow palm of the guiding hand, the knob having a frontal surface with a row of keys ergonomically operational by the fingers of the hand, and on an inside surface a minimum of one key to be actuated by the thumb, the knob being mobile in two coordinate directions, that is, in the longitudinal direction of the arm and perpendicular to it, covering an entire area of input positions, giving the final choice to the finger selection of the proper key for the intended input.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A keyboard unit equipped with a number of ergonomically arranged input keys to operate at least one processor unit operationally connected with said keyboard unit, the keyboard unit having a fixed lower part and a knob-shaped upper part that is adapted to fit into an operator's hand, the knob being movable in two directions perpendicular to one another relative to the fixed lower part, said knob having a front surface with an ergonomically curved row of input keys arranged in a group so as to be actuatable by finger relative to the fixed lower part, and a lateral surface with at least one side input key arranged so as to be actuatable by a thumb relative to the fixed lower part, the fixed lower part comprising a key input field divided into partial input fields and steps in the two directions, each input field having several limited input positions, each of said input keys being arrangeable into several different of said input positions by moving said knob in the two directions.
Claim 2
Dependent Claim
171 words
A keyboard unit equipped with a number of ergonomically arranged input keys to operate at least one processor unit operationally connected with said keyboard unit, the keyboard unit having a fixed lower part and a knob-shaped upper part that is adapted to fit into an operator's hand, the knob being movable in two directions perpendicular to one another relative to the fixed lower part, said knob having a front surface with an ergonomically curved row of input keys arranged in a group so as to be actuatable by finger relative to the fixed lower part, and a lateral surface with at least one side input key arranged so as to be actuatable by a thumb relative to the fixed lower part, the fixed lower part comprising a key input field divided into partial input fields and steps in the two directions, each input field having several limited input positions, each of said input keys being arrangeable into several different of said input positions by moving said knob in the two directions.
Claim 3
Dependent Claim
35 words
A keyboard unit as claimed in claim 1, having integrated a second group of keys in a parallel step in the knob and having a second key located with the at least one side key.
Claim 4
Dependent Claim
53 words
The keyboard unit as claimed in claim 1 wherein the movable knob-shaped upper part is movably connected to the lower part so as to form a single unit that is positionable into a processing system on any level, distance and inclination in relation to the system and to an operator of the system.
Claim 5
Dependent Claim
37 words
The keyboard unit as claimed by claim 1, and further comprising means for receiving an input signal from any of said input positions the keyboard knob commands at any moment resulting from the movement of the knob.
Claim 6
Dependent Claim
41 words
Keyboard unit as claimed by claim 4, and further comprising means for the transformation of every signal, obtained by an actual step position of the knob and activated through a singular position of any of the keys into a digital signal.
Claim 7
Dependent Claim
17 words
The keyboard unit as claimed in claim 4, wherein said receiving means electro-optically receives the input signal.
Claim 8
Dependent Claim
17 words
The keyboard unit as claimed in claim 4, wherein said receiving means electro-magnetically receives the input signal.
