Method and device for the one-handed input of data
First Claim
1. A device for single handed input of data as coordinates in a multi-axis coordinate system and as alphanumeric symbols and control commands, comprising:
- a stationary lower member for disposal upon a support surface;
a housing mounted above said stationary lower member for transverse pivoting, relative to said lower member, about an axis perpendicular to the support surface extending through a wrist of a user;
an elongated key disposed in an upper part of said housing for data input, said key having a transmitter member for detecting a longitudinal coordinate position of a fingertip of the user on said key, and a converting device disposed within said housing between said elongated key and said stationary lower member to detect and convert said transverse pivoting of said housing and said longitudinal coordinate position of said key into electrical signals as data interface input, wherein conversion of said input motion is effected with a resolution which depends on a mode of operation.

Abstract
The invention concerns a device for the one-handed input of coordinates of multi-axis coordinate systems and alphanumeric characters and control commands, the device being operable with one hand. The forearm does not participate in the movements and rests on a support. The device comprises a plurality of elongated keys having sensor surfaces which, when depressed, detect and evaluate the position of a fingertip as a coordinate. The device comprises a housing which detects and evaluates the ulnar pivot movement of the hand as a horizontal coordinate and the pronation of the hand and a translation in the direction of the arm as control signals. The device combines the input functions of a mouse and a keyboard.

11. A method for single hand input of data using an input device comprising the following steps which can also be carried out in differing sequence:
-
a) choosing differing keyboard assignments for input of coordinates, alphanumeric symbols and control commands;
b) detecting said keyboard assignments;
c) detecting a position of a fingertip on an elongated key relative to a longitudinal extent of said key, wherein said longitudinal extent is in a longitudinal direction of a forearm of a user;
d) detecting a pivot motion at the input device as an ulnar abduction via a pivot angle;
e) at least one of rotating and tilting the input device as a pronation via at least one of a tilt angle and a rotation angle; and
f) detecting said pronation of step e), wherein conversion of input motion is effected with a resolution which depends on a mode of operation. - View Dependent Claims (12, 13, 14)
