Simulation keyboard utilizing finger forms as keys

Abstract

The invention discloses a simulation keyboard for man-machine interaction of a computer, a cell phone or other digital equipment. Used key orders are set into a plane-array layout form. Various keys are expressed or pre-defined by suspension and touch, extension, contraction, and a combination of original states (namely, hand shapes) of fingers. Extension, contraction and touch states of all fingers of an operator, or detection of touch types (extension touch, contraction touch, and original state touch) of all fingers are detected, and the detection value is matched with hand shape codes so as to identify the key orders to be input, and therefore the function of a keyboard is realized. When the number of keys is large, the keys are classified according to modes (setting the hand shapes to conduct shift of various modes) so as to enable the same hand shape to stand for different keys in different modes; or a key array is spread in lines or rows so that the same touch stands for keys in different lines or rows. A sensor is arranged on a mouse, or a mouse detection component is arranged on hand so as to realize integration of the simulation keyboard and the mouse.

Description

Technical field [0001] The utility model relates to a human-computer interaction device for computers, mobile phones and other digital devices, which is characterized in that the keys are represented by the combination of the operator's finger stretching, retracting and touching objects around him, and the corresponding keys are generated through finger shape detection. Value, realize keyboard function without keyboard. Background technique [0002] At present, the keyboards of known digital devices (computers, mobile phones, numerical control systems, and other intelligent terminals, etc.) are generally arranged on a surface (usually a plane) by a plurality of keys according to a certain arrangement rule, and the bottom is generally in one-to-one correspondence with the keys. The detection keyboard touches the sensor array and the driving circuit, and uses the frame to consolidate all the buttons, the sensor array and the driving circuit into one body to form a physical key...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing keyboard input that the hands cannot leave the keyboard and the fingers are required to position and touch the keys, the present invention provides an input system that only needs to use fingers to simulate the touch action on the keys of the keyboard, and use sensors to detect the shape of the fingers , the corresponding key value can be generated by processing the finger shape information through the microprocessor, and the key input operation of the keyboard can be realized
