Embodiment Construction

[0023] Describe in detail below in conjunction with accompanying drawing.

[0024] figure 1 is a schematic diagram of a reduced-sized keyboard of the prior art. It has been described above. figure 2 It is an embodiment of the keyboard of the present invention that recognizes keys by finger, and shows the layout structure of the two-handed keyboard. The frames of different shapes in the figure represent the actual characters produced when different fingers strike keys. As shown in the figure, the entire input device is divided into a keypad and a finger contact. The function of the keyboard is the same as that of an ordinary keyboard, and the finger contact is used to distinguish the fingers of the keystrokes. Only four fingers have contacts here, because the thumb on the traditional keyboard is only used for the space bar, so the final code can be directly generated for the space bar. The implementation of connecting the keyboard is the same as that of the common keyboard...

Abstract

The finger-identifying keyboard includes several keys; several finger-worn sensors to replace different fingers; and a code synthesizer for synthesizing codes and creating final input code signal. The present invention makes it possible to decrease effectively the number of keys in a keyboard and decrease the size of keyboard for the needs of different hand-held equipment.

Description

technical field [0001] The present invention relates to a keyboard for recognition by finger-stroke, more specifically, to a keyboard for recognition by finger-stroke which can reduce the number of keys and the size of the keyboard. Background technique [0002] Data input is an essential function of various electronic devices, among a large number of current input methods, keyboard input is still in the leading position in terms of speed and accuracy. As electronic devices continue to be miniaturized, input devices are also shrinking in size. [0003] In the prior art, the miniaturization of the keyboard has certain limitations. First of all, in order to enable the user to conveniently input with fingers, the size of the keys should not be too small. If the keys are too small, they cannot be operated with fingers, or they are prone to misoperation. Secondly, in order to be able to input enough numbers and alphabetic characters, it is necessary to ensure that the keyboard ...
