Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Fig. 1 includes the main components and parts of the present invention: beam pen, light shielding medium, photosensitive element, microprocessor and related circuits, signal output line. The beam source adopts green LED with sufficient brightness and appropriate wavelength. Usually the distance between the beam pen and the keyboard is about 50cm. The size of the light spot is about the size of the receiving surface of the photosensitive element. The collimation and focusing of the light beam can be obtained by adding a focusing lens in front of the LED, or by using an RCLED with its own resonant cavity.

[0023] The light transmittance of the light-shielding medium is about one thousandth. A material with an appropriate thickness and a refractive index corresponding to the light beam is sufficient.

[0024] The photosensitive element can be a photosensitive ...

Abstract

The invention discloses computer information input device and method, which avoids the limb damage and germ propagation of normal keyboard and mouse and simplifies the input of three-dimension spatial movement information. The device contains a hand-held light beam pen and corresponding light signal receiver with some light sensitive elements on the surface, wherein the receiver microprocessor analyses the position and pattern of light beam movement and outputs the corresponding signal.

Description

technical field [0001] The present invention relates to an apparatus and method for inputting information to a computer using light beams, and more particularly, the present invention relates to computer keyboards, mice, and methods of use using light beams. Background technique [0002] At present, commonly used computer keyboards and mice all require users to place their hands on a fixed plane, keep their bodies in a fixed posture, and tap or press the keys with their fingers. Long-term use of the keyboard and mouse will cause injuries and pains to the user's wrist and scapula, such as tenosynovitis, carpal tunnel syndrome, frozen shoulder and other diseases common to computer workers. For upper limbs, there are injuries or disabled people, and the button-type keyboard and mouse are even more inconvenient. The keyboard that fingers touch all the time is also a hotbed of bacteria and a vector of transmission of various infectious diseases. [0003] On the other hand, ther...
