Description

Laser mouse pen

Technical field

The invention relates to a computer aided input device, in particular to a laser mouse pen. Background technique

At present, optical mouse has gradually become the mainstream of the mouse market. The current optical mouse is still dominated by the traditional mouse shape, and its use can never be used flexibly like a pen. When the mouse is used for a long time, the hand and shoulder are extremely vulnerable, and the "mouse hand" has become a common symptom of computer users.

The applicant applied for the Chinese utility model patent No. 200420094135.0 entitled "Photoelectric Mouse" changed to a pen-shaped shape for the user to hold and slide control, writing and drawing. In order to adapt to the normal pen angle of the user, a diagonal slit is arranged at the bottom end of the pen head, and the oblique slit slides on the sliding plane, and the light is irradiated on the sliding plane through the oblique slit. However, this type of photoelectric pen mouse still uses the ordinary light-emitting diode as the light source like the traditional optical mouse. Since the effective distance of the light emitted by the ordinary light-emitting diode is very short, it is necessary to ensure that the oblique cut is closely attached to the sliding plane when used. Moreover, in order to satisfy different pen-holding angles, the pen tip needs to be designed to be pivotally connected to the pen holder, which is inconvenient in manufacturing and use; in addition, the environmental requirements of the optical mouse using ordinary light-emitting diodes Higher, for example: On a glass tabletop, because the glass surface is smoother, the particles are too small, and the light emitted by the LEDs has a short wavelength, making the photoelectric pen mouse impossible to use on the glass plane.

At the end of 2004, a laser mouse with a laser as a light source was introduced. Since the laser beam is irradiated on the sliding plane, interference fringes can be formed, so that the spot can be received by the receiving sensor, and the image formed by the laser irradiation is more precise and can be slid. The small particles of the plane are presented to the receiving sensor, which can adapt to various sliding planes. It is foreseeable that laser mouse instead of optical mouse has been the development trend of the mouse industry. However, existing mice that use lasers as a light source still use tradition. The mouse shape is never as flexible as a pen.

In addition, as a computer-aided input device, the existing mouse can not achieve the convenience of handwriting input like a pen, and it is more difficult to control the operation direction of the stroke, and the existing handwriting input devices on the market are limited to the handwriting input board provided by the manufacturer. Handwriting input on. The strokes generated at each point on the tablet need to be directly reflected in the computer. This method is reflected in absolute data. If it is separated from the tablet, it is completely unusable. Therefore, in order to reach every point on the tablet. The location reflects its tactile function, and the production cost of the tablet and its mechanism is very expensive.

In order to achieve the purpose of handwriting input using the mouse, the applicant has also applied for application number 99234963.X (named "Pen Mouse"), 01246861.4 (named "Optical Pen Mouse"), 200420094135.0 ("photoelectric mouse") and other patents. Since the application of the photoelectric pen mouse in 2004, the development of the mouse handwriting input software has been considered, but since the contact surface of the mouse is completely different from the input mode of the tablet, the cursor movement of the mouse is based on the user's movement speed. A new relative-displacement-based software must be developed in synchronization with the relative data on the computer screen to work with mouse handwriting input. The mouse has a limitation on the handwriting input board, which greatly reduces the production cost and adds a handwriting input function to the mouse. However, the control buttons of the existing pen mouse that can be written must use the left button, and the buttons used are all the system buttons. Whenever the force is pressed, there will be a large delay stroke difference, which is inevitably handwritten. When inputting, it requires a large force to press, the use time is a little longer, the hand is easy to fatigue, the holding difficulty is difficult, and the writing difficulty is increased. At present, the standard button click life of the mouse is about 500,000 times. For writing, a slightly longer article may reach tens of thousands of words, and each word is composed of several strokes, which makes writing such an article. It may be necessary to use one or even more than one mouse, and the cost of use is too high. Summary of the invention
