specific Embodiment approach

[0013] Attached below figure 1 Describe the specific implementation method: a handwriting tablet that uses image recognition technology for computer input, consisting of a panel 1, a base 2, a horizontal light emitter 3, a horizontal light receptor 4, a vertical light emitter 5, and a vertical light receptor 6. Its characteristics yes:

[0014] The panel 1 and the base 2 are fixed together.

[0015] Described transverse light emitter 3, transverse light receptor 4, longitudinal light emitter 5, longitudinal light receptor 6 are fixed together with panel 1, and can be connected with computer by data line, and the light emitted by transverse light emitter 3 can be The corresponding horizontal light receptors 4 feel the light emitted by the vertical light emitters 5 and can be sensed by the corresponding vertical light receptors 6 .

[0016] The following is a specific example to illustrate an input method of a light positioning type tablet:

[0017] In general, since there is...

Abstract

The invention provides a light positioning handwriting board which comprises a panel, a base, a horizontal light emitter, a horizontal light senor, a longitudinal light emitter and a longitudinal light sensor, and is characterized in that the light emitted by the horizontal light emitter can be sensed by the corresponding horizontal light sensor and the light emitted by the longitudinal light emitter can be sensed by the corresponding longitudinal light sensor; the main functions of the light positioning handwriting board are to position the location of a writing tool on the panel through the on and the off of the light, input corresponding X and Y coordinates into a computer, and reflect a track that a user draws on the handwriting board on the screen of the computer; any common object, common pen and finger can serve as the writing tool, the stroke thickness is judged according to the actual contact area between the writing tool and the panel, special button functions or operation can be defined according to the special writing tracks, so that the appearance is simpler, more aesthetic and more generous.

Description

Technical field: [0001] The invention relates to the field of computer peripheral equipment, in particular to a light positioning type handwriting board. Its main function is to use the light on and off to locate the position of the writing tool on the panel, then input the corresponding X and Y coordinates into the computer, and reflect the trajectory drawn by the user on the handwriting board on the computer screen. Ordinary objects, ordinary pens, and fingers can all be used as writing tools, which can define specific key functions or operations based on specific writing tracks, and can determine the thickness of strokes based on the actual contact area between the writing tool and the panel. Background technique: [0002] At present, the handwriting board is one of the very important input devices used for information entry. It occupies a very important position in our life today. The current handwriting board technology is very mature. From the technical principle, it c...
