Pointer mouse with writing function

Abstract

The invention discloses a pointer-shaped mouse capable of realizing writing on a projection screen. A speaker usually adopts a power point (PPT) displayed by a computer to make a presentation. A turner spread in the present market only can finish simple page turning action, but cannot realize positioning and selection functions like a computer mouse. Simultaneously, the speaker is often required to perform blackboard-writing, and even though conventional computer software such as OneNote supports handwriting input, how to directly perform electronic writing on the large projection screen is undoubtedly a problem to be solved. The pointer-shaped mouse capable of realizing writing on the projection screen can realize the mouse pointer positioning, menu selection and direct drawing and writing on the projection screen.

Description

[0001] Technical field: This patent belongs to the field of computer IT. Background technique:

[0002] The speaker usually uses the PPT played by the computer when making a presentation. The popular page turners on the market can only complete simple page turning actions, but cannot realize the positioning and selection functions like a computer mouse. At the same time, the speaker often needs to do some writing on the blackboard. Although computer software (such as Microsoft OneNote) has supported handwriting input at present, how to carry out direct electronic writing on the large projection screen is undoubtedly still a problem to be solved. Invention content:

[0003] This patent designs a pointer-shaped mouse that can write on a projection screen, which can realize mouse pointer positioning on the projection screen, menu selection, and direct drawing and writing on the screen. detailed description:

Embodiment Construction

[0004] The pointer-shaped mouse designed by this patent has the appearance 3 of a traditional pointer, and the inside includes signal acquisition optical fiber 1, outgoing light guide fiber 2, graphic analysis chip 5 and light source 6 and other main components. There are left and right buttons of a traditional mouse. The working principle of the mouse is similar to that of a traditional photoelectric mouse. The light emitted by the light source 6 is projected onto the projection screen through the outgoing optical fiber, and the light reflected by the screen is transmitted to the image analysis chip 5 by the signal acquisition optical fiber 1. By comparing the two consecutive reflected pictures , the graphic analysis chip can give the moving direction and distance of the pointer. The pointer can slide on the projection screen like a mouse, and can select menus. At the same time, with the corresponding software, the pointer mouse can directly write on the projection screen (li...
