Description

Virtual projection pen

The present invention relates to a virtual projection pen, especially a virtual projection pen that can create virtual light spots, change the color of the virtual light spots, record movement tracks, capture screen images, and upload captured images to the cloud.

Nowadays, the application of LCD is becoming more and more popular, and the price of large-size displays on the market has also decreased. The contrast and color of LCD are better than those of projectors on the screen. Therefore, many educational institutions and enterprises have used electronic The way that billboards replace projection, despite these advantages, still faces some challenges in use, especially when the laser pen is projected on the LCD screen, part of the laser spot will be absorbed, causing the laser light source to decrease or even It may disappear, so that the audience in the audience cannot know the key points of the speaker.

In addition, the current technology is developed based on the computer platform, and the cursor of the mouse is often used as the light spot of the laser projection pen. This will face the following problems in use: 1. The same screen, the screen There will only be a light spot or a cursor display; 2. It cannot be plug and play and can only be used on a specific device; 3. You need to install a driver on the computer to move the mouse cursor remotely, software It should be highly dependent; and 4. Shortcomings such as inability to change the color and size of the light spot in time.

Also known projection pens, such as the Republic of China M545944 new patent "Presentation Device and Presentation System", which reveals a presentation device for users to operate the presentation device with one hand to perform keyboard typing and mouse click functions And the present invention also proposes a presentation system for the user to execute keyboard typing and mouse click functions on the execution device, and when the keyboard function is executed, the user can get the corresponding keyboard function prompt.

Another example is the Republic of China Patent No. I531933 "Presentation System", which discloses a presentation system that detects the position of a control element emitting an infrared ray to a sensing surface of an infrared receiving unit to control the display in a display plane Of a cursor. In addition, the speaker can also control the cursor to produce a special effect on the display plane by operating the control element. However, the aforementioned M545944 patent has the disadvantage that it needs to be connected to a computer and requires an external light-emitting device, which is less suitable for liquid crystal displays. In addition, the I531933 patent is to use a remote infrared device to control the cursor of the computer, treating the cursor as The light spot of the laser pen needs to rely on the software and hardware devices on the computer to produce the shortcomings of the cursor, which is a flaw in the United States.

In view of the above-mentioned shortcomings of the conventional projection pen, the present invention provides a virtual projection pen to improve the above-mentioned shortcomings.

One purpose of the present invention is to provide a virtual projection pen which can produce virtual light spots.
