Remote control system and its control device

The present invention relates to a remote control system, and more particularly to a remote control system and a control device for remote mouse control using visible light and invisible light simultaneously.

With the rapid development of digital technology and electronic products, people can make various data collation and information presentation in daily life, academic research or workplace more quickly and conveniently with the help of various electronic products. Among them, e-newsletters are the most common. Users can freely edit e-newsletters on electronic devices. Through simple and easy-to-use briefing and typography software, users can set visual effects, add music, sound effects and even video videos in the newsletter. Increase the viewer’s interest and increase the effectiveness of the presentation.

In general, the presentation of the electronic presentation is mostly performed by projecting a pre-made electronic presentation of the electronic presentation stored in the electronic device on the projection screen. To increase the vividness of the briefing, the presenter expects to be able to move freely or unrestrictedly interact with the audience. In view of this, the industry has developed a variety of remote control systems, which aim to remotely control the electronic device by using the control device of the remote control system, so that the presenter can be free from the limitation of the wire, and the electronic device can be directly controlled by only the handheld control device. , such as the operation of the briefing and the text of the briefing.

For example, conventional remote control systems can be divided into three main categories: one through a single mine The light spot is used for position guidance; the second is to use the sensing element to capture the target for mouse control; and the other is to use the shaking sensor and determine the displacement direction and send the relative movement amount to control the mouse coordinate position. However, these remote control systems still have a number of disadvantages. Please refer to FIG. 1 , which is a schematic diagram of position guidance of a control device of a conventional remote control system. As shown in FIG. 1, the control device 11 of the conventional remote control system 1 transmits a single laser spot to the screen 12 as a position guide, and the presenter can transmit the electronic newsletter projected on the screen 12 through the control device 11. The position guidance, however, the control device 11 cannot actually perform the control action. Therefore, when the briefer wants to perform an operation such as turning a page or writing a note, it is still necessary to move to the electronic device to control and operate through the mouse.

Please refer to FIG. 2, which is a schematic diagram of position guidance of a control device of another conventional remote control system. As shown in FIG. 2, the conventional remote control system 1 controls the device 11 to transmit a single laser spot to the screen 12 as a position guide, and the remote control system further senses the spot through the sensing element 13 when the laser spot is used. When the position on the screen 12 is within the sensible range of the sensing element 13, the sensing element 13 captures the coordinate position of the spot for mouse control. However, this method can only perform displacement control on the mouse cursor position, and cannot perform any type of click control function. Therefore, if you want to perform mouse click, drag and drop function or want to share with the virtual electronic whiteboard, you must install two senses. Measuring components, respectively controlling the click action of the mouse and the displacement control of the position of the mouse cursor, not only cause cost increase, but also make the system setup much more difficult.

Please refer to FIG. 3, which is a schematic diagram of shaking of a control device of a conventional remote control system. As shown in FIG. 3, a part of the remote control system on the market is remotely controlled by the control device 11' of the swaying sensor, which mainly transmits the sensing device 11' by shaking, and the swaying feeling inside the control device 11' The detector takes the direction of the displacement, and then sends the amount of movement to the electronic device to control the displacement control of the cursor position of the mouse, but the shift Momentum is a relative value, so it is less intuitive to use and difficult to use.

In combination with the various shortcomings mentioned above, although the conventional remote control system provides a preliminary remote control for briefing, in most cases, the briefer still has to return to the electronic device to use the mouse to control, which is not effectively solved by the wire. The problem is that the quality of the newsletter cannot be improved, and it is easy to cause problems such as interruption of the briefing process.

The main purpose of the present invention is to provide a remote control system and a control device thereof, which can only perform displacement control when a conventional remote control system uses a single sensing component, and must have two sensing components when performing other functional control. The shortcomings of cost and system setup difficulty, and the fact that the user has to return to the electronic device in most cases to control by the mouse and are limited by the wire, can not improve the quality of the briefing and easily cause the interruption of the briefing process.

Another object of the present invention is to provide a remote control system and a control device thereof, wherein the first band light and the second band light are simultaneously emitted by the control device, and position guidance and motion control can be simultaneously performed, thereby being directly unrestricted Manipulate to achieve effective improvement of presentation quality and smooth presentation process.

Another object of the present invention is to provide a remote control system and a control device thereof. Through the design of the second-wavelength light, displacement and other function control can be simultaneously performed without adding a sensing component, and can be shared with the electronic whiteboard to achieve Reduce system cost and installation difficulty.

In order to achieve the above objective, a wider aspect of the present invention provides a remote control system for an electronic device, and is configured to perform position guidance and motion control when the electronic device presents an electronic presentation on a screen through a projection device. The remote control system at least The method includes: a control device that emits a first band of light and selectively emits a second band of light to the screen for position guidance and motion control; and a sensing component coupled to the electronic device, The second band of light is sensed, and a control command is transmitted to the electronic device according to the sensing result.

In order to achieve the above object, another broad aspect of the present invention provides a control device suitable for a remote control system including a sensing component, and the remote control system is configured to be connected to an electronic component connected to the sensing component. The device provides location guidance and motion control when an electronic presentation is presented on a screen through a projection device.
