Laser is a Light Amplification by Stimulated Emission of Radiation (LASER). In general, lasers are used to selectively amplify light bands with good response characteristics. There is a trend.

A mouse is a peripheral device used to use a cursor displayed on a monitor of a computer, and a mouse is the most common user input device used in a computer operation. Since the mouse was invented by Douglas Angelbart of the Stanford Research Center in 1963, the mouse has not only moved cursors, but also icons, buttons, and menus displayed on the monitor. It can also be used to run a program by clicking), etc., and to select specific text. The mouse can be divided into ball mouse, pen mouse, optical mouse, and coil mouse according to its shape and principle of operation, and serial mouse, PS / 2 mouse, USB mouse, and bus mouse. With the advent of point-click systems such as the Windows system, mice are now more important than or more important than keyboards and are often used by users. It is recognized as a standard device.

Recently, a mouse, a wireless mouse, a vibrating mouse, etc., with a scroll wheel, have been introduced, and technology has been developed in a direction to increase user convenience.

In order to make a presentation, the control signal is received by the laser pointer 1 and is input to the computer 2 through an input port.

Therefore, while pointing the screen with the laser pointer and providing supplementary explanation, when the screen switching is necessary, laser beam is emitted to the laser receiver to control the switching of the presentation screen.

The receiver 6 has a mouse output terminal for receiving a mouse control signal from the computer 2 and a mouse output for outputting the mouse control signal to an input port (not shown) of the computer 2. A terminal, a laser receiver 6 receiving the control signal of the laser pointer 1, an amplifier (Fig. 4) for amplifying the received signal inside the laser receiver, and decoding the amplified signal. A relay switch 8 for receiving a decoder, the decoded signal and outputting a control signal, and a computer 2 for selectively outputting a signal of the relay switch and a signal input through the mouse input terminal through the mouse output terminal. It consists of a laser receiver (6) to control the input to.

That is, when scanning the optical sensor 7 of the laser receiver without scanning the screen 4 with the laser pointer, a potential difference occurs due to a change in the amount of light (see FIG. 4 circuit), and the relay switch is used by using the potential difference.

The top sensor shown) generates a potential difference in response to the red color of the laser, which is then amplified by the op amp and directed through the red LED. 9 is a flowchart in which each color of the color sensor reacts.

The laser receiver may be configured by using a color sensor that recognizes only the red color of the laser pointer using the above principle.

In addition, since the laser sensor does not show a potential difference in the amount of external light and reacts specifically to the laser wave, the laser sensor can be selectively used in the optical sensor unit.

Since the optical sensor is not specially manufactured and generally has a small diameter of the lens 20 in its outer shape, it is difficult to receive the light of the laser pointer.

In order to compensate for the above disadvantages, the convex lens, the concave lens, and the prism are selectively combined on the entire surface of the optical sensor lens 20 to form an optical lens unit for condensing light, or a parabolic antenna called a dish antenna.
