More specifically, the present invention relates to an apparatus and method for tracking a position of a light director to emulate a remote control device. [Prior Art] The ❹ ❹ light indexer is a device that projects a light beam onto a surface area to emphasize an item of interest. In many occasions where presentations are displayed on the screen, such as in conferences, lectures, seminars or other occasions, optical indicators have become a common tool. The general speech data is projected from the computer to the display screen using a projection device connected to the computer, such as a liquid crystal projector. In the speech of the rich, the speaker can generate a spot visible to the viewer at any time. A light pointer is used to pull the viewer's endurance to a specific position or target on the display screen. The common light indicator is a hand-held pen type device with a battery circuit, (4) module and lens group. The money module includes a light: / Light source or LED (Light Emitting Diode, LED) = long to emit a given wavelength of light, such as corresponding to red, green or blue light : =: It can contain a switch or press - to activate the remote control. The function of the +4 month is 0. For example, i shows a kind of light #^要开2006/0197756, the finger of the brain, the two θ, the top There are switches to remotely start various electric operations, such as mouse, trackpad and trackball, move, click the left button, right click and double click to press 200933452. The light director emits a beam of light to the image that is projected onto the display screen to produce - the visible spot overlaps the image. This spot is used as a control cursor for the speech computer. In the image processor, a camera is connected to the speech computer for scanning the image projected on the screen. The image processor then analyzes the scanned image to confirm that the control cursor 2 sent by the light director is set to the position of the spot. The user can direct the control cursor to a position in the screen and emulate the position-dependent computer command by means of a switch. The beta light indicator can also contain a controller and a wireless module to send control signals to the speech computer. For example, U.S. Patent Publication No. 2〇〇6/〇2271〇7 discloses a light index H having a wireless operation module for transmitting a control signal to a speech computer 'this action means that the light indicator is pressed. Set the switch. One of the switches may be used to send a "previous page" signal to the computer, and the other switch may be used to send a "next page" signal to the computer. The “Previous Page” and “Next Page” §fl numbers will instruct the computer to display a new speech page and project it onto the screen. The light indicator can also be integrated with other devices. A light indicator can be integrated into a wireless mouse as disclosed in U.S. Patent Publication No. M17,840. This versatile device can optionally be used as a mouse to communicate with the computer for control signals and as a light indicator to send a beam of light onto the projection screen. In addition, the optical indicator can be modified to produce a modular output (instruction) as a control signal for the projection system. U.S. Patent Publication No. 2007_30460 discloses an optical indicator having a modular output (unit) for providing commands to a projection system. The projection system has a 4 200933452 integrated image sensor to detect the position of the light spot sent by its light indicator. In one example, the (4) person can press the pulse on the target device to emit a pulse of a specific frequency. This pulse indicates that the projection system monitors the position of its light indicator as a result of the mouse "drag" until the user presses the button again to stop the brewing. These existing light indicators use mechanical buttons or switches and can only be used as remote controllers. The user must manually manipulate these switches to control the speaking computer. This is not only troublesome, but also practically difficult, because in addition to giving a speech, the user must distract attention to control these switches. These switches are also prone to errors or failures during the entire speech. Therefore, we would like to provide a light indicator device that can simulate a remote control device (such as a wireless mouse) without the need for a manual switch. In particular, it is desirable to provide an optical indicator device and method that can be used to track the position of the light and use the position to control the speech computer. [Invention] Φ The present invention discloses an optical indicator device.
