Relatively zooming in, zooming out or rotating, the corresponding execution instructions can be output for the screen content of the screen. [0002] [Prior Art] At present, due to the rapid advancement of electronic information technology, the display screens of various related electronic tweezers devices are gradually transformed into touch screens, and all operations are touched on the screen. The achievement is quite convenient for the user, and the operation mode of the touch screen has been greatly changed with the control method of the conventional screen. For example, the operating system on the computer can even omit the operation of the mouse and the keyboard. For all the simple screen reduction, enlargement and rotation on the screen, you can directly touch on the screen. For example, the Republic of China invented the No. 1296395 announced on May 1, 1997. A method for controlling image enlargement and shrinkage on a control screen, which is a method for switching an image displayed on a touch screen between a first size and a second size, the method comprising The following steps are as follows: (a) displaying the image on the screen in one of the first size or the second size; (b) receiving a signal caused by an external force applied to the touch screen (C) determining, according to the signal, whether the position of the external force applied to the touch screen is in a range relative to the image; and 098123678 (d) if the result of the step (c) is affirmative, Turning off the image displayed on the screen form number A0101, page 3/15 pages 0982040349-0 201102892, and redisplaying the image in the first size and the second size in the touch On the screen. The above-mentioned operation method is that the function of the multi-touch screen generates the function of performing zooming, zooming, and rotating in the screen of the screen by means of the relative relationship of multi-touch on the screen. User-friendly interface. However, the mechanism must detect the application of external force on the screen, so it can only be acted upon by the screen. However, when making a briefing, the movement of the hand or the guiding stick is likely to affect the conventional laser director of the line of sight 4, and the current multi-touch screen cannot be implemented due to no external force. It is customary to use a laser spot to control a mouse mouse, such as the Republic of China Patent Open Publication No. 2007371 16 "A System for Controlling a Computer Mouse Cursor with a Laser Spot", which discloses the use of a video camera sold in the market. The technique of shooting laser light at the display surface and performing digital image processing' (4) shooting the position of the laser spot in the image, and then immediately (4) the electric county rat dragon, the leader can control the tradition of the laser spot The movement of the computer mouse cursor, this will greatly enhance the user's convenience in the briefing. However, the single point of the laser spot can only produce the function of the mouse, and can not further produce more user-friendly zooming and rotating. Multi-touch screen function. [Invention] [0003] In view of the disadvantages of the conventional operation, the present invention provides a method for generating a multi-touch screen function by using a light pattern, which comprises the following steps: A. A light pattern is generated on a screen; B. the light pattern is relatively enlarged, reduced, and rotated on the screen; C. The light pattern is changed: the screen is captured by the screen The glazing pattern is analyzed and the light pattern is enlarged, 098123678 is reduced or rotated; D. is based on the position and change of the light pattern. The output is relative to the form number A0101. Page 4/15 pages 0992040349-0 201102892 Command: Re-determine the coordinate position of the light pattern corresponding to the content of the screen, and output the execution instruction corresponding to the content of the screen. The content of the screen on the screen is a picture, and the light pattern is relatively enlarged, reduced and rotated. The corresponding execution instruction is to enlarge the picture, reduce the picture and rotate the picture. The content of the picture on the above screen is music, the light pattern is relatively enlarged, reduced and rotated, and the corresponding execution instruction is increased [increase 〕 Volume, decrease [decrease] volume and mute [pause] Ο The content of the screen on the above screen is a movie, the light pattern is relatively enlarged, reduced and rotated, and the corresponding execution instructions are image fast rotation and image slow rotation. The light pattern is generated by a laser light. The light pattern is generated by an infrared light. The light pattern is formed by a set of lightning. The present invention has the following advantages: 1. The present invention is capable of directly utilizing the light pattern change emitted by the laser pointer on the screen, and directly on the screen content of the screen, The corresponding execution instruction is operated. 2. The invention is particularly suitable for making presentations, teaching, and playing a movie, which can make up for the shortcomings that the user cannot directly touch and operate the screen, and is quite convenient and simple in operation, and can save.
