Description of the invention: [Technical field to which the invention pertains] 'The present invention relates to an input device for a shooting game and an input method thereof, in particular to sensing a limb signal by an inertial sensing module to control an aiming point The purpose of the input device for a shooting game of any type of display and its sensing method. • [Prior Art] The light gun is a kind of computer game peripheral device that has appeared in the 8-bit era. The operation mode when shooting with a light gun is similar to the real action of a real gun test. Therefore, such products have been all the rage. The principle of the light gun coordinate imaging is as follows. The conventional scanning television display is composed of a plurality of scanning line signals. Basically, each side signal has 512 scanning lines, and can be transmitted every second. 30 photos®, that is, the frequency transmitted by the TV station is 512x30/sec. As shown in Figure 1, the scan line L is sent horizontally from left to right by the TV electronics. Since the TV screen has a fluorescent material, when After the electronic rushing signal is hit on the screen S, the fluorescent material is illuminated by the radiation and thus emits light. With this characteristic, a light having a specific frequency (that is, the frequency of the television scanning line L) is set in the light ray G. The sensor D and a timer T, when the light grabs G to aim at the target point A on the screen S and presses the trigger, the host C that controls the light gun G sends a signal to the screen S, and the timer T starts counting. When the scanning line L scans to the target point A, a signal can be sent to transmit the light 5 • 1926202 u The grab G is received by the sensor D, and the timer T can calculate the coordinates according to the received trusted time. • In addition to patents related to light ray, generally the Republic of China patents focus on improvements in light smashing or circuit design, such as the Republic of China Patent Application No. 90106273 "Wireless Light Gun", Application No. 86120085 "Shooting "Television Musical Instrument", Application No. 85302961 "Lighting for Game Machines (1)", etc., while foreign patents, most of them should be in the target shooting game and shooting simulation training device, such as US patent US5. 898421 "Gyroscopic pointer and method", which proposes a directional method for operating a moving object in a display. The patent uses a gyroscope to detect the rotational motion of the hand in the space, and displays the angular velocity of the sensing as a cursor of the screen cursor. However, due to the high price limit of the gyroscope, it lacks product competitiveness. In addition, in the US patent US6545661 "Gyroscopic pointer and method", the device for detecting the inclination of the user when aiming by the accelerometer is first proposed to control the aiming point and Method, however, the method of controlling the punctual point in a tilted manner and the actual smashing aiming position are still A certain degree of difference has caused poor control of the aiming point. According to the principle of the above-mentioned light ray imaging, the conventional light gun can only be used on the scanning type display, and the above-mentioned various patents related to the light guns at home and abroad have failed to break through the nest that must be applied to the scanning display. With the evolution of technology, traditional sight-view TVs or monitors are gradually being phased out, and instead of liquid crystal, plasma and rear-projection displays, traditional light guns cannot be applied to the new generation of liquid crystals due to poor imaging principles. In addition, due to the low degree of integration, it is necessary to install additional peripheral devices when using conventional light, which is not convenient to use. In terms of imaging effect, 6 1296202, traditional light robbing When the shot is fired, a white frame (white flash from the control software) is output, which may cause the eyes of the person to fatigue and damage the vision.
