We all know that the traditional mouse can only move up, down, left, and right, and when we are playing games, such as CS games, which are not familiar to everyone, because the movement of the gun, shooting and other operations use the mouse lying on the desktop The movement and click are realized, but the real scene is not like this. Compared with the traditional mouse, the 3D mouse has six movement directions of front, back, left, right, up and down, and can combine the movement directions of front right, bottom left and so on. The appearance is different from the ordinary mouse, generally consists of a fan-shaped base and a movable controller. In addition, it has a vibration function, that is, a tactile feedback function. When playing certain games, when you are hit by an enemy, you will feel your mouse vibrate. The 3D mouse consists of 3 parts, a power supply, a microprocessor, and an acceleration sensor. The acceleration plays a "3D" role, and the acceleration sensor is an electronic device capable of measuring acceleration force. Acceleration force is the force when an object acts on an object during acceleration, just like the gravity of the earth, that is, gravity. The acceleration force can be a constant, such as g, or a variable. There are two types of accelerometers: one is the angular accelerometer, which is improved by the gyroscope (angular velocity sensor). The other is the linear accelerometer. When the accuracy of the acceleration sensor is very high, we can use it to measure the displacement on the mouse. The accelerated sensor CMR3100 launched by world-class accelerated manufacturer VTI is widely used in various consumer electronics products because of its low power consumption, high accuracy, and small size. VTI's CMR3100 three-axis angular velocity gyroscope measures only 3.0x3.0x0.88mm3, can integrate any mobile device, and provides a more advanced user interface experience for battery-powered mobile devices. In addition to the more compact size, ultra-low power consumption is also a weapon to surpass other similar products. The CMR3100 only requires 2.5mA current drive, which greatly improves battery life. At such low power consumption, the CMR3100 can provide full digital gyroscope functions, including four measurement ranges and user-selectable signal bandwidth with high-pass filtering.
