mickey is measurement unit of speed Of computer mouse.
no
The mouse or the touch-pad controls the cursor.
no. sensors are used to identify movement
Englebert's prototype mouse in 1963 had a wooden shell for the mouse's exterior. It used a PCB and two perpendicular metal wheels to detect direction of movement.
Optical mouse: Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse's movement.
Your player 'turning' movement is bound to your computer mouse. To spin, simply circle your mouse around your character.
An optical mouse is a computer input device that uses a laser to sense the movement of your hand. The old style mouse used a ball with wheel sensors attached to it.
Different CPUs communicate in different ways. Intel processors (Pentiums, Core2, etc) communicate to the chipset using the Front Side Bus. AMD processors communicate to the chipset using Hyper Transport.
The mouse has sensors inside to know which way you moved it. The way this works depends on the type of mouse. In the more traditional optical-mechanical mice, the wheel turns rollers on two axes. Those rollers have slitted wheels, and light shines through the slits to photocells on the other side. Then the photocells send the signal to the mouse's board and then to the computer. From there, the mouse driver converts the signals into cursor movement. In optical mice, there is a laser LED and a digital camera chip. The mouse acts like a video camera, and the circuitry on the mouse's board detects the direction and amount of movement and sends it to the computer. The signals are pretty much the same as with the other type of mouse.
There are various computer mice types based on technology and working principle : ball mouse, optical (LED) mouse, laser mouse. Also they can be categorized based on DPI resolution. Also there are general purpose mouse types and special gaming mouse with lots of customizable buttons and high and variable resolution and faster sampling. Also they can be classified in terms of connectivity to the computer like wired (PS2, USB) and wireless (RF, IR, Bluetooth). - Neeraj Sharma
