The idea of creating a device to control operation of the computer, which we now call a mouse, belongs to the American scientist Doug Engelbart (born in 1925). In the mid-60s of the 20th century. He designed a device, and the first demonstration of the robot arm was held in 1968

computer mouse - a small box with several buttons. The main ones are the left and right buttons.

There are the following types of computer mouse: Mechanical Optical Laser Trackball Induction Hydroscopically Sensory

A mechanical mouse is a computer mouse that uses a rubber coated metal ball to determine the movement of the mouse. The main problem of a mechanical mouse is its pollution. Dust and other small particles, getting on the ball, accumulate on the coordinate rollers, which prevents their rotation (jamming the ball). Therefore, a mechanical mouse requires periodic cleaning of the ball and rollers. To date, mechanical mice are almost completely replaced by optical mice. MECHANICAL MOUSE

OPTICAL MOUSE An optical mouse is a computer mouse that has a built-in high-speed video camera that takes pictures of the surface with great speed and compares them with the previous ones, calculates the change in mouse position. A special LED or laser surface illumination (usually red) facilitates the work of the camera. Optical mice do not require a special rug and can work on almost all surfaces except transparent or mirror (for example, a glass table).

LASER MOUSE A laser mouse is a kind of optical mouse that uses a semiconductor laser to detect the movement of a computer mouse. Such a laser does not emit a visible glow of the sensor, which does not distract the user from working with it. The advantage of a laser mouse from others is that it: Works on any surface Much more accurate and faster than others Has higher reliability and resolution Has low power consumption

TRACKBALL MOUSE A trackball is an input device that contains a protruding ball. There are usually one or two buttons provided with a trackball. Unlike other input devices which needs movement like the mouse, a trackball is stationary and does not require much space. It can also work on most of the surfaces.

INDUCTION MOUSE An induction mouse is a computer mouse that works by induction energy. Such mice use a special rug, which is necessary for their work, which works on the principle of a graphic tablet or is included in its kit. Induction mice are very precise and do not need a proper orientation. The mouse can be wireless (only a tablet is plugged in) and have inductive power, then the mouse does not require batteries, just like conventional wireless mice.

SENSORY MOUSE In the family of sensory devices came the addition. This device is a touch mouse from the company "Manhattan Products". It should be noted that the unique mouse does not have the usual buttons and even the scroll wheel. In addition, the device is wireless, powered by two AAA batteries, as the developer assures there is an automatic power- saving mode. Touchscreens easily fit into mobile phones and other devices. But whether the new mouse will fit into these devices, we will see in the near future. Surely at first the mouse will not have an "army" of fans, but eventually gain its admirers. The mouse is controlled by touch, rather than the usual clicks.
