Computer Mouse Price in Bangladesh

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface (plural mice, seldom mice). This motion is usually translated into the movement of a pointer on a display, allowing for smooth control of a computer's graphical user interface.

In 1968, a mouse was used to manipulate a computer system for the first time in public. Mice are used to track movement across a surface with two distinct wheels, one in the X-dimension and one in the Y-dimension. Later, the typical design moved to detect motion with a ball rolling on a surface. Optical sensors, which have no moving parts, are used in the majority of modern mice. Though all mice used to be wired to a computer, some current mice are wireless and rely on short-range radio communication with the linked system.

Computer mice feature one or more buttons in addition to the pointer to allow activities such as selecting a menu item on a display. Other features, such as touch surfaces and scroll wheels, are frequently seen on mice, allowing for more control and dimensional input. Early optical mice relied solely on one or more light-emitting diodes (LEDs) and an imaging array of photodiodes to detect movement relative to the underlying surface, avoiding the internal moving elements that a mechanical mouse relies on in addition to its optics. An optical mouse that uses coherent (laser) light is known as a laser mouse.

Optical mouse:

The first optical mice recognized movement on pre-printed mousepad surfaces, whereas the present LED optical mouse can detect movement on most opaque diffuse surfaces, but not on specular surfaces like polished stone. Laser diodes improve performance on opaque specular surfaces by providing high resolution and precision laser, more surface-independent optical mice employ an optoelectronic sensor (basically, a tiny low-resolution video camera) to take several images of the surface on which they work. Wireless optical mice that are powered by batteries flash the LED intermittently to conserve power and only glow steadily when movement is detected.

Mouse for gaming:

These mice have been created specifically for use in computer games. They usually include a larger number of controls and buttons, as well as designs that are very different from ordinary mice. They could also have programmable RGB LED lighting or ornamental monochromatic lighting. The extra buttons are frequently used to change the mouse's sensitivity, or they can be allocated (programmed) to macros (i.e., for opening a program or for use instead of a key combination). Game mouse, particularly those developed for use in real-time strategy games like StarCraft or multiplayer online battle arena games like Dota 2, are known for having a relatively high sensitivity, measured in dots per inch (DPI), which can be as high as 25,600. Some modern gaming mice allow users to modify the weight of the mouse by adding or deleting weights, allowing for more precise control. Extended gameplay periods may make subsequent usage of the mouse uncomfortable, hence ergonomic quality is particularly vital in gaming mice. Adjustable features on certain mice include removable and/or extendable palm rests, horizontally adjustable thumb rests, and pinky rests. To ensure comfort for a wider range of target users, some mouse may supply multiple different rests with their devices. Gamers hold gaming mouse in three different ways.
