What is a mouse- computer mouse

A Computer Mouse is a handheld hardware input device that a computer user pushes across a desk surface in order to point to a place on a display screen and to select one or more actions to take from that position and can move and select text, icons, files, and folders on your computer. Today, the mouse is an integral part of the graphical user interface (GUI) of any personal computer.

What Are The Parts Of A Mouse?

The standard layout is a left click, right click, and middle click. Most pointer devices also have a scroll wheel, which doubles as that middle click button on most mice. Ball, Laser, LED, image sensor; each of these is used to track the movement by various methods.

Types Of Mouse

There are three types of mouse:

+  Trackball Mouse

+  Optical Mouse

+  Wireless Optical Mouse

+  Trackball Mouse

Computer Track Ball- Computer Fundamental- mLand India Technologies

It is essentially a different kind of computer mouse. It is a plastic case containing a ball on the top that moves a computer cursor around on the screen. The user can move the ball with their thumb or fingers, and sensors inside the case detect which direction the ball is moving. Large trackballs are common on CAD workstations for easy precision.

Is A Trackball Better Than A Mouse?
 
It does take a bit of a time to get used to the motion especially when you are trying to track fairly straight vertical or horizontal lines. The fact is, a trackball is just as accurate as a mouse and more so than a track-pad. Many early graphics designers preferred using trackballs over mice when working on computers.
 
What Is The Advantage Of Trackball Over Mouse?
 
The advantage of trackballs over mice are:
  1. The trackball is stationary so it does not require much space to use it.
  2. You can place a trackball on any type of surface, including your lap.
  3. A trackball mouse has ergonomic advantages because you move the ball and not the mouse itself.
 
What Are The Disadvantages Of A Trackball?
 
  1. Left-handed trackballs are difficult to find.
  2. Trackballs are expensive.
  3. A trackball requires fine control of the ball with just one finger or thumb.
  4. Difficult to Use.
  5. These are asymmetric and work on this principle.

+  Optical Mouse

what is a optical mouse

An Optical Mouse is an advanced computer pointing device that shines a bright light down onto your desk from an LED (light-emitting diode) mounted on the bottom of the mouse. The light bounces straight back up off the desk into a photocell (photoelectric cell), also mounted under the mouse, a short distance from the LED. In practice, an optical mouse does not need cleaning, because it has no moving parts.

Is an optical mouse better or laser?

Optical is more accurate than laser. Higher DPI is always better. Acceleration is the devil. Wireless mice are leggier than wired.
 

What Is The Advantage Of A Optical Mouse?

The advantage of optical mouse are:

  1. No moving parts means less wear and a lower chance of failure.
  2. There’s no way for dirt to get inside the mouse and interfere with the tracking sensors.
  3. Increased tracking resolution means smoother response.

The 4 Best Optical Mouse for Every Budget

  1. Logitech MX Ergo Wireless Trackball Mouse ($77.00)
  2. Mad Catz R.A.T. 8+ ($82.99)
  3. Razer Basilisk Essential ($29.00)
  4. SteelSeries Rival 650 ($119.00)

+  Wireless Optical Mouse

A Wireless Optical Mouse is a convenient choice for many computer users. Wheeled mice can collect dust, dirt and debris inside the wheel trap, causing the mouse to function improperly or not respond at all to movement. Optical mice, on the other hand, use an LED (light-emitting diode) to sense mouse movement.

Is an wireless optical mouse better or laser?

Optical is more accurate than laser. Higher DPI is always better. Acceleration is the devil. Wireless mice are leggier than wired.
 

What Is The Advantage Of A Wireless Optical Mouse?

The advantage of wireless optical mouse are:

  1. Greater freedom – another favorite feature among gamers, who often control their TVs from the couch
  2. Improvements in response time and accuracy
  3. Fewer cords
  4. Smoother movement due to the lack of a cord
