The Computer Mouse Tale
This electronic critter is an important tool for typing in text and data and navigating around your PC. Most are fitted with one or more buttons and curved to sit under the hand. You can choose between the Mechanical, Optical or Laser mouse.
The Mechanical Mouse
The mechanical mouse contains a ball that translates hand movements into movements of the cursor on your screen. Aspects of the mechanical mouse to consider are:The Optical Mouse
An optical mouse looks very similar to a mechanical mouse, except the underside contains an LED (Light Emitting Diode) instead of a ball. The LED projects light on the surface it is on and uses it to track exact movements. Aspects of the optical mouse to consider are:- They are quicker than a mechanical mouse.
- Need less maintenance.
- Optical mice cannot track on glossy and transparent surfaces, including many commercial mouse pads, although optical mouse pads are readily available.
- Optical mice with less image processing power have problems tracking extremely fast movement, although high-end mice track at more than 40 inches per second.
- Their performance with multi-coloured mousepads is sometimes unreliable.
- If the device is used with the proper surface, sensing is more precise than with a mechanical mouse.
- The optical mouse is an asset in graphics applications, and it makes computer operation easier in general.
The Laser Mouse
This mouse uses a small laser instead of an LED. The new technology can increase the detail of the image taken by the mouse. Some claim that this leads to a 20 times increase in the sensitivity to the surface features used for navigation. The Laser mouse runs on batteries.

Mouse speed
What else to look for in a computer mouse
- Ergonomically friendly.
- Magnifying tool.
- Programmable thumb buttonsfor convenience and speed.
- scroll wheel is a very useful wheel in the middle of a mouse that enables you to scroll the page.
- If you are looking for portability or flexibility check out wireless mice.
Alternative mice
- Mini-mouse - a small egg-sized mouse optimized for portability (often used with laptop computers).
- Trackball - user moves a ball mounted in a fixed base.
- Foot mouse - a mouse variant for those who do not wish to or cannot use the hands or the head: instead footclicks are used.
- Camera mouse - a camera tracks the head movement and moves the onscreen cursor.
- Palm mouse - held in the palm and operated with only 2 buttons; the movements across the screen correspond to a feather-light touch and pressure increases the speed of movement.
Mousepad
On some surfaces such as wood grain, they are not necessary for optical mice.

Wonderful lens. More informative about computer mouse. I could know about Laser Mouse only from this lens. Good job. Thanks for sharing the information. In computers we use numerous software. To run the software properly and effectively in a computer, Software Testing is inevitable. I come across a good stuff site about ISEB Software Testing on ISEB Software Testing Please stop by to grab information about ISEB Software Testing. Posted May 21, 2008 |
