An optimal mouse can either can an attached or wireless device used to move the cursor around and select objects on a computer screen. An optical mouse works by taking repeated images of its location and adjusts the cursor on the computer screen when the images it takes shifts direction. Optical mouse technology has improved greatly since the beginning of the computer age, but it does have its pros and cons. A mouse is typically graded on cursor accuracy, convenience, energy and surface compatibility.
Cursor Accuracy
The cursor accuracy of an optical mouse is typically high as it can analyze changing positions at 700 mm/sec and read up to 200 to 300 dots per inch. This means that it reads its location fast with high precision. In comparison to a mechanical mouse, an optical mouse does not wear down in accuracy because it does not have the same moving parts that a mechanical mouse has. However, the accuracy can be reduced if the open hole leading to the laser area is dirty.
