Computer Mouse

A computer mouse (or mice) is an input peripheral device that is used to manipulate a cursor on screen (applies to GUI environments only). A computer mouse was first introduced using a ball for feedback under it. This meant that any flat surface you drag the mice across, the ball moves and it controls two gears which is used for specific coordinates (X and Y). Later than, modern mouses use a new technology with Optic Sensors. The sensor tracks movement under the mouse on a flat surface, and feedback the information to either the mouse’s onboard chip to move to the system, or directly.


There are a variety of different mouses to support different people. As people can either prefer a different hand grip, may be left handed or a certain technology of a mouse. You can find the kind of mouse you prefer with light research.

Different Grips

When it comes to ergonomics, your chair, keyboard and mouse are probably the most important. Mouses comes with a variety of styles and designs, but there are 3 types of ergonomics

Palm Grip

The palm of is one of the most famous ways to use a computer mouse and mostly default. It’s found comfortable for a user who doesn’t want to move the mouse by lifting it and making adjustments with their fingers and palm. This is done by simply resting your palm against the lower surface of your mouse.

The palm grip is moved by the user’s forearm and wrist to push the mouse around. Doing this, the user can move the mouse much faster. This does not mean that the user have more control of their cursor however. Because they are moving with their wrist and forearm, the user doesn’t have precise control over it.. The palm grip is considered the most comfortable grip style for an extended use of time (for gaming mainly) without any fatigue or injury.

Claw Grip

The claw grip is used by users to need precise and quick movements. The user will move the mouse by pulling it around the surface as the user’s hand is positioned right above the mouse, but the lower palm of the user is still resting on the lower surface of the mouse. The user’s fingers touching the mouse’s buttons is also in the shape of a curve. This means that pressing the left or right mouse button can be done more responsively and quicker than the other grips. This also means that the user tends to exert more force into the buttons because of their finger style.

The problem with claw grips however is fatigue. While this is not as much as the ‘Fingertip Grip’, it should be noted to be uncomfortable for some users. This is because the user has their hand above the mouse, and they mainly move it with their hand and wrist.

Fingertip Grip

The fingertip grip is very similar to the claw grip, but differs because the of the increased agility the user gets. The user of this grip will pull the mouse along the surface, but the lower palm of the user is no longer resting on the lower surface of the mouse. The user has more control of their mouse this way and can respond much quicker. Like the claw grip, the user can press the left and right mouse buttons much quicker. However, the Fingertip grip is most likely the most exhausting mouse style. A user should only use this grip if they require stability and precise movements of their mouse. Nevermind the fact that this grip is very tedious, this grip is also the least common. This is because of not only fatigue, but the fact that it’s very hard to learn (as more control over the mouse needs to be practised along with the arched fingers). The fingertip grip is also known to cause Carpal Tunnel because the user’s wrist is in a ‘sloped’ position.


The technology of a mouse is mainly comprised of it’s insides. Whether the sensors are very accurate, buttons are strongly built, the outer shell of a mouse is made from actual steel or if there are any side buttons.


There are really two general kinds of sensors: A ball mice and a optical sensor.

  • Ball Mice: Ball mice’s includes a ball built into it, but barely sticking out on it’s bottom. When dragged across a surface, the ball rolls and starts to spin gears inside of it and feedsback the X and/or Y coordinate to the computer system.
  • Trackball: Trackballs are mouses with the ball sticking on above the surface rather than under it. This is controlled by the user moving the ball with their thumb, and clicking with their index and middle finger. There is a sense of more control using a trackball but are very uncommon.
  • Optical Mice: A LED is embedded inside the mouse and it points out to a hole on the bottom of the mouse to detect movement relative to the surface. Essentially, it is able to manipulate the cursor by the laser detecting surface movement and feeding back to the computer. Because of this, mouses won’t work on Glass or transparent surfaces because of no surface to reflect off of. Advanced mouses like Logitech’s Darkfield mouses are able to be operable on glass surfaces.


These are the technical terms used when talking about mouses. These can also be specifications.

  • Ambidextrous: A mouse designed to be used with the user’s left or right hand.
  • Dots Per Inch (DPI): DPI is the measurement of how many pixels the user’s mouse can cover by moving it in a single physical inch.
  • Software (driver): The software or driver on certain mouse’s allows you to change it’s settings. Whether it be sensitivity, macros or full functioning support. You can also have profiles to change settings quickly.
  • Ergonomics: The concern of the comfort of a device. In mouses, you can talk about grips, designs and style.
