A variety of physical difficulties when accessing computers can be aided by adjusting the Windows display. The most common solution is to make items larger and consequently easier to target with the mouse. People with dyspraxia, perceptuo-motor difficulties and tremors might benefit from having larger icons and text. Those with more severe physical difficulties such as head-pointer users could benefit even more by making items as large as possible without adversely affecting space on the screen.

Increase the DPI
This is the most ‘modern’ approach and works best with Windows 7 and Windows 8

Increase the Resolution
This is an easy adjustment that can be made to all versions of Windows but may cause the screen to blur slightly.

Adjust individual items
This involves the most work but can be used to customise just the items on the screen that are difficult to click on (such as icons).
