Site Accessibility

There are a number of ways to make viewing this site easier if you are experiencing problems accessing some of the information. For further information on more specialist equipment and software for blind people, please visit the products section of the RNIB website.

Operating systems

Both Windows and Mac OS provide some control over the working environment of the computer desktop through control panels (available via Start then Settings on a PC or the Apple menu on a Mac). The options vary between systems and between different versions of the same system. Consult your operating system manual or on-screen help for more detailed instructions.

Monitor

There are a two main ways to control the monitor display to make it easier to view.

Contrast - increasing the contrast, either by a control on the monitor itself or through an on-screen control panel, allows you to improve the definition of images and text.

Colours - the colours of different components of the desktop display, such as window frames and the desktop itself, can be changed to make items easier to see.

Mouse

The pointer can be made bigger (PCs only) or to move at different speeds. It can also be made to create a 'jet-stream' trail as it moves, which makes it easier to follow its movements.

Keyboard

There are a number of alternatives on the keyboard to make it easier to use.

'Sticky' keys - this feature allows you to set a modifier key such as SHIFT, ALT or CTRL to stay on until another key is pressed. This helps people who cannot press two keys simultaneously.

'Filter' or 'slow' keys - this feature instructs the keyboard to ignore keys repeatedly pressed or keys touched momentarily. The rate at which the keyboard repeats a pressed key can also be modified from a control panel.

'Toggle' keys - this feature can be set to that the system plays a high sound when any of the LOCK keys are pressed and a low sound when deactivated.
