The ability to read labels is important to ensure that users are able to detect and recognize controls, connectors, and media interfaces. Users with low vision or blindness often have difficulty if these labels are printed in small or low-contrast type. All users have difficulty with small labels on the back or in hard-to-view areas of the product.
Hardware design strategies for providing greater access to labels include the following:
1. Use large, high-contrast, bold stroke, sans serif lettering, and avoid using artwork behind text.
This allows users with low vision or reduced vision to more easily read the lettering.
2. Use tactually distinct icons for controls, connectors, and legends.
Raised icons (raised at least 1/32 inch) allow users who are blind to more easily discern an item’s label by touch. They also allow any user to identify a component located out of view (such as on the back of the unit).
3. Provide optional Braille and tactile labels.
This allows users who are blind the option of customizing labels on the unit.
