This section presents summary lists of recommendations for design issues related to access for persons with disabilities. Item numbers are based on lists in related sections of this appendix.
9. Recommendations for 3.5-inch floppy disk drives
Recommended
Visual Displays and Indicators:
3 Make LCD and LED indicators, warning, and alert lights software-readable.
Sound:
4 Provide a visually distinct indicator for all alerts or warning sounds created by hardware.
5 Provide visual indication of important sounds generated in normal computer operation.
Manipulation and Physical Design:
1 Eject media a sufficient distance for grasping.
2 Sculpt or bevel device entry slots.
3 Make latches operable with one hand.
4 Minimize the force required for inserting and retrieving media.
5 Ensure that media takes rough handling, and use caddies for media that do not.
6 Provide error flags for misinserted media, especially CDs.
7 Ensure that devices do not generate electromagnetic or RF fields that would affect users with hearing aids.
8 Use media misinsertion blocking.
11 Minimize operation noise levels.
Input and Controls:
1 Allow connection, substitution, or addition of alternative input devices.
2 Design controls to operate from the keyboard.
3 Mount all controls mounted on the front of the device.
4 Limit button design primarily to push-button controls.
5 Use concave buttons, especially where sustained force is required.
6 Avoid twisting motions.
7 Minimize the force required for operation.
8 Make all controls operable with one hand.
11 Make controls tactually discernible.
Labeling:
2 Use tactually distinct icons for controls, connectors, and legends.
3 Provide optional Braille and tactile labels.
