Issues

Control Panel Buttons (11 of 11)

Issue: Some types of buttons do not respond to touch from materials other than skin.

Certain types of controls, such as electrostatic buttons, do not respond to touches from materials other than skin. Users with prosthetic limbs and users who use manipulation sticks are therefore unable to activate these buttons.

Populations Impacted: Users with upper mobility impairments.

Potential Solution:
  • Ensure that controls can be activated by materials other than skin. Provide mechanically activated controls, or touch-sensitive controls that use a detection technology that responds to a variety of materials other than skin. However, care must be taken to ensure that the controls are not too sensitive, so that accidental activations become a problem.
