Issues

Control Panel Buttons (6 of 11)

Issue: Buttons do not provide a surface that facilitates button activation.

A numeric keypad and other control panel buttons are shown.  The buttons are shown to be slick in texture and convex in shape.

Buttons that are slick or have no concave curvature are more difficult for some users to activate. Users without fine motor control or users that utilize manipulation sticks may have difficulty activating buttons that are slick and not curved inward, because their fingers or manipulation sticks may slip off the button and activate adjacent buttons.

Populations Impacted: Users with upper mobility impairments.

Potential Solutions:
  • The buttons on the device should be concave. Concave buttons help prevent users' fingers from slipping off the buttons.

  • A numeric keypad and other control panel buttons are shown.  The buttons are shown to be rubbery in texture and concave in shape.
  • The buttons on the device should be made from a high friction material. A rubberized coating or other high friction material helps prevent users' fingers from accidentally slipping off the controls.
