Control Panel Keypads (2 of 3)

Issue: Non-standard numeric keypads pose a problem for some users.

A nonstandard numeric keypad layout is shown, with the keys arranged into a 5-row diamond layout.

There are two standard layouts for numeric keypads, the telephone keypad layout and the adding machine layout (typical of most computer keyboards). Non-standard numeric keypad layouts create difficulties for users who are blind, who rely on the use of the standard layouts to orient themselves to the keypad, and for individuals with cognitive impairments, who may become confused when faced with a non-standard layout.

Populations Impacted: Users who are blind; users with cognitive impairments.

Potential Solution:
  • Use a standard keypad layout on the control panel for the kiosk. If a numeric keypad is used on the device, ensure that one of the standard layouts is used. Also, ensure that the keys are tactilely discernable, and provide feedback to the user when a key is pressed.
