Signature Area (1 of 4)

Issue: Users may not be sufficiently notified that input is required in the signature area.

On some kiosks, the signature area is in effect a secondary user interface, distinct and separate from the primary user interface. Users may not be sufficiently notified when they need to begin interacting with the signature area (to sign the screen, accept the signature, or input other information).

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

Potential Solutions:
  • Notify users when input is required in the signature area. The primary user interface should prompt the user (both visually and auditorily) when it is necessary to provide input in the signature area.

  • Integrate the signature area into the primary user interface. A design where the user can complete the entire transaction through a single user interface is preferable to one where the user must switch to a different user interface for part of the transaction. Users will be more likely to realize that additional input is required if the input can be provided through the interface they are already working with. If a secondary user interface must be used, ensure that the need to switch to the secondary interface is clearly communicated, and ensure that all necessary accessibility features are provided for the secondary interface. Ensure that once the user switches to the secondary interface, the transaction can be completed through that interface without switching back to the primary interface.
