Output Areas (2 of 3)

Issue: Users are not sufficiently notified when outputs are present in the output area.

A ticket output tray on a kiosk is shown.  Tickets that are dispensed into the tray are not clearly visible - visiblity of the ticket is obscured by the design of the tray, and the interior of the tray is dark.

On some kiosks, no indication that outputs have been dispensed (other than sounds associated with the dispensing, such as the sound of a printer working) is provided. This may result in users failing to realize that there are outputs that need to be retrieved, and leaving them behind when they complete their transactions.

Populations Impacted: Users who are blind; users with low vision; users who are deaf; users who are hard of hearing; users with cognitive impairments.

Potential Solutions:
  • Prompt the user to retrieve output, both visually and auditorily. Provide both on-screen text and/or graphics and auditory output indicating that outputs have been dispensed, and describing the location of the output area to users. Consider providing a light in or near the output area that illuminates to indicate the presence of outputs and to indicate the location of the output area.

  • Repeat prompts if outputs are not retrieved in a timely manner. If outputs remain in the output area after some period of time after the initial prompt (long enough to not be a nuisance to the user, but short enough that the user is notified before moving too far from the machine), prompt the user that there are still outputs that need to be retrieved. If the machine is attended, notifying the attendant may also be beneficial, so that the attendant can get the customer's attention and assist the customer with retrieving the items.

  • When possible, dispense all outputs into a single area. This enables users to retrieve all outputs at the same time, and avoids situations where users retrieve output from one area but forget to check other areas.

  • Ensure that outputs are clearly visible within the output area. Users should be able to tell at a glance if outputs are present in the output area. Outputs should be visible from either a seated or standing position.

  • A ticket output tray on a kiosk is shown.  Tickets are dispensed into a lighted tray with a cutout in the front to improve visibility of tickets in the tray.
  • Ensure that outputs are tactilely discernible within the output area. Design output areas so that users can quickly determine by touch if outputs are present. Ensure that outputs are ejected a sufficient distance from the machine to be tactilely located. Ensure that the output area does not provide any way for outputs to become hidden (for example, by slipping too far away from the opening of the output area).
