Issues

Barcode Readers (4 of 4)

Issue: Insufficient feedback is provided when a product is scanned.

A user's hand is shown grasping a handheld barcode reader and using it to scan an item.  There is no indication of visual or audible feedback from the kiosk.

Feedback should be provided to all users when a product is scanned, so that the user is informed that the product was successfully scanned. If feedback is provided in only one modality (e.g., visually), then users with impairments in that modality will not perceive the feedback. If feedback is insufficiently noticeable (e.g., a low-volume sound or brief flash of light), users may fail to perceive it.

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

Potential Solution:
  • Provide a clear indication, both visually and audibly, that a product has been scanned successfully. Visual feedback can be provided in the form of an on-screen message or by a light that illuminates on or near the scanner unit. Auditory feedback might consist of a simple beep or a voice message that reports the name and/or price of the product that was scanned.

  • A user's hand is shown grasping a handheld barcode reader and using it to scan an item.  Audible feedback (a tone from the reader) is indicated.
