Use Feedback

The user should receive immediate and tangible feedback during interaction with an application. Appropriate feedback includes acknowledging a request, pointing out an error, or tracking the progress of an operation. Although auditory feedback can be useful for attracting a user's attention, it should be used sparingly in a pen-based application for the following reasons:

  • Many users find beeps annoying.

  • Pen-based computers will be used more and more frequently in conference rooms and other group areas where beeping from a machine will not be welcome.

  • Auditory messages disappear without a trace. If the user is momentarily away or distracted, the auditory signal has failed to do its job.

  • If the user can turn the warning sound off, sound is not a reliable source of feedback.

  • An audible notification is not useful for users who are deaf or hard of hearing.
