There are many ways that people with disabilities can get information and perform everyday tasks.

People who have difficulty typing or using their hands work with

  • adaptive keyboards, trackballs, and pointing devices;
  • tools to press keys and operate controls;
  • assistive technology to minimize the effect of tremors or to enable activation of multiple key-presses simultaneously; and
  • voice-controlled software.
