Abandonment of devices occurs for varying reasons. The device may be unreliable, not perform as expected or be too difficult to use. The most frequent reason for abandonment is not including the user in choice of the device. People with disabilities are like everyone else in that they want technology which is reliable, meets the need and is affordable, too. For someone who needs AT to carry out critical and valued occupational performance, AT is a necessity.
All individuals vary.
The need for AT varies from person to person based on individual needs and valued interests.
