Detailed explanation-1: -Adapted keyboard Even the humble mechanical keyboard has seen numerous improvements for persons with a physical disability, limited dexterity, tremor, Repetitive Strain Injury (RSI), Carpal Tunnel Syndrome (CTS) or any other physical or neurological condition.
Detailed explanation-2: -Trackballs are still used as separate input devices with standard desktop computers, but this application is also moving to touchpads due to the prevalence of multi touch gesture control in new desktop operating systems.
Detailed explanation-3: -People with disabilities, especially those with spinal cord injuries, can flexibly operate only above their neck, so most of the existing mouse assistive tools are implemented based on eyes, head, mouth, or blowing and sucking movements in order to provide the basic mouse functions [2, 3, 4].
