Graphic Input Device

A hardware device used to input and manipulate visual graphics on a computer, including digital drawing pads (digitizer tablets), styluses, mice, trackballs, touchscreens, and specialized assistive devices. For artists with upper limb motor impairments, the shape, size, pressure sensitivity, and interaction modality of graphic input devices directly affect creative capacity, pain levels, and drawing duration. Many artists use non-standard configurations—such as older discontinued stylus models with more comfortable shapes, external mice operated with the non-dominant hand, or touchscreens navigated with knuckles—because mainstream input devices do not accommodate their specific motor abilities.
