Imagined Device

An input device that exists only in the user's imagination, with no physical form, operated through gestures that draw on mental models of a real counterpart such as a smartphone, remote control, or joystick. Imagined devices are typically enacted on or around the body - for example, tapping the open palm as if it were a phone - and are sensed by cameras, wearables, or other external sensors. For people with motor impairments, imagined devices remove constraints of mass, grip, and button force, letting form and interaction emerge from individual abilities rather than hardware.
