Abstract: This research suggests the use of DOWELL, a dwell-time-based smartphone control solution, for people with upper limb disabilities who are unable to interact with an interface. DOWELL is an application for smartphones that uses existing computer assistive devices and does not require additional assistive devices for smartphones. User interviews and task analysis results from eight participants with upper limb disabilities informed four design implications to create dwell-time software for smartphone so this have difference with solution for computer. Guardrail UI uses the edge of the mobile device to help people with upper limb disabilities. The use of various gestures on a smartphone without clicking is also suggested.
