Barrier pointing: using physical edges to assist target acquisition on mobile device touch screens
Froehlich, Wobbrock and Kane propose barrier pointing: a set of stylus-based target acquisition techniques that exploit the raised physical edge of a mobile touch screen to stabilise input for users with motor impairments. Standard touch-screen tappi…

A comparison of area pointing and goal crossing for people with and without motor impairments
Wobbrock and Gajos at the University of Washington present a controlled study comparing two fundamentally different target-acquisition paradigms — conventional area pointing (move into a confined region and click) and goal crossing (sweep the cursor …

Slipping and drifting: using older users to uncover pen-based target acquisition difficulties
Moffatt and McGrenere present an empirical study at the University of British Columbia investigating the underlying causes of pen-based target acquisition difficulty on a Tablet PC, with explicit attention to how age affects targeting ability. Thirty…

Developing Steady Clicks: A Method of Cursor Assistance for People with Motor Impairments
This paper from IBM Research and the University of British Columbia presents Steady Clicks, a cursor assistance feature designed to reduce clicking errors for mouse users with motor impairments. The system addresses three specific error types identif…

Mouse Movements of Motion-Impaired Users: A Submovement Analysis
This paper presents a detailed submovement analysis of mouse cursor trajectories from six motion-impaired users (four with cerebral palsy of varying types — athetoid, athetoid with spasm, and general — and one with Friedrich's ataxia and tremor) and …

Cursor Measures for Motion-Impaired Computer Users
This paper systematically analyses cursor movement patterns of motion-impaired computer users to understand the specific difficulties they face with point-and-click interactions in graphical user interfaces. The authors argue that existing cursor mea…

A Framework of Assistive Pointers for Low Vision Users
This paper from the University of Saskatchewan proposes a four-dimensional framework for systematically exploring the design space of assistive mouse pointers for low vision computer users. The authors argue that while various pointer assistance tech…

Neck Range of Motion and Use of Computer Head Controls
This study from the University of Pittsburgh investigates the relationship between neck range of motion and performance when using computer head controls — devices that translate head movements into cursor movements on screen. The research involved 1…

Low Vision: The Role of Visual Acuity in the Efficiency of Cursor Movement
This study investigates how visual acuity affects cursor movement efficiency for users with Age-related Macular Degeneration (AMD), the leading cause of visual impairment for Americans aged 75 and older. The researchers note that while existing acces…

Towards Accessible Touch Interfaces
This paper presents an empirical evaluation of touch screen interaction techniques with 15 tetraplegic users, aiming to provide evidence-based guidance for designing accessible mobile touch interfaces. The authors recognized that while touch screen d…
