• Mouse Movements of Motion-Impaired Users: A Submovement Analysis

  Faustina Hwang, Simeon Keates, Patrick Langdon, John Clarkson · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  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 three able-bodied controls…

• Cursor Measures for Motion-Impaired Computer Users

  Simeon Keates, Faustina Hwang, Patrick Langdon, P. John Clarkson, Peter Robinson · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  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 measures, primarily developed by…

• Low Vision: The Role of Visual Acuity in the Efficiency of Cursor Movement

  Julie A. Jacko, Armando B. Barreto, Gottlieb J. Marmet, Josey Y. M. Chu, Holly S. Bautsch, Ingrid U. Scott, Robert H. Rosa · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  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 accessibility research has focused…

• A Comparison of Voice Controlled and Mouse Controlled Web Browsing

  Kevin Christian, Bill Kules, Ben Shneiderman, Adel Youssef · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This within-subjects study from the University of Maryland compared voice-controlled web browsing with traditional mouse-based browsing using 18 participants. The researchers used Conversa, a commercial voice browser from Conversational Computing that renders pages visually…

• Neck Range of Motion and Use of Computer Head Controls

  Edmund LoPresti, David M. Brienza, Jennifer Angelo, Lars Gilbertson, Jonathan Sakai · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  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 15 subjects without…

• A Study of Blind Drawing Practice: Creating Graphical Information Without the Visual Channel

  Hesham M. Kamel, James A. Landay · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper from UC Berkeley investigates how blind users create drawings and proposes a grid-based model for non-visual drawing tools. The researchers began by observing that existing drawing tools for blind users fail because they lack adequate contextual feedback — blind users…

• A Study of Input Device Manipulation Difficulties

  Shari Trewin · 1996 · Proceedings of the Second Annual ACM Conference on Assistive Technologies (Assets '96)

  This paper from the University of Edinburgh describes a pilot study designed to gather detailed, quantified data about physical input errors made by people with motor disabilities when using standard keyboards and mice. The author identifies a significant gap: despite widespread…
