• Touchpad Mapper: Exploring Non-Visual Touchpad Interactions for Screen-Reader Users

  Ather Sharif, Venkatesh Potluri, Jazz R. X. Ang, Jacob O. Wobbrock, Jennifer Mankoff · 2024 · Proceedings of the 21st International Web for All Conference (W4A)

  This technical note introduces Touchpad Mapper, a system that repurposes the laptop touchpad — a widely available but underutilized input device for screen-reader users — as a spatial interface for exploring 2D digital content non-visually. The authors argue that while touchpads…

• Speed-Dial: A Surrogate Mouse for Non-Visual Web Browsing

  Syed Masum Billah, Vikas Ashok, Donald E. Porter, IV Ramakrishnan · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17)

  This paper presents Speed-Dial, a system that uses an off-the-shelf Microsoft Surface Dial as a surrogate mouse for non-visual web browsing. The core problem it addresses is the fundamental mismatch between how sighted and blind users interact with the web: sighted users can…

• Text Entry by Raising the Eyebrow with HaMCoS

  Torsten Felzer, Stephan Rinderknecht · 2014 · ASSETS '14: Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility

  This demo paper presents HaMCoS (HAnds-free Mouse COntrol System), a system that enables text entry for people with very severe physical disabilities using tiny contractions of the brow muscle. The system targets users in a "locked-in" state, where communication with the outside…

• Text Entry via Discrete and Analog Myoelectric Signals

  Adam J. Sporka, Antonín Posusta, Ondrej Poláček, Tomáš Flek, Jakub Otáhal · 2014 · ASSETS '14: Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility

  This demo paper presents a prototype system for text entry using surface electromyography (sEMG) signals detected from muscles in the user's forearm. The system is intended for people with upper extremity disabilities who retain the ability to control their forearm muscles.…

• Effects of Target Expansion on Selection Performance in Older Computer Users

  Faustina Hwang, Nic Hollinworth, Nitin Williams · 2013 · ACM Transactions on Accessible Computing

  This research investigates target expansion as an assistive technique for improving mouse pointing performance in older computer users. Target expansion dynamically enlarges clickable targets as the cursor approaches, conserving screen space while providing larger click areas…

• Computer Usage by Children with Down Syndrome: Challenges and Future Research

  Jinjuan Feng, Jonathan Lazar, Libby Kumin, Ant Ozok · 2010 · ACM Transactions on Accessible Computing

  This landmark study presents findings from a large-scale survey of approximately 600 parents of children with Down syndrome (DS) about their children's computer usage challenges. The research addresses a critical gap: while DS characteristics are well-documented medically, their…

• Helping Older Adults Locate 'Lost' Cursors Using FieldMouse

  Nic Hollinworth · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This short paper describes FieldMouse, a modified standard optical mouse augmented with a touch sensor (Quantum QT110) embedded in its top surface to detect when a user grasps the mouse after releasing it. The motivation addresses a common problem among older adult computer…

• Goal Crossing with Mice and Trackballs for People with Motor Impairments: Performance, Submovements, and Design Directions

  Jacob O. Wobbrock, Krzysztof Z. Gajos · 2008 · ASSETS '08: Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility

  This study investigates whether goal crossing—an input technique where users move through a target boundary rather than clicking within it—can benefit people with motor impairments. The research compares crossing performance against traditional area pointing using a rigorous…

• A Mixed Method for Evaluating Input Devices with Older Persons

  Murni Mahmud · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This exploratory study introduces a mixed evaluation method for assessing common input devices used by older persons. The author argues that traditional input device studies rely too heavily on experimental tasks like Fitts's Law pointing tests, which use controlled stimuli that…
