A Mixed Method for Evaluating Input Devices with Older Persons
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, whic…

Gestural Text Entry on Multiple Devices
This paper from Carnegie Mellon University presents adaptations of the EdgeWrite unistroke text entry method across multiple computer input devices: styluses, touchpads, displacement and isometric joysticks, four keys or buttons, and trackballs. Edge…

Accuracy and Frequency Analysis of MultiTouch Interfaces for Individuals with Parkinsonian and Essential Hand Tremor
This 2005 study from the University of Delaware compares four computer pointing devices — an optical mouse, optical trackball, isotonic joystick, and a FingerWorks MultiTouch Surface (MTS) — for users with Parkinsonian tremor and essential tremor. Th…

Investigating the Applicability of User Models for Motion-Impaired Users
This paper from the University of Cambridge investigates whether the Model Human Processor (MHP) — a foundational user model from Card, Moran, and Newell's "The Psychology of Human-Computer Interaction" — accurately describes how motion-impaired user…

A Model of Keyboard Configuration Requirements
This paper from the University of Edinburgh presents a user model — a computer program that observes a person's typing behaviour and automatically identifies keyboard difficulties, then recommends appropriate configuration settings. The model address…

Helping Older Adults Locate 'Lost' Cursors Using FieldMouse
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 am…

Text Entry via Discrete and Analog Myoelectric Signals
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 contro…

Text Entry by Raising the Eyebrow with HaMCoS
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 c…

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

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