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…

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…

Effect of Age and Parkinson's Disease on Cursor Positioning Using a Mouse
This paper presents a detailed empirical study examining how age and Parkinson's disease affect the ability to perform point-and-click tasks with a computer mouse. The researchers recruited 24 participants across four groups: young adults (ages 20-30…

Automating Accessibility: The Dynamic Keyboard
This paper presents the Dynamic Keyboard, a self-adaptive software agent developed at IBM's T.J. Watson Research Center that continuously and automatically adjusts keyboard accessibility settings to match the current user's typing patterns. The syste…

Speech-Based Cursor Control: A Study of Grid-Based Solutions
This paper investigates grid-based approaches to speech-controlled cursor positioning, addressing a well-documented weakness of speech recognition technology: while dictation-based text entry has improved dramatically, using speech for precise cursor…

A Comparison of Voice Controlled and Mouse Controlled Web Browsing
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 tha…

Understanding Pointing Problems in Real World Computing Environments
This paper develops techniques for collecting and analysing pointing performance data during real-world computer use, rather than solely in laboratory settings, to understand how pointing behaviour varies over time for individuals with motor impairme…

Hover or Tap? Supporting Pen-based Menu Navigation for Older Adults
This paper investigates "drifting" — an error specific to pen-based (Tablet PC) interaction where users accidentally hover over an adjacent menu head, causing their intended menu to close and the wrong one to open. This occurs because inductive pen t…

Input to the Mobile Web is Situationally-Impaired
This paper investigates the overlap between input problems experienced by mobile web users and those faced by disabled desktop users, particularly people with motor impairments. The author argues that these two domains are typically studied in isolat…
