• Effect of Age and Parkinson's Disease on Cursor Positioning Using a Mouse

  Simeon Keates, Shari Trewin (2005) — Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  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…

• The Migratory Cursor: Accurate Speech-Based Cursor Movement by Moving Multiple Ghost Cursors Using Non-Verbal Vocalizations

  Yoshiyuki Mihara, Etsuya Shibayama, Shin Takahashi (2005) — Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper presents the migratory cursor, a novel voice-controlled cursor movement interface that combines two complementary techniques to achieve both speed and accuracy. The fundamental challenge with speech-based cursor control is that existing ap…

• Toward Goldilocks' Pointing Device: Determining a "Just Right" Gain Setting for Users with Physical Impairments

  Heidi Horstmann Koester, Edmund LoPresti, Richard C. Simpson (2005) — Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper describes the design and evaluation of the Input Device Agent (IDA), a software-based agent that automatically recommends a pointing device gain (control-display sensitivity) setting for individual users with physical impairments. Gain det…
