• Barrier pointing: using physical edges to assist target acquisition on mobile device touch screens

  Jon Froehlich, Jacob O. Wobbrock, Shaun K. Kane (2007) — Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Froehlich, Wobbrock and Kane propose barrier pointing: a set of stylus-based target acquisition techniques that exploit the raised physical edge of a mobile touch screen to stabilise input for users with motor impairments. Standard touch-screen tappi…

• Exploring Methods to Improve Pen-Based Menu Selection for Younger and Older Adults

  Karyn Moffatt, Joanna McGrenere (2009) — ACM Transactions on Accessible Computing

  This study investigates why users struggle with pen-based menu selection on tablet PCs, particularly older adults, and tests two approaches for reducing errors. Building on a baseline study that identified three error types (slipping, drifting, and "…

• Two-In-One: A Design Space for Mapping Unimanual Input into Bimanual Interactions in VR for Users with Limited Movement

  Momona Yamagami, Sasa Junuzovic, Mar Gonzalez-Franco, Eyal Ofek, Edward Cutrell, John R. Porter, Andrew D. Wilson, Martez E. Mott (2022) — ACM Transactions on Accessible Computing

  This paper addresses a significant accessibility barrier in virtual reality: the requirement to use two motion controllers simultaneously for bimanual interactions. Many VR applications assume users can hold and manipulate two controllers, excluding …
