• Help Kiosk: An Augmented Display System to Assist Older Adults to Learn How to Use Smart Phones

  Zachary Wilson, Helen Yin, Sayan Sarcar, Rock Leung, Joanna McGrenere · 2018 · Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '18)

  This demonstration paper presents Help Kiosk (HK), a system that uses a large 19-inch touchscreen display to temporarily augment a smartphone's small screen during learning episodes for older adults. The system addresses two converging trends: rapidly growing populations of…

• Verification of Computer Display Pre-compensation for Visual Aberrations in an Artificial Eye

  Miguel Alonso Jr., Armando Barreto, Julie A. Jacko, Malek Adjouadi · 2005 · Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper presents experimental verification that computer display images can be pre-compensated to counteract the visual aberrations present in an optical system, specifically tested using a constructed artificial eye. The research builds on earlier theoretical work by Alonso…

• Image Pre-Compensation to Facilitate Computer Access for Users with Refractive Errors

  Miguel Alonso, Armando Barreto, J. Gualberto Cremades · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents a novel approach to improving computer access for people with refractive visual errors by pre-compensating displayed images using knowledge of the user's specific optical aberration. The core insight is that the human eye can be modelled as a Linear Time…
