• 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…

• A Novel Multi-Stage Approach to the Detection of Visuo-Spatial Neglect Based on the Analysis of Figure-Copying Tasks

  R. M. Guest, M. C. Fairhurst · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper presents a computer-based technique for improving the detection of visuo-spatial neglect (VSN), a dysfunction typically caused by stroke that causes patients to fail to respond to stimuli on the opposite side of the visual field from the brain lesion. Early and…
