This study explores factors affecting handheld computer interaction for older adults with Age-related Macular Degeneration (AMD). This is largely uncharted territory, as empirical investigations of human-computer interaction (HCI) concerning users with visual dysfunction and/or older adults have focused primarily on desktop computers. For this study,(More)
The current ubiquity of information technology has increased variability among users, creating a corresponding need to properly capture and understand these individual differences. This study introduces a novel application of multifractal statistical methods to distinguish users via patterns of variability within high frequency pupillary response behavior(More)
Enantioselective acylation of R-2-pentanol in a solid/gas reactor catalysed by lipase B from Candida antarctica. ABSTRACT The feasibility of the enzymatic enantioselective acylation of R-2-pentanol in a solid/gas reactor was demonstrated and compared to the same reaction carried out in liquid systems. This reaction was catalysed by lipase B from Candida(More)
PURPOSE To determine the impact of auditory and haptic (tactile) feedback on computer task performance of patients with age-related macular degeneration (AMD) compared to controls. METHODS Thirty patients with AMD and 29 similarly aged controls with no known ocular disease completed timed computer icon "drag and drop" tasks under all four possible(More)
