“…Research literature has reported that learning to use computers involves various aspects of physical development. Active research areas include (1) repetitive strain injury; eye dysfunction and sight deterioration; head, neck, and lower back problems; and other health hazards (Harwin and Haynes, 1992;Lee and Houston, 1986); (2) children's motor skills and their use of mouse, trackball, joystick, helmet-mounted sight, touch screen, eye tracker, keyboard, and other input devices (Lee and Houston, 1986;Scaife and Bond, 1991); (3) the readability of computer screen designs (Dyson and Haselgrove, 2001;Feldmann and Fish, 1988;Grabinger, 1993); and (4) people with special needs, such as visually impaired children and very old computer users (Neuman, 1991;Lawhorn, Ennis, and Lawhorn, 1996;Jacko and others, 2000).…”

What is the relation between information technology and human development? This is one of the big questions for contemporary developmental scientists. An enormous research literature has documented how information technologies shape human development cognitively (Papert, 1980(Papert, , 1993, socially (Turkle, 1984(Turkle, , 1995, and physically (Harwin and Haynes, 1992). However, how human beings, particularly ordinary children and adults, master information technology cognitively (understanding the Internet, for example), socially (such as building social network), and physically (for example, learning to use a mouse) has not yet been studied adequately and systematically. As a result, dynamic reciprocal interactions between information technology and human development have been often oversimplified as a static one-way process in which information technology controls human beings. While computer scientists are designing human-centered computers that adapt to people rather than the other way around (Dertouzos, 2001), developmental research will soon fall far behind the technological advances if the research continues to focus on how technology affects people rather than on how people interact with technology.We thank Joshua Smith and Heping Hao for their feedback on the early version of this chapter

“…These studies have addressed the relative performance of a cohort of users with visual impairments due to ocular disease and a cohort of age-matched controls without ocular dysfunction on several desktop computer tasks. Assessments of the interactions are achieved via traditional time and accuracy measures of performance, but also physiological methods such as electroencephalogram (Jacko et al 2000a) and eye tracking (Jacko et al 2000b). HCI issues considered relative to visual profile include: 1) the visually rigorous task of icon search and selection in the presence of distracters (Jacko 1999, 2000c, 2001; 2) cursor movement (Jacko et al 2000c); 3) the direct manipulation of drag and drop in the absence of distracters (Jacko et al , 2004a; and 4) the identification and selection of targets in a dropdown menu with distracters (Edwards et al 2004Jacko et al in press).…”

This study investigates factors affecting handheld human -computer interaction (HCI) for older adults with Age-related Macular Degeneration (AMD). This is largely an uncharted territory, as empirical investigations of HCI concerning users with visual dysfunction and/or older adults have focused primarily on desktop computers. For this study, participants with AMD and visually healthy controls used a handheld computer to search, select and manipulate familiar playing card icons under varied icon set sizes, intericon spacing and auditory feedback conditions. While all participants demonstrated a high rate of task completion, linear regression revealed several relationships between task efficiency and the interface, user characteristics and ocular factors. Two ocular measures, severity of AMD and contrast sensitivity, were found to be highly predictive of efficiency. The outcomes of this work reveal that users with visual impairments can effectively interact with graphical user interfaces on small displays in the presence of low-cost, easily implemented design interventions. Furthermore, results demonstrate that the detrimental influence of AMD and contrast sensitivity on handheld technology interaction can be offset by such interventions. This study presents a rich data set and is intended to inspire future work characterizing and modeling the interactions of individuals with visual impairments with non-traditional information technology platforms and contexts.
