“…However, the focus of rehabilitation engineering is much broader than just computer use. Rehabilitation engineering focuses on developing engineering models of human performance (Kondraske 1988a, Kondraske 1995, Persad et al 2007) and often measures that performance on task batteries that include many non-computer-related tasks (Kondraske 1990a, Kondraske 1990b, Smith and Kondraske 1987. Also, accommodations in rehabilitation engineering are often custom add-on devices or machines, giving rehabilitation engineering much in common with assistive technology.…”

____________________________________________________________Current approaches to accessible computing share a common goal of making technology accessible to users with disabilities. Perhaps because of this goal, they may also share a tendency to centralize disability rather than ability. We present a refinement to these approaches called ability-based design that consists of focusing on ability throughout the design process in an effort to create systems that leverage the full range of human potential. Just as user-centered design shifted the focus of interactive system design from systems to users, ability-based design attempts to shift the focus of accessible design from disability to ability. Although prior approaches to accessible computing may consider users' abilities to some extent, ability-based design makes ability its central focus. We offer seven ability-based design principles and describe the projects that inspired their formulation. We also present a research agenda for ability-based design.

“…[5] That is, for some older adults, more interaction steps and thinking time for small screen interaction were needed, especially for diverse characteristics of the older population. Altogether, results of this study and the previous works suggested that the elderly tend to require more interaction steps than the other age groups.…”

Abstract. Small touch screens are widely used in applications such as bank ATMs, point-of-sale terminals, ticket vending machines, facsimiles, and home automation in the daily life. It is intuition-oriented and easy to operate. There are a lot of elements that affect the small screen touch performance. One of the essential parts is icon feedback. However, to merely achieve beautiful icon feedback appearance and create interesting interaction experience, many interface designers ignore the real user needs. It is critical for them to trade off the icon feedback type associated with the different users needs in the touch interaction. This is especially important when the user capability is very limited. This paper described a pilot study for identifying factors that determine the icon feedback usability on small touch screen in four older adult Cognitrone groups since current research aimed mostly at general icon guidelines and recommendations and failed to consider and define the specific needs of small touch screen interfaces for the elderly. In this paper, we presented a concept from the focus on human necessity and use a cognitive assessment tool, which is, Cognitrone test, to measure older adult's attention and concentration capability and learn more about how to evaluate and design suitable small screen icon feedback types. Forty-five elder participants were participated. Each subject was asked to complete a battery of Cognitrone tests and divided into 4 groups. Each subject was also requested to perform a set of 'continuous touch' usability tasks on small touch screen and comment on open-ended questions. Results are discussed with respect to the perceptual and cognitive factors that influence older adults in the use of icon feedback on small touch screen. It showed significant associations between icon feedback performance and factors of attention and concentration. However, this interrelation was much stronger for the Group 2 and Group 4, especially for Type B, Type C and Type G. Moreover, consistent with previous research, older participants were less sensitive and required longer time to adapt to the high-detailed icon feedback. These results are discussed in terms of icon feedback design strategies for interface designers.

Abstract. This article concerns with human-computer-interaction (HCI) from a neuroscientific perspective. The motivation for this perspective is the demographic transition, which shifts population structures of industrial nations. The authors will explain consequences of the demographic transition in terms of HCI and establish a hypothesis for these research activities. To evaluate this hypothesis the authors develop an approach, which combines different disciplines. This approach examines the effects of IT-accessibility on human cognitive processing. Therefore, required methodologies and instruments will be explained, discussed and selected. Possible effects of IT-accessibility on human cognitive processing will be illustrated with an acknowledged cognition model. The result of this article will be a concept, which enables the measurement of IT-accessibility impacts on human cognitive processing.
