TL;DR: Transgenerational Design provides an excellent rationale for considering individual differences and human limitations during the design process, as well as some good general information regarding the types of changes that occur in their motor, perceptual, and cognitive skills as the authors age.
Abstract: THE STATEDgoal of Transgenerational Design is to sensitize designers and consumers to the physical, perceptual, and cognitive changes that occur with aging and to enable them to make intelligent decisions when designing, producing, marketing, specifying, or buying products or environments for the aging population. Despite the emphasis on the changes that occur with age, the book does not promote the design of products for a specialized, narrow market of persons commonly referred to as the elderly. Rather, it emphasizes the fact that aging is a continual process and that there are tremendous individual differences in both the timing and severity of the changes that occur with age. Pirkl advances the hypothesis that it is better to consider the changes that can occur with aging when designing typical consumer products or environments than it is to design specialized products for a narrow and ill-defined elderly population. Transgenerational Design covers a broad range of topics, including myths associated with aging, the role of older people in Western society, the demographics of the increasing elder population in the United States, several chapters on changes in motor skills and changes in perceptual and cognitive abilities that occur with age, and a discussion of quality of life and independence. The book ends with a discussion of the trans generational design promise and the bounty that can be reaped through careful and considerate design. Included are examples of several products that Pirkl offers as examples of transgenerational design and a case study on the design of a bathroom for the elderly. The book provides a good introduction to the concept of transgenerational design. Unfortunately, it lacks depth if one is looking for a reference of specific design recommendations or specifications. Overall, Transgenerational Design should benefit young designers and human factors and marketing personnel. It provides an excellent rationale for considering individual differences and human limitations during the design process, as well as some good general information regarding the types of changes that occur in our motor, perceptual, and cognitive skills as we age.
TL;DR: The findings demonstrate the need to include user characteristics in interface design and show that older users reached lower performance outcomes when using personal data management software applications of a PDA.
Abstract: The proliferation of ubiquitous computing is accompanied by the development of devices, which promise to facilitate the daily living activities of people. However, the question if mobile devices address the usability demands of older users is still unsettled. This paper reports the findings of a series of studies that examined the performance of younger and older adults when using personal data management software applications of a PDA. In order to learn about the ageing impact, the influence of user characteristics like spatial and memory abilities, the subjective technical confidence and computer-expertise on performance outcomes were analysed. Beyond quantitative performance measurements, the major shortcomings in interface design were identified. Results showed that older users reached lower performance outcomes. Even young adults did not reach a perfect performance level, hinting again at shortcomings in the design of PDA applications. Overall, the findings demonstrate the need to include user characteristics in interface design.
TL;DR: The results of the measurements of 33 anthropometric characteristics of 106 women aged 60 and above constitute a set of basic data for the design of functional space and devices, as well as clothes, for this age group as discussed by the authors.
TL;DR: In both the modification of old products and in design for compressed morbidity, there is a need for methods which encourage activity instead of just moderating the effects of infirmity.
