Design research has much to contribute to and much to gain from the emerging field of possibility studies. In this short essay, I discuss these opportunities with respect to four topics: (1) processes of mediation and representation, (2) systems perspectives on creative work, (3) methodological options for investigation, and (4) educational challenges that should be addressed. Considering design research's contributions to each of these topics raises interesting questions that possibility studies might address as it develops. Conversely, possibility studies is already raising issues that design research should also attend to.
Diagrams are effective instruments of thought and a valuable tool in conveying those thoughts to others. As such, they can be usefully employed as representations of a research domain and act as stimulus materials in interviews. This process of graphic elicitation may encourage contributions from interviewees that are difficult to obtain by other means. By representing concepts and relationships that other visual artefacts cannot depict, diagrams provide a complementary addition to conventional interview stimuli. This article discusses the application of graphic elicitation within the broader context of the diagramming process. Consideration is given to the unique characteristics of diagrams and the ways in which they are interpreted. Thus, the specific benefits that diagrams offer as interview stimuli may be understood. Following this, an example study is described in which the graphic elicitation process was employed in interviews with industrial designers. Reporting on a study in which the interviewees possessed a well-developed graphic sensibility allows a broad range of graphic elicitation's potential benefits to be illustrated. In closing the article, a discussion is held on the range of methodological issues that must be addressed when employing diagrams in a research study.
Objective: Patterns of capability loss and disability onset among older people were investigated prospectively. Background: With aging, the gap between personal capability and environmental demand becomes wider, resulting in higher levels of disability in daily activities. Methods: Data from a longitudinal, population-based study were obtained for analysis, which recruited a representative sample of 13,004 people aged 65 years and older from five sites in Great Britain. Participants completed a baseline interview during 1990 to 1994 and follow-up interviews after 1, 2, 3, 6, 8, and 10 years. Those who reported full vision, hearing, thinking, locomotion, reaching, and dexterity ability as well as no disability in cooking, housework, shopping, and transportation at baseline were included in a survival analysis. Results: Locomotion was the first ability to be lost, followed by reaching, thinking, hearing, vision, and dexterity. Age at onset of disability was earliest for shopping, then housework, transportation, and cooking. Women were consistently younger at capability loss and disability onset than men except in terms of hearing and cooking. Conclusion: These findings suggest that capabilities required for product and service interaction follow a hierarchical pattern of loss, which has practical implications for design. Although interventions to reduce disability in the older population are likely to require changes that address more than one demand, capabilities lost early in old age should take precedence over those lost later. Application: A potential application of this research is in the development of an overall design strategy to enhance older people's ability to live independently.
