A subset of "Situationally Induced Impairments and Disabilities" (SIID), termed "Severely Constraining Situational Impairments" (SCSI), was explored at the user task and motivational level, to better understand the challenges faced by users attempting to perform tasks using a mobile device. Through structured interviews, participants were found to deploy workarounds in attempting to complete mobile I/O transactions, even if that workaround might place them in considerable danger. The motivations underlying user decisions were also explored resulting in a set of rich scenarios which will be used in the final participatory design stage of the study to discover ways that technology can be designed to overcome SCSIs.
Running offers a convenient and affordable method of keeping fit and maintaining good cardiovascular health. In this paper, we describe the experiences of a group of runners whose practices are rarely profiled: individuals who identify as legally-blind, some of whom run competitively, while others run for purposes of leisure. We specifically focus on planning strategies undertaken, experiences running both with and without sighted guides, the impact of situational and environmental factors, and the ways in which technology is utilized. The study has revealed a set of insights which if capitalized upon could offer considerable promise to support independent running. These include examining ways to reduce levels of uncertainty faced by runners, supporting autonomy, providing greater levels of environmental awareness, and aiding socialization when running. Findings from the work offer promise to interface designers to improve inclusiveness when developing technologies to support runners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
