RESUMEN
Telepresence robots have recently been introduced as a way for children who are homebound due to medical conditions to attend their local schools. These robots provide an experience that is a much richer learning experience than the typical home instruction services of 4-5 hours a week. Because the robots on the market today were designed for use by adults in work settings, they do not necessarily fit children in school settings. We carried out a study of 19 homebound students, interviewing and observing them as well as interviewing their parents, teachers, administrators, and classmates. We organized our findings along the lines of the various tasks and settings the child is in, developing a learner-centered analytic framework, then teacher-, classmate-, and homebound-controller-centered analytic frameworks. Although some features of current robots fit children in school settings, we discovered a number of cases where there was a mismatch or additional features are needed. Our findings are described according to analytic frames that capture user experiences. Based on these user-centered findings, we provide recommendations for designing the robot and user interface to better fit children using robots for school and learning activities.
RESUMEN
Collaboration has become a dominant mode of scientific inquiry, and good collaborative processes are important for ensuring scientific quality and productivity. Often the participants in these collaborations are not collocated, yet distance introduces challenges. There remains a need for evaluative tools that can identify potential collaboration problems early and provide strategies for managing and addressing collaboration issues. This paper introduces a new research and diagnostic tool, the Collaboration Success Wizard (CSW), and provides two case studies of its use in evaluating ongoing collaborative projects in the health sciences. The CSW is designed both to validate and refine existing theory about the factors that encourage successful collaboration and to promote good collaborative practices in geographically distributed team-based scientific projects. These cases demonstrate that the CSW can promote reflection and positive change in collaborative science.
RESUMEN
Human-computer interaction (HCI) is a multidisciplinary field in which psychology and other social sciences unite with computer science and related technical fields with the goal of making computing systems that are both useful and usable. It is a blend of applied and basic research, both drawing from psychological research and contributing new ideas to it. New technologies continuously challenge HCI researchers with new options, as do the demands of new audiences and uses. A variety of usability methods have been developed that draw upon psychological principles. HCI research has expanded beyond its roots in the cognitive processes of individual users to include social and organizational processes involved in computer usage in real environments as well as the use of computers in collaboration. HCI researchers need to be mindful of the longer-term changes brought about by the use of computing in a variety of venues.
