A large portion of the United States population is aging and desire to stay healthy. Smart speakers offer a potential platform for voice user interface (VUI) tools aimed at improving the tracking of cognition and potentially aiding the diagnosis of cognitive decline and dementia. Need finding interviews, task based usability sessions, and a five-week in home usability trial were used to determine the feasibility of a VUI cognitive tracking tool. The research yielded design implications for future smart speaker based cognitive tracking interfaces.
Any research projects that don't have a permanent lab affiliation with GVU and are participating in the GVU Center Research Showcase will display their projects here. These projects are by researchers who are partnering with GVU to showcase their work in people-centered computing or using computing technology to solve scientific, social and technical challenges.
Faculty can request at any time to have their lab listed on the GVU website by emailing firstname.lastname@example.org.
