Mobile phones and tablets are rapidly evolving consumer technologies that offer rich opportunities for supporting everyday tasks and vocations. Drawing on a decade of research into the use of these tools as assistive technology for cognition, this presentation will include discussion of: (1) the strengths and weaknesses of consumer handhelds as cognitive-behavioral aids, (2) onboard apps for task support, (3) add-on apps for task management, behavioral support, way-finding, and healthy living, and (4) strategies for leveraging these tools for people with cognitive-behavioral challenges to support functional independence in everyday life.
