User Perspectives on Multi-touch Tabletop TherapyMichelle Annett, Fraser Anderson, and Walter BischofDepartment of Computing ScienceUniversity of Alberta, Canada
+Stroke rehabilitation
Many people suffer loss of upper motor ability following a stroke
To regain function, therapists encourage repetitive movements to increase muscle strength, coordination, and range of motion
These activities are often monotonous and discouraging, causing patients to neglect their treatment
+Technology to the rescue
In recent years, technology has been used to improve stroke rehabilitation Gamification of repetitive movements to increase
engagement Use of technology allows customization, progress
monitoring, and feedback
Previous research shows no intrinsic movement benefits to technology Power is in enjoyment, customization
+Tabletop therapy
Interactive tabletops have several benefits Direct interaction Large, 2D interaction space Ergonomics (supports body
weight, allows seated interaction)
Challenges User’s expectations
increase with commercial products
Direct interaction leaves little room for error
+Study
14 healthy subjects (7 male, 18-77 y)
Performed 4 tasks (2 tech, 2 traditional)
Completed questionnaire (Intrinsic Motivation Inventory)
Semi-structured interview
+Lessons Learned I
People enjoyed: Interactivity Animations Sounds Feeling of accomplishment, competition with themselves
+Lessons Learned II
User Expectations P13 notes “if you have an iPad you
can see that it registers every motion and gesture ... the design of [iPad] games are better”
And P12 is “just so used to playing those iPhone games”
Frustration and Responsiveness P7 was “irritated at how the
tabletop wasn’t too responsive” P8 “felt [they] could handle the
physical materials more easily than the digital ones”
+Takeaways
Provide immediate feedback on their actions
User-facing aspects cannot be ignored Patients may already be discouraged by
the nature of the activities Small frustrations can negate many
benefits of technology
User expectations will continue to increase Older users currently not familiar with
technology, but this will change, and expectations will be higher
