Abstract: 

Bend gestures offer a rich interaction language for flexible displays due to their large degrees of freedom. However, without an understandable visual feedback system, working with such interaction could be a difficult challenge for users. In this thesis, we have developed three visual feedback systems by using feedforward and feedback mechanisms with the goal of guiding users to correctly perform bend gestures on a handheld flexible display. Additionally, we have conducted an experiment containing two tasks, which, using a flexible prototype, evaluate the usefulness of our visual feedback designs. Our results suggested that users could perform sets of bend gestures faster when the visual feedbacks appear at the exact location of the bend gesture instead of always at a fixed location on the screen.we found that, while feedforward improved users’ performance, using feedback had a negative effect. Finally, we propose a set of design guidelines for designing visual feedback systems.
