Augmenting User-Maintained Interaction Through Mode Locking and Reversing

Abstract

User-maintained mode is often adopted in facilitating a bimanual interaction using multitouch devices, in which a thumb of a non-dominant hand holding the device can press a part of the screen and keep pressed in order to activate and maintain a temporary mode that is required only for a short period of time, until the user releases the thumb. In this paper, we characterise this particular interactivity and propose novel locking mechanism that supports easy swapping between primary and secondary modes enabling further useful bimanual interaction mechanism that we call reversed mode relationship. We design three prototypes that employ this interactivity and conduct a usability testing with 27 participants. Findings suggest that this interaction works better in applications where there are frequent but short and non-intensive sub-tasks that interrupt the main workflow. We use this insight to further explore more advanced ways to support such interaction.
