Fieldward and Pathward

Fieldward and Pathward are techniques for human-computer collaboration in designing user-defined gesture vocabularies on mobile devices. The user can interactively explore the continuous negative space of machine-recognisable but unused gestures with active feedback and feedforward provided by the system.  This enables users to freely create their own idiosyncratic gesture commands while maintaining adequate distance between gestures as defined by the gesture-recognition engine in use.

Abstract: Although users accomplish ever more tasks on touch-enabled mobile devices, gesture-based interaction remains limited and almost never customizable by users. Our goal is to help users create gestures that are both personally memorable and reliably recognized by a touch-enabled mobile device. We address these competing requirements with two dynamic guides that use progressive feedforward to interactively visualize the “negative space” of unused gestures: the Pathward technique suggests four possible completions to the current gesture, and the Fieldward technique uses color gradients to reveal optimal directions for creating recognizable gestures. We ran a two-part experiment in which 27 participants each created 42 personal gesture shortcuts on a smartphone, using Pathward, Fieldward or No Feedforward. The Fieldward technique best supported the most common user strategy, i.e. to create a memorable gesture first and then adapt it to be recognized by the system. Users preferred the Fieldward technique to Pathward or No Feedforward, and remembered gestures more easily when using the technique. Dynamic guides can help developers design novel gesture vocabularies and support users as they design custom gestures for mobile applications.
