Strike a pose: Directional cueing on the wrist and the effect of orientation
Résumé
Many wearable haptic devices have been developed for providing passive directional cues, in the form of belts or back displays but these systems have so far failed to make an impact in the public domain. One other potential solution is a light, discrete and aesthetically acceptable vibrotactile bracelet. However, contrary to these other systems, the wrist is subject to rotations, therefore a controversial locus for vibrotactile feedback in a navigational context. This paper presents a set of experiments aimed at both determining the basic feasibility of using this kind of bracelet and to examine to what extent the orientation of the user's wrist affects their perception of directional cues both in static and mobile conditions. It was found that changes in orientation have little negative effect overall, distraction being more of a concern.
