Abstract

Difficulties are often associated with perceiving tactile feedback from a mobile device while ambulatory. In this paper, we describe a study conducted using multi-parameter tactile icons (tactons) with a view to identifying designs to better resist the masking effects associated with walking. Our findings suggest that tactons encoded with longer durations (800ms) or those with stronger intensities (Amplitude: 2.1g Frequency: 255Hz) offer promise to individuals on-the-move. In terms of future work, we aim to identify ways to reduce the recognition time and the levels of cognitive workload experienced when resolving multi-parameter tactons, to augment the human-mobile interaction experience.
