Static tactile paving provides haptic cues to pedestrians through physical bumps in the form of raised dots and stripes, which are felt through the shoes indicating sidewalk orientation and intersections. FeetBack is a new form of active tactile paving that changes shape to direct people in public spaces. First, we present a qualitative study that guided the hardware development, design of actuation patterns, and identified the most recognizable patterns. Secondly, we conducted a quantitative study to measure the response time to directional haptic cues. All participants could easily recognize and respond to directional haptic cues in under one second, while directional responses added 150ms on average. We also tested whether similar results can be observed when participants' attention is divided while performing a reading task, however, we did not find any significant effect of this cognitive load on response time. We discuss the results in relation to other modalities and provide interaction scenarios and future research directions for active tactile paving and floor-based feedback. |
