Abstract

We aim to contribute to the development of tactile-based pedestrian navigation systems that help users to navigate urban environments with minimal attention to the user-device interface. This paper describes the design and evaluation of a prototype and reports findings from (i) a lab-based study that directly compared features of two widely researched forms of tactile display: a waist belt and a back array; and (ii) a field evaluation which compared our prototype tactile-based navigation system (TactNav) with a visual mobile maps application (Nokia Maps™). Lab results indicated that the waist belt afforded significantly better performance than the back array across a wide range of metrics. Field results indicated that users' performance with the tactile-based system was equivalent to that with the visual-based system in terms of accuracy while route completion time was significantly faster with the tactile-based directional display.
