Pedestrian navigation system implications on visualization

Abstract

With the technical advances in mobile computing electronic maps and guiding systems become widely available for everywhere usage. The computing power allows for guides and even decision support systems. But mobile devices are used on the move and therefore become a secondary task. To reduce cognitive load and to reduce attention intensity visualizations and interaction patterns are needed that are fast and comprehensible. We present a pedestrian navigation system that uses a zoomable interface together with me Halo visualization approach for off screen locations. A user trial with 24 participants indicate that this approach reduces the device interaction immensely leaving more attention to the primary task. © Springer-Verlag Berlin Heidelberg 2007.
