Multimodal Interaction for Pedestrians

What are the most suitable interaction paradigms for navigational and informative tasks for pedestrians? Is there an influence of social and situational context on multimodal interaction?

A new study takes a closer look at a multimodal system on a handheld device that was recently developed as a prototype for mobile navigation assistance. The system allows visitors of a city to navigate, to get information on sights, and to use and manipulate map information. In an outdoor evaluation, we studied the usability of such a system on site. The study yields insight about how multimodality can enhance the usability of hand-held devices with their future services. The study show, for example that for our more complicated tasks multimodal interaction is superior to classical unimodal interaction.
