>Visual aid for navigation – using human image processing

>While browsing the equator website I came again across an interesting publication – I had seen two years ago at MobileHCI – in the domain of pedestrian navigation [1]. The Basic idea is to use a collection of geo-tagged photos to provide visual cues to people in what direction they should go, e.g. “walk towards this building”. This is an interesting application linking two concepts we discussed in the part on location in my lecture on pervasive computing. It follows the approach of augmenting the user in a way that the user does what he does well (e.g. matching visual images) and the computer what it does well (e.g. acquiring GPS location, finding pictures related to a location in a DB).
