Merian Scout Navigator - MWOW for cities

In a session at Where2.0 2008 Frog Design will talk about the device/software they developed to provide city information to tourists.

Link to Where2.0 session - " En route information alerts users to the sights around them, calling upon a wealth of images, media, and interactive maps"

Link to Scout Navigator device - "Calling this a sat nav system could be taken as insult since Merian also claims to be a personal travel assistant that features GPS audio guides, which automatically play when you pass by any one of more than 800 places of interest in Germany"

The Merian device comes close to the MWOW concept, except for the fact that (a) they built a device, and (b) there's no mention of crowdsourced information.
