PUNCTUM

Punctum is a mobile app that uses the gesture of pointing out objects in the physical environment to interact with their digital information. By overlaying three-dimensional virtual models with their related elements in the real world, it's possible to browse buildings and other volumetric elements in a seamless experience... On server-side, Punctum integrates OpenStreetMap's volumetric georeferenced data and Wikipedia's complementary information, so, after identifying the object of interest in the real world, all public and colaborative information about it is sent back to the app and displayed to the user.
