Virtual graffiti

Virtual graffiti is aimed at delivering messaging and social multimedia content to mobile applications and devices based on the identity, location, and community of the user.

[2] In this system, the buildings are selected on a map, and the graffiti is stored in a database that can be accessed from other mobile devices and the project’s website.

A location-based messaging system[3] for leaving virtual post-it notes on physical objects was developed at the National University of Singapore.

The system uses mobile devices as Augmented Reality interfaces to view virtual messages associated with fiducial markers on physical objects.

In a project from Lancaster University,[4] mobile phones are used as digital mediums, using RFID tags to identify markable objects.
