Virtual graffiti consists of virtual or digital media applied to public locations, landmarks or surfaces. Virtual graffiti applications utilize augmented reality and ubiquitous computing to anchor virtual graffiti to physical landmarks or objects in the real world. The virtual content can then be viewed through digital devices. 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.
