Today, I looked at a research paper from 2007 entitled A context-aware mobile mash-up platform for ubiquitous web. As the title indicates, these researchers sought to create a mobile application platform that supported context-aware features in what is known as the Ubiquitous Web. Context-awareness was achieved by a combination of features, including precise location (GPS), proximity (Bluetooth), an object's physical features, and user-generated annotations (i.e. keywords/phrases). Ubiquitous Web (or UW) is an idea that enhances the context-awareness; it involves linking physical objects to a virtual resource via URIs and then providing information and services that enrich the user experience.
The specific platform they envisioned and implemented was known as Sentient Graffiti (or SG). The flow of information in this platform is described in the image below. Essentially, users can divide the functional blocks of SG into two layers. Graffiti annotation involves the placement of content using the context-aware properties mentioned previously, and graffiti discovery/consumption is the browsing of those pieces of content.

The researchers insisted that SG is a platform and not an application because of its ability to be used to create other context-aware applications. They claim that SG addresses three critical functional requirements for these types of apps: the modeling of every physical object/region, the filtering of annotations by context, and the pool of HTTP push/pull commands for user interaction. The paper closed with a few examples of how SG could be used, one of which is pictured below.

Thanks and gig 'em!
