This report gives a technical overview of the program logic and the architecture for the CitiTag game, a wireless location based game, developed by the Knowledge Media Institute's Centre for New Media in collaboration with HP Labs' Mobile Bristol team. CitiTag is a real-time multiplayer team game, played outdoors using GPS (Global Positioning System) and handheld, PocketPCs connected to a wireless network. CitiTag aims to encourage social experiences and group play in public spaces, based on the awareness of other peoples' presence.

Multimedia and Information Systems
Our research is centred around the theme of Multimedia Information Retrieval, ie, Video Search Engines, Image Databases, Spoken Document Retrieval, Music Retrieval, Query Languages and Query Mediation.

We focus on content-based information retrieval over a wide range of data spanning form unstructured text and unlabelled images over spoken documents and music to videos. This encompasses the modelling of human perception of relevance and similarity, the learning from user actions and the up-to-date presentation of information. Currently we are building a research version of an integrated multimedia information retrieval system MIR to be used as a research prototype. We aim for a system that understands the user's information need and successfully links it to the appropriate information sources, be it a report or a TV news clip. This work is guided by the vision that an automated knowledge extraction system ultimately empowers people making efficient use of information sources without the burden of filing data into specialised databases.
