The Treasure Hunt demonstrator was developed as a proof of concept application, showing how to combine mobile technology and location information to create a unique learning environment. The application is based on the well known children’s game of a treasure hunt, but using XDA-II PDAs and IR tags by a company Hypertag Ltd. The players split into competing teams with have a ‘home’ and ‘away’ contingent.
In the initial study, conducted with mixed groups of teachers and children, the home part of each team was seated at a networked pc, whilst the away team members searched around the buildings and grounds of Robinson Executive College in Cambridge.
The teams were looking for tags which would fire off clues in the PDA and that (when solved, with the aid of the home team) lead to the next tag - and ultimately to a prize. The workshop had five competing teams running around searching for clues. Each tag gave exclusively different clues to different teams, so there could be no cheating or following! And each treasure trail was different for them all... with a mix of geographical, mathematical and general clues leading to the next location.
The tags used were produced by a company called Hypertag - being IR devices they can easily work with the IR interfaces of smartphones, like the XDA. So whilst they can show the potential of RFID like devices - they can be used right now, to get the exploratory models right!

Knowledge Hunter is a further development on the principles of the Treasure Hunt game discussed previously. Once again it combines mobile technology and location information to create a unique learning environment.
The location information in this case is provided by RFID tags, which have the added advantage of not requiring a line-of-sight and requiring no connected power supply. This simple example uses a 'mobile' game that involves answering a question to get directions to the next location in the game, until all locations have been visited. At each site visited a unique RFID tag triggers the question for that location and instructions for the next task in the game.

The Knowledge Hunter application is available for download, for Prolearn members to run their own games, and is available as a demonstrator from the link below:

CitiTag is a wireless location-based multiplayer game, designed to enhance spontaneous social interaction and novel experiences in city environments by integrating virtual presence with physical.
The game was developed as a collaborative project between the Open University and Hewlett Packard Labs, Bristol. In the first version of CitiTag you roam the city with a GPS and WiFi-enabled iPaq PocketPC in search for players of the opposite team that you can ‘tag’. You can also get tagged yourself if one of them gets close to you. Then you need to find a friend to free you. Urban space becomes a playground and everyone is a suspect.

The RAFT project (Remote Accessible Field Trips) is aimed at facilitating field trips for schools, but the concepts of using technologies to support remote learning interactions in the field are also relevant to professionals. The RAFT system includes work by Prolearn Partners in FIT, and by associate partners at the University of Dundee.

In a similar vein, work on connecting experimental devices to mobile users on PDAs is presented by the Automatic Control Laboratory hosted by EPFL. This work aims to showcase Real-time Interaction over the Internet to enable users to efficiently interact with physical equipment at a distance.
