The aim of project REPLAY is to develop a gaming technology platform to provide young people who have become marginalised in society as a result of anti social behaviour with a learning environment to facilitate their reintegration into society. Although scalable to a range of marginalised groups such as immigrants, children with learning disabilities, retirees etc, REPLAY will focus on the rehabilitation of young people whose behaviour has become a problem for the communities in which they live.Interactive gaming technology is very popular amongst young people today and so the vision of REPLAY is to use this technology as a means of motivating young offenders into a better awareness of how and why they behave the way they do and encourage them to take greater responsibility for the consequences of their decisions and behaviour. The REPLAY solution will allow users to interact in a distributed gaming environment, share and exchange ideas, and cooperate in pursuit of common objectives. In this way, communication skills, the facility for mutual accountability and the ability to work in teams will be improved. Project REPLAY will prove that the concept of interactive gaming can be used to improve learning capabilities and provide users with an opportunity to "replay" their role in society following a dysfunctional start. The technology developed will provide users with a simulation in which they can learn by doing. Users will be able to implement decisions, observe and monitor the impact of their decisions in a given situation and learn from the experience. As such, the gaming environment will prepare young people for the challenges they will face as active and constructive contributors in society. Moreover, the technology will provide the social worker professional charged with monitoring their rehabilitation with a useful tool through which the rehabilitation process can be assessed and managed more effectively.
