Serious Games for Physical Rehabilitation Designing Highly Configurable and Adaptable Games Department of Electronics and Informatics (ETRO), Vrije Universiteit Brussel

Rehabilitation process Boring and repetitive exercises Inability of children to challenge themselves Lack of motivation Serious games are a promising tool to increase motivation, challenge and fun

Serious games Lack of modern computer games for the physical rehabilitation and exercises Existing games – are often one purpose only or are aimed only for a specific exercise – have limited configuration possibilities – do not provide any runtime analysis or evaluation of the exercise

Proposed gaming platform Based on the concept of mini-games Universal input interfaces – Any game can be controlled with any input device – 3D Cameras, Balance boards, Accelerometers, but even not standardized devices you have Increases the configuration possibilities – Sensitivity, Zero (neutral) position – Easy visual configuration even for non-technicians
