This paper introduces an approach for implementing context-sensitive user-centered scalability (CSUCS) into interactive applications using motion recognition. With scalability we refer to a system’s ability to adapt to the physical and cognitive abilities of a specific user. We discuss an adapted HAAT-model (Human Activity Assistive Technology Model) and the flow concept and show their use in two prototypical implementations: An “exergame” enriching sports exercises for the elderly and an assistive system using gamification elements to enrich the working experience of impaired and elderly persons.

Both systems have in common that they use motion detection and mechanics from game design (gamification). They transparently adapt to and visualize the users’ performance. The real-time analysis of the users’ movements is a prerequisite for the successful implementations of CSUCS.
