The potential to increase physical activity with computer-tailored intervention techniques has been acknowledged, but due to low adherence rates more research is needed to identify successful mechanisms that promote physical activity over the long term. Due to the threat of disease prevalence and related health care costs it is important to develop an efficient method that is durable over the long term and has a high adherence rate.

It is possible that people can be socially influenced through social networks to achieve and maintain a healthy lifestyle by sharing related opinions, emotions and behaviour that affect lifestyle behaviour. This influence can spread within a social network by social contagion. The effect of social contagion on young adults has been studied and indicates that it could possibly be used in an effective intervention.

The aim of this study is to design different visual representations in which information about physical activity of other people can be shown. The purpose of showing these visual representations is to alter connection strengths between people which in turn should affect the social influence that is spread throughout a social network. These representations will be tested and validated in an experiment to indicate its effectiveness and gain more insight in the effect of social contagion.
