Towards Effective Interventive Health Applications: On the Problem of User Triggering
Extensive studies show that regular physical activity is one of the crucial factors to determine one’s prolonged health and wellbeing. But although this knowledge is fairly widespread, many people still fail to meet the WHO recommendations for the weekly average of physical activity. While the reasons for this shortcoming are manifold, a lack of motivation on the one hand and a lack of awareness on the other may be considered to be the two main culprits. Interventive fitness and health applications, being both pervasive and persuasive, may help to counteract this problem by assisting the user during her daily routine in finding both the required motivation and good opportunities for being physically active. This contribution focuses on one of the main challenges of such applications, namely the identification of situations which are suited for notifying (“triggering”) the user of a chance for physical activity.
