Behavior-Change Technology and Physical Activity

The main objective of this project is to study human motivation through the lens of Self-Determination theory. We aim at developing design guidelines to inform the development of apps and services aiming at supporting users towards a healthier lifestyle. We will conduct several experiments to measure the effectiveness of a diverse range of technological interventions in increasing physical activity.

Agon App is the latest study where we tested different combinations of Basic Psychological Need Features. This study brought inspiring results with respect to which feature combination increased the physical activity of our participants.
