Social Comparison in Behavior Change Support Systems: Heuristic Evaluation of a System's Usability

People’s willingness for sharing personal data with others allows designers to consider utilizing social comparison functions into behavior change support systems. Behavior change applications, which enable social comparison, seem to be gaining popularity nowadays. Usability flaws may diminish the usage and engagement of behavior change support systems, therefore attention was paid to usability issues in this particular case. Following usability guidelines early enough in the design may save time and resources.
