Other researchers have started to investigate the potential for the use of ambient persuasion, in which visual feedback about physical activity levels is presented peripherally – e.g. through an augmented mirror\footnote{A technology that uses a one-way mirror to achieve an intuitive augmented reality environment} \cite{FujinamiRiekki08} or using tablet-based information visualisation methods \cite{fan2012}.  Feedback is the most important element in In  all the physical activity monitoring devices discussed technologies reviewed  in this paper.   Goal-setting paper, feedback either through a visual or a music/haptic display has been present and has shaped a significant part of the choice architecture depending on the negative or positive nature of the feedback. In the other hand, goal-setting  is rarely used as a standalone motivational tool. More commonly, it is framed within the context of games \cite{Ahtinenetal10,Berkovskyetal09a,Gasseretal06,Linetal06} or social awareness applications \cite{Consolvoetal06,Toscosetal08} that explicitly introduce aspects of teamwork, competition and social facilitation into the process of behavioural change.
