The ‘Three Good Things’ (TGT), a structured journaling exercise, has shown great effect in helping improve mental well-being. However, the exercise could be quite tedious and difficult to carry out daily. To improve the user experience of the exercise, we developed ‘Happy Click’, a mobile application which makes use of a physically present smart button to enable users to record their daily TGT in a more engaging manner. Two preliminary exploratory studies were carried out to examine the feasibility of our approach where the effects of the TGT intervention designed around the mobile and tangible happy click concepts were examined. The findings suggested that participants had significantly less stress after carrying out the TGT using the tangible interface. Participants also reported better user experience and acceptance when carrying out the exercise using the tangible interface compared to the mobile and higher levels of attractiveness and stimulation with the mobile TGT compared to the traditional approach. While these promising results should be interpreted with caution due to the limited sample size, they also underscore the potential advantages of our ‘Happy click’ approach and highlight the need for further, larger-scale evaluations to be conducted to validate its efficacy and scalability.@en
