Reflecting on positive moments in daily life can amplify emotions and improve well-being. In this study, we develop a life-logging service called TippyMirror, focusing on a display method using the mirror metaphor. TippyMirror helps people collect and reflect on their daily positive moments. This study compares TippyMirror with TippyVR-Plus, which uses Virtual Reality (VR) technology, from psychological and motivational perspectives, where previous studies have shown that VR technology has strong effects on emotions. The experiment showed that TippyMirror has similar effects to TippyVR-Plus in reducing negative emotions. While TippyVR-Plus was better at amplifying positive emotions, the introduction of a function focusing on individual positive moments indicates that TippyMirror can provide effects similar to TippyVR-Plus. For that, we found that a contact-less interaction method such as gaze-based interaction should be added to TippyMirror.
