This is a mobile application that can help people heal and regulate chain negative emotions. As we all know, bad emotions will affect people’s physical and mental health, especially bringing negative emotions into life will cause a vicious cycle of bad state. App helps users produce positive psychological changes in a fun and relaxing training method. In my design, we can see different strategies for healing emotions. The ‘Strategic Formula’ represents professional periodic psychological planning, and the ‘Timely Formula’ recommends interesting cures through daily emotional data. Interactive game design plays a very important role in my program, such as ‘AR’ function and ‘The world’ function of entertainment, reminding people not to forget to gain the power of calm even during the chaotic epidemic. The design of this interactive function also inspired me to explore the methodology of emotional design.
