Improvement Design of Smart Toilet Interactions Based on Peak-End Rule

Technology is recognized as a vital measure to promote the transformation and the upgrading of medical industry when health management has entered the intelligent era. Smart toilets, considered to have great potential for monitoring health information at home, emerge in our daily life. This paper is conducted to ameliorate the key interactions between human and smart toilet and based on peak-end rule, effectively improving user experience. A new design approach is applied to finds the peak and end moments in using process, and finally identifies four key interactions through the method combining user interview and Kano model. This paper details how the application of the new approach improves the interactions between human and smart toilet, contributing to a smoother product operation process which creates a better user experience.
