Personalized Magic Mirror: Interactive Mirror Based on User Behavior

Abstract

Ubiquitous computing is changing our daily life with evolving devices. A mirror, which is one of our daily tools, is also showing its role changing to the instrument of information displayer. These evolving devices already have their own traditional roles and interaction methods. Therefore, one of the most important factors for the implementation of these devices is the interaction methods between devices and a user. Based on this point of view, this paper proposes an active digital mirror system which considers the relative position and interaction between a user and mirror. To implement our goal, we studied users’ behaviors and interactions on mirrors with user testing. There were four considered factors: the distance between a user and mirror, relative position of a user in front of a mirror, intuitive interaction method and personalized information. Based on the preliminary research, we designed the user interface of the mirror, and developed a prototype which has three recognition modules: a distance measuring module using infrared sensor arrays, a user recognition module by computer vision technique, and a control perception module using infrared sensor grid. In addition, the next steps for improving the user-centered digital mirror system, and the possibility for developing a mirror-shaped computer system were suggested.
