An exhibition, called “Mirror or Mirror,” displaying the integration of fashion design and technology took place at Dongdaemun Design Plaza (DDP) in Seoul from July 18-25, 2015. DDP is the center of Korea’s fashion hub. The exhibition was created by Professor Daniel Pieter Saakes of the Industrial Design Department at KAIST and introduced a new design system reinforced with an interactive technology that incorporates augmented reality into the design process. Users stand before the Mirror or Mirror system, and by using augmented reality, they can design their own fashion items including clothes based on their need and fashion preferences. The augmented reality allows users to draw their favorite patterns or new designs over their body, thereby enabling them to check the result immediately and try out a variety of different designs right away. Professor Saakes said, “Fashion has always been a way to express individual and personal style. With our system, people can easily fulfill such desires, customizing their own designs.” At the exhibition, visitors also had opportunities to produce their own shirts while using the Mirror or Mirror system.
