Located at the SK Telecom headquarters in Seoul, South Korea, the T.um exhibits the essence of future communication technology. It demonstrates a new possibility of future space design experience by defining ubiquitous environments with virtual and actual spaces such as “Smart Space”. Breaking away from traditional one-way viewing, visitors can truly engage in the T.um experience through the digital avatar “T.me”, which utilises user loca-tion tracking technologies to guide its owner. T.me evolves by learning selective behaviours and experiences of visitors and their communication with each other while compiling information to its database. Also, a flow of LCD displays called “Media Floor” and mirrored ceilings which reflect the floor symbolise the combination of actual and virtual space.
