The "InteractiveBody 4.0" is an intensive workshop focuses on the interaction between human and immersive spatial environment. Unlike the normal so-called interactive architectures nowadays which consider responsive as interaction, the workshop would like to push the notion of interactivity a bit further. In other words, the workshop proposes an innovative interactive space as a living creature which has emotions and abilities to react. The crucial questions, such as, how this spatial creature reacts? What is its' motions respond to the human involved in? When and what kind of new relationship between space and human will establish? should be explored and attempt to answer through the workshop. The workshop also tries to reverse the conventional spatial notion of static and passive environment into dynamic and aggressive surroundings. A space with "Pro-activeness" will take place in such a condition.
