Mobile, networked, multi-sensory systems and technologies with open and modular interfaces are about to change our established concept of technical extensions for humans. Thus, it will not only be on the level of prosthesis or implants that humans are connected with machines, but as well on the level of wearable sensors and intelligent environments, which make interfaces disappear and allow “unmediated” contact between the human and the technological system. Departing from a notion of holistic bodily experience and media developed in current phenomenological approaches, we want to examine the affective human perception in a mediated responsive environment. By this, we aim to explore the connecting area between the human body and a sensitive environment that feels like it connects to the body as a “second skin”.
