Abstract

Real-time computer graphics and complex sensory input challenge past assumptions of highly constrained metaphors based on static imagery. Access to research and gaming interfaces have popularized the understanding of tracking technologies that tailor interaction to ambulatory displacement and dexterous handling of objects, expanding the realm of metaphors from visual to physical phenomena. But behaviour and the mind have been studied far before there were real-time computer graphics or digitally created synthetic environments. Dynamic relationships between environment, body and thought are being dissected today by neuro-scientific research, and, conversely, synthetic environments are being utilized to address psychological disorders. This article examines research on scientific and philosophical fields that advance the definition of representation, from an image-based realm as limited by previous popular media to an understanding of action and immersion, where attention is activated by change, and rooted in the body. From this perspective, the advent of embodied representation may not be as much of a change of medium, but the perceptual relation with the medium, the medium being a created Umwelt, where the virtual world builds the mind through the body.
