The quote from the reading, ‘Virtual Bodies‘, explains the disembodiment of the cyberspace perfectly: the movement from a physical presence to a concept. Take Facebook for example: in real life, a person is presented (for the most part) as their true self in their physical presence. However, upon entering the cyberspace, they are able to represent themselves as they please; one can edit photos to appear as desired and is able to take their time to craft an opinion or response before commenting on a post. In this sense, the Facebook profile is more of a concept of a person rather than a true physical representation of the person.
The telematic experiment, Telematic Vision, by Paul Sermon is an interactive installation, composed of two, identical blue couches in entirely separate locations, linked together by a monitor. The video images captured from each part of the installation are sent to a video mixer, combining the images onto the monitor before the persons, appearing as if the separate parties were on a singular couch, physically interacting with one another (bringing the virtual bodies into the third space). Participants (from both sides) react to one another by moving their bodies and physically interacting. Without this participation, the artwork or performance does not exist. Similar to the explanation of dance from the reading, this installation portrays a deep connection between performance and embodiment. However, the reading creates a dichotomy between physical presence and concept (as explained above by the example of Facebook). In Telematic Vision, it becomes holistic. Without the physical presence (participants sitting on the couch), there is no concept (the virtual presentation of the users in the third space, interacting on the monitor). These two notions (physical presence and concept) therefore become co-dependant.
I think it’s interesting that you recognized the idea that physical presence and concept are co-dependent. This is very true for the Telematic vision, since without the physical presence, the concept does not exist and no interaction can occur.
