"An operators' sense of remote presence during teleoperation or use of virtual environment interfaces is analyzed as to what characteristics it should have to qualify it as an explanatory scientific construct. But the implicit goal of designing virtual environment interfaces to maximize presence is itself questioned in a second section in which examples of human—machine interfaces beneficially designed to avoid a strong sense of egocentric presence are cited. In conclusion, it is argued that the design of a teleoperation or virtual environment system should generally focus on the efficient communication of causal interaction. In this view the sense of presence, that is of actually being at the simulated or remote workplace, is an epiphenomena of secondary importance for design."
Questions the need to design VEs for presence in all cases of teleoperation.

NB. The paper is badly written and the English is often such that the meaning is ambiguous or even lacking.

p.248   "A clear meaning for virtual as used in this paper may be based on a more general concept: virtualization, which can be considered the process by which a viewer interprets patterned sensory impressions to represent objects in an environment other than that from which the impressions physically originate."   Added by: Mark Grimshaw-Aagaard

pp.248-249   "one could consider the normal functioning of the human sensory systems as the special case in which the detection of physical energy and the interpretation of patterned sensory impressions result in the perception of real objects in the surrounding physical environment. In this respect perception of the physical environment resolves to the case in which through a process of systematic doubt, it is impossible for an observer to refute the hypothesis that the apparent source of sensory stimulus is indeed its physical source."   Added by: Mark Grimshaw-Aagaard

p.249   "As more and more sources of sensory information and envrionmental control are available, the process of virtualization  [...] can be more and more complete until the resulting impression is indistinguishable from physical reality"   Added by: Mark Grimshaw-Aagaard
