"This concept assumes that the center of the projection is capable of perceiving from the point of view of the location in space to which it has projected itself - rather than from the subject's actual eye-level. "We have now contacted over 100 individuals who responded to our appeals for participants. Out-of-town subjects were invited to project themselves to my office and try to identify target objects arranged on a coffee table there. Several people obtained very encouraging results. "Our major subject to date has been Ingo Swann, with whom Janet Mitchell has conducted exploratory sessions. "The general procedure has been as follows: Mr. Swann sits quietly in a semi-dark experimental room, attached to a polygraph (in the adjoining room) which records data concerning his physiological state, i.e., brain waves (EEG), heart rate, respiration, etc. "The targets are on a shelf suspended two feet from the ceiling of the experimental room. This shelf is divided by a partition, on each side of which is a tray containing an arrangement of target objects, placed so as to look distinctively different as seen, say, from the south or from the north.
