Face-to-Face 4 Figure 1 illustrates the installation Face-to-Face 4 as it was set up in September 1989 for the (Tele) Communicatie in Kunst events at the V2 Center, 's Hertogenbosch, Holland. Two people interact between spaces A and B. Though they are separated visually by a vertical barrier, they can hear each other around or over it. They also can touch each other, or pass an object to one another, if one of them moves 9 ft through the space that separates them. Both participants have equal control in that they have access to each other's space. When communications technology is introduced into spaces A and B (as shown in Fig. 1), it enables the two participants to be together visually-through television (TV) monitors-while remaining physically separate. The basic equipment required is minimal, user-friendly and readily available: two cameras and four TV monitors, with connecting cables. Each participant faces a camera and a TV monitor. The camera in space A is connected to the TV monitor in space B, and vice versa. The video-out signals from these two TV monitors are sent via cable to the second pair of TV monitors located in space E and placed 11/2 to 2 ft apart, facing each other. In this case, space E is located just behind a wall that is perpendicular to the visual barrier separating the two participants. To the spectators, who are free to move around spaces A, B and E, it appears as though the two TV monitors in space E are 'talking to each other', as participants in spaces A and B are talking to each other (Fig. 2). This is a 'talking-heads' situation in which the public can participate by entering the electronic space created between spaces A and B. This electronic space gives the two participants on either side of the barrier visual access to one another without one of them having to move through space.
