A communication system for allowing a user ( 1 ) located in an observation zone to communicate with a person using a remote system at a remote location is provided. The communication system comprises a projector ( 6 ), a front projection screen ( 7 ), a two-way mirror ( 2 ), and a camera ( 3 ). The projector ( 6 ) is adapted to output a projected image along an image beam path. The front projection screen ( 7 ) has a downward-facing projection surface located in a plane above the projector ( 6 ). The image beam path impinges upon and illuminates the downward-facing projection surface of the screen ( 7 ) during use of the system. The two-way mirror ( 2 ) is located adjacent to and at an angle relative to the projection surface such that when the projected image is displayed on the projection surface, the projected image is reflected to the observation zone. The camera ( 3 ) is located behind the two-way mirror ( 2 ), such that the two-way mirror ( 2 ) is located between the camera ( 3 ) and the observation zone.
