ABSTRACT:
A pair of devices is provided of similar construction. Each device includes a beam-splitter, a CRT for providing an image from the remote device and a TV camera to send an image to the remote device. The image from the CRT is viewable by a person using the device at all times. The TV camera will sense and send an image either of a person using the device or an item to be viewed. A pair of selectively operable light sources are provided to illuminate either the person or the item. If the person is illuminated, the TV camera transmits an image of the person. If the item is illuminated, the TV camera transmits an image of the item. A sound system is provided for audio communication. Computer means may be provided for controlling operation of the device.
