A technique is provided for determining which pages of a selected magazine are read by a person acting as a test subject. Optic lenses are included which provide images of the magazine to a superimposing device. An image of the reader's eyes is also provided to the superimposing device so that the reader's eye movement is superimposed over the particular page being read. The superimposed optical signal is provided to a video camera which supplies it to a video monitor for real time observation as well as to a video recorder for later analysis.
