Abstract: A technique for surveying an audience. A portable signal detector unit picks up audible sounds reproduced by a radio set from signals transmitted by a given radio station. Among the broadcast signals is one unique to that particular station. The unit includes means capable of identifying that signal to automatically electronically record the fact that the station is being listened to by the carrier of the unit.

Abstract: A technique is provided for monitoring the viewing habits of individuals in selected households. A stationary monitoring unit is provided which cooperates with a portable monitoring unit designed to be worn on the head of the individuals in such household. The stationary monitoring unit includes a transmitter for emitting an activating signal to a receiver on the portable monitoring unit. Such receiver senses the emitted activating signal only if the individual wearing it is looking at the television set. When the activating signal is sensed, it is used to activate a transmitter which emits a signal uniquely identifying the individual wearing it. This signal is emitted to stationary monitoring unit which includes circuitry for recognizing it and storing it in a recorder for later retrieval and analysis.

Abstract: A technique is provided for entering certain information into a computer without the use of hands. A touch screen system which utilizes a grid of light beams across a display surface is modified. Instead of interrupting the light beam with the operator's finger, light blocking devices are moved into position along the periphery of the surface to shield a light detector at the position where otherwise such detector would be blocked by the operator's finger. The light-blocking device is moved by motors under foot control. In another approach, indicator arrays are placed along adjacent sides of a display surface. One indicator along each side is lit by foot control to represent a selected position. In still another approach, a cursor is selectively positioned on the display surface with foot-operated control circuitry. Once a position is selected, further inputs can be made even with the use of another, hand-operated, technique in a convenient, user friendly and prompt manner.

Abstract: 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.

Abstract: A technique is provided for providing accurate information regarding the readership of certain magazines. A transmitter unit is attached to the magazines of interest and emits a signal unique to that particular magazine. A receiver unit is worn by individuals who have been selected as test subjects. The transmitter unit can detect the emitted signal only when it is within approximately one foot from the magazine. The receiver unit includes circuitry responsive only to the particular signal emitted by the transmitter in the magazine. When that signal is received, information is stored in memory regarding the occurrence of exposure of the magazine to the individual test subject and/or the time period of exposure. Information stored in that memory is then retrieved for analysis.

Abstract: A technique is disclosed for monitoring the eye movements of a subject with apparatus that is removably attachable to the subject's own eyeglass frame. The apparatus includes a light source to bounce light off the subject's eye and a detector to sense the reflected light. Both are adjustably mounted on a support. The support includes several interlinked parts which are readily adjustable to fit the subject's eyeglass frame.

Abstract: A device is provided which is specifically adapted to be removably secured to an eyeglass frame as it is worn by a person. The device can be aimed so that an optic system carried by the device will detect the scene being viewed by the wearer.

Abstract: A technique is disclosed for testing the effectiveness of a television commercial before it is broadcast. The commercial is displayed to a test subject in a realistic setting which includes a choice of programs from which he can select. The reactions of the test subject in selecting from among the various programs and commercials available to him are monitored and analyzed.

Abstract: A survey method and apparatus for monitoring visual observation of a transitionally viewed display. The procedure includes transmitting infrared radiation from behind the display and directed at the path of travel of a moving observer. A radiation detector receives reflected radiation and generates a thermal image corresponding to radiance variations. Retinal eye reflection from the observer is readily distinguishable in the thermal image and provides a positive indication that the observer's line of sight is vectored upon the display.

Abstract: A technique is disclosed to provide eye movement measurement in which the eye position signal is corrected for head movement. A reference point and reference point monitor means are provided one of which is fixed relative to the viewer's head and the other is fixed relative to the screen. An error signal is generated when movement of the reference point is sensed by the reference point monitor means. The error signal is combined with the eye movement measurement signal to obtain a corrected reading. This technique is usable with eye movement monitoring equipment which is of the head-mounted type and that which is of the stationary type.

Abstract: An autofocus system is provided for facilitating the focusing of a camera. An autofocus device is tiltably mounted on the camera body. Its position is controlled by an eye-movement-monitoring apparatus responsive to movements of the cameraman's eyes. As the cameraman shifts the position of his eyes, the autofocus device is controlled to move accordingly so it is aimed at the same portion of the scene viewed by the cameraman. The autofocus device then suitably controls the lens focus.

Abstract: A screening method and apparatus suitable for diagnosing dyslexia which includes a television camera for detecting reflected light to track eye movements in response to projected visual stimuli. The loci of said eye movements are superimposed over the visual stimuli on a TV monitor and also recorded. In addition, corresponding brain wave activity can be scanned and correlated with the eye movements.

Abstract: An apparatus is disclosed for testing the eye movements of a viewer in response to visual stimuli, such as an advertisement, displayed on a screen. One camera cooperates with a light source to detect eye movements indicated by a light beam deflected off the viewer's cornea. Another camera is placed parallel to the screen and in front of the viewer. A right-angle lens directs light from the screen into the camera. The outputs of the two cameras are combined to superimpose the viewer's eye movements on the images displayed on the screen. A running time starting with the instant the advertisement is exposed to the viewer is also combined with the eye movement and screen presentations.
