Study, Perceptually Similar Visual Environment. Final Report.
King, Barry C.; And Others
A long-range investigation is being made to define the characteristics required of a television system to simulate a visual environment which will permit target acquisition performance comparable to that obtained in the real world. In this portion of the investigation, target recognition performance under direct viewing conditions was compared with performance under television-mediated viewing for a variety of static military targets. The use of a specially designed closed-circuit television system permitted video "signal-to-noise" to be treated as a carefully controlled parameter in order to assess the effects of noise on television-mediated recognition. It was found that when the image degrading effects of video noise are eliminated, the dominant factor in the determination of television-mediated target recognition appears to be the number of active scan lines per frame, rather than the systems' limiting horizontal resolution. Exploratory tests using the Martin Marietta Guidance Development Center three-dimensional terrain model suggest that a similar approach may be used to investigate target recognition under dynamic "real-world" conditions.
