This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 1 November 2010, is one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It proposes a provisional cockpit design for craft driven by speculative breakthrough propulsion, such as control of gravity and inertia and faster-than-light travel. It draws mainly on the book Frontiers of Propulsion Science and on human-machine interface research.
UNCLASSIFIED/ /P9Pl 8ffllil.t.k WE'lii ODIi Y Fields of View There is a difference between what humans are physically capable of seeing and where they naturally concentrate their attention. Using a reference point that is straight ahead and level with the eyes, the normal full field of view extends laterally (left/right) ±100°, upward about +60°, and downward about -75°. Of course, turning the head can extend the lateral reach directly behind, but that rearward view would be in the edge of periphery vision. This full span, however, is not where humans normally direct their attention. With the head in a fixed position, the normal field of view spans left/right ±100°. The periphery is most sensitive to motion even when discrete images cannot be resolved. The region shown that spans roughly ±60° is the area that can be easily scanned by moving the eyes and whose information can be mentally processed in parallel. A much narrower field, about ±6 °, is where humans can discern details and begin processing information serially. This zone can be aimed anywhere in the normal field of view. Finally, the region of focus where alphanumerics can be read is only about ±2 °, which corresponds to only one square inch at a distance of 2 feet. Another characteristic of human vision is the tendency to fixate in the upper right corner of a given display. In the figure insert, the percentages shown refer to the proportion of total time that the eye tends to fixate on those regions. Normal field of view Area of easy eye motion scanning / Figure 9.
