The basic purpose of this experiment was to compare head |
|
tracking performance at various angles from the straight |
|
ahead position. In our previous laboratory studies (e.g. |
|
Shirachi and Black, 1975; Hornseth, Stanley, and Carson, |
|
1976; and Shirachi, Monk, and Black, 1976) head tracking |
|
was performed within a + or - 15 deg or less cone about |
|
the straight ahead or boresight position. Honeywell has |
|
conducted studies in which the subjects aimed their heads |
|
as far off boresight as 40 deg (Hughes, et al, 1970). |
|
Their subjects slewed their heads in the direction |
|
indicated by an arrow, on the head position display they |
|
were using, until a target came into the field of view of |
|
the helmet mounted display. At this point their task |
|
became that of laying a reticle over the target to |
|
achieve lock on. The length of time the subjects were |
|
actually tracking was only a few seconds. Flight test |
|
studies conducted at Tyndall AFB and China Lake (Dietz, |
|
et al, 1971 and Grossman, 1974) investigated head |
|
tracking performance which included large off-boresight |
|
angles. The target motion in these two studies was highly |
|
predictable. |
