Measurements were made of subjects' head movements as they found and memorized the
position of targets located around them. Four factors were manipulated: the size of the field …

Seventeen subjects searched for, and then monitored, 3, 6, or 9 stationary targets in order to
detect and shoot 3 threats. The targets were located in an area 1200 left and right and 900 …

Measurements were made of the ability of 20 subjects to acquire 3, 6 or 9 stationary visual
targets and then replace them after they had been removed. The targets were viewed with …

Two experiments were conducted to determine the human's ability to acquire and memorize
the spatial locations of stimulus targets using a helmet-mounted display. The experimental …

Seventeen subjects were presented with stationary targets at random locations in an area
120 left and right and 90 deg upwards from straight ahead. Targets would change shape to …

Ten subjects performed a task on a head-coupled simulator using various sized fields-of-
view (FOVs). The task required them to visually acquire, remember the location of, monitor …

Experiments have been conducted on human subjects to assess the efficiency with which a
helmet-mounted sighting system can be used to locate and track target sources in the …

Pilots using a single-eye helmet-mounted display (HMD) for night vision have orientation
problems that are strongly affected by head movement. However, it is precisely this behavior …

Human subjects localized a monocularly viewed, space-stabilized virtual object presented
on a head-mounted, see-through display. They either kept their head stationary or rocked it …

The head-mounted display (HMD) is a popular form of virtual display due to its ability to
immerse users visually in virtual environments (VEs). Unfortunately, the user's virtual …
