Calhoun, Gloria L. and Janson, William P. (1990): Eye and Head Response as Indicators of Attention Cue Effectiveness. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 1-5.

“This study examined whether eye and head responses can be used to evaluate attention cue effectiveness. The subjects' tasks were to complete a centrally-located tracking task while periodically responding to cues to identify targets at four peripheral locations. Five directional cues were evaluated: visual symbol, coded sound, speech cue, three dimensional (3-D) sound and 3-D speech (the 3-D cues appeared to emanate from the peripheral locations). The results showed significant performance differences in eye and head reaction time, as well as peripheral target task completion time, as a function of cue modality. Since these relatively nonobtrusive measures were as sensitive to cue modality as the peripheral task completion time, these results suggest that eye and head reaction time can be used in evaluations addressing the effectiveness of attention cues.”

Calhoun, Gloria L., Janson, William P. and Valencia, German (1988): Effectiveness of Three-Dimensional Auditory Directional Cues. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 68-72.

“Natural aural directional cueing in the cockpit should relieve the demands placed on the visual modality, reduce display clutter and alleviate cognitive attention needed to process and extract meaning from coded formats. This experiment compared the effectiveness of three-dimensional (3-D) auditory cues to conventional visual and auditory methods of directing visual attention to peripheral targets. Five directional cues were evaluated: visual symbols, coded aural tone, speech cue, 3-D tone (white noise appearing to emanate from peripheral locations) and 3-D speech (speech cue appearing to emanate from peripheral locations). The results showed significant performance differences as a function of directional cue type in peripheral target task completion time, as well as eye and head reaction time. Results, such as these, will help improve the application of directional sound in operational cockpits.”

Janson, William P. and Calhoun, Gloria L. (1988): Latencies of the Eye and Head to Targets in the Vertical and Horizontal Planes. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1424-1428.

“Past studies involving oculomotor responses have typically been limited to refixations along the horizontal plane, small samples sizes, and little data pertaining to head movement. The study reported herein addresses these data voids by collecting both eye and head latency data for refixations in the horizontal and vertical planes. The subjects' task was to perform a central manual tracking task while periodically responding to a verbal command to classify a target on one of four peripheral monitors. Two targets were displayed along the horizontal plane and two along the vertical plane. Results from 620 trials indicated similar trends for the eye and head latency across all four monitor locations, suggesting no significant differences in eye or head latency as a function of target plane.”

Janson, William P., Quam, David L. and Calhoun, Gloria L. (1987): Eye and Head Displacement to Targets Fixated in the Vertical and Horizontal Planes. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 243-247.

“While the nature of the eye and head displacements to target acquisitions in the horizontal plane have been frequently studied, such investigations in the vertical plane are somewhat scarce. In the experiment reported herein the final displacements of the head, eye, and gaze were examined for target acquisitions in the vertical and horizontal planes. The subjects' task was to fixate on a central target until receiving a verbal command to fixate on one of four peripheral targets. The analysis of the mean head, eye, and gaze displacement data to the target locations suggests similar trends across the vertical and horizontal planes.”
