Gopher, Daniel, Kimchi, Ruth, Seagull, F. Jacob, Catz, Irit and Trainin, Ori (1992): Flying with Dichoptic Displays: The Interplay between Display Characteristics and Attention Control. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1469-1473.

“Interest in the study of attention control under dichoptic conditions is instigated by the contemporary development of night-vision systems based on single-eye helmet-mounted displays. Two experiments were conducted to investigate the concurrent performance of a tracking task and letter classification under dichoptic display conditions. Subjects were required to fly a simulated helicopter path while classifying letter pairs presented intermittently. Experimental instructions in Experiment A specifically emphasized a two-dimensional interpretation of the visual field. Under these instructions, the presentation of a common visual axis to the two eyes provided by the flight-tunnel did not aid subjects, and their performance deteriorated in dichoptic conditions. In Experiment B, the instructions to subjects were changed to advocate a three-dimensional interpretation of the display. Under these instructions, dichoptic performance-levels were substantially improved when the tunnel was present. These results imply that the presence of a common visual axis is not automatically beneficial. In order to improve performance, attention should be intentionally directed to utilize information supporting a three-dimensional frame of mind. These findings have important implications for understanding the dynamics of performance with single-eye helmet-mounted displays, and the training of pilots in their use.”

Kimchi, Ruth, Rubin, Yifat, Gopher, Daniel and Raij, David (1989): Attention in Dichoptic and Binocular Vision. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1435-1439.

“The ability of human subjects to mobilize attention and cope with task requirements under dichoptic and binocular viewing was investigated in an experiment employing a target search task. Subjects were required to search for a target at either the global level, the local level, or at both levels of a compound stimulus. The tasks were performed in a focused attention condition in which subjects had to attend to the stimuli presented to one eye/field (under dichoptic and binocular viewings, respectively) and to ignore the stimulus presented to the irrelevant eye/field, and in a divided attention condition in which subjects had to attend to the stimuli presented to both eyes/fields. Subjects' performance was affected mainly by attention conditions which interacted with task requirements, rather than by viewing situations. An interesting effect of viewing was found for the local-directed search task in which the cost of dividing attention was higher under binocular than under dichoptic viewing.”

Raij, David, Gopher, Daniel and Kimchi, Ruth (1987): Perceptual and Motor Determinants of Efficient Data Entry. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 820-824.

“Two scales were constructed to separately evaluate the perceptual and motor difficulty of the finger chords employed to enter letters in a newly designed chord keyboard, developed to provide an efficient alternative to the existing QWERTY keyboard. The index of motor difficulty evaluated the biomechanical problems associated with the execution of the 31 possible chord combinations of five-fingers. The perceptual index scaled the difficulty of identifying the spatial pattern created by each of the 31 chords. A regression equation that was based on the two indexes accounted for about 60% of the variance of actual typing on the chord keyboard. Perceptual and motor determinants appear to be equally potent and mostly independent in their influence on efficient data entry performance.”
