Birkmire, Deborah P., Karsh, Robert, Barnette, B. Diane, Pillalamarri, Ramakrishna and DiBastiani, Samantha (1993): Eye Movements in Search and Target Acquisition. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 1305-1309.

“The frequency distribution of eye fixations and fixation durations during a search and target acquisition task was examined to determine if the allocation of visual attention was related to target, scene, and/or observer characteristics. Ninety computer-generated scenes simulating infrared imagery and containing different levels of clutter and zero, one, two, or three targets were produced. Targets were embedded in these scenes counterbalancing for range and position. Global and local clutter were measured using both statistical variance and probability of edge metrics. Thirty-three aviators, tankers, and infantry soldiers were shown still video images of the 90 scenes and were instructed to search for targets. Results of multiple regression analyses of global clutter, local clutter, range, number of targets, target dimensions, target complexity, and group membership on eye fixations and fixation durations are given and discussed in terms of search strategies.”

Birkmire, Deborah P., Karsh, Robert, Barnette, B. Diane and Pillalamarri, Ramakrishna (1992): Target Acquisition in Cluttered Environments. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1425-1429.

“The relationship of human target acquisition times and detection probabilities to electronically measured visual clutter was investigated. Ninety computer-generated scenes simulating infrared imagery and containing different levels of clutter and zero, one, two, or three targets were produced. Targets were embedded in these scenes counterbalancing for range and position. Global and local clutter were measured using both statistical variance and probability of edge metrics. Thirty-three aviators, tankers, and infantry soldiers were shown still-video images of the 90 scenes and were instructed to search for targets. Analyses indicate differences between the aviators and tankers in search times and types of errors. Results of multiple regression analyses of global clutter, local clutter, range, target dimension, target complexity, number of targets, and experience on search times are given and discussed in terms search strategies.”

Birkmire, Deborah P. (1991): Auditory Performance: A Model to Predict Performance as a Function of Auditory Workload: Linguistic Factors. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 618-621.

“Those linguistic and extra-linguistic factors which appear to be promising candidates for inclusion in a model of auditory workload are discussed. In particular, a method for measuring redundancy in a message set in suggested. Data is reported showing a highly significant correlation between measured redundancy and task performance. Future research directions are proposed.”
