Abstract
Advances in automation have led to an increased prevalence of human multitasking in intelligence, surveillance, and reconnaissance operations. Despite advancements in computer-vision research, almost all video data collected must be processed by human analysts. Traditionally, analysts are plagued with the presence and possible overabundance of interruptions that fundamentally leads to multitasking while processing video data. It is currently unknown what factors influence decision making in completing primary tasks or handling interruptions. In this study, we investigated the performance effects and the resulting design implications of varying the number of concurrent prospective memory tasks and encoding of one large group of tasking information versus smaller, separate bits. Results indicate that working memory capacity significantly affects prospective memory performance and increasing concurrent targets degraded prospective memory performance. Target encoding format results failed to converge on a clear affect. This study demonstrates and highlights portions of the complex underlining mechanisms involved in human information processing and makes a case for the study and utility of prospective memory paradigms for human-machine interface design.e
