Task Demand of Sequentially Presented Information While Moving in Augmented Reality

Recently, a large number of devices using AR (augmented reality) have been developed. AR devices are useful tools for acquiring information from the external world as long as allocation of attention to the space operates without difficulty. For example, a temporal limitation of attention deteriorates response performance when information is sequentially presented. In this study, we investigated temporal characteristics of attention in a moving context using AR information in near and far spaces. Single and dual task conditions were compared. In the dual task condition, the observer was required to respond to detect and discriminate. Results indicated that information from AR devices with high task demand would reduce response performance if the observer focused attention to the space regardless of near and far conditions. Sequential presentation of AR images produces high cognitive loads, and therefore, more attention resources are required under these conditions.
