Analysing the Effects of a Wide Field of View Augmented Reality Display on Search Performance in Divided Attention Tasks

  • A wide field of view augmented reality display is a special type of head-worn device that enables users to view augmentations in the peripheral visual field. However, the actual effects of a wide field of view display on the perception of augmentations have not been widely studied. To improve our understanding of this type of display when conducting divided attention search tasks, we conducted an in depth experiment testing two view management methods, in-view and in-situ labelling. With in-view labelling, search target annotations appear on the display border with a corresponding leader line, whereas in-situ annotations appear without a leader line, as if they are affixed to the referenced objects in the environment. Results show that target discovery rates consistently drop with in-view labelling and increase with in-situ labelling as display angle approaches 100 degrees of field of view. Past this point, the performances of the two view management methods begin to converge, suggesting equivalent discovery rates at approximately 130 degrees of field of view. Results also indicate that users exhibited lower discovery rates for targets appearing in peripheral vision, and that there is little impact of field of view on response time and mental workload.
