                    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.
