Description

Wide-view HMDs allow users to use their peripheral vision in a wearable augmented reality (AR) system. However, there have been few studies on information display methods that make use of a wide FOV in AR environments. In this study, we discuss and implement types of information display methods that make good use of a few types of wide FOV HMDs, and then we evaluate the effectiveness of these methods through a user study with real and virtual wide FOV see-through HMDs. In one of these methods, an annotation is presented near the border of the HMD's view with a lead line connected to the annotated object (outside of the HMD's viewing plane). An immersive CAVE-like environment is used to simulate a virtual see-through HMD as well as a virtual walk-through environment, and a prototype of a hyperboloidal head mounted projective display (HHMPD) is used as a real see-through HMD. Experimental results show that the methods with lead lines improve target discovery rates compared to a method that overlays annotations directly over the target's position. Additionally, it was shown that annotations with an added blinking effect have little effect on target discovery rates regardless of viewing angle.
