In the field of augmented reality technologies, commercial optical see‐through‐type wearable displays have difficulty providing immersive visual experiences, because users perceive different depths between virtual views on display surfaces and see‐through views to the real world. Many cases of augmented reality applications have adopted eyeglasses‐type displays (EGDs) for visualizing simple 2D information, or video see‐through‐type displays for minimizing virtual‐ and real‐scene mismatch errors. In this paper, we introduce an innovative optical see‐through‐type wearable display hardware, called an EGD. In contrast to common head‐mounted displays, which are intended for a wide field of view, our EGD provides more comfortable visual feedback at close range. Users of an EGD device can accurately manipulate close‐range virtual objects and expand their view to distant real environments. To verify the feasibility of the EGD technology, subject‐based experiments and analysis are performed. The analysis results and EGD‐related application examples show that EGD is useful for visually expanding immersive 3D augmented environments consisting of multiple displays.
