Evaluation on Relationship between Useful Field-of-View and Presentation Method in Optical AR Head-Mounted-Display

What is it about?

The use of wearable devices may narrow the user’s UFOV (Useful Field Of View). Not only presenting information by wearable devices but also wearing wearable devices themselves may increase cognitive load, and it causes the UFOV narrowing. It is important to understand how wearable devices affect the UFOV because the narrowed UFOV could lead to overlooking surrounding objects. This paper confirmed that wearing the optical AR HMD significantly narrows the UFOV, and presenting information further narrows it significantly.

Why is it important?

Since the size of the effective field of view is greatly related to the degree of danger awareness and accident avoidance, if the effective field of view is reduced by wearable devices, it is necessary to design and devise ways to prevent the effective field of view from being reduced. This study is valuable in that it shows that simply wearing an HMD without any information presentation can reduce the effective field of vision.
