Evaluating user experience of 180 and 360 degree images

Abstract

This paper describes a comparison of user experience of virtual reality (VR) image format. The authors prepared the following four conditions and evaluated the user experience during viewing VR images with a headset by measuring subjective and objective indices; Condition 1: monoscopic 180-degree image, Condition 2: stereoscopic 180-degree image, Condition 3: monoscopic 360-degree image, Condition 4: stereoscopic 360-degree image. From the results of the subjective indices (reality, presence, and depth sensation), condition 4 was evaluated highest, and conditions 2 and 3 were evaluated to the same extent. In addition, from the results of the objective indices (eye and head tracking), a tendency to suppress head movement was found in 180-degree images.
