Reorienting viewpoint with respect to body pose for 360 degree videos in confined space
Seokjun Hong, Gerard Jounghyun Kim · 2017
In this paper, we present a functionality of resetting the viewpoint into the 360 degree video relative to the user's body pose. Such a functionality can improve the usability of the 360 degree videos in terms of reducing excessive movement, thereby reducing fatigue and more usable in the public setting. Two variant methods are proposed and compared to the baseline case (no resetting possible) in terms of usability and content understanding. In both methods, the user can select a particular direction and associated view, then turn the body to a nominal direction and apply the reset. In method 1, the video stops (screen going to black momentarily) in between these actions, while in 2, the video continues. The Method 1 was found to be the viable method for viewpoint recalibration for casual viewing in a constrained public setting that can minimize excessive physical movement, yet not much different from the baseline case (freely rotate in 360 degrees) in terms of sickness, disorientation and content understandability.
