Low latency rendering in augmented reality based on head movement

Abstract

In Augmented Reality, AR, the latency is a huge problem that disrupts immersive experience especially when head-worn devices are involved. Rendering of virtual objects generally accounts for major proportion of the latency in AR. In this paper, we identify the problem caused by the latency and observe human perception of virtual objects during head movement to find opportunities to reduce the latency. We propose solutions that reduce the latency of rendering by introducing Level of Detail (LoD) concept based on head movement. Experimental results show our approach is effective to decrease the latency of rendering.
