A Method of Evaluating User Visual Attention to Moving Objects in Head Mounted Virtual Reality

摘要

Virtual reality games/films/applications bring new challenges to conventional film grammar and design principles, due to more spatial freedom available to users in 6-DOF Head-Mounted Display (HMD). This paper introduces a simple model of viewers' visual attention in environment of virtual reality while watching randomly generated moving objects. The model is based on a dataset collected from 10 users in a 50-seconds-long virtual reality experience on HTC Vive. In this paper, we considered three factors as major parameters affecting audiences' attention: the distance between object and the viewer, the speed of objects movement, and the direction of object towards. We hope the research result is useful to immersive film directors and VR game designers in the future.
