Latency Measurement in Head-Mounted Virtual Environments

In this paper, we discuss a generalizable method to measure end-to-end latency. This is the length of time that elapses between when a real-world movement occurs and when the pixels within a head-mounted display are updated to reflect this movement. The method described here utilizes components commonly available at electronics and hobby shops. We demonstrate this measurement method using an HTC Vive and discuss the influence of its low-persistence display on latency measurement.
