An automotive head-up display system, or HUD, aims to improve passenger safety by projecting information such as navigation, warnings, and points of interest, to the driver’s visual field, ideally in real-time. The intention is to keep the driver’s focus on the road by reducing the eyes-off-the-road time and increasing situational awareness. Conventional HUDs produce a 2D image with a fixed, or static, projection. However, Augmented Reality (AR) HUDs produce a 3D image that adds depth and curvature to conventional HUD imagery and features a variable, or dynamic, projection.

End consumer experience with new technologies and products is paramount for their successful adoption. Head-mounted displays (HMDs) such as Sony, Pico, DPVR, HTC Facebook's Oculus, and others promise an immersive experience in augmented and virtual reality. For delivery of the promised experience, many factors are critical including motion-to-photon (MTP) latency. Poor performance of motion-to-photon latency leads to spatial disorientation, motion sickness and dizziness. In this post, we explore the importance of motion-to-photon latency, how to measure it and optimize HMD performance.
