Latency

The Mysterious World of Latency!!!

There is NO consensus as to what constitutes real-time. Both an (FPS) gamer and musician will tell you that lower is better. At this time, we are not looking to start a 'Bruce Lee' style argument, but merely mention observations that have been reported to us.

• In 1968 Robert Miller stated "100ms is perceived as instantaneous".
• Gamers & Musicians will tell you <10ms is reasonably good!

We strive to reduces latency to the point where it becomes imperceptible.

• In VR studies, it has been found we can visually detect 1ms.
• Touch is also approximately 1ms.
• Reaction time typically ranges from 1/4 sec to 2 secs (mostly on age.)
• Test Your Reaction Time!

Human perception varies with the individual, the specific senses (sight, sound, touch...) and the environment (mobile, cinema, VR, AR, mixed reality).

We use a psuedo-state-machine approach to keep latency the lowest possible within the limits of the computers architecture (hardware and OS).

Minimizing (Perceptual) Latency:

• Hardware with SYNC brings video latency to minimum possible.
• VR can anticipate head movement (based on physics.)
• Software can run within the limits of the OS (1-20ms typical.)
