In the latest SteamVR Beta update, Valve acknowledges that they underestimated the physical capabilities of a human being trying to beat a leader board score. Apparently it has led to their need to “Increase limits of what we thought was humanly possible for controller motion based on tracking data from Beat Saber experts”.
Valve developers had to fix an issue in their Lighthouse motion tracking technology because expert Beat Saber players were moving too fast to be tracked, resulting in misses that should have been hits, and, I have to assume, rage all round. Beat Saber is a VR rhythm game in which you wield two sabers, made of light, to hack and slash poor defenseless blocks, in time to the music. Valve’s developers assumed that only regular human beings would be playing the game and did not account for the mutants amongst us. One such developer left this comment on the update:
The tracking system has internal sanity checks to identify when things go wrong. For example, if our math says you are *behind* your only basestation, clearly we made a mistake, because we wouldn’t be getting any signal from behind the basestation. One of these checks relates to how fast we thought it was physically possible for someone to turn their wrist. It turns out that a properly motivated human using a light enough controller could go faster (3600 degrees/sec!) than we thought.
Thanks to Kotaku, for allowing me to avoid doing maths, I now know that this is the equivalent of flicking your wrist from horizontal to vertical in .025 seconds. I bet you just tried it for yourself.
