Ask HN: How does a game like Just Dance score movement?
Hi HN, playing Just Dance on Switch while I am stuck inside. Can anyone explain how a game like Just Dance determines the accuracy of your dancing given a single Joy Con per dancer? Of course it uses telemetry such as the accelerometer, but what algorithms are at work? How does the game process the telemetry? Sometimes the scoring seems a bit arbitrary / not sensitive enough / too sensitive. What movements actually matter? For calibrating the songs, do they capture many dancers/repetitions and average it, or do they take the data from one good performance?
