普段何気なく使っているスマホとかの方向による画面の向き切り替え、m5stackでの単軸ジャイロセンサだけでは誤差拾わないようにするのは至難の技だわ。こりゃいろいろ複合させて位置、向きの検出して、たまに補正かけて修正しているのか。分解能下げソフトフィルタかけてこの程度が限界だった。

"It is a very difficult technique to switch the screen direction depending on the direction of the smartphone that you usually use casually, and to avoid picking up errors with only a single axis gyro sensor with m5stack. This means that the position and orientation are detected by combining various things, and sometimes they are corrected and corrected. This degree was the limit with the resolution reduction soft filter."
