技術解説
Pointer Events and Mouse Events report button numbers, wheel deltas, timestamps, and coordinates. Polling-rate estimates use the interval between pointermove events, but browsers coalesce and throttle events, so the result is only a rough indication.
Buttons 3 and 4 are back and forward on many mice, but browser and operating-system mappings differ. High-DPI sensors cannot be calibrated accurately from JavaScript without a known movement distance.
トラブルシューティング
Side buttons do nothing
Browsers often reserve back and forward buttons for navigation. Some mice map them to keyboard shortcuts instead.
Double-click is not detected
Adjust the operating-system double-click speed or test again with a deliberate pair of clicks.
Pointer movement looks jumpy
Close background applications and check whether browser hardware acceleration is enabled.
Polling rate looks low
Browsers throttle pointer events. A low estimate does not prove a low polling rate.
