Mouse Pointer Accuracy

A web app for measuring mouse pointer accuracy and speed.

It asks you to click 8 circles on the browser screen in a fixed order as quickly and accurately as possible, then computes a score from the elapsed time and the number of miss-clicks. Useful for comparing pointing devices such as mice, trackpads, and trackballs.

Features

• Test pattern: sequential-1 (click 8 points in the order 1→2→3→4→5→6→7→8→1 for 3 laps)
• Metrics: total time, hit / miss count, miss rate, average inter-click interval, score
• Score formula (sequential-1): 120 - elapsed seconds - misses × 2
• Guidance: arrows show your next move (solid red = current move, dashed amber = next preview)
• Feedback: pulse animation on hit; red X mark and screen edge flash on miss
• Persistence: results saved with a name in browser localStorage
• Export: download individual or bulk records as JSON / TSV / Markdown
• i18n: auto-switch between Japanese / English based on browser language
• Fully client-side (no server, data stays in the browser)
