# Mouse Pointer Accuracy

# 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)
