Inspiration

Mouse issues are deceptively hard to diagnose. When a mouse starts double-clicking, missing clicks, or the scroll wheel begins “jumping,” you often end up guessing—changing settings, swapping USB ports, reinstalling drivers—without a quick way to confirm what’s actually happening. I wanted a simple, browser-based tool that makes mouse input visible and easy to verify in seconds.

What it does

Mouse Tester is an online mouse diagnostic tool that provides:

  • A visual button map for Left / Right / Middle / Side buttons
  • Double-click issue detection to spot unintended rapid repeats
  • Scroll wheel direction & jump checks to catch erratic scrolling behavior
  • A lightweight event log so you can see what the browser is receiving in real time

How I built it

Mouse Tester is built as a fast, static web app:

  • Next.js (static export) + React + TypeScript
  • Tailwind CSS + shadcn/ui for a clean, accessible UI
  • Core detection uses standard browser mouse and wheel events, turning raw events into simple visual feedback and practical diagnostics.

Challenges I ran into

  • Browser/OS differences: Mouse buttons and wheel behavior can be exposed differently across browsers and operating systems, especially for side buttons and wheel deltas.
  • Avoiding false positives: Double-click and scroll “jump” detection needs to be helpful without overreacting to normal input variance.
  • UX balance: The tool had to feel immediate and simple—useful for non-technical users—while still surfacing enough detail to be meaningful.

Accomplishments that I'm proud of

  • A UI that lets you confirm button and scroll behavior instantly with minimal instructions.
  • Practical diagnostics focused on the most common real-world issues (double-clicking and scroll wheel jumping).
  • A lightweight, no-backend deployment that stays fast and easy to maintain.

What I learned

  • Input diagnostics is as much about communication as measurement—users need clear, actionable signals, not raw event noise.
  • Small UX decisions (labels, timing displays, visual highlighting) dramatically improve usability and trust.
  • Building for reliability means planning for edge cases across different mice, OS settings, and browsers.

What's next for Mouse Tester

  • Add more guided checks (e.g., drag/hold stability) while keeping the experience simple.
  • Expand dedicated test pages (click test, double-click test, scroll wheel test) and troubleshooting guides for common issues.
  • Improve clarity of results with better explanations and optional advanced detail for power users.
