Wiimote Whiteboard for Mac

Overview: Turn Any Flat Surface into an Interactive Board

Wiimote Whiteboard is a macOS app that lets you convert ordinary walls, tables, or whiteboards into an interactive display. It uses the Wiimote’s built-in IR camera to track an infrared pen, so you don’t need any dedicated smartboard hardware to draw, point, or control your Mac from a distance.

What you’ll need

• A Mac running the application.
• A Nintendo Wiimote to act as the IR camera.
• An infrared pointer — buy one online or construct a DIY version using the instructions provided by the app’s website.
• (Optional) Additional Wiimotes to expand coverage or increase tracking accuracy.

Quick start checklist

• Position the Wiimote so its camera has an unobstructed view of the writing surface.
• Pair the Wiimote with your Mac over Bluetooth and launch the app.
• Follow the on-screen calibration routine to align the surface coordinates with your screen.
• Select whether the app should emulate mouse movement only or include click events.

Tips to improve tracking and accuracy

• If possible, use more than one Wiimote to reduce occlusion and improve precision.
• Eliminate competing infrared sources (strong sunlight, IR remote controls) that can confuse the camera.
• Keep consistent, moderate room lighting so the camera can distinguish the pen’s IR signal.
• Re-calibrate whenever you move the Wiimote, change the pen, or adjust the projection/screen mapping.

Customization and controls

The application provides options to tailor how the pen behaves:

• Choose between simple pointer movement and an input mode that registers mouse clicks or gestures.
• Adjust sensitivity and smoothing settings to match your drawing style and surface texture.
• Save profiles for different rooms, surfaces, or presenters to speed future setups.

Building or buying an IR pen

• Follow the step-by-step DIY directions available on the project site if you prefer a low-cost hand-made pen.
• If you want a ready-made option, infrared styluses and pens are available from several online retailers.

Advanced uses and multi-Wiimote setups

Using multiple Wiimotes is recommended for larger surfaces or to reduce blind spots. The app can combine input from two or more units for smoother tracking and fewer interruptions during demonstrations.

Alternatives and resources

• CheatSheet (free) — a lightweight utility to review shortcuts and useful tips while presenting.
• Other paid or open-source whiteboard solutions — consider these if you need deeper integration with conferencing or advanced stylus pressure sensitivity.
