Why it is worth attention

It provides a pluggable input abstraction (IMotionSource) so the canvas never depends on a specific sensor, and implements pointer stability via a One Euro filter, careful rumble state preservation, and a non-blocking read loop.

Who it is for

MonoGame/XNA developers building motion-controlled displays
Game developers exploring alternative input with real hardware
Hobbyists wanting to repurpose a Wii Remote for interactive projects
Developers porting legacy Kinect/XNA movement-controlled displays

Use cases

Interactive art installations with gesture-driven canvas
Educational demos using motion and pointing as input
Game prototyping with physical controller feedback (rumble, LEDs)
Gesture-based UI for desktop applications

Strengths

Pluggable IMotionSource abstraction allows switching sensors without touching canvas code
Pointer stability maintained by One Euro filter, avoiding trade-off between still and responsive cursor
Rumble state is preserved across all output reports, preventing accidental motor off/on
HID reads run on dedicated thread with no allocation, keeping render loop responsive

Considerations

Windows-only: Bluetooth HID pairing and build steps require Windows
Status shows all features as unchecked, indicating the implementation may be incomplete or a design outline
Requires a physical Wii Remote and IR sensor bar; no emulation or alternative controller provided

README quick start

wiimote-motion-display

A C#/.NET interactive display driven by a real Wii Remote over Bluetooth: motion, pointing, and gestures mapped to an on-screen canvas in real time.

A gaming motion controller is a cheap, precise, and genuinely fun way to drive an interactive display, but the value is in the plumbing: reading the controller over Bluetooth HID, turning noisy accelerometer and infrared data into stable pointing, motion, and gestures, and mapping that onto something on screen without lag. wiimote-motion-display does that end to end. A Wii Remote connects over Bluetooth HID; its accelerometer, IR camera, and buttons drive a pointer, tilt and motion, and recognized gestures on an interactive canvas built with MonoGame.

Scope note: the input layer is pluggable, with the Wii Remote as the reference device. The canvas is built on MonoGame, the open-source continuation of the XNA Framework, so the programming model is the same one legacy Kinect/XNA projects use, and porting the render side to XNA on Visual Studio is direct. This is my own hardware, built and tested for real.

Bluetooth HID. Pairs the Wii Remote and reads its HID report stream: buttons, the 3-axis accelerometer, and the IR camera's tracked points. No vendor SDK, just the HID protocol.
Pointer. Computes an on-screen pointer from the IR camera and sensor bar (or any IR sources), with smoothing so it sits still when your hand does.
Motion and orientation. Derives tilt and motion from the accelerometer (and the MotionPlus gyro if the remote has one).
Gestures. Recognizes flicks, swings, shakes, and holds from accelerometer patterns.
Interactive display. A MonoGame canvas responds to the pointer, motion, and gestures in real time: move and throw objects, draw, and trigger actions, with rumble and LED feedback.

Why it maps to Kinect/XNA work

The hard parts of a movement-controlled display are the same whatever the sensor: read a noisy real-time input, turn it into stable motion and gestures, and drive a responsive display. This project does
