6DOF GearVR Controller Tracking

An easy way to use GearVR for more complicated use cases such as VR game that need 6DOF tracking.

How it works

• Camera tracks colors for position tracking.
• Gear VR controllers already have Built-in 3DOF tracking.

What you need

• 1 or 2 Gear VR controllers
• Black electrical tape
• Illuminated Shuttlecocks
• Scissors
• 110 Deg Webcam

Software

Client Side

import { ClientTracking } from "./dist/GearVRController.js";

var tracking = new ClientTracking(codePreviewElement, threejsHandObject);

Server Side

import { ServerTracking } from "./dist/GearVRController.js";

var tracking = new ServerTracking(clientCode);

NodeJS Socket Server

const { Server } = require("socket.io");
const { createServer } = require('http');

const server = createServer(app);
const io = new Server(server);

io.on('connection', (socket) => {
    console.log('User connected ' + socket.id);

    socket.on("controllerDataOut", (id, data) => {
        socket.to(id).emit("controllerDataIn", data);
    });
    
    socket.on('disconnect', () => {
        console.log('User disconnected');
    });
});

server.listen(8080, () => {
    console.log(`Web app listening on port ${8080}`);
});

Steps to reproduce

Prepare lights

• Get 2 shuttlecocks and make sure that one is red and one is green.
• Cut the feathers off of the shuttlecocks.
• Remove the blue tape off both of the shuttlecocks.

Tape the lights

• Cut off the tape into 3 bits width ways so you have 3 smaller bits of tape.
• Tape one on one side and the other on the oppersite side of the light.
• Finish by Wrapping the 3rd bit around the whole bottom like the blue tape was.
• Attach both loose ends of tape to both sides of the controller.
• Fill in the gaps with more tape making sure that none of it sticks to the controller so it is easy to turn on and off the light.
• Repeat for the second controller.
• You should now have 2 controllers that look simular to mine.

Final steps

• Plug in your webcam.
• Open the webpage in a chromium-based browser.
• Your done!
