Immersivity Core Library 🚀

Immersivity's core library enables you to create interactive web experiences using your camera. Transform ordinary websites into dynamic 3D environments by responding to head movements. 🎥🌐

Features ✨

• Real-time Face Detection: Utilize TensorFlow.js and MediaPipe to detect faces and track head movements. 🕵️‍♂️
• Parallax Effect: Apply 3D rotation effects to elements based on head movements. 🔄
• Event Emitter: Subscribe and unsubscribe to face movement events. 🔔

Installation 📦

To install the library, use npm or yarn:

npm install immersivity-core
# or
yarn add immersivity-core

Usage 📘

Setting Up the Video Element 📹

First, set up the video element that will be used for face detection:

import { setVideoElement } from 'immersivity-core';

async function setupVideo() {
  const videoElement = await setVideoElement();
  // Do something with the video element if needed
}
setupVideo();

Starting Face Parallax 🎛️

Once the video element is set, start the face parallax effect:

import { startFaceParallax } from 'immersivity-core';

async function startParallax() {
  const videoElement = await setVideoElement();
  startFaceParallax(videoElement);
}
startParallax();

Wrapping Elements for Parallax 🌀

Wrap the elements you want to apply the parallax effect to:

import { wrapParallax } from 'immersivity-core';

const element = document.getElementById('myElement');
wrapParallax(element);

Subscribing to Face Movement Events 🔔

You can subscribe to face movement events to perform custom actions:

import { subscribeToEventEmitter } from 'immersivity-core';

function handleFaceMovement({ centerX, centerY, rotationX, rotationY }) {
  console.log(`Center X: ${centerX}, Center Y: ${centerY}`);
  console.log(`Rotation X: ${rotationX}°, Rotation Y: ${rotationY}°`);
}

subscribeToEventEmitter(handleFaceMovement);

Unsubscribing from Face Movement Events 🚫

To unsubscribe from the events:

import { unsubscribeFromEventEmitter } from 'immersivity-core';

unsubscribeFromEventEmitter(handleFaceMovement);

Get Parallax Container Class Name 🏷️

Retrieve the class name used for the parallax container:

import { getParallaxContainerClassName } from 'immersivity-core';

const className = getParallaxContainerClassName();
console.log(`Use this class for parallax container: ${className}`);
