Why VisualGestures.js?

VisualGestures.js is an open-source TypeScript package that empowers users to effortlessly control the cursor, including actions such as hover, click, drag, and drop, through precise finger movements in the air.

1. Exceptional User Experience: Seamless, immersive interaction with intuitive gestures
Offers a seamless, touch-free interface with intuitive hand gestures, delivering an immersive and engaging experience ideal for gaming, virtual reality, and creative industries.
2. Novel Algorithm: Redefines gesture control with fluid and natural interactions, setting new standards
At its core, the innovative FKR algorithm precisely recognizes subtle hand movements, delivering fluid, accurate gesture control for natural, responsive interactions that elevate digital engagement.
3. Scalable and extensible: Designed to expand across multiple applications
Scalable and adaptable, suitable for various industries — from factory machinery control to automotive displays — offering flexible solutions for public kiosks and high-tech environments, enhancing enterprise interaction models.
4. Portable and Offline: Developed in TypeScript, works anywhere with full offline functionality
Developed in TypeScript, the solution is portable and reliable, offering full offline functionality, making it ideal for remote or restricted environments with consistent performance, regardless of location.
5. Smart Debugging: Advanced debugging capabilities for real-time insights and optimization.
Includes advanced debugging tools that deliver real-time performance insights, enabling quick optimization and efficient troubleshooting for seamless implementation by developers and end-users.

Getting started

1. Install our npm package

npm install @learn-hunger/visual-gestures

2. Integrate into your existing website

import { VisualGestures } from "@learn-hunger/visual-gestures/dist/";

/**
 *create instance of visual-gestures
 *which accepts optional parameters of container and the landmark to be used as pointer
 *[Default body and landmark 8 is used respectively]
 */
const vg = new VisualGestures();

// get hand landmarks from mediapipe's taskvision
// here video corresponds to 'HTMLVideoElement' with live webcam stream
const landmarks = handDetector.detectForVideo(video, performance.now());
vg.detect(landmarks.landmarks[0], performance.now());
// Virtual cursor can be seen once model loading and detection started successfully

For more information about ‘handDetector’, refer to the mediapipe handLandmarker documentation.

3. Currently offered cursor control events

// comprehensive list of all potential event types can be found within the 'EVgMouseEvents'
import { EVgMouseEvents } from "@learn-hunger/visual-gestures/dist/app/utilities/vg-constants";

// currently offered cursor control events
vgPointerMove();  // corresponds to 'onmousemove'
vgPointerEnter(); // corresponds to 'onmouseenter'
vgPointerLeave(); // corresponds to 'onmouseleave'
vgPointerDown(); // corresponds to 'onmousedown'
vgPointerUp(); // corresponds to 'onmouseup'
vgPointerClick(); // corresponds to 'onclick'
vgPointerDrag(); // corresponds to 'onmousedrag' ('onclick'+'onmousemove')
vgPointerDrop(); // corresponds to 'onmousedrop' ('onclick'+'onmousemove'+'onmouseup')

For each event, a callback on the ‘vgInstance[3.1]’ or via traditional event listeners [3.2], similar to cursor-based controls,, can be used

3.1. Instance Based Listening
Function corresponds to ‘onmousemove’ event in traditional cursor-based controls.

vg.mouseEvents.onPointerMove = () => {
  // console.log("callback pointer moved");
};

3.2. Traditional Event Based Listening

Function corresponds to ‘onmousemove’ event in traditional cursor-based controls.

import { EVgMouseEvents } from "@learn-hunger/visual-gestures/dist/app/utilities/vg-constants";
document.addEventListener(EVgMouseEvents.MOUSE_MOVE, () => {
  // console.log("callback pointer moved");
});

Similarly, ‘MOUSE_ENTER’, ‘MOUSE_LEAVE’, ‘MOUSE_DOWN’, ‘MOUSE_UP’, ‘MOUSE_CLICK’, ‘MOUSE_DRAG’, ‘MOUSE_DROP’ events can be listened to via instance based or traditional based listening.
