heatmap.js features and specs

Ease of Use
heatmap.js is designed to be simple and easy to use, allowing developers to quickly create heatmaps with minimal setup and configuration.
Customization
The library offers a wide range of customization options, allowing users to adjust colors, opacity, radius, and gradient to fit the desired aesthetic and data representation needs.
Performance
heatmap.js is optimized for performance and can handle large datasets efficiently by utilizing WebGL rendering when available.
Cross-Browser Compatibility

Extensive Documentation
Comprehensive documentation is available, providing detailed guidance and examples for various use cases and configurations, which helps developers get up to speed quickly.

Possible disadvantages of heatmap.js

Limited to 2D Heatmaps
heatmap.js is focused solely on 2D heatmap creation, which may be limiting for developers looking to create 3D heatmaps or more complex data visualizations.
Dependency on JavaScript
As a JavaScript library, developers need to be familiar with JavaScript to use heatmap.js effectively, which could be a barrier for those proficient in other programming languages.
Potential Performance Issues with Very Large Datasets
While the library handles large datasets well, extremely large datasets or high-density points can still potentially impact performance and responsiveness.
Limited Features Compared to Full-Fledged Data Visualization Libraries
Compared to more comprehensive visualization libraries like D3.js or Chart.js, heatmap.js is specialized and may lack some advanced capabilities and integrations offered by these full-featured libraries.
May Require Additional Libraries for Advanced Features
Developers may need to integrate heatmap.js with additional libraries or tools to achieve more advanced visualization features or better integrate the heatmap into a larger application framework.

WebGazer.js features and specs

Open Source
WebGazer.js is an open-source library, allowing developers to freely use, modify, and distribute the code, fostering collaboration and innovation.
Ease of Integration
The library is designed to be easily integrated into web applications, requiring minimal setup and enabling quick implementation of eye-tracking features.
No Special Hardware Required
WebGazer.js uses a web camera to perform eye-tracking, eliminating the need for specialized hardware, which makes it accessible to a broad audience.
Real-time Tracking
The library provides real-time gaze tracking, making it suitable for interactive applications requiring immediate feedback.
Cross-Platform Compatibility
As a JavaScript library, WebGazer.js works across different browsers and platforms, increasing its usability in diverse environments.

Possible disadvantages of WebGazer.js

Accuracy Limitations
The accuracy of WebGazer.js may not match that of dedicated eye-tracking hardware, which can limit its use in precise applications.
Environmental Dependency
Lighting and camera quality can affect the performance of WebGazer.js, posing challenges in uncontrolled environments.
Browser Performance Variability
The performance and accuracy of the library might vary between different browsers due to discrepancies in camera access and processing capabilities.
Privacy Concerns
Using a webcam raises privacy issues, as it involves capturing video data from users, which may require clear consent and data handling policies.
Limited Functionality
While useful for basic eye-tracking, WebGazer.js might lack the advanced features provided by specialized eye-tracking software or libraries.

Building a realtime eye tracking experience with Supabase and WebGazer.js
I had ran into WebGazer.js a while back when I first had the idea for this project. It's a very interesting project and works suprisingly well! - Source: dev.to / 5 months ago
Any way to detect a hand for touchless navigation?
You could use something like https://webgazer.cs.brown.edu/ for reference, or tensorflow.js. Source: over 2 years ago
A Drawing I've been working on since I finished the game.
If you are looking for some extra ideas... Mmm... If I were to make something like this, I would display it in a webapp with a simple eye tracking system (like this one, for example) so that, when it doesn't detect anyone looking towards the screen, it automatically changes the background. It requires some work and coding experience, so I am not expecting anyone to actually realize it, but... Hey! If someone... Source: over 2 years ago
Controller for pain-free reviewing in MedSchool (Mac, iPad)
Ankimote developer here. I was thinking about writing something to control Anki using this gaze tracking library, but I came to realize it would be slower than finger movements since you'd need to keep your gaze in an area for a second or two to avoid false positives. It also takes a good deal of effort to consciously focus your eyes at a small area of a screen, which would probably distract the user from thinking... Source: over 3 years ago
Webcam and browser eyetracking libraries?
Do you know about JS libraries which can be used in the browser to perform eyetracking (gaze prediction) using a webcam? I was giving a look at the WebGazer JS but wanted to know if there are some other alternatives out there. Source: almost 4 years ago
