EnglishWhat equipment do I need to use GazeRecorder's webcam eye tracking?
Updated
You only need a computer or mobile device with an ordinary webcam—no dedicated eye-tracking hardware is required. GazeRecorder's GazeFlow engine is described as a hardware-independent technology that performs real-time eye movement tracking without physical contact, using a common webcam plus software running on a PC. The same webcam-based approach is listed for desktop and mobile devices, and there is published research on web-based eye-tracking performance under different lighting conditions, so you don't need a controlled lab setup to get started.
Minimum setup
- A device with a webcam. A standard built-in or USB webcam on a PC, or a smartphone/tablet camera for mobile eye tracking.
- A browser and internet connection. The tools are online: GazeRecorder runs as a webcam eye-tracking app, and GazeCloudAPI.js lets you integrate real-time eye tracking into a website with a few lines of code.
- No physical contact equipment. GazeFlow tracks eye movement remotely, without any contact sensors or head-mounted gear.
What you can run with that setup
| Tool | What it does | Equipment note |
|---|---|---|
| GazeRecorder | Tracks eye movement and creates video recordings using your webcam | Webcam as input source |
| GazeCloud / Online Eye-Tracer | Cloud eye-tracking insights platform for remote behavioral research | Webcam-based, online |
| GazeCloudAPI.js | Adds real-time eye tracking to a website via code | Runs in the browser |
| GazePointer | Moves the mouse cursor with your eyes | Webcam eye tracker software |
| GazeBoard | Text entry using only an ordinary webcam | Webcam-based keyboard |
| GazeFlow | Real-time eye movement tracking engine | Hardware-independent, PC software + webcam |
Research and testing scenarios the same equipment supports
The site lists these use cases, all built on webcam tracking rather than lab hardware:
- Website eye-tracking heatmaps and behavior analytics
- Remote video testing to understand viewer engagement with ads and promotional videos
- Shelf testing to optimize product design against competitors
- Consumer behavior research in a virtual store environment
- Smartphone eye tracking alongside desktop
Practical conditions to keep in mind
- Lighting matters. One of the listed publications specifically investigates web-based eye-tracking system performance under different lighting conditions for neuromarketing—so treat your lighting as a variable you may need to adjust, not a fixed given.
- Accuracy is webcam-grade. The site lists "WebCam Eye-Tracking Accuracy" and "3D Gaze Tracking" as features, but this is consumer-webcam estimation, not a research-grade infrared tracker. Match expectations to the task.
- Remote, not in-person. The platform is positioned for online webcam eye-tracking because in-person research is challenging—useful if participants can't come to a lab.
If your goal is simply to try it, a laptop with a working webcam and a browser is enough to start. If your goal is precise gaze measurement for published research, plan to test under your actual lighting conditions first and confirm the accuracy meets your threshold.
