In marketing, user experience research, product design, sports analysis, and other fields, understanding “what people are looking at” is key to gaining insights into behavior and psychology. Eye tracking glasses use one camera to record eye movements and another to record the scene. AI determines the pupil center in real time and overlays a crosshair on the scene video, showing exactly where the wearer is looking. This technology allows us to objectively study consumers’ gaze trajectories, athletes’ visual attention, and users’ browsing patterns.
However, the value of eye tracking data heavily depends on the quality of the scene camera. If the scene video is blurry, distorted, or noisy in low light, the overlaid gaze points become meaningless. A high-performance scene camera module needs high resolution, auto focus, ultra-wide angle, low distortion, low-light optimization, and cross-platform plug-and-play to work seamlessly with eye tracking algorithms, delivering realistic, clear, and usable gaze analysis data.
Unlike conventional cameras, the scene camera for eye tracking glasses faces demanding requirements:
High Resolution: Must capture fine details – product labels on shelves, athlete footwork, text buttons on screens. 8MP is sufficient for professional analysis.
Auto Focus: Wearers naturally look at objects at varying distances (from phones at 30cm to billboards far away). Auto focus ensures sharpness at any distance.
Ultra-Wide Field of View: Human natural field of view is relatively wide; the camera should cover a similar range to avoid missing peripheral gaze points.
Low Distortion: Wide-angle distortion warps spatial relationships, affecting accurate gaze point mapping.
Low-Light Performance: Indoor stores, twilight outdoor scenes; large aperture and back-illuminated sensor keep images bright.
Plug-and-Play: USB connection to computers or mobile devices; UVC driver-free simplifies data collection.
Based on our understanding of embedded vision and wearable devices, a scene camera module truly suited for eye tracking glasses achieves precise alignment across resolution, focus, field of view, optics, and interface.
In user experience research, researchers need to know exactly which product, which line of text, or which button the user looked at. Insufficient resolution blurs these details, making precise gaze annotation impossible.
This 8MP Camera Module features the Sony IMX179 back-illuminated CMOS sensor (1/3.2-inch) , outputting 3288×2512 (8MP) ultra-high resolution and supporting smooth 1080P@30fps video. Key advantages:
8MP ultra-high pixel count: Approximately 8 million effective pixels. At 2-3 meters, it clearly distinguishes brand logos, small package text, and screen button labels. Researchers can zoom in post-analysis and still maintain clarity.
IMX179 back-illuminated sensor: The back-illuminated structure greatly improves light sensitivity, reducing noise and delivering cleaner images in low-light environments.
Dual output modes: Capture 8MP stills for static analysis, or record 1080P@30fps video for dynamic gaze trajectory mapping, balancing fluidity and detail.
For eye tracking glasses, 8MP means “see everything, clearly”—every gaze point maps to a specific scene element.
People wearing eye tracking glasses naturally shift their gaze between different distances—from a phone at 30cm to a street sign at 20 meters. A fixed-focus camera cannot cover both extremes, leading to blurry frames and invalid gaze data.
This module features built-in Auto Focus (Auto Focus Camera Module) that quickly adjusts focus. Advantages:
Fast locking: From close-up (about 10cm) to infinity, autofocus completes in milliseconds.
Paired with F2.0 large aperture, it focuses quickly even in low light.
No user intervention needed; as the wearer naturally moves, the camera automatically keeps the畫面 sharp.
For eye tracking analysis, auto focus means “whether looking near or far, the gaze point always falls on a sharp image.”
Human binocular horizontal FOV is about 120°, monocular about 90-100°. The scene camera’s FOV should be as close as possible to this range to fully capture what the wearer sees. Also, wide-angle distortion warps spatial relationships, causing gaze point calculation errors.
This Wide Angle Camera Module features a 78.4° diagonal wide-angle with distortion controlled to < -1.5% (near zero distortion). Advantages:
78.4° FOV (horizontal about 65°) is close to the effective monocular human FOV, reducing edge blind spots.
Ultra-low distortion keeps straight lines straight and object shapes true, ensuring gaze points map accurately.
Paired with AI pupil localization, the overlaid crosshair closely matches the actual gaze point.
For marketing and product research, low-distortion wide angle means “what they see is what we measure”—researchers know exactly which product or text the consumer looked at.
Eye tracking studies often take place in dim environments like stores, restaurants, or outdoor at dusk. Ordinary cameras produce dark, noisy footage, making scene content recognition unreliable.
This module‘s F2.0 large aperture combined with the IMX179 back-illuminated sensor dramatically increases light intake, delivering superior low-light performance. Advantages:
Under indoor lighting (100-300 lux), the image is bright with natural colors.
At twilight outdoors (10-50 lux), it still outputs usable images with acceptable noise.
Reduces dependence on additional fill lights, preserving natural behavior.
Eye tracking glasses typically connect to a laptop or tablet for data collection. Researchers don’t want to spend time installing drivers.
This module uses a USB interface with built-in UVC Camera Module driver-free protocol, supporting USB Camera Module plug-and-play. Advantages:
Connects to Windows, Linux, Android, macOS devices, automatically recognized without drivers.
Works with eye tracking software to display real-time scene video and gaze overlay.
Low-latency transmission ensures synchronization between gaze and image.
1. Retail Shelf Eye Tracking Analysis: Shoppers wear glasses while freely walking in a supermarket. The 8MP HD camera records shelf scenes; auto focus keeps everything sharp from close-up promo tags to high shelves. Researchers replay data to analyze dwell time and gaze order, optimizing product placement.
2. Web & App UX Testing: Users wear glasses while browsing websites or using mobile apps. The camera records the screen. 78.4° wide angle covers the entire screen; low distortion ensures accurate UI element positions. Auto focus adapts to varying screen distances. Analyze gaze heatmaps to improve interface design.
3. Sports Athlete Visual Training: Soccer players wear glasses during practice. The camera records the field. 8MP clearly captures teammate positions, opponent movement, and ball location. Coaches analyze whether the athlete‘s gaze is properly distributed, enhancing tactical awareness.
4. Driving Behavior Research: Drivers wear glasses in simulators or on real roads. The camera records the road ahead, dashboard, and mirrors. Wide angle covers the entire traffic scene; auto focus handles near and far. Analyze attention distribution to improve safety.
The core value of eye tracking glasses lies in “revealing people’s true visual attention.” Adding an 8MP ultra-high-definition, auto focus, 78.4° ultra-low distortion wide-angle, F2.0 large aperture, UVC driver-free USB camera module makes the scene video clear, true, and stable, giving eye tracking data real analytical value. Researchers no longer guess what users looked at—they see it objectively through high-quality video and precise gaze overlays.
