Gaze Demo

What is Gaze Demo?

Okay, so here's the deal with Gaze Demo – it's one of those AI tools that just feels a bit sci-fi when you first try it. Essentially, it's a lightweight gaze detection application built around this clever model called Moondream. The whole point is to analyze where someone's looking in a given image or frame.

Think about all those times you've wondered what a person in a photo is focused on – are they looking at the camera, at another person, off into the distance? Gaze Demo gives you the answer. It's perfect for photographers checking if the subject's eyes are connected with the lens, researchers studying human attention, UX designers testing where people look on an interface, or honestly, just curious folk like you and me who want to play with some seriously smart tech.

Key Features

• Precise Gaze Estimation: It zeroes in on a person's pupils to figure out the exact direction of their gaze. This isn't a rough guess – it's a surprisingly accurate line of sight. • Minimalist and Fast: Since it runs on the Moondream model, it's designed to be quick and responsive. You won't be waiting around forever for a result. • Image-Based Analysis: Just drop in your favorite photo or screenshot, and it'll do the rest. No video stream or live camera needed if you don't want it. • Clear Visual Output: You'll typically get an image back with a visual indicator – often a line or vector drawn right on the face – showing you precisely where the eyes are pointing. • No Need for 300 Faces: You don't need a massive database of human faces. It's great for analyzing single people in everyday photos.

How to use Gaze Demo?

Using it is a piece of cake, really. Just follow these steps:

1. Pick Your Photo: Start with a clear image that has at least one person's face in it. Headshots work best, but even portraits can do the trick as long as the eyes are visible.
2. Load It Up: Upload your chosen image into the Gaze Demo interface. It'll automatically start processing.
3. Let the Magic Happen: Moondream gets to work, identifying the face and specifically the eyes within the image.
4. Read the Results: After a moment, you'll see your picture again, but this time it will have the gaze direction overlaid – usually a simple line showing you exactly where they seem to be looking.
5. Interpret the Data: Now you can see it! Is your subject making eye contact with the viewer? Are their eyes drawn to that bird in the corner of the picture? Suddenly, a simple photo tells a deeper story.

The really cool thing? You can do this over and over with different portraits to get quick, fascinating insights.

Frequently Asked Questions

How accurate is the gaze detection? It's impressively accurate, especially with clear, front-facing portraits. Like any AI, it can be tripped up by very poor lighting, heavy shadows across the eyes, or extreme angles, but for most standard photos, it nails it.

Does it work with multiple people in one photo? Right now, it's primarily designed to analyze one person at a time. If you feed it a group photo, it will typically pick the most prominent face to focus its analysis on.

What exactly does it need from a photo to work? The most important thing is a clear, visible view of the person's eyes and the general front of their face. Sunglasses, hands covering the eyes, or faces turned too far to the side will prevent it from working properly.

Can it analyze live video from my webcam? That's a really fun idea, and while the technology behind it absolutely could be used for video, the Gaze Demo app as described is focused on static images. The steps would be almost identical for a video feed, just happening frame-by-frame.

Do I need a super powerful computer to run this? Not at all! One of the neat things about the Moondream model is that it's optimized to be fairly lightweight, so you don't need a top-of-the-line gaming rig to get quick results.

Can I quantify exactly how far to the left or right they're looking? This version focuses on the qualitative direction more than precise quantitative metrics. You interpret where the gaze is pointing by looking at the visual overlay on the image.

Is it only good for human faces? Great question. While the model is trained predominantly on human facial data, it might attempt to estimate a "gaze" for animals or even illustrations, but the accuracy for anything other than a human face would be a total crapshoot and not something you can rely on.

My photo won't process. What's probably wrong? Ninety-nine times out of a hundred, it's because the face or eyes aren't clear enough for the AI to get a lock. Try a different photo where the person is looking more or less toward the camera and their eyes aren't obscured.
