I am building a proof-of-concept that lets a Raspberry Pi follow a user’s gaze and immediately translate that data into visual output on an attached screen. At the end of the job I want to be able to look at a point on the display and watch the system draw a corresponding dot, line, or free-hand stroke in real time. What I already have • Raspberry Pi 4 with camera interface available • Freedom to choose the most suitable eye-tracking library (OpenCV, MediaPipe, PyGaze, or similar) • One HDMI monitor for testing, though the code should remain display-agnostic so I can later swap in a touchscreen or e-Ink panel without major refactoring. What I need from you • Set up and calibrate the camera-based eye tracker on the Pi • Translate raw gaze coordinates into drawable vectors or cursor positions • Render those vectors on the active framebuffer or via a lightweight GUI (Pygame, Kivy, or other Python toolkit) • Commented Python code plus a quick-start readme so I can replicate the build on a fresh SD card. Acceptance criteria 1. Calibration completes in under one minute. 2. Gaze-to-pixel latency below 80 ms is demonstrated with a simple FPS counter. 3. A short demo records me drawing a continuous spiral with nothing but eye movement. If you have worked with low-latency vision pipelines on Pi or have an eye-tracking project to show, that will help me choose quickly.

Hi there, I understand you need a Raspberry Pi eye-tracking drawing system that captures gaze data and translates it into real-time visual output. This is an exciting computer vision project that combines hardware integration with sophisticated software processing. My approach involves using OpenCV for pupil detection and gaze estimation algorithms, combined with camera calibration techniques to map eye movements to screen coordinates. I'll implement this in Python for optimal performance on Raspberry Pi hardware, utilizing efficient image processing pipelines to ensure low latency between gaze tracking and visual feedback. The system will integrate camera modules, potentially custom IR lighting for better pupil detection, and create smooth drawing functionality that responds instantly to eye movements. I have experience with embedded computer vision projects on Raspberry Pi platforms, including real-time processing optimization and hardware-software integration challenges. This proof-of-concept will establish the foundation for accurate gaze-to-drawing translation with minimal lag, perfect for accessibility applications or innovative human-computer interaction research.

I can help you build this as a real-time gaze-to-drawing loop on the Pi 4. I’d structure it as a low-latency vision pipeline: capture at reduced resolution, detect face/gaze using MediaPipe FaceMesh or OpenCV’s pupil detection, then map gaze coordinates to screen coordinates via a quick 4-point calibration using homography. The calibration would be interactive and fit under one minute by collecting points automatically. To keep latency under 80 ms, the gaze detection and drawing run in separate threads sharing updated coordinates—no heavy GUI blocking. Rendering via Pygame stays display-agnostic, so you can swap HDMI for a touchscreen later without rewriting the core logic. If Python becomes the bottleneck, I’d move the calibration and vector math into C/C++ for speed. Deliverable is a clean, commented Python codebase with a README for replicating on a fresh SD card, plus the eye-only spiral demo with an on-screen FPS counter.

Turning gaze coordinates into live drawing strokes is the fun part, calibration is where it usually breaks. I'd use OpenCV for pupil tracking off the Pi camera, map the coordinates to a canvas, and smooth the jitter so lines come out clean instead of shaky. I can start today. Pricing and timeline shown are starting points, we'll firm them up once we walk through the full scope together. Happy to build a quick free demo of the gaze to cursor mapping first so you can see it tracking before you commit.

Hi, I can build this as a lightweight Raspberry Pi vision pipeline rather than overcomplicating it with a heavy framework. I have experience with OpenCV, MediaPipe, real-time camera pipelines, Raspberry Pi/edge deployment, and low-latency computer vision. I’ll handle camera capture, facial/eye landmark detection, gaze calibration, gaze-to-screen mapping, smoothing, and real-time rendering as separate modules so the display layer can later be replaced without changing the tracking pipeline. For the PoC, I’ll target: Sub-1-minute calibration workflow Real-time gaze coordinates mapped to display pixels Smooth dot/line/freehand drawing controlled only by gaze <80 ms end-to-end latency with FPS/latency measurements Raspberry Pi 4 optimized processing Clean Python code with configuration separated from core logic Quick-start documentation for rebuilding on a fresh SD card Demo showing a continuous eye-controlled spiral I’ll first benchmark the available camera pipeline and then choose the tracking approach that gives the best accuracy/latency on the Pi rather than forcing a specific library. If you provide the camera model, I can account for its capture pipeline and expected FPS from the start. Best regards, Zahid Hassan

A Pi that draws whatever you look at — that's a sharp proof-of-concept, and I can have it working fast. I am ready for this project immediately. I have similar components in stocks. Here's what I bring to this: → I've built low-latency vision pipelines on Pi before, so hitting your sub-80 ms gaze-to-pixel target is a matter of tuning, not guesswork. → I'll handle the full stack — camera calibration, gaze tracking with OpenCV/MediaPipe, and a display-agnostic renderer that won't break when you swap screens. → You'll get clean, commented Python, a quick-start readme for a fresh SD card, and a working spiral-drawing demo, all for $60. I can start right away and get this shipped. Let's talk details.

The 80ms gaze-to-pixel latency target is the part that will actually decide the architecture, since a Pi 4 running iris detection and rendering in the same process will blow past that if the pipeline isn't kept deliberately lean. I'd use MediaPipe's Face Mesh iris landmarks rather than a heavier OpenCV detection stack, since it's fast enough on-device to leave latency budget for rendering. Calibration would be a 5-9 point routine mapping iris offset to screen coordinates via homography, with drawing done through Pygame writing straight to the framebuffer so the touchscreen or e-Ink swap you mentioned doesn't touch the tracking code later, plus an FPS counter logged against the 80ms target as proof. One thing the brief doesn't specify: how should "pen down" and "pen up" be triggered for the spiral demo, since gaze position alone doesn't give you a natural way to start and stop a stroke, options are a blink, a dwell timer, or a separate key press. Happy to start once that's settled; I do freelance dev work rated 4.9/5 across past reviews on my profile if you want a quick look before deciding.

Salve, L'obiettivo è realizzare un sistema di eye-tracking basato su Raspberry Pi in grado di tradurre lo sguardo in un disegno in tempo reale su un display, garantendo una calibrazione rapida e una bassa latenza. Mantenere una latenza inferiore a 80 ms e ottenere una resa fluida nel disegno di una spirale assicurerà un'esperienza utente reattiva e il successo del proof of concept. - Esperienza nella creazione di pipeline di computer vision a bassa latenza su Raspberry Pi utilizzando OpenCV e Python - Familiarità con librerie di eye-tracking come MediaPipe e PyGaze e con la loro integrazione in toolkit GUI come Pygame - Realizzazione di progetti Python modulari e ben documentati, comprensivi di procedure di calibrazione e metriche di performance Sarà fondamentale garantire che la mappatura sguardo-pixel rimanga precisa su diversi display senza richiedere pesanti interventi di refactoring. Ha una libreria di eye-tracking preferita o devo valutare io quale sia la più adatta in termini di latenza e precisione? Inoltre, fornirà dati di esempio o script di test per la validazione?
