See Reading Differently
Lexora uses eye-tracking technology to provide non-invasive dyslexia screening. Research-backed gaze analysis helps identify reading difficulties early — so every child gets the support they need.

Gaze Pattern Visualization
Built for Accuracy & Accessibility
Professional-grade eye tracking meets accessible webcam-based analysis — designed to make dyslexia screening available to everyone.
Dual Tracking Modes
Use the precision of Tobii eye trackers for clinical accuracy, or the convenience of any webcam with MediaPipe iris detection for broader access.
Engaging Calibration
Three calibration modes — classic grid, action stickman, and gentle star — with shrinking targets that adapt to different age groups.
Gaze Analytics
Fixation duration, saccade patterns, regression detection, and return sweeps — all the features that research links to reading difficulties.
Privacy First
All video processing happens in your browser. No video recordings are stored, and saved attempts persist only the gaze coordinates and metadata needed for research workflows.
Research-Backed
Reading tasks designed around established research — syllable decoding, pseudo-word recognition, and meaningful text comprehension for thorough analysis.
Age-Adaptive
From gamified star calibration for young children to precise grid-based calibration for adults. Lexora adapts the experience to each user.
How It Works
Three simple steps from setup to results. The whole process takes about 5 minutes and requires no prior technical knowledge.
Connect & Calibrate
Connect your Tobii device or grant webcam access. Our calibration process maps your unique gaze to the screen with precision.
Read the Passages
Three reading tasks — syllables, pseudo-words, and meaningful text — optimized for capturing the gaze features that matter.
Get Results
Our ML model analyses gaze patterns and provides a risk assessment with detailed fixation visualization and actionable recommendations.
Download Tobii Service
To use Lexora with a Tobii eye tracker, download the desktop service for your operating system. The service runs locally and streams gaze data to the web app.

About Lexora
Lexora is developed as a research initiative at the Faculty of Computing and Data Science. By combining eye-tracking technology with machine learning, we aim to make dyslexia screening accessible, affordable, and non-invasive — reaching children who might otherwise go undiagnosed.
Our approach builds on decades of research linking specific eye movement patterns — such as increased fixation duration, higher regression rates, and irregular return sweeps — to reading difficulties. Lexora captures these patterns through calibrated gaze tracking and analyses them using a trained neural network.
Important: This tool is for research and screening purposes only — it does not provide a clinical diagnosis. Results should always be interpreted by qualified professionals.
