[GSOC-25] Eye-Tracking Calibration Interface – Standalone & RUXAILAB Integration

[jvJUCA]

This PR adds the eye-tracking calibration interface as a standalone service, used during usability tests in RUXAILAB, with support for sending calibration data via webhook:

• Standalone Eye-Tracking Interface

  • Allows calibration without requiring RUXAILAB login
  • Video device selection (webcam)
  • Capture of iris points using calibration pattern or mock pattern
  • Video recording during the calibration session

• Integration with RUXAILAB via Webhook

  • Receives test configuration from RUXAILAB (number of points, samples per point, colors, etc.)
  • Sends calibration data (iris points, predictions, video) automatically to RUXAILAB

• UI and UX

  • Toolbar (Toolbar) and blink threshold panel (BlinkTresholdCard)
  • Canvas to visualize calibration points and progress
  • Full calibration flow: capture → preview → data submission

• Routes and Functionality

  • Removed authentication for standalone usage
  • predict endpoint for gaze tracking capture
  • Dynamic configuration via query parameters when integrated with RUXAILAB
  • Auto-generated mock patterns when needed

Key Changes

src/views/DoubleCalibrationRecord.vue

• Initialized calibration pattern (mock or real)
• Captures and stores iris points
• Sends calibration data to RUXAILAB via webhook

src/views/CameraConfiguration.vue

• Webcam selection and restart with chosen device
• Dynamic flow for standalone or RUXAILAB integration
• Camera state management and real-time face detection

src/store/calibration.js

• New state and mutations for calibration configuration
• Mock pattern generation for calibration points
• Calibration data submission via Vuex actions

Other

• Adjustments in auth.js, store/auth.js, and router/index.js for standalone use
• UX improvements in calibration interface

Benefits

• Independent interface for eye-tracking calibration
• Automated data submission to RUXAILAB
• Responsive UI compatible with different webcams
• Reliable capture and recording of calibration points
