Overview

This project investigates an adaptive Virtual Reality (VR) system that integrates eye-tracking data from the HTC Vive Focus 3 (Eye Tracker add-on) with physiological signals from a smart ring (ex. COLMI R02) or a smart watch to support stress reduction and emotional self-regulation.

Users begin in a busy, noisy city VR environment and, to decrease stress and to stabilize focus, the world gradually transitions into restorative nature scenes, such as a calming forest or ocean with background sounds. Eye metrics (gaze fixation, pupil dilation, blinks) and biosignals (HR, HRV, SpO₂) are fused to estimate arousal. The smoother and calmer the signals, the faster and more positive the transition, creating an engaging form of biofeedback.

 

Tasks

– Course Project

  • Integrate eye tracking (gaze, pupil size) from Vive Focus 3 via OpenXR.
  • Stream biosignals (HR/HRV/SpO₂) from COLMI R02 via BLE.
  • Simple fusion model with weighted rules
  • Implement threshold-based transitions from city → (park) → nature.
  • Small demo test with 2–3 users.

 

–  Bachelor Thesis

  • Develop a fusion model combining gaze and biosignals into an arousal index.
  • Build a multi-stage environment: city → (park) → nature.
  • Apply positive nudging: calming signals speed up transition.
  • Run a pilot study (5–10 users) with questionnaires + HRV/pupil metrics.

 

– Master Thesis

  • Create a robust multimodal framework with personalized baselines.
  • Implement two conditions: forest vs. ocean transitions.
  • Run a controlled study (larger participants), comparing biofeedback vs. no-biofeedback.

 

Required Skills

  • Unity development with OpenXR.
  • Eye-tracking data handling (gaze, pupil, blink).
  • BLE integration for smart rings/watch.
  • Signal fusion & real-time processing.
  • Interest in VR design, affective computing, environmental psychology.
