Motivation:
- Is it possible to infer the persons goals by analyzing their eye fixations?
- Eye movements can reveal complex cognitive states of mind
- Analyse Visual Behavior
- Closed World Vs Open World Settings
- Prediction of Search Targets using Stationary Eye Tracker
Hardware Mobile eye tracker
Data
- Data collected from ~18 participants
- Virtual objects
Data Preprocessing
- Implemented computer vision algorithms to preprocess data
Feature extraction
- Used pre-trained network like resNet-50 to extract features from data
Approaches
- Implemented various Machine learning/Deep Learning algorithms to predict the search target
