Area of Science:

Human-Computer Interaction
Cognitive Science
Behavioral Psychology

Background:

Human interactions rely on interpreting behavioral cues like gaze to predict intentions.
Eye gaze is a crucial cue for understanding attention and intent in dyadic interactions.
Effective intention prediction facilitates adaptive behaviors crucial for successful joint actions.

Purpose of the Study:

To quantify how gaze patterns can predict a person's intention.
To investigate the predictive power of customer gaze cues for intended requests in a sandwich-making task.
To develop a model for real-time intention recognition based on gaze features.

Main Methods:

Utilized a dyadic sandwich-making scenario with a worker and a customer.
Extracted predictive features representing customer gaze patterns.
Developed and evaluated a support vector machine (SVM)-based model for intention prediction.

Main Results:

The SVM model achieved 76% accuracy in predicting customer ingredient requests based solely on gaze features.
Predictions were made approximately 1.8 seconds before the customer's spoken request.
Analysis of interaction episodes identified additional gaze patterns for potential model improvement.

Conclusions:

Gaze cues are a significant resource for understanding and predicting human intentions.
The findings inform the design of intelligent systems, such as assistive robots, for real-time user intention recognition.
Improved intention recognition can lead to more complex capabilities and enhanced user experiences in human-AI collaboration.
