Object Category Understanding via Eye Fixations on Freehand Sketches
Summary
Researchers found consistent eye gaze patterns in freehand sketches, even with varied depictions. This consistency allows predicting sketch categories and understanding object parts from gaze data.
Area of Science:
- Computer Vision
- Cognitive Science
- Human-Computer Interaction
Background:
- Eye gaze fixation studies are common for photographic images.
- Freehand sketches are understudied in gaze fixation research.
- Sketches present unique challenges like depiction variability and content sparsity.
Purpose of the Study:
- To analyze gaze fixation patterns in freehand sketches.
- To investigate multi-level consistency in sketch viewing.
- To explore applications of gaze data for sketch analysis.
Main Methods:
- Conducted a free-viewing gaze fixation study.
- Analyzed 3904 freehand sketches across 160 object categories.
- Examined fixation sequences within and across sketches and categories.
Main Results:
- Demonstrated marked consistency in fixation sequences.
- Showcased consistency within sketches, across categories, and grouped categories.
- Highlighted the significance of this consistency despite sketch variability.
Conclusions:
- Gaze fixation consistency in sketches can be exploited for computational tasks.
- Developed models to predict sketch category from fixation sequences.
- Developed models to predict part-labels underlying fixations on objects.
- Encouraged further research into gaze-based studies of sketch representations.
