VisME

VisME visualizes and analyzes high-frequency eye tracking data to explore microsaccade distributions and the effects of detection-filter parameter variation.

Key Features:

• Interactive Parameter Variation: Enables interactive adjustment of parametric values for microsaccade detection filters to evaluate parameter influence on microsaccadic behavior at individual and group levels.
• Brushing-and-Linking Techniques: Uses brushing-and-linking to extract and visualize microsaccade properties across space, time, and movement direction for linked multi-view comparisons.
• Multiple Analytical Views: Supports analysis at the levels of fixations, participants, trials, and test conditions for both individual and group data.
• Customizable Filters: Provides eye movement filters and visibility filters to tailor selection and detection criteria.

Scientific Applications:

• Natural Scene Viewing: Facilitates studies of microsaccade behavior during natural scene viewing to investigate visual processing and attention mechanisms.
• Parameter Sensitivity and Pattern Detection: Enables evaluation of how varying detection-filter parameters affect identification of consistent patterns and anomalies in eye movement data.

Methodology:

Combines interactive visualization techniques with advanced filtering algorithms, including parametric microsaccade detection filters and brushing-and-linking methods to extract and visualize microsaccade properties across space, time, and movement direction.
