ARETT

ARETT acquires and analyzes eye-tracking data from the Microsoft HoloLens 2 within Unity 3D to quantify gaze accuracy and precision for augmented reality research.

Key Features:

• Integration with Unity 3D: Leverages Unity 3D for embedding eye-tracking routines and scripting support.
• Microsoft HoloLens 2 eye tracker: Uses the built-in eye tracker of the Microsoft HoloLens 2 for gaze data acquisition in AR scenarios.
• Data acquisition scripts: Provides scripts for acquisition of eye-tracking data from the HoloLens 2.
• R package for analysis: Includes an R package for comprehensive eye-tracking data analysis.
• Spatial accuracy and precision evaluation: Implements evaluation of spatial accuracy and precision of gaze estimates under varying conditions.
• Validated performance: Demonstrated angular accuracy of 0.83 degrees and precision of 0.27 degrees at rest in a 21-participant study.

Scientific Applications:

• Cognitive and educational research: Supports studies in cognitive and educational sciences using gaze metrics in AR.
• Visual attention studies: Enables investigation of visual attention in virtual and augmented reality environments.
• Gaze-based interaction and rendering optimization: Supports development and assessment of gaze-driven interaction techniques and rendering optimization in AR.
• User behavior and content delivery: Facilitates research to understand user behavior and optimize AR content delivery.
• Interactive system development: Aids development of interactive AR systems that leverage eye-tracking data.

Methodology:

Provides scripts for eye-tracking data acquisition, an R package for eye-tracking data analysis, and procedures to evaluate spatial accuracy and precision of gaze estimates.
