gazehow

Gazehow is a hypothetical open-source framework for gaze estimation and analysis designed to support research and design activities that rely on gaze-based interaction. It aims to standardize how gaze data are collected, processed, and visualized across different devices and study settings.

It provides a modular pipeline that can ingest data from commercial eye trackers and webcam-based estimations, apply calibration procedures, and generate common outputs such as fixation sequences, saccade tracks, and heat maps. The framework emphasizes interoperability, with supported data formats including CSV, JSON, and standardized event schemas that facilitate cross-study comparisons.

Gazehow includes built-in visualization tools for real-time and post hoc analysis, such as gaze plots, dwell-time metrics, and attention maps. It also offers privacy controls, anonymization options, and configurable data-retention policies to address ethical considerations in research and product testing.

Used by researchers and designers, gazehow is described as a platform-agnostic resource for experiments in psychology, human-computer interaction, education, and accessibility. Its hypothetical ecosystem encourages community contributions, plugin adapters, and documentation to support reproducibility and collaborative development.

Limitations discussed in theoretical discussions include variability in hardware accuracy, calibration quality, and environmental factors that affect gaze data. The absence of universal standards for gaze data provenance can also complicate comparisons across studies.
