Runtime Models

`tobii_pytracker.analyze.DataLoader`	Main analysis orchestrator.
`tobii_pytracker.analyze.HeatmapAnalyzer`	Generates gaze heatmaps and overlays them over screenshots.
`tobii_pytracker.analyze.FocusMapAnalyzer`	Focus Map Analyzer — shows areas NOT looked at (inverted heatmap).
`tobii_pytracker.analyze.FixationAnalyzer`	Detects and visualizes gaze fixations from time-series gaze data.
`tobii_pytracker.analyze.SaccadeAnalyzer`	Calculates saccade metrics (dx, dy, dt, amplitude, velocity, acceleration) from gaze data.
`tobii_pytracker.analyze.EntropyAnalyzer`	Computes gaze entropy and dispersion measures (Shannon entropy and Convex Hull area).
`tobii_pytracker.analyze.ClusterAnalyzer`	Performs clustering on gaze coordinates.
`tobii_pytracker.analyze.ConceptAnalyzer`	Defines AOI-like (Areas of Interest) concepts from clusters and computes engagement statistics per concept.
`tobii_pytracker.analyze.ScanpathsAnalyzer`	Analyzes sequential transitions between fixations to characterize scanpaths per slide, set, or globally.
`tobii_pytracker.analyze.VoiceTranscription`	Transcribes and aligns voice data with gaze events.
