Keyboard Shortcuts

This page covers the CLI viewer window (the OpenCV display shown while python MindSight.py runs). The desktop GUI application itself defines no keyboard shortcuts.

CLI Mode Controls

These keys are active in the OpenCV display window while MindSight is running.

Key Action
Q Quit video or webcam playback (closes the window and ends the run)
Any key Close a single-image result window and exit

On-Screen Overlay Legend

The annotated output frame uses the following visual conventions:

Visual Element Meaning
Coloured arrow (per person) Gaze ray projected from the eye/face origin in the estimated gaze direction
Thin coloured box around person Person detection bounding box
Thick box labelled JOINT Object currently under joint attention (all/quorum persons looking at it)
Gold box labelled LOCKED Object that a person's gaze has locked onto (dwell threshold met)
Green-tinted ray tip Ray endpoint was snapped to the nearest object (adaptive_ray: snap)
Dwell arc at gaze origin Partial progress toward gaze lock-on. The arc is centred on the person's gaze-ray origin (the eye/face point), not the object, and fills as dwell frames accumulate
Teal circle labelled CONVERGE Gaze-tip convergence point where multiple persons' rays meet within tip_radius pixels

Dashboard Composite

By default MindSight composes each annotated frame into a wide dashboard layout [ left panel | video | right panel ], rendered with matplotlib. It is not a corner HUD overlaid on the video -- the panels sit beside the video and widen the output frame.

Region Contents
Left panel Run-time info: FPS, detection count, active phenomena, JA status, and accuracy-feature summary
Centre The annotated video frame (gaze rays, boxes, badges, convergence markers)
Right panel Per-person gaze state: track ID / participant label, current hit target(s), lock status, plus phenomena-specific lines (mutual gaze pairs, social referencing, gaze leader, etc.)

Pass --no-dashboard to skip dashboard composition entirely; the window (and any saved video) then shows only the raw annotated frame.
