Avatar pose preview

Body and hands come from the pipeline output (Gemma 3 27B glosses, agreement and OOV handling). Head movement, mouth, blinks and brows come from MediaPipe face tracking of the source videos, matched frame by frame: TİD Sözlük signs and the selected fingerspelling alphabet.

Arm depth is estimated from fixed bone lengths. Elbows, wrists and forearm twist are kept inside human joint ranges, so a few hand orientations are approximations of the data. “Face off” shows the same signing with a still face, for comparison.

Pause on any frame (‹ › step one frame) and drag the avatar sideways, or use the View slider, to look at the sign from any angle. Zoom with the + and − buttons, the mouse wheel or a pinch; the wheel and pinch zoom towards where you point, and when zoomed in you can drag up or down with the mouse. Keys: space play/pause, comma/period step, arrow keys turn, + and − zoom.
