Firsthand vs the public datasets.

The dimensions that decide most robot-learning projects. Full breakdowns on each comparison page.

Dimension	Firsthand	Ego4D	EgoDex	EgoScale
Hand pose	3D, handJoints[2][21][3], metric, in the head-camera frame	No manipulation-grade 3D hand pose	Strong 3D hand pose	Not manipulation-grade 3D hand pose throughout [VERIFY]
Action labels	Frame-accurate action segments (verb, noun, ns timestamps)	Dense narrations and task benchmarks; not frame-accurate manipulation segments throughout [VERIFY]	Task/annotation scheme per the dataset release [VERIFY]	Scaling-study labeling [VERIFY]
Sync	Hardware-triggered; median 1.12 ms, 2.0 ms ceiling, drift written to metadata	Not hardware-synchronized to a sub-2 ms ceiling [VERIFY]	Not specified as sub-2 ms hardware sync [VERIFY]	Not a sub-2 ms hardware-sync guarantee [VERIFY]
Commercial use allowed	Yes	Permitted under the Ego4D license terms [VERIFY]	No — non-commercial, no-derivatives	[VERIFY]
Cost	Per validated hour, quoted per engagement; free sample pack, no form	Free under license terms	Free for non-commercial research	Per the release [VERIFY]

Figures marked [VERIFY] are confirmed against each dataset's official sources before publishing.
