Craft video data for physical AI
Capture craft sequences that preserve material changes, tool choices and fine hand movements without claiming measurements the video cannot provide.
Craft work offers a close view of how people adapt movements to materials. Paper, fabric, clay and small components behave differently, and the same goal can be achieved through several techniques. Define which craft, material state and operation the model needs to observe rather than combining unrelated activities under a broad handmade label.
The most useful sequence usually includes a recognizable starting state, the meaningful transformation and a visible result. A beautiful finished object does not explain the procedure. Keep the ordinary adjustments and pauses that show how the maker responds when a material shifts or an alignment needs correction.
Tasks to include in the brief
Arranging components
Show choosing and positioning approved pieces before assembly. State whether the task concerns object selection, relative arrangement or the order in which the pieces are handled.
Folding and shaping
Capture a defined paper, fabric or other permitted material transformation. Include the initial edges and the final shape so a viewer can interpret the action without relying on a verbal claim.
Joining materials
Record an established, approved joining step with the relevant hands and contact area visible. Specify whether the interest is positioning, tool use or the sequence around the join.
Checking and adjusting
Capture a maker comparing the current arrangement with an approved reference, then making an ordinary correction. Distinguish visible adjustment from a claim that the finished piece meets a technical specification.
Capture requirements
- Frame fine movements at a scale where the relevant material features remain visible. Fingers can conceal a fold or join, so test the angle on a short sample first.
- Record material type and starting condition as contributor context when known. Visually similar materials may differ in stiffness or texture in ways the video cannot reliably identify.
- Vary approved colors, shapes, dimensions and work surfaces deliberately. For a controlled comparison, keep the operation consistent enough that material variation does not become an entirely different task.
- Show the final arrangement from the capture viewpoint. Preserve a natural retry or unfinished result, but do not ask the maker to waste materials or perform unfamiliar hazardous techniques.
Useful annotation layers
- Actions may include select, align, fold, press, position, join and adjust. Agree whether repeated small movements form one task interval or distinct actions.
- Separate visible descriptions from maker-supplied terms for tools, materials and techniques. Domain-specific names can require expert validation rather than a generic visual label.
- A text annotation does not measure material stress, bond strength, geometric tolerance or tactile feedback. Precise hand pose and contact trajectories need a dedicated measurement or annotation method.
Permissions, boundaries and exclusions
- Obtain approval for designs, patterns and customer commissions shown in the recording. Avoid private reference images, order information and unrelated screens on the workbench.
- Exclude unfamiliar blades, hot tools, powered machinery or chemical processes from an ordinary capture task unless a separately authorized recording plan covers them.
- The camera must not obstruct the maker or encourage a risky repetition. An obscured operation is a capture limitation to solve through planning, not a reason to change safe technique.
