Egocentric Buttons, Zippers and Fasteners Data

Egocentric buttons, zippers and fasteners data is first-person video of a person closing or securing something with a fastener, recorded from their own point of view with synchronized sensor streams alongside. On this site the fasteners are the ones in four catalog rows: buttons and snaps, a zipper, a lace through eyelets and a cable strap.

This page is about buying a custom collection of those demonstrations. It is narrower than a general deformable-object collection and than a sewing collection. The subject here is the fastening step itself, how it is specified and how it is labeled so a training pipeline can use it.

Four rows count on this page, and all four sit in the Deformables & Textiles Bench, in the Manufacturing & Workshops sector. The catalog describes the environment as a cloth-and-cable bench with garments, towels, cables, form boards and bags.

"Fasten buttons/snaps" is described as "Fasten a row of buttons or snaps." and is rated hard. "Thread lace eyelets" is described as "Thread a lace through eyelets." and is also rated hard. "Open/close zipper" is described as "Start and run a zipper closed." and is rated medium. "Coil + Velcro cable" is described as "Over-under coil and strap a cable." and is rated medium.

The last row is a cable task. Its name includes Velcro and its description says to strap a cable, so it covers securing a cable rather than closing a garment. It is counted because the site lists it as a fastening row on the same bench, and the page says so plainly rather than stretching it into garment work.

All four use the capture setup "Multiview rig + handheld grippers" and are marked available on request, not ready to deploy. The first table below reproduces them as the catalog states them.

The same bench lists other soft-goods and cable tasks, and the site also lists sewing rows elsewhere. None of them is a fastener row, so none is claimed here. The second table lists the closest ones and the reason each is left out.

Folding, hanging, flattening and sock pairing handle fabric but do not close or secure anything. "Insert duvet cover" puts a duvet into its cover, which the description does not describe as fastening. "Route + clip cables" routes cables to a form board, a different cable task from strapping one. Sewing, hemming and tailoring rows join fabric with thread and are covered on the sewing page.

A sub-task that is not one of the four rows, such as a hook, a buckle or a drawstring, is not claimed here and is settled in a Spec Pilot.

A fastening step is small, and the hands cover most of it. Fingers disappear behind objects in manipulation, which is why 3D hand pose carries a per-joint visibility flag. In a button or zipper task the cloth is folded over the fingers for much of the attempt, so occlusion is the normal case rather than an exception.

Three further limits are already stated on this site. Instance masks for deformable objects are shipped per frame rather than propagated, which is what a shape-changing material needs. Metric depth on sub-centimetre parts is flagged rather than interpolated. Depth degrades on wet and reflective surfaces and is handled with per-frame confidence maps.

Whether a button, a zipper pull or an eyelet counts as a sub-centimetre part is not stated, and the site gives no mask accuracy figure for fasteners.

Each attempt is delivered as one episode, and a fastener task needs a decision up front about what one attempt is: one button, one full row, one zipper run, one lace threaded through every eyelet or one cable coiled and strapped. The site does not set that length, so the skill spec does.

Inside the episode, the synchronized streams run from start to end and action segments divide it into labeled spans. A zipper episode might open with seating the slider and close at the end of the run, and a button episode might run along the row, as the catalog descriptions read. These are illustrations of how a spec can cut an episode, not stated durations.

The instrumented tier is a head-mounted stereo rig that records first-person RGB, with a metric depth stream recovered from the calibrated stereo rig rather than from a standalone depth sensor, and 6-DoF IMU data at 200 Hz from head- and wrist-mounted sensors. The wider stack is ten streams: a 4K head camera, two wrist cameras, depth, IMU, 3D hand and body pose, instance segmentation and action labels, hardware-aligned under 2 ms.

The catalog lists the capture setup per row, and for all four fastener rows it is a multiview rig with handheld grippers. The site does not explain the grippers further. The site does not state a camera count, resolution or frame rate specific to fasteners. Force and tactile readings are not among the streams, and no robot or teleoperation data is captured.

Inside each episode, action segments divide the recording into start- and end-timestamped spans, each carrying start_ns, end_ns, verb and noun. For this task family a segment can be one step as written in the skill spec. The other standard fields are hand_joints and hand_visible for 3D hand pose, contact_events for the moment the hand meets an item, objects, and instance_masks, stored at the depth resolution of 848×480 so they line up with the depth stream.

Hand pose is delivered with 21 joints per hand and a per-joint visibility flag for occluded fingers. That is the label that carries how the fingers pinch a button, hold a slider or pull a lace. The site does not say whether a button, a zipper pull or a strap counts as the item in a contact event, so the spec is the place to settle what a contact event means for your task.

The site does not list a label for the fastener itself: no open or closed state, button count, zipper type, lace tension or completion score, and no contact force reading.

From signed spec to first validated batch, the timeline is a median of 48 hours where coverage is deep and three to four weeks where it is thin and contributors need to be recruited first. The site does not say which timeline applies to the bench, so ask when you request the quote.

The license is perpetual, irrevocable and worldwide, with the data buyer-owned and non-exclusive by default. Training, evaluating, fine-tuning and deploying models, including commercial ones, is permitted, and exclusivity is available as a separate term. The executed agreement controls. Collections are billed per validated hour, and the site states no price list or minimum order for this family. Capture at your own facility is listed as not offered.

Describe the fastening, the garment or cable it is on, the setting and the slips or variation cases your pipeline is missing. That becomes a written skill spec, quoted for reach, timeline and price before any capture begins, and most programs run a Spec Pilot first.
