Stereo Office Mailroom and Document Handling Data

It is first-person video of a person doing office paper work, recorded from their own point of view with two calibrated cameras and with hand pose and sensor streams alongside. The tasks are the four rows the site’s catalog lists in Office & Professional Services: opening, sorting and distributing incoming mail and preparing outgoing letters and parcels; sorting documents, labelling folders and filing them in cabinets in order; feeding pages into a scanner, naming and saving the files and refiling the originals; and loading paper, sending documents to the printer and collecting and collating the output. Stereo describes the capture, and MCAP describes the container. They are separate choices.

The site does not state that stereo is already running on these rows. The catalog lists a head-mounted phone or a multiview rig as the capture setup. Stereo applies only through the site’s general stereo offer: a stereo pair is a capture choice agreed in the skill spec and confirmed on a Spec Pilot. The data is human capture by paid, consented contributors, not robot or teleoperation data. Firsthand is not affiliated with Foxglove or the MCAP maintainers.

Four, all in Office & Professional Services under Office & IT, in the catalog data file lib/commercial-catalog-data.ts. The catalog lists examples for the environment: a corporate office, a co-working space and a reception area, with desk work, printing, filing, scanning, a coffee machine and mail handling. "Mail handling" is described as opening, sorting and distributing incoming mail and preparing outgoing letters and parcels, is rated Easy and is listed as Available on request. "Filing" is described as sorting documents, labelling folders and filing them in cabinets in order, is rated Easy and is listed as Available on request.

"Scanning" is described as feeding pages into the scanner, naming and saving the files and refiling the originals, is rated Easy and is listed as Available on request. "Printing" is described as loading paper, sending documents to the printer and collecting and collating the output, is rated Easy and is listed as Available on request. All four list a head-mounted phone or a multiview rig as the capture setup. The site says nothing further about what Available on request means in volume, hours or delivered stereo footage, so this page claims none, and what applies to a given order is confirmed when you request the quote. The first table below reproduces the rows as the catalog states them.

Three rows in the Office Document Station environment sit next to this work. "Sort into folders" is described as sorting documents into labeled folders, is rated Easy and is listed as Available on request. "Staple + collate sets" is described as collating multi-page sets and stapling each, is rated Easy and is listed as Available on request. "Stuff + seal envelopes" is described as inserting documents and sealing envelopes, is rated Medium and is listed as Available on request.

All three list a multiview rig with handheld grippers as the capture setup, which differs from the head-mounted phone or multiview rig on the four main rows. They are context only: this page builds nothing on them, and the egocentric mailroom and envelope pages are where they are treated. The catalog examples for that environment are a printer and tray, binders, a stapler, a label maker and mailers.

The egocentric mailroom and document handling page is the closest neighbour. It covers the same mail, filing, scanning and printing rows together with the Office Document Station rows, and it treats capture as egocentric. This page narrows to the four Office & Professional Services rows, as stereo capture agreed through the general stereo offer, and goes further into the stereo pair, the MCAP container and the failure modes at a desk, a cabinet and a scanner.

The egocentric office task page is wider: it covers desk work across the office environments and mentions a calibrated stereo rig as part of the general egocentric stream set rather than as its topic. The printer and shredder page covers two Office Document Station rows, "Load tray + clear jam" and "Shred documents", and the envelope stuffing page covers "Stuff + seal envelopes" and "Pack + tape mailer". None of those four pages centres stereo capture of the mail, filing, scanning and printing rows. The comparison table below sets them side by side.

Paper work is about where the hand, the sheet and its destination sit relative to one another: how far an envelope is from a tray, where a folder sits among its neighbours in a cabinet, how a page meets a scanner feed. A stereo pair recovers depth from the calibrated frame pair rather than from a standalone depth sensor, so the item, its destination and the hands share a frame.

The site gives no depth accuracy figure and no label for a sorted pile, a filed folder, a saved scan or a collated output, so whether those are resolvable in depth is Not stated. Capture at your own facility is listed as not offered.

The catalog states one capture setup for all four rows: a head-mounted phone or a multiview rig. The site describes two stereo setups and does not say which one an office order uses. The hard-environments stack is a global-shutter 4K/60 head camera with a 120° lens, two 1080p/60 wrist cameras, a depth sensor at 848×480 and 30 fps, and 200 Hz 6-DoF IMUs. The off-the-shelf stereo head rig, dataset 06, is dual fisheye cameras at 1080p per eye, a 62 mm baseline, per-unit calibration, a 9-axis IMU and hand-tracking output.

Which rig, resolution and streams a mail, filing, scanning or printing order uses is Not stated on the site, and the third table below sets what is stated beside what is not. Intrinsics and extrinsics are re-solved at the start and end of every session, and streams are hardware-triggered onto one clock with a 2.0 ms cross-stream ceiling. The catalog states that a multiview rig adds synchronized third-person angles when the spec asks for them, and wrist cameras give a closer view of the hands. The site does not state an office lighting setup, so lighting is Not stated and is agreed in the skill spec.

MCAP is an open source container file format for multimodal log data, supporting multiple channels of timestamped pre-serialized data. It is serialization-agnostic, so messages can be Protobuf, DDS (CDR), ROS, JSON and more. Its design is row-oriented and append-only, it stores schemas alongside the data, and it offers an optional index plus optional LZ4 or Zstandard chunk compression.

Reader and writer libraries exist for C++, Go, Python, Rust, Swift and TypeScript, and the mcap CLI can inspect, merge and split files. The foxglove/mcap repository is MIT-licensed; that is the MCAP project’s licence, not the licence of a Firsthand delivery. The MCAP hub page and the glossary entry cover the format in full.

Firsthand offers MCAP delivery, and dataset 06 is stated as shipping as MCAP. For office paper work the site states hand pose, depth recovered from the stereo pair, IMU, contact events, action segments and per-frame instance masks elsewhere. What it does not state is which of those are channels in an MCAP file, how they are named, what encoding they use or at what rate.

No topic name, message schema or rate is stated on this page, and none should be assumed. Name the streams that matter in the skill spec and confirm them on a Spec Pilot batch. The fourth table below sets each stream beside what the site states about it.

Hand occlusion of thin items is the first risk. Lifting one sheet from a stack, feeding a page and tucking an envelope flap put the fingers under or behind the paper, and a hand reaching into a printer is hidden from the head camera. The visibility flag on each joint is the answer the site gives for hidden fingers, contact events mark when a hand meets an item, and a spec can ask for wrist views so a grip the head camera loses is still recorded. The site states no page-edge, stack-height or fold label, so what counts as one sheet or a finished stack is written into the spec.

Reflective and cluttered surfaces are the second. The site notes that wet and reflective surfaces degrade active-stereo depth in its kitchen dataset, and names reflective surfaces and clutter as cases where a single camera struggles in hard environments. Whether a glossy printer or scanner surface, a crowded desk or a full cabinet behaves the same on a stereo pair is Not stated. The site ships per-frame depth confidence maps for its kitchen captures, and whether an office order ships them is Not stated, so ask in the spec.

Calibration is the third, because stereo depth is only as good as the rectification behind it: calibration is measured at the start and end of every session under a 0.28 px RMS gate. An episode is also rejected when the manipulated object is out of frame for more than 15 percent of it or an undocumented bystander appears, and a reject log ships with every batch. Force and tactile readings are not among the listed streams.

Office paper work chains steps that look alike on camera: opening one envelope and then the next, sorting one item into a slot and then another, filing one folder and then the next, feeding one page and then the next. Action segments carry start, end, verb and noun, so the spec decides where one segment ends and the next begins, and which object is the noun.

The site states no episode length, no segment count and no per-item label for these rows. Whether an episode is one piece of mail, one folder, one scanned set or one print job is set per program. Put that boundary and the verbs you expect into the skill spec, and check them on the Spec Pilot before you scale.

For every delivered episode the site states that faces, plates and screens are blurred irreversibly, speech is scrubbed of names, addresses and card numbers, any identifiable un-consented person goes to human review, and footage that cannot be de-identified is discarded. The anonymization page adds that the same pass covers legible screens and documents, badges, and spoken identifiers, including forms and mail that would leak names, addresses or account data, and that a human reviewer confirms the result before anything ships.

An office can have coworkers in frame, and who may be in frame is agreed in the spec. The site states no office, company or client name, no printer, scanner or software brand, and no page count, document count, task time, throughput or error rate for these rows. Each of those is Not stated. How the site handles a screen in a cluttered desk shot beyond the blurring above is Not stated.

Off-the-shelf covers what is already in stock: the stereo category lists the stereo datasets and hand-tracking video, and only dataset 06 is stated as MCAP. This page does not claim an off-the-shelf dataset of mail handling, filing, scanning or printing, so this is custom collection: custom collection at scale through a network of thousands of capture providers, for a consistent, recurring data flow to labs.

Where coverage is deep, the median time from signed spec to first validated batch is a median of 48 hours; where it is thin, turnaround runs three to four weeks. The site does not say which speed applies to a stereo office order, so ask when you request the quote. Collections are billed per validated hour.

Describe the tasks and their order, the kinds of mail and documents involved, where each one ends up, what counts as a finished step, and the variation your pipeline is missing. Then name the streams you want in the file, the topic naming and message encoding your reader expects, whether calibration ships inside the file or beside it, and whether MCAP is the only delivery or sits beside RLDS, LeRobot or WebDataset.

Most programs begin with a Spec Pilot, a small first batch that proves the spec and accept criteria on real footage before you scale. The fifth table below shows what each spec element decides.
