DATA SAMPLE · EPISODE 20260917_133640
A real stereo segment,
split intoVerifiable data layer.
Below is actual binocular E2 footage 20260917_133640 (UID d36997d92fc9), duration 11 minutes 22 seconds. The device files contain only left and right eye, IMU, magnetometer, and 16 kHz stereo audio. The skeleton, mosaic, and color block in the upper right on the left and right eye views are post-processing estimates, not hand, pose, or depth output from this device. This clip is a 4 Hz preview and cannot be used as a training set. The actual measurements in this segment are 1600×1200@30 Hz and gyroscope approximately 798.9 Hz. The parameter table lists 1600×1200@30fps, IMU 800Hz, per-camera HFOV 139° / VFOV 111°, binocular spacing 65mm; the pinhole-estimated field of view is not the parameter table's specification.
SOLUTION
Stereo, inertial, and post-processing viewed separately
Training reads the 30 Hz raw footage from Camera0 and Camera1, as well as stereo_index.jsonl. Preview is only used to check whether the skeleton falls on the hands and whether wall markers are detected. The audio is device stereo, starting 97 ms later than the left camera's exposure start. This device has no head pose; the bottom angles are gyroscope integration and will drift. Nominal specifications are listed in the specification table below; this section only verifies this single capture.
The accelerometer and gyroscope are approximately 798.9 Hz. The magnetometer is 200 Hz. The accelerometer is 124 ms earlier than frame 0 of the left eye. The 1.5 ms in the calibration was not applied because there is no head pose to verify against.
PCM 16 kHz stereo. Packet 0 is 96.6 ms later than the left-eye exposure start. The player overlays it into the annotation clip at 97 ms.
Vision 21 points. Left hand green, right hand orange. Not the device OpenXR 26 joints, and no per-joint confidence.
Faces, distant human bodies, text with confidence reaching 0.40, bright screens, and blue wall markings. Very faint text on glass may still remain.
The top right is unrectified disparity, not a depth camera, and cannot be used as metric depth.

- The parameter table lists 2 RGB global-shutter cameras at 1600×1200@30fps, IMU 800Hz, per-camera HFOV 139° / VFOV 111°, binocular spacing 65mm. The original footage in this segment is 1600×1200@30 Hz, gyroscope approximately 798.9 Hz (consistent with 800Hz); the pinhole-estimated horizontal field of view is approximately 117°, not the parameter table's 139°. The measured baseline is 65.94 mm, while the parameter table lists 65mm.
Around 2:17, the cropped wall sign reads "SKYWORTH XR"; the full frame has used SKYWORTH. At 10:28, the same blue sign is blurred, and OCR at this second returns a low-confidence misread. The training file is on the data description page — do not train on this 4 Hz clip. This preview does not replace prototype acceptance testing in the nominal mode.
DATA SAMPLE · EPISODE 20260917_133640
One real stereo take,
split into layers you can check.
This is a real binocular E2 take, episode 20260917_133640 (UID d36997d92fc9), 11 minutes 22 seconds. The device files are the two eyes, IMU, magnetometer and 16 kHz stereo. The skeleton, mosaic and corner patch are later estimates, not device hands, pose or depth. This file is a 4 Hz preview and is not the training source. This take measures 1600×1200 at 30 Hz and about 799 Hz gyro. Source video matches the datasheet camera mode (1600×1200@30fps). Datasheet IMU is 800 Hz; per-camera HFOV is 139° and VFOV is 111°.
SOLUTION
Stereo, inertial, then estimates
Train on the 30 Hz Camera0 and Camera1 files, joined by stereo_index.jsonl. The preview only shows whether the skeleton sits on the hands and whether the wall mark is masked. Audio is the device stereo, 97 ms after the left-eye exposure start. This package has no head pose. The heading in the bar is integrated gyro and it drifts. Brochure figures are in the spec table. This block only checks this take.
HEVC 1600×1200 at 30 Hz. The calibration group is named tracking. Baseline is 65.94 mm. Inter-eye exposure-start difference is 198 µs at the median. A pinhole horizontal field is about 117°. Distortion was not applied. Datasheet HFOV is 139°, so this estimate is not the datasheet field of view.
Accel and gyro are about 798.9 Hz. Magnetometer is 200 Hz. Accel starts 124 ms before the left eye. The factory 1.5 ms alignment was not applied: there is no head pose to check it against.
PCM, 16 kHz, stereo. Packet 0 is 96.6 ms after the left-eye exposure start. The player applies 97 ms.
Vision, 21 points. Left is green, right is orange. Not the device OpenXR 26 joints, and there is no per-joint confidence.
Faces, distant people, text at confidence 0.40 or above, bright screens, and the blue wall mark. Faint glass lettering can remain.
The corner patch is unrectified disparity, not a depth camera, and not metric depth.
