Recording a session - Holos Docs

Starting a session

From the Holos Capture home screen:

Tap New Capture to open the session setup sheet
Enter a Name for the session (it defaults to today’s date)
Under Objects, select any trackable objects you want followed during the session
Tap Start

The app enters an immersive space and begins recording all active modalities simultaneously.

Modalities

Each modality captures a distinct data stream. All streams are timestamped and synchronized to the same clock.

Modality	Notes
Stereo video	Always active. Records left and right camera at 1080p.
Device pose	Always active. Records headset position and orientation at full frame rate.
Hand tracking	Active when hands are in frame. Records full joint skeleton for both hands.
Object tracking	Active only for objects selected when the session starts. See Tracked objects.
Transcription	On-device speech recognition. Produces timestamped transcript segments.
Location	Recorded once at session start.

During a session

A recording indicator is visible in the corner of your view while capturing
Tracked objects appear highlighted when the system has a lock on them
Transcription happens in real time; speak clearly if you want good captions

Stopping a session

Tap the Stop button to end the recording. The app will finalize all streams and package them into a session file. This may take a few seconds for longer recordings. Once finalized, you’ll be taken to the session review screen. See Uploading.
