## What is OW Recorder?

A hands-free video recording application designed for egocentric data capture. Mount your iPhone on a standard head strap and record hands-free.

Account Required. Access is invite-only — a valid invite code is required to create an account. Video recordings are uploaded to your organisation's private cloud storage, and your recording history is stored in a private, user-specific database.

Key Features:

Real-time hand detection powered by Apple's Vision framework tracks hand positions in the video frame to enhance egocentric dataset quality and contextual understanding.

Research session recording captures synchronized motion sensor data (accelerometer, gyroscope, and magnetometer at 100 Hz), 6-DoF head pose estimation, hand pose landmarks (21 joint positions per hand), and camera calibration data (focal length and lens parameters) — packaged as a session ZIP file alongside the video for egocentric dataset collection.

Integrated voice commands enable seamless, hands-free control of recording sessions — simply say "start recording" or "stop recording" while the device is mounted. Torch control via voice is also supported.

Captured videos can be uploaded to your organisation's private cloud storage with a single tap, ensuring a streamlined and efficient data collection workflow.

Background upload support — start an upload and switch to another app; the video keeps uploading and you receive a notification when it's complete.

Supports flexible recording configurations including adjustable resolution (1080p recording at 30 or 60 fps, and 4K recording at 30 fps on capable devices). A minimum zoom of 0.5x is available on multi-lens devices (iPhone 11 and later) for an ultra-wide field of view.

Tag each recording with an environment label — Living Room, Kitchen, Bed Room, Outdoor, Garden, and more — to organise your data collection by location context.

Device Compatibility Check: instantly see which camera lenses, resolutions, and frame rates your specific device supports before you begin recording.

Your complete recording history — including video names, durations, timestamps, environment tags, and upload dates — is accessible in-app and can be exported as a CSV file.


## Version history (last 5 releases)

### 3.3 — 2026-06-25

NEW IN V3.3:
1. Environment Sound Toggle — a new speaker icon in the recording
   controls lets you enable or disable ambient audio capture in the
   recorded video. On by default. Cannot be changed mid-recording.
2. Frame rate (FPS) is now stored per recording in your history and
   included in session metadata.
3. Upload is now blocked if the recorded video does not meet the
   minimum frame rate threshold, with a clear prompt to retake.

### 3.1 — 2026-05-23

NEW IN V3.1:
Research Session Recording

• Synchronized IMU recording: captures accelerometer and gyroscope 
  data at 200 Hz alongside every video
• Hand pose landmark export: 21-joint hand keypoints recorded 
  per frame and included in session data
• Camera intrinsics (focal length and lens parameters) captured per session
• All session data packaged as a ZIP file and uploaded alongside 
  the video for research dataset workflows
• Session metadata includes device model, resolution, FPS, 
  timestamps, and voice-trigger flag
• Improved audio: voice confirmations ("Started"/"Stopped") 
  no longer get cut off
• Video preview on upload screen now correctly fills portrait width

### 3.0 — 2026-05-04

• Added a dedicated zoom slider (pinch zoom is still supported)
• Improved sign-up validation with clearer required-field feedback
