## What is MiSensorKit?

MiSensorKit is a multi-modal field recording application designed for iOS devices. It enables synchronized capture of multiple sensor streams within a single recording session, making it the ideal portable tool for building rich multi-modal datasets in the field.

CAPTURE MULTIPLE MODALITIES

RGB frames saved as high-resolution JPEGs (up to 1024px)
LiDAR depth maps stored as UInt16 millimeter buffers
Full camera intrinsics and 6-DoF extrinsic pose logged every frame as JSON
Real-time 3D body skeleton tracking with joint positions via ARKit
Front-facing selfie camera capture
Gaze estimation and eye tracking data
GPS location with latitude, longitude, altitude, speed, heading, and accuracy metrics
IMU data including accelerometer, gyroscope, fused attitude (roll/pitch/yaw), and gravity vector
Ambient light intensity and color temperature estimates
Barometric pressure readings synchronized with every frame
FLEXIBLE RECORDING SETUP

Choose which modalities to record, configure sampling frequency from 1 to 60 Hz, and select output resolution from 224 to 1024 px. A built-in preflight check alerts you to missing permissions or hardware limitations before you start. Monitor sensor status, live FPS, stream health, and session size in real time while recording.

BUILT-IN DATA VIEWER

Browse and inspect recorded sessions directly on your device. Scrub through individual frames to view RGB images, depth maps, camera metadata, skeleton data, and sensor readings — without needing to transfer files to a computer.

EXPORT AND SHARE

Export any session as a ZIP archive directly from the app, or share the raw folder via Files and AirDrop. A session summary sheet appears automatically after each recording with key statistics and one-tap sharing options.

STRUCTURED OUTPUT FORMAT

Each recording session creates an organized folder structure with separate directories for RGB, depth, camera pose, skeleton, GPS, IMU, and metadata — ready for your processing pipeline.

REQUIREMENTS

iPhone or iPad with LiDAR sensor (required for depth recording only)
iOS 26.0 or later
Designed for researchers and developers who need a portable, easy-to-use tool for multi-modal data collection without external hardware or complex calibration setups.


## Version history (last 4 releases)

### 1.3 — 2026-05-25

- Fixed the bugs in the option Zip&Share.
- Changed the default app options.

### 1.2 — 2026-04-16

- Fixed IMU yaw drift during long recordings — orientation data now stays accurate over multi-minute sessions
- Raised minimum iOS requirement to iOS 17

### 1.1 — 2026-04-02

Version 1.1 — MiSensorKit

Live Sensor Monitoring
IMU and GPS now stream live in the Monitor tab at all times — no recording required. View accelerometer and gyroscope readings on all three axes, plus full GPS telemetry including latitude, longitude, altitude, speed, and heading.

Selfie + World Tracking
On A12 and newer devices, the selfie camera can now be combined with camera pose recording simultaneously. Face tracking and world-space positioning run together in a single session.

Expanded Modality Flexibility
Camera Pose and Metadata can now be recorded alongside any camera mode — front, rear, or selfie. GPS and IMU are always combinable with any configuration.

Location Permission
Location access is now requested at launch following Apple's recommended flow, so GPS is ready before your first recording.

Bug Fixes & Reliability
Fixed a data race in pressure and GPS snapshot reads during high-frequency capture. Fixed a finalization edge case where the last frame's writes could be missed on stop. Fixed a picker warning in the session browser. Improved logging under the MiSensorKit subsystem.

### 1.0 — 2026-03-19
