9DOF Motion Tracking Sensors

Accurate 3D Motion Sensing for Professional and OEM Applications

2M Engineering develops IMU-based motion capture solutions for applications where accurate, real-time tracking of human movement is essential. Our motion sensing technology supports professional use in medical rehabilitation, research, sports performance, ergonomics, and VR/AR applications.

We design wearable motion capture systems that deliver reliable orientation and raw sensor data in real-world environments — from controlled laboratory settings to home rehabilitation and field use.

What We Enable

Motion capture is not only about visualizing movement. In professional and medical contexts, it must deliver repeatable, low-latency and interpretable data that can be trusted for analysis, feedback and decision-making.

Our IMU-based motion capture solutions enable:

real-time 3D orientation tracking of body segments
raw motion data capture for advanced analysis
scalable systems from single-segment to full-body tracking
use in environments where camera-based systems are impractical

We focus on wearable, camera-free motion tracking that works anywhere the user moves.

Technical Foundation: IMU-Based 9DOF Motion Tracking

Our motion capture systems are built on 9DOF inertial measurement units (IMUs) combining:

accelerometers (linear acceleration)
gyroscopes (angular velocity)
magnetometers (magnetic field reference)

Using advanced sensor fusion algorithms, these signals are combined into stable 3D orientation data (quaternions) or provided as raw sensor streams for custom processing.

Reference Platform: QSense Motion

A concrete implementation of our motion capture approach is the QSense Motion platform — a mature, CE-certified wearable motion sensing system used by OEM partners, researchers and professional users.

QSense Motion consists of:

compact, waterproof (IP67) wireless IMU sensors
real-time BLE data streaming
PC and mobile tooling for recording and visualization
open APIs and SDKs for integration

The platform supports modular configurations, ranging from a single sensor on a limb to multi-sensor full-body tracking setups.

Real-Time Data & Open Integration

Depending on application needs, our motion capture solutions can provide:

real-time orientation data (quaternions)
raw accelerometer, gyroscope and magnetometer data
synchronized multi-sensor data streams

Open interfaces allow straightforward integration into:

research software environments (e.g. MATLAB)
game engines and VR/AR platforms (e.g. Unity)
custom medical or training applications

This flexibility enables OEM partners to fully control how motion data is processed, visualized and interpreted.

Designed for Real-Time and Low Latency Use

Many applications — especially VR, AR and rehabilitation — require low latency and stable real-time performance.

Our motion capture systems are optimized for:

low-latency wireless communication
real-time feedback applications
synchronized multi-sensor operation

This makes them suitable for immersive training, serious gaming and interactive rehabilitation environments.

Applications

Our IMU-based motion capture technology is used across a wide range of domains.

Medical & Rehabilitation

Used for physical therapy, stroke rehabilitation, prosthetics and clinical research — in both clinical and home settings. Wearable motion capture enables objective progress tracking without camera infrastructure.

Research & Biomechanics

Provides accurate motion data for movement analysis, ergonomics and human factors research, supporting both exploratory studies and long-term data collection.

Sports & Performance

Used to analyse technique, posture and movement efficiency in professional and elite sports, enabling performance optimization and injury prevention.

VR, AR & Serious Gaming

Supports immersive environments where accurate body movement tracking is required without external cameras.

OEM & Custom Motion Capture Solutions

Because we own the complete hardware and software stack, we can:

customize existing motion capture platforms
adapt form factors or attachment methods
integrate sensors into garments or equipment
develop fully custom IMU-based motion tracking solutions

This allows OEM partners to create motion capture products that are fully optimized for their specific application, rather than adapting generic systems.

Selected Motion Capture Projects

Our motion capture expertise is demonstrated through projects such as:

full-body motion tracking suits for VR rehabilitation
hand and finger motion tracking solutions
wearable sensor gloves for prosthetics
long-term raw motion data loggers
