Quick overview of features, applications and positioning
What makes QSense unique
QSense is designed as a professional-grade motion sensing building block, not a consumer IMU repackaged for serious use. Key differentiators include:
System-level calibration & drift control
QSense AutoCal automatically compensates gyroscope bias during verified sensor stillness, reducing drift over time without requiring user interaction. This improves long-term orientation stability in real-world use. > Read More
Low-latency, synchronized multi-sensor operation
QSense is built for real-time, multi-sensor setups with tight synchronization, enabling full-body tracking, closed-loop feedback and interactive applications. > Read More
Access to raw data and full control of your motion pipeline
Work with raw IMU data, fused orientation, kinematics or skeletal models — without black-box processing. This makes QSense suitable for both research and product development.
Built for real-world environments
Unlike many IMUs optimized for lab conditions, QSense is engineered to perform reliably in uncontrolled, dynamic environments such as sports fields, clinics, industrial settings and outdoor scenarios.
From prototype to OEM product, on one platform
The same sensor and software stack scales from pilot studies to embedded OEM products, reducing redevelopment effort when moving from R&D to production.
Motion sensing where performance really matters
Many motion sensors are designed for consumer devices or controlled lab conditions. QSense is built for real use.
It performs reliably in:
- clinical and rehabilitation settings
- sports fields and training environments
- industrial workplaces
- tactical and outdoor scenarios
When conditions are unpredictable and movement quality matters, QSense delivers data you can trust.
Designed for high-fidelity motion intelligence
At the heart of the QSense sensor is a high-quality 9-DOF IMU combining accelerometer, gyroscope and magnetometer data. Through advanced fusion and calibration strategies, QSense provides stable, low-drift orientation and motion outputs suitable for both real-time feedback and research-grade analysis.
Whether you work with raw inertial data, fused kinematics or skeletal representations, QSense gives you full control over your motion pipeline.
Built for real-time use
QSense is engineered for low-latency, real-time applications.
This enables:
- interactive coaching and feedback
- rehabilitation guidance and exergaming
- XR avatar control and training simulations
- closed-loop control and human–machine interaction
Measure. Analyze. Act. In real time.
Part of an open, scalable platform
QSense is not a standalone gadget. It is a core component of the QSense Motion Platform – a complete ecosystem that includes:
- wearable IMU sensors
- wireless communication and synchronization
- open SDKs and APIs
- visualization and recording tools
- OEM and scale-up support
You can start with a single sensor and scale to full-body or multi-device setups without changing platforms.
From prototype to production – with one technology stack.
Where QSense is used
The QSense IMU Motion Sensor is used as a foundation for applications such as:
Rehabilitation & Health
Gait analysis, movement quality assessment, return-to-function decisions
Sports & Performance
Technique analysis, workload monitoring, injury risk reduction
Industry & Ergonomics
Task analysis, ergonomic risk assessment, workplace design
Defense & Tactical Training
Readiness assessment, movement analysis under load, training safety
Interactive Training & XR
Avatar control, simulation, human–machine interaction
If your application depends on accurate human motion data, QSense provides the sensor foundation to build on.
