● TRACKING Technology
Motion tracking, simplified.
By combining ultrasonic, optical and inertial inputs, our 6DoF tracking precisely measures the position and orientation of devices in 3D space, accurate to the millimeter, drift-free, and viable in the real world.
01 How it works
Three signals, one spatial truth
Integration
2 MICS
4 INTEGRATED MICS ULTRASOUND ONLY · NOTHING NEEDED IN THE HOST
Camera + 2 microphones — optical anchoring stacks on the acoustic core for the tightest spatial frame.
The emitter rides the tracked object — a ring, a pen, a tag are examples; so is a training firearm or a surgical instrument. Reception is just microphones, so the host stays unmodified, headset or no headset. Explore the spatial tools →
Acoustic
Ultrasonic ranging
Ultrasonic transducers (pMUT or MEMS) measure time-of-flight between emitter and receiver for precise distance, with no camera needed and reduced line-of-sight requirements.
Optical
Visual anchoring
Where a camera is available, optical cues anchor the frame and enhance accuracy even further, fusing seamlessly with the ultrasonic core.
Inertial
IMU motion
Inertial sensors capture fast, fine motion between ranging updates, delivering smooth, low-latency 6DoF at high rates.
Minimum requirements: one camera + one microphone, or three microphones if no camera is available. No modifications to the host headset.
02 The form is irrelevant
Any shape. One tiny module.
Above is how we track. This is what gets tracked: anything. The tracking module is small enough to ride a pencil, a ring, a tag, an instrument — watch it move between bodies.

03 Precision benchmark
0.00mm mean position error.
Benchmarked against commodity XR tracking. Lower is better, Sensoryx leads the field while needing no dedicated tracking hardware in the headset. Switch metrics, or cover every camera and watch the acoustic core hold.
SensoryxACOUSTIC ONLY 1.83mm◂ best

Lower is better. Dynamic conditions vs a freshly calibrated 6-camera OptiTrack ground truth; Sensoryx running on an unmodified Qualcomm XR2 reference design. NO-CAMERA MODE = cameras covered, acoustic ranging alone still tracks.
04 Capabilities
