Natural Motion Intelligence

We help understand how people naturally move
— in daily life, not in the lab.

Our technology

Cameras on the shoes.
The whole body in 3D.

Motion capture usually watches people from the outside — cameras on tripods, markers on the skin, a lab around it all. We turned it around: two small cameras on the shoelaces look up at the body, wherever it goes.

01Real world 02What the shoes see 03Full-body 3D
01
Looks up at the body

A wide-angle camera on each shoe sees the legs, the upper body and the ground ahead — step after step, indoors or out.

02
Feels every step

A built-in motion sensor (IMU) picks up each foot contact and the rhythm of every stride.

03
AI rebuilds the motion

Our models combine both into full-body 3D motion and the path travelled — no cameras in the room, no markers, no calibration. Patented in the EU and US.

See it move

Any movement.
Measured accurately.

From running drills to the walking patterns clinicians care about — every joint and every stride reconstructed in 3D, from the shoes alone.

From sport to clinical gait patterns

Circumduction walking

A stroke gait pattern: the leg swings out in an arc instead of straight forward.

Path & foot contact

Where the body goes, and when each foot touches the ground.

Crouch gait

Bent-knee walking, often seen in children with cerebral palsy.

Dragging foot

Subtle foot contacts that camera-only systems struggle to see.

Our markets

One technology.
Four markets.

Today, our sensors bring lab-grade motion capture to wherever people actually move.

Tomorrow, everything they capture teaches AI how humans move — so it can help people recover from injury, train smarter, stay independent as they age, and share the world safely with robots.
