Here are a few images from a project completed for a famous French luxury brand in Japan.
The objective was to promote a gold bracelet in a totally new way, engage a thinking like “how is it on me?” and leave guests with an amazing souvenir that they want to share online.

But wait! How does it work? How could it find people wrist? Let’s break the magic.
In stealth mode, LM3LABS’ 3DFeel sensor tracks guest’s skeletton. Even distant guests were in the radar, precisely tracked and numbered, one by one. As the guest come closer to the camera, they discover themselves wearing the jewel at their wrist, on the screen. 3DFeel identifies the right arm from the left one, it calculates the distance to the hand so that the bracelet is correctly positioned, it understands the position of the elbow and shoulder (3D rotation also known as quaternion matrix) so that the bracelet matches the arm position. The final process is to “extrude” the arm flesh (or cloth) in the video stream to fit the 3D bracelet into it. All this frame by frame.

Surprise, smile, picture. 1, 2, 3, Flash!
A picture is taken and appears right on the side screen with a unique number.
Guests could get their picture by e-mail while we were feeding our database with their e-mail address, name and picture.

The operation has been a huge success with thousands of smiling pictures and a large buzz on fashion blogs in Japan.

The technology in action:

a few minutes of happy people…
