FAURECIA Canatu door demonstrator

YEAR CREATED: 2017, Client: Faurecia Innenraum Systeme GmbH

In this demonstration model of a driver's door, the mechanical controls for the window regulators, the control of ventilation and heating as well as the massage functions of the seat were replaced by purely capacitive touch sensors.

The sensors consist of 3D-deformable, transparent touch films from Canatu and can therefore be installed above the 2.8" -TFT display for the menu display or above the RGB LEDs for the icon background lighting.

Since the door model has no connection to real windows, a seat or heating/ventilation, an additional 2.4" TFT display was integrated that shows the respective effects of user interactions using graphics and Displays animations.
