FAURECIA "Collections" POI kiosk

Year created: 2021, electronic concept, realisation and programming, Client: Faurecia Innenraum Systeme GmbH

The POI kiosk presents 14 surface materials for vehicle interiors that can be illuminated or heated. The 14 square material samples are surrounded by an all-round illuminated edge, 2 modules are heated and the remaining 12 modules can be illuminated with light effects.

The kiosk can be operated interactively using gesture control and built-in pressure sensors. In addition, any mobile device can open a specially developed web app in the browser via the integrated WALN interface, which can be used to call up detailed information on the materials of the modules and control the lighting of the selected module.

A total of over 10,000 individually controllable RGB LEDs (WS2812) have been installed - the edge light is generated by side LED strips with a total of 636 LEDs, and all 12 transilluminable modules are each mounted on a 28x28 LED matrix, so that complex lighting patterns and animations can be displayed.

Internally, the system is controlled via a combination of a Windows PC (running a web server for the WebApp, reading the Leap Motion sensor for gesture control and UART connection to the Arduino Mega), an Arduino Mega (for general sequence control and operating logic, evaluation of the pressure sensors and control of the edge lighting) and 3x Teensy 4.0 microcontrollers (for controlling 4 LED matrix modules per Teensy).

Functions and interactivity

  • Programming the light animations for the halo light (edge lighting) and the LED matrix backlighting (radial wipe, radial fill)
  • Programming a Unity Windows .exe in C# for gesture recognition using the Leap Motion Sensor
  • Design and programming of the WepApp (HTML, Css, Javascript and PHP)
  • Heating control and temperature monitoring of the heatable material samples
