The aim of the MaMeK (Projektionssysteme für die Maschine-Mensch-Kommunikation / Projection systems for machine-human communication) joint project is to research and develop two technological approaches for displays, as well as their analysis and evaluation for integration into a Car2Human communication concept. The aim is to develop holographic direct view displays and highly efficient ground projection systems which enable a dynamic display of information.

In addition to scientific and technological development, it is important to determine user requirements at an early stage of research and to consistently link these to the technological work.

At the end of the project, the systems developed will be integrated into a demonstration vehicle and connected with the corresponding sensors of a semi-autonomous or highly autonomous vehicle.

HOLOEYE tasks in the project

The ground projection system is based on the principle of holographic pattern projection. Compared with direct imaging, holographic pattern projection has the advantage of a much higher light efficiency.

In this project, HOLOEYE develops the core component of the holographic projection: a LCOS SLM. This SLM is characterized by:

  • Full-HD resolution (1920×1080 pixel)
  • Small pixel size (4.5µm) to allow projecting a wide pattern
  • High light efficiency
  • High-speed (Refresh Rate > 60Hz) for a real-time display of changing information
  • A high degree of compactness of the SLM and the driving electronics, for supporting the integration in low-space automotive environment

Aside from the SLM hardware, HOLOEYE also develops a software solution for driving 12 SLM from a single PC and performs a first series of tests for a future automotive qualification.
