Holodeck 4.0 utilizes the following system components:
Precision positioning and tracking technology
Positioning is based on a combination of different technologies developed by Fraunhofer IIS. Moving about freely within a large area of virtual worlds requires highly-precise positioning technology. With the RedFIR® technology, Fraunhofer IIS offers a proven and robust positioning and tracking technology which is set up at the L.I.N.K. Test and Application Center. The existing system, with its positioning components, was optimized especially for use with Holodeck 4.0. Apart from RedFIR®, other positioning technologies can be easily integrated.
The miniaturized and extremely robust RedFIR® transmitters, which can be easily mounted on or integrated in a head-mounted display, are both weather and shock proof. The batteries operate for 3 to 4 hours and are recharged over-the-air. The system supports up to 100 transmitters, allowing multiple users to interact with another and simultaneously discover the different virtual worlds.
Users can immerse themselves in the boundless virtual worlds of Holodeck 4.0 with smartphone-based head-mounted display (HMD) units. The precise positioning data is transmitted via WiFi. The orientation data is derived from the gyroscope, magnetometer and accelerometer technology in the smartphone. Once the sensor and positioning data has been merged, the virtual world can be directly generated in the smartphone. The portable design ensures comfortable and wireless movement in the real world.
Utilization of the Unity 3D gaming engine allows the platform-independent development of virtual worlds. That means 3D worlds can also be experienced on other end-user devices, thus making interaction possible across a wide range of media. The most popular 3D formats can be easily integrated into our chosen gaming engine. Depending on the application, this gives developers the freedom to create a variety of virtual worlds.
