Enabling technologies for tracking XR users

In MAX-R, UHasselt is integrating enabling technologies for tracking XR users around large complex environments and for adaptive network streaming of XR experiences.

Large-area tracking with perfect alignment of the virtual with the real world will allow users to explore XR environments and have an experience of physicality and interaction with their surroundings. The scaled-up XR experience will provide a sense of freedom as it perfectly coincides with the physical world.

Adaptive network streaming of XR experiences allows for the composing assets of an XR scene to be dynamically transmitted to the user’s consumption device, where the network delivery is tailored to prevailing contextual factors like network throughput but also the pose of the user in the XR space. By streaming instead of downloading the XR scene, the consumer can be immersed in the XR experience much sooner. Also, only the needed parts of the XR scene will be delivered over the network, while irrelevant ones (e.g., spatial areas of the XR world that are not explored by the user) will not be transmitted; this saves network bandwidth and thus has a positive ecological impact.
