Abstract:
Inside-out optical 2D tracking of tangible objects on a surface oftentimes uses a high-resolution pattern printed on the surface. While De-Bruijn-torus patterns offer maximum information density, their orientation must be known to decode them. Determining the orientation is challenging for patterns with very fine details; traditional algorithms, such as Hough Lines, do not work reliably. We show that a convolutional neural network can reliably determine the orientation of quasi-random bitmaps with 6 × 6 pixels per block within 36 × 36 pixel images taken by a mouse sensor. Mean error rate is below 2°. Furthermore, our model outperformed Hough Lines in a test with arbitrarily rotated low-resolution rectangles. This implies that CNN-based rotation-detection might also be applicable for more general use cases.

Abstract:
The work introduces Project Hubble, Unity's internal multi-user XR collaboration tool. Hubble provides a delightful interface to navigate and manipulate freeform and guided experiences. Tools and technology are provided on top for voice chat, avatars, annotations, and sharing.

Abstract:
Glasshouse is a dance for virtual reality experience in three parts. A near future biosphere where plant and insect life thrive in an ecosystem of integrated biotechnology. Maintained by intuitive glasshouse keepers who farm water and light, biotech agriculture and drone insects work in synergy with ancient flora and heirloom edibles.

Abstract:
We present Immersive-Labeler, an environment for the annotation of large-scale 3D point cloud scenes of urban environments. Our concept is based on the full immersion of the user in a VR-based environment that represents the 3D point cloud scene while offering adapted visual aids and intuitive interaction and navigation modalities. Through a user-centric design, we aim to improve the annotation experience and thus reduce its costs. For the preliminary evaluation of our environment, we conduct a user study (N=20) to quantify the effect of higher levels of immersion in combination with the visual aids we implemented on the annotation process. Our findings reveal that higher levels of immersion combined with object-based visual aids lead to a faster and more engaging annotation process.
