The creation of interactive virtual reality (VR) applications from 3D scanned content usually includes a lot of manual and repetitive work. Our research aim is to develop agents that recognize objects to enhance the creation of interactive VR applications. We trained partition agents in our superpoint growing environment that we extended with an ex...

The objective of our research is to enhance the creation of interactive environments such as in VR applications. An interactive environment can be produced from a point cloud that is acquired by a 3D scanning process of a certain scenery. The segmentation is needed to extract objects in that point cloud to, e.g., apply certain physical properties t...

We propose a method to segment a real world point cloud as perceptual grouping task (PGT) by a deep reinforcement learning (DRL) agent. A point cloud is divided into groups of points, named superpoints, for the PGT. These superpoints should be grouped to objects by a deep neural network policy that is optimised by a DRL algorithm. During the PGT, a...

The segmentation of point clouds is conducted with the help of deep reinforcement learning (DRL) in this contribution. We want to create interactive virtual reality (VR) environments from point cloud scans as fast as possible. These VR environments are used for secure and immersive trainings of serious real life applications such as the extinguishi...

The perception of the movement of the own fingers is important in VR. Also the sense of touch of the hands provide crucial information about an object that is touched. This is especially noticeable when climbing in VR. While prototyping a VR climbing application, we developed the finger tracking glove g 1. Glove g 1 enables the perception of the fi...

Zusammenfassung Die Nutzererfahrung einer VR-Applikation, die eine Outdoor Virtual Environment (OVE) enthält, hängt von Kriterien wie der Präsenz während der Interaktion ab. Interagiert man mit einer OVE in einem geschlossenen Raum, können Wetterparameter nur virtuell simuliert werden. Die Immersion des Systems wird jedoch erhöht, wenn der Nutzer d...
Conference Paper
Scary climbing situations can appear when climbing on big walls. Some stones may be slippery due to humidity or smoothness and distances between belaying bolts can be large whereby a deep fall is risked. In such situations, the stress level increases, climbing performance decreases and an ascent might even be aborted. Furthermore, hazardous acciden...

Using a trampoline as a natural 3D user interface with a head-mounted display for virtual reality entertainment is a novel and challenging task. High latencies between interaction and feedback or inaccurate tracking of the user’s movement can lead to simulator sickness. In the scope of this project we identified the most appropriate solutions for t...
Conference Paper
Virtuell interaktiv unterwegs - im Rahmen eines Bachelorprojekts wurde im Sommer 2013 eine 3D-Simulation eines virtuellen Drachenflugs entwickelt. Dabei wurde ein echter Drachenflieger mit einem Gerüst so umgebaut, dass eine realitätsnahe Bewegungskontrolle in einer virtuellen 3D-Welt möglich wurde. Durch verschiedene Möglichkeiten multimodalen Nut...
