Smart Object Segmentation to Enhance the Creation of Interactive Environments
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 to them in a further step. It takes a lot of effort to do this manually as single objects have to be extracted and post-processed. Thus, our research aim is the real-world, cross-domain, automatic, semantic segmentation without the estimation of specific object classes.

Point Cloud Segmentation: Solving a Perceptual Grouping Task with Deep Reinforcement Learning
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.

Point Cloud Segmentation with Deep Reinforcement Learning
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 extinguishing of a fire. It is necessary to segment the point cloud scans to create interactions in the VR

3D Scanner for Mixed Reality
Being able to teleport people and objects or even entire rooms is a long-cherished dream and has been shown in many science fiction movies. Thanks to innovative technologies, it is now possible to scan rooms and people as well as to digitize and “teleport” them by sending the scans to a remote location.

Photogrammetry
Our goal is to create realistic 3D images of objects or rooms. For this purpose, we use the laser scanner Faro Focus S70, which can capture anything visible in a sphere with a radius of up to 70 meters. Whenever we scan a room, we also move along the walls and take overlapping photographs. Overall, depending on the size of the room or object, we collect between 600 and 1500 pictures to ensure that we obtain enough material in a single scanning process.

Smarthome AR
In this research project, we try to find out what kind of added value AR (augmented reality) may offer for a smart-home application. To answer this question, we have created a 3D model of an existing sitting area with a sofa and we work with smart-home sensors that enable us to control various aspects.

The Effects on Presence of Personalized and Generic Avatar Faces
With today’s technology it has become possible to generate and control personalized as well as authentic avatar faces in 3D for social Virtual Reality (VR) applications, as Lombardi et al. [LSSS18] have recently shown. Creating a personalized avatar with facial expressions is expensive in terms of time, computational power and hardware.
