Performance of Augmented Reality Remote Rendering via Mobile Network
In this paper, a remote rendering system for an AR app based on Unity is presented. The system was implemented for an edge server, which is located within the network of the mobile network operator.

Addressing Deaf or Hard-of-Hearing People in Avatar-Based Mixed Reality Collaboration Systems
We propose an easy to integrate Automatic Speech Recognition and textual visualization extension for an avatar-based MR remote collaboration system that visualizes speech via spatial floating speech bubbles. In a small pilot study, we achieved word accuracy of our extension of 97% by measuring the widely used word error rate.

The influence of different audio representations on linear visually induced self-motion
We investigate the influence of four different audio representations on visually induced self-motion (vection). Our study followed the hypothesis, that the feeling of visually induced vection can be increased by audio sources while lowering negative feelings such as visually induced motion sickness.

Perceptual Comparison of Four Upscaling Algorithms for Low-Resolution Rendering for Head-mounted VR Displays
When rendering images in real-time, shading pixels is a comparatively expensive
operation. Especially for head-mounted displays, where separate images are rendered for
each eye and high frame rates need to be achieved. Upscaling algorithms are one possibility
of reducing the pixel shading costs. Four basic upscaling algorithms are implemented in a
VR rendering system, with a subsequent user study on subjective image quality. We find
that users preferred methods with a better contrast preservation. -
Using MQTT for Platform Independent RemoteMixed Reality Collaboration
In this paper, we present a Mixed Reality telepresence system that allows the connection of multiple AR or VR devices to create a shared virtual environment by using the simple MQTT networking protocol. It follows a subscribe-publish pattern for reliable and easy platform independent integration. Therefore, it is possible to realize different clients that handle communication and allow remote collaboration. To allow embodied natural human interaction, the system maps the human interaction channels, gestures, gaze and speech, to an abstract stylized avatar by using an upper body inverse kinematic approach. This setup allows spatially separated persons to interact with each other via an avatar-mediated communication.
