Maximilian Schäfer presents paper at GI-Workshop

Tuesday 25 August 2020

One of our first students in the Visual Computing & Games Technology Master has just successfully handed in a paper: In the course "Scientific Writing" he prepared the results of his practical project as a scientific publication which he submitted to the VR/AR workshop of the Gesellschaft für Informatik (GI).

Maximilian Schäfer developed a three-dimensional display consisiting of several semi-transparent projection screens. He compared this with a stereoscopic 3D display in a study with 20 test persons. In various application scenarios from the games sector, he identified undesirable side effects such as nausea. The results indicate that the self-developed display caused fewer side effects with the same or better spatial perception. 

He will present the paper at the workshop on 24/25.9. in Trier. Due to the corona pandemic, the VR/AR workshop will be held completely online. Interested parties can still register until 10 September.

Abstract

In this paper we propose and evaluate a custom-build projection-based multi-layer 2.5D display, consisting of three layers of images, and compare performance to a stereoscopic 3D display. Stereoscopic vision can increase the involvement and enhance game experience, however may induce possible side effects, e.g. motion sickness and simulator sickness. To overcome the disadvantage of multiple discrete depths, in our system perspective rendering and head-tracking is used.


A study was performed to evaluate this display with 20 participants playing custom-designed games.The results indicated that the multi-layer display caused fewer side effects than the stereoscopic display and provided good usability. The participants also stated a better or equal spatial perception, while the cognitive load stayed the same.
