Tiled Stereoscopic 3D Display Wall - Concept, Applications and Evaluation

Abstract

The Tiled Stereoscopic 3D Display Wall (TS3DW) is a monitor system consisting of six consumer 3D TVs. Two monitors reside on a mobile display mount. One standard configuration is to use them in a 135-degree angle to each other, having one mobile mount in the center, and one at each side. In this way, the system can be transported to multiple locations across a campus as well as used in different application scenarios. This system was already used for a number of research projects and presentations. In this work, we present the concept, applications and evaluation of the implemented system. First, we will discuss the hardware setup, the passive circular polarization technology provided by the LG 3D TVs and its limitations. Then, two application cases making use of Stereoscopic 3D visualization will be discussed and compared to previous work: • Visualization and Analysis of Bird Trajectories, • Visualization and Analysis of Meteorite Data. Finally, we discuss a comprehensive evaluation of the system and its stereoscopic capabilities featuring 16 participants with different body heights. Three major questions were evaluated: • Is TS3DW an appropriate environment for group presentations? • If so, which aspects have to be taken into account during its configuration? • Does TS3DW show potential to be used in the context of static and/or dynamic bird visualization?

Visual analytics of sensor movement data for cheetah behaviour analysis

“…In addition, it also allows us to freely design and extend visualisations, data representations, and interactions. As Cesium provides web-based interactive visualisations (DC5), and features a VR-mode, it allows us to provide one implementation that can be used in the field in a normal browser setup, in mobile VR, and in immersive environments (Dwyer et al 2018;Sommer et al 2019). Furthermore, it provides a server-based solution that allows the user to connect from a client machine.…”

TEAMwISE: synchronised immersive environments for exploration and analysis of animal behaviour

“…Cesium is a JavaScript library for geographical globe and map visualisations that allows us to create map-based visualisations that include animated trajectory representations, but also to freely design and extend visualisations, data representations, and interactions. As Cesium provides web-based interactive visualisations and features a VR-mode; it allows us to provide one implementation that can be used in diverse set-ups and environments such as in the field in a normal browser set-up, in mobile VR, and in immersive environments (Dwyer et al 2018;Sommer et al 2019). Furthermore, using Node.js (Nodejs 2019), TEAMwISE provides a web server-based solution that allows the user to connect either from the local host or from a remote client machine.…”

“…We present TEAMwISE (Tool for Exploration and Analysis of Movement data within Immersive Synchronised Environments)-an extensible framework for the exploration of movement data across devices in an immersive fashion. TEAMwISE supports collaborative data analysis, either collocated in an immersive or in a semi-immersive environment, such as a tiled 2D/3D display wall (TDW, (Sommer et al 2019)), or via shared mobile virtual environments. It combines a visualisation of trajectories in the geographic context with movement analysis and supports the synchronised interactive visualisation of multiple views.…”

Immersive Design Engineering

“…In this way, the monitor setup can easily be transported to different places and configured in different ways. Figure 8 shows the "Tiled Stereoscopic 3D Display Wall" showing multiple perspectives based on bird flight data [66]. It supports stereoscopic visualization using S3D TVs.…”
