# ECG VR-TSST v3.0



The Entertainment Computing Group VR-TSST (ECG VR-TSST) is a tool for experimental induction of acute mental stress in the laboratory. It is a VR adaptation of the original Trier Social Stress Test protocol developed by Kirschbaum, Pirke, and Hellhammer (1993). The ECG VR-TSST works with HTC Vive and Oculus Rift. 



The ECG VR-TSST has been successfully used to generate high stress levels in several studies (Liszio, Graf & Masuch, 2018; Liszio & Masuch, 2019). 



The application is available in the current version 2.3 in German and English and has a modular design. Different tasks for the subjects can be combined. Furthermore, the number of virtual testers can be varied. The ECG VR-TSST also has a logging module.



Further information about the scope and the empirical evaluation of the tool can currently be described here: https://doi.org/10.17185/duepublico/74774.



The ECG VR-TSST under is the [GNU General Public License v3.0](https://www.gnu.org/licenses/gpl-3.0.html). 



# Background

The original project traces back to the work of Dr. Stefan Liszio. All functions of the tool in version 1 and version 2 as well as the different development steps and and especially the results of the empirical evaluation of the effectiveness in stress induction are summarized here.
