Abstract: Development of a VR Speech Trainers with heartbeat monitoring and
eye contact measurement as feedback to improve public speaking [DE]
Andrej Langlitz, Development of a VR Speech Trainers with heartbeat monitoring and
eye contact measurement as feedback to improve public speaking, Hochschule Düsseldorf, Bachelor thesis, 25.08.2023.
The present work deals with the conception and implementation of a Virtual Reality
(VR) Speech Trainer, which has been extended to include heart rate monitoring and
eye contact measurement. Using the Unity development environment, the aim of this
work is to investigate the extent to which these additional features represent
added value compared to conventional VR Speech Trainers. This work outlines the
complete development process, with particular emphasis on the implementation of
the innovative features. These focus on aspects that are of great importance when
delivering a public speech, such as the ability to maintain eye contact and
awareness of one’s stress level, derived by monitoring the heart rate.
Furthermore, the work provides an in-depth understanding of the theoretical
foundations and technical aspects to consider when developing applications in the
field of virtual reality. The analysis and interpretation of the achieved results
are carried out in a scientific context, providing meaningful insights into
the efficiency and effectiveness of the developed VR Speech Trainer. In conclusion,
this work presents a functioning VR-Speech-Trainer, highlighting the potential of
Virtual Reality in education and training. This contribution to research in the
field of VR opens up new perspectives for future investigations and underscores
the relevance of this topic for modern education and personal development.
