Abstract:

Giving presentations can be challenging for many students due to a variety of reasons. Identifying and overcoming the obstacles and problems associated with presenting can help individuals to become more confident and better presenters. Becoming a skilled and good presenter takes practice and effort. Some common mental obstacles that make presenting difficult for some people include fear of public speaking, lack of confidence, and difficulty in organizing thoughts. In this research we designed a tool that enables educators and students to train and practice in an immersive Virtual reality (VR). This simulation allows the presenter to interact with the panel sitting in front of them, get feedback and rehearse the presentation as many times as needed. The simulation also includes questions that the virtual panel asks, with difficulty levels selected by the user. There are responses that can be triggered by a conductor of the simulation which gives real time feedback to the presenter. Responses can be triggered by the conductor of the simulation, providing real-time feedback to the presenter. However, to evaluate the effectiveness of the tool, we recognize the need for biometric responses to measure the presenter's anxiety and stress levels during the simulation. To address this issue, we have utilized a brain-computer interface (BCI) to measure the stress levels of each presenter during each session. By analyzing the results after several training sessions, we can demonstrate the effectiveness of the tool in helping presenters overcome their mental obstacles and improve their presentation skills.
