Stage 3
Impromptu Speaking
Participants took part in an impromptu speaking activity. The purpose is to warm up their vocal chords. This stage was conducted using a set of computer generated images. The participants spoke as the pictures appeared in front of them. Each image was shown for 30 seconds before changing to the next picture. This activity was completed after 6 pictures.
- Participants completed a self-evaluation survey at this stage.
- VR Participants were asked to read the feedback generated by the application.
- Non-VR Participants receive their feedback from a human assessor.

Stage 4
Online Presentation on Zoom
Participants were given 10 minutes to prepare for a 5-minute zoom presentation on the topic of “Living in a Covid-19 Pandemic”. A sample script was provided to the participant to modify and adapt for their own usage. They were encouraged to generate ideas from their personal experiences instead of reading off the given script.
- Upon receiving feedback from the previous stage (refer to stage 3), participants considered the feedback given to improve their oral presentation.
- The participants were tasked to present to a simulated zoom setting with virtual audience.
- The participants completed a self-evaluation at this stage.
- VR Participants were asked to read the feedback generated by the application. Non-VR participants were given feedback by a human assessor using a set of assessment criteria.
Stage 5
Presentation in TedX Style Setting (For VR Participants)
Upon receiving feedback from the previous stage (refer to stage 4), participants were required to consider the feedback given to improve on their oral presentation in stage 5. Participants were given another 10 minutes to improve and edit their 5-minute speech to prepare for a TedX Style presentation on the topic of “Living in a Covid-19 Pandemic”.
- This stage was conducted using the VR-headset, participants were tasked to present in a simulated TedX Styled Theatre setting with a larger group of virtual audience.
- Participants were taught how to use a VR-headset and how to orientate themselves with it (e.g. how to turn your head, speak, what to select etc.).
- Participants started presenting whenever they were ready and stopped when they have ended their speech
- While waiting for their results to be generated, they were required to fill up a self-evaluation survey.
- VR Participants were asked to read the system generated feedback.
Stage 5
Presentation in TedX Style Setting (For Non-VR Participants)
Upon receiving feedback from the previous stage(refer to stage 4), participants were required to consider the feedback given to improve their oral presentation. At stage 5, participants were given10 minutes to edit their 5-minute speech and then prepare for a TedX Styled presentation on the topic of “Living in a Covid-19 Pandemic”.
- This stage was conducted on the research website, where participants were tasked to present in a stimulated TedX Styled Theatre setting with a larger group of virtual audience. Participants start presenting whenever they are ready and stop when they have ended their speech.
- While waiting for their results to be generated, they were required to fill up a self-evaluation survey.
- Non-VR Participants received their feedback at the end of this stage from the human assessor in the lab.
Stage 6
Final Oral Presentation
At stage 6, participants were required to consider the feedback given to improve their oral presentation. Participants were given another 10 minutes to improve and edit their 5-minute speech to prepare for the final oral presentation on the topic of “Living in a Covid-19 Pandemic”.
- Participants were given an option to make use of a PowerPoint slide to make referral notes for the presentation
- After 10 minutes, the participants presented to the assessors.
- The assessors graded the participants according to a standardised rubrics. No feedback was given for the final round.
- After the presentation, the participants were required to answer a set of post-activity survey.
Studies on the use of VR for enhancing training effectiveness are rare, and the study on its effects remain to be a vast area for further exploration and analysis.
