It is proved that emotion does affect one’s working performance and many researchers pointed out that Heart Rate Variability (HRV) can be used to detect people’s emotion. A new machine learning model will be trained in this project to detect users' emotion with HRV wristbands during VR corporate training. A new mobile application will be developed together with the wristband to provide instantaneous feedback during VR training. Human behaviour analysis reports can also be generated through big data collection where optimized solutions will be provided to further improve users’ experience and working performance.
