The current study sought to objectively evaluate cybersickness by utilizing Electrogastrogram (EGG) physiological data in relation to three different navigation axes: Translational movement along the longitudinal and lateral axes, and rotation along the vertical Yaw axis. EGG was employed as it has been clinically identified as a valuable tool for capturing dysfunction in the stomach. This resulted in a 2x2x2 factorial design. Results from both subjective and objective measurements (N=26, F=10) indicate that rotation along the Yaw axis is the primary factor influencing cybersickness. Additionally, it was found that individuals who are not susceptible to cybersickness do not exhibit any dominant factors. In summary, through the analysis of EGG data, several key physi- ological indicators of individual susceptibility to cybersickness were identified. The findings suggest that there is a positive correlation between the mean dominant frequency and the tachygastria ratio with individual susceptibility, while the normalgastria and normal- tachy ratio were found to be negatively correlated with individual susceptibility
