Abstract: Innovative techniques and apparatuses to control metaverse presentation are disclosed. The proposed techniques and apparatuses allow prevention of overindulgence to metaverse presentation based on user biometrics (e.g., oxygen saturation, heart rate, body temperature, blood pressure, etc.). If the biometrics indicate that the user's health is compromised due to the metaverse presentation, the metaverse presentation (visual, audio, haptic outputs) may be altered to reduce the user's overindulgence.
