This study investigates the impact of a mindfulness-based intervention using virtual reality (VR) and artificial intelligence (AI) coaching on stress reduction. Participants will engage in VR-based observation mindfulness activities guided by an AI coach. The study aims to evaluate the effectiveness of this intervention compared to a standard relaxation process by measuring self-reported stress levels, physiological biomarkers (e.g., heart rate), and participant satisfaction. The research could inform the development of future digital mental health interventions.

This study employs a randomized controlled design to assess the effectiveness of a VR-based mindfulness intervention for stress reduction. Participants are randomly assigned to either the experimental group, which undergoes VR-based observation mindfulness activities guided by an AI coach, or the control group, which experiences standard relaxation exercises. Pre-intervention data, including self-reported stress levels (measured via PSS-10, DASS-21, and STAI) and baseline heart rate, are collected. Following the intervention, participants complete post-intervention measurements to evaluate changes in stress levels, physiological responses, and satisfaction with the VR program.

The experimental group participates in mindfulness activities designed to enhance attention to detail and present-moment awareness through object observation within the VR environment. The AI coach facilitates the session by prompting reflective and observational questions, fostering deeper engagement. The control group undergoes relaxation exercises with no active mindfulness engagement. All procedures are conducted in a controlled laboratory setting, ensuring consistency and minimizing external variables.

The study collects objective (heart rate and heart rate variability) and subjective (self-reported stress and satisfaction) data to evaluate the intervention's efficacy. The findings aim to provide insights into the feasibility and benefits of integrating VR and AI technologies in stress reduction interventions. The results will also contribute to the development of more engaging and accessible digital mindfulness practices for diverse populations.

Inclusion Criteria:

• Adults aged 18 years and older.

Exclusion Criteria:

• Those with visual or hearing impairments that prevent interaction with VR content.
