Twenty-four participants will be recruited from the Hong Kong Polytechnic University. Participants will be assigned to the "Digital Strolling" or control group. Participants in the "Digital Strolling" group will receive an arm swing virtual walking intervention, which consists of 20 minutes of virtual walking for 10 days and is conducted at home. Qualitative interviews with the "Digital Strolling" group will be conducted to understand their acceptability, usability, perceived strengths, and limitations of the intervention.
