AR Enhanced Pictorial Warnings on Smoking Cessation

Not Applicable

Completed

• Conditions: Smoking Cessation

• Registration Number: NCT04830072
• Lead Sponsor: The University of Hong Kong

Brief Summary

This pilot randomized controlled trail aims to test the effects of AR enhanced pictorial effects in harms of smoking and benefit of smoking cessation.

Detailed Description

Conventional health warnings on smoking harms mostly include pictures showing smoking consequences such as lung diseases, peripheral vascular diseases, aging, skin lesions, and benefit of quitting such as improved cardiopulmonary functions, skin conditions and risk of diseases, etc. The effects of the information are limited by the generic messages, unattractive images, and lack of interaction. This proposal aims to enhance the "Warn" and "Advice" materials using mobile phone-based augmented reality (AR) technologies to provide personalized, interactive, and attractive images to encourage smokers to quit smoking.
