AR Enhanced Pictorial Warnings on Smoking Cessation

Mobile Phone Based Personalized and Interactive Augmented Reality (AR) Pictures on Enhancing Brief Advice Model for Smoking Cessation: a Pilot Randomized Controlled Trial

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

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.

• Hong Kong adults aged 18 or above;
• Smoke at least 1 cigarette daily in the past 30 days;
• Own a smartphone and familiar with instant messaging apps;
