About this study

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.
