The work aims to analyze the effectiveness of interactive media-based outdoor advertising on the brand information, and provide direction on the dissemination of information in the interactive media-based outdoor advertising. On the basis of interactive media, outdoor interactive advertising and brand cognition, a model was constructed from three elements of physics, perception and media to study the effect factor of information transmission, which could effectively affect the brand awareness, and discuss the effective path of brand involvement and outdoor interactive advertising. The effect mechanism of outdoor advertising interactive media on brand communication and the main strategies to effectively improve brand awareness were clarified. The interactive media-based outdoor advertising is the performance of social interaction, which is centered on the perceptual factor.
