1. The target audience of unique outdoor advertising is pedestrians on the move. Pedestrians receive product information through visible advertising images, so in designing outdoor advertisements, it is necessary to consider three factors comprehensively: distance, angle of view, and environment. On vast plazas and sidewalks along roads, audiences can conveniently see objects that are 5 meters above head level from a distance of over 10 meters. Therefore, the first step in design is to determine the position and size of the advertisement based on these three factors: distance, angle of view, and environment. Common outdoor advertisements are usually rectangular or square, but when we design them, we should adapt to the specific environment, making the shape of the outdoor advertisement coordinate with the background to produce visual beauty. There's no need to force uniformity in shape; it can be diversified, and the size should be determined according to the actual space size and environmental conditions. For example, road signs in Italy are not very large, which aligns well with its ancient streets, creating a harmonious appearance. Outdoor advertising should focus on creating good viewing effects because the success of an advertisement is based on the effectiveness of its viewing contact.
