A comparison of both approaches is described in Table 1. Examples of both black and white markers and image-based markers are shown in Fig. Any image can be used to trigger AR content but a high level of contrast and detail in the image, as well as more processing power, are required. Alternatively, regular images provide a “markerless” interaction, which is a more ubiquitous and user friendly approach. This unique pattern allows the AR software to select the correct AR content that is linked to the marker. They are typically square shapes with unique black and white patterns inside.
Black and white markers are the most recognizable, reliable, and widely used type of augmented reality.
