While ordinary touchscreen-based interfaces on urban explorer applications draw much of a user's attention onto the screen, visual and audio-haptic augmented reality interfaces have emerged as the two main streams for enabling direct focus on the surroundings. However, neither interface alone satisfies users in the highly dynamic urban environment. This research investigates how the two complementary augmentation can coexist on one system and how people adapt to the situation by selecting the more suitable interface. A prototype was deployed in a field experiment in which participants explored points of interest in an urban environment with both interfaces. The engagement with the surroundings was compared with a touchscreen-based application. Most participants spontaneously switched between the two interfaces, which manifests the value of the availability of both interfaces on one system. The results point at the situated advantages of either interface and reveal the users' preferences when both interfaces are available.
