Abstract. We introduce MockAR, a prototyping application for designing user interfaces for mobile handheld Augmented Reality, to be used by non-program‐ ming media designers. It has been successfully employed in the project SPIRIT, which develops location-based AR storytelling for outdoor historical sites, including complex interaction and navigation features based on mobile phone sensors and markerless image recognition.

Introduction: AR User Interface Design Prototyping Tool
Interaction with Augmented Reality (AR) and the need for appropriate user inter‐ faces have been topics of research for several decades [4, 6, 8] . However, available design frameworks mainly target expert developers and -users such as programmers. There are no standard or commonplace user interaction metaphors, as it has widely been a niche topic. For a long time, AR has also been associated with special devices such as head-mounted displays and extra hardware for tracking or tangible interfaces [6]. Only recently, new kinds of mobile apps for off-the-shelf phones and tablets become widespread. They include AR in form of a visual overlay of digital informa‐ tion on real objects or landmarks on a camera image. For entertainment and educa‐ tion purposes, such AR applications are to be conceived in a consumer market. This development produces an increasing need for non-programmers, such as media designers, to tackle AR elements as new media to be included in the conception and design of communication with their target groups. Like in other areas of media conception, interface design and graphics, designers need easy to use prototyping tools. In the research project SPIRIT, a location-based mobile AR application has been developed that includes AR video overlay on specific spots of a cultural heritage site. Visitors shall experience entertaining on-the-spot storytelling, together with scavengerhunt-like spatial interactions and information seeking, based on mobile device sensors. Storytellers and UI designers have been involved in the design of UI features integrated with the interactive story’s concept. Figure 1 shows an early functional prototype, that had to be redesigned for more user guidance.

As a side result in the SPIRIT research project, we developed the AR UI prototyping tool MockAR for the project’s non
