Evaluating and Updating a Design Space for Augmented Reality Television.

As Augmented Reality Television (ARTV) transitions out of the feasibility phase, it is crucial to understand the impact of design decisions on the viewers’ ARTV experiences. In a previous study, six ARTV design dimensions were identified by relying on insights from existing prototypes. However, the set of possible dimensions is likely to be broader. Building on top of previous work, we create an ARTV design space and present it in a textual cheat sheet. We subsequently evaluate the cheat sheet in a between-subject study (n = 10), with participants with wide-ranging expertise. We identified six new dimensions (genre, broadcast mode, audience demographics, cartoonish vs. photoreal representation, modality, and privacy), and a new aspect (360°) for the display dimension. In light of our observations, we provide an updated ARTV design space and observe that asking participants to write ARTV scenarios can be an effective method for harvesting novel design dimensions.
