AR in TV: Design and Evaluation of Mid-Air Gestures for Moderators to Control Augmented Reality Applications in TV

Abstract

Recent developments in augmented reality for TV productions encouraged broadcasters to enhance interaction with virtual content for moderators. However, traditional interaction methods are considered distracting and not intuitive. To overcome these issues, we performed a gesture elicitation study with a follow-up evaluation. For this, we considered TV moderators as primary users of the gestures as well as viewers as recipients. The elicited gesture set consists of five gestures for two types of camera shots (long shot and close shot). Findings of the evaluation study indicate that the derived set of gestures requires low physical and concentration effort from moderators. Also, both moderators and viewers found them appropriate to be used in TV with respect to understandability, distraction, likeability, and appropriateness. Using these gestures would allow moderators to control AR content in TV and tell stories in a modern and more expressive way.
