The User Experience of Journeys in the Realm of Augmented Reality Television

Abstract

Augmented Reality Television (ARTV) can take many forms, from AR content displayed outside the TV frame to video-projected TV screens to social TV watching in VR to immersive holograms in the living room. While the user experience (UX) of individual forms of ARTV has been documented before, "journeys" as transitions between such forms have not. In this work, we examine the UX of watching TV when switching between various levels of augmentation. Our fndings from an experiment with fourteen participants reveal an UX characterized by high perceived usability, captivation, and involvement with a low to medium workload and a moderate feeling of dissociation from the physical world. We interpret our results in the context of Garrett's established fve-plane model of UX-strategy, scope, structure, skeleton, and surface-and propose a sixth plane, "switch, " which separates conceptually the design of user journeys in ARTV from the specifcs of the other UX planes.

A Review of Milgram and Kishino’s Reality-Virtuality Continuum and a Mathematical Formalization for Combining Multiple Reality-Virtuality Continua

“…They also proposed an algorithm for edge and shadow extraction, and used it in a new system, "Anime Glasses", that converts natural scenes into anime style in real time. Finally, Pamparȃu and Vatavu [9] proposed a definition for a journey in ARTV continuum [8] as a transition between two points of this continuum, that is a 2D space where the vertically axis represents Milgram's RVC and the horizontally axis is also Milgram's RVC, but used in the context of Television.…”

“…An example of XR transition protocol is the one employed by Pamparȃu and Vatavu [9] for transitioning in different points of ARTV Continuum, that consisted in a keyboard connected to HoloLens HMD device via bluetooth and 1, 2, 3 or 4 keys that participants in their experiment used to transit between different level of augmentation, i.e., different points in ARTV Continuum. Since a combination of three RVC axes could easily be modeled as a cube, we want to address the combination of more than three RV Continua in a different way.…”

“…Recently, Pamparȃ and Vatavu introduced the concept of a journey in ARTV Continuum [8] as a transition between two points of this continuum, that is a 2D space where the vertically axis represents Milgram's RVC and the horizontally axis is also Milgram's RVC, but used in the context of Television. Hence, they invited participants of their experiment to view and explore the same video in four different augmentation levels; see [9] for details, and section III for details regarding previous work on transitional interfaces.…”
