Transitional Interfaces in Mixed and Cross-Reality: A new frontier?

Abstract

Figure 1: Transitional Interfaces (TI) enable users to move between different locations within the reality-virtuality (RV) continuum. They enable users to choose the technology that best supports the task at hand and fulfils their information need.

A Study on Collaborative Visual Data Analysis in Augmented Reality with Asymmetric Display Types

“…The three notebooks and the three AR devices act as clients and establish connections with the server. Our primary focus was to ensure a responsive network communication [34] to support a seamless and consistent data-sharing experience among all three users. To optimise network efficiency, we utilised Unity's Netcode Library, which supports server remote procedure calls (RPCs) and client RPCs.…”

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

“…For instance, George et al [29] defined the user possibility to explore transitions between Milgram's RVC states without taking the headset off as seamless transition concept (SeaT), proposing a design space for further investigating of seamless, bi-directional transitions, that consists of four dimensions, such as (1) motivation for transition (social interaction and collaboration, physical integrity & orientation, awareness, and interaction with physical & virtual objects), ( 2) availability (user-triggered, system-triggered and continuous), ( 3) modality (visual, audio or haptic), and (4) the act of transitioning itself. By exploring to the same concept, Jetter et al [7] introduced Transitional Interfaces (TI) term, that enable users to move between different locations within the RVC; TIs allows users to choose the technology that best supports the task at hand and fulfills their information need. Finally, last year Wang et al [30] proposed a design space for single-user cross reality applications that consists of four dimensions: (1) transition and concurrent usage (a user transits from one point on the RVC to another, a user moves a visualization from one point on the RVC to another, a user interacts with multiple systems that belong to different points on the RVC concurrently), (2) output device, (3) input device (interacting with multiple systems along the RVC, interacting with one system along the RVC), and ( 4) interaction (transiting to another reality, moving a visualization across realities, selecting object across realities, and manipulating object across realities).…”

“…Next, we formalize the combination of more than two RVC axes, each of them consisting in a unique, different mixed reality experience. We draw inspiration from Milgram and Kishino definition of Augmented Reality, and Jetter's [7] concept of transitional interfaces.…”

“…For example, in 1999, Milgram and Colquhoun [4] formalized the transitions in RVC; also, 1 https://scholar.google.com/scholar?hl=ro&as sdt=0%2C5&q=A+TAX ONOMY+OF+MIXED+REALITY+VISUAL+DISPLAYS&btnG= Grasset et al [5], [3] addressed this topic in both practical and theoretical ways. A few years later, Roo et al [6] introduced a taxonomy for transitioning RVC, while Jetteret al [7] proposed his own definition for transitional interfaces. 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.…”

A Survey on Cross‐Virtuality Analytics

“…Within this space, cross‐virtuality analytics (XVA) is a novel field of research, concerned with systems for data visualization and analysis that seamlessly integrate different visual metaphors and devices along the entire RVC to support multiple users with transitional and collaborative interfaces. Two recent workshops in this field [SKE*20, JSG*21] emphasize the importance and relevance of the topic. According to Riegler et al .…”
