Asymmetric Interface: User Interface of Asymmetric Virtual Reality for New Presence and Experience

Abstract

This study proposes an asymmetric interface that can provide head-mounted display (HMD) and non-HMD users with improved presence and an experience consistent with the user’s environment in an asymmetric virtual reality. For the proposed asymmetric interface, a controller-based hand interface is designed for portability, easy and convenient use, and high immersion. Subsequently, a three-step decision-making structure that supports accurate and efficient decision-making is defined based on the asymmetric experience structure of each user (HMD and non-HMD). Based on this process, an optimal interface that distinguishes between HMD (direct interaction) and non-HMD users (multi-viewpoint interaction) is implemented. With the objective of surveying and analyzing each user’s experience along with the presence provided by the proposed interface, an asymmetric virtual reality application is developed directly, and an experiment is conducted with the participants. Finally, it is statistically analyzed and verified that the use of the proposed asymmetric interface can provide optimal presence and user-optimized experience to both HMD and non-HMD users.

A Best-Fit Framework and Systematic Review of Asymmetric Gameplay in Multiplayer Virtual Reality Games

“…These game designs can leverage the benefits of multiplayer game experiences (e.g., supporting social connectedness; Woods, 2009;Vella et al, 2019) without requiring additional HMDs. Examples include giving bystanders insight into the virtual environments (VEs) inhabited by the HMD player (e.g., via a monitor displaying their camera perspective; Jeong et al, 2020), or an active role in the game (e.g., giving them essential information that the HMD player requires, thus enforcing communication; Liszio and Masuch, 2016;Smilovitch and Lachman, 2019).…”

Low-Asymmetry Interface for Multiuser VR Experiences with Both HMD and Non-HMD Users

“…Simultaneously, visual and perspective information is also an important factor affecting realism. In previous studies [ 5 , 46 ], it was shown that using both first- and third-person viewpoints can significantly improve the realism and presence experienced by non-HMD users. In our system, we ensured that in addition to a first-person viewpoint, non-HMD users were also provided with a third-person viewpoint, enabling them to grasp their own position in the VE and the distance from HMD users.…”

“…Setups with various levels of asymmetry differently influence the capability of users to complete tasks in a VE, thereby affecting presence and immersion. The authors of [ 5 ] proposed an asymmetric user interface to enhance the interaction between non-HMD and HMD users and to provide non-HMD users with first- and third-person perspectives to enhance user immersion. ShareVR’s research [ 1 ] explored the effectiveness of co-located asymmetric interaction between HMD and non-HMD users and used a tracked display and floor projection to visualize the virtual space for the non-HMD users, thereby increasing their immersion and enjoyment.…”

“…In these studies, because both types of users could change the perspective and influence the environment, the related setups correspond to the low-asymmetry realm. However, because the non-HMD visual display is generally a fixed desktop PC [ 5 ] or a wired tracked display [ 1 ] instead of a portable wireless device, the studies have limitations arising from the difficulties experienced by non-HMD users in engaging with the VE in any location. In addition, realistic locomotion contributes substantially to the immersion and presence in VR [ 6 ].…”

Sanal Gerçeklik Ortamlarında Bulunma Hissi

“…Benzer olarak, Schulz, Alexandrovsky, Putze, Malaka, ve Schöning 2019 | 2020; 18 (4); Beşerî Bilimler -İktisadi İdari Bilimler Ortak Sayısı olumlu olarak etkilendiği görülmüştür (Schulz ve diğerleri, 2019). Son dönemlerde gerçekleştirilen çalışmalardan bir diğerinde Jeong, Kim, Kim, Lee, ve Kim (2020) sanal gerçeklik ortamındaki el kontrollerinin arayüz tasarımı için asimetrik bir yaklaşım izlemişlerdir. Geliştirdikleri yeni ara yüz tasarımı ile hem başa takılan görüntüleyiciler ile gerçekleştirilen hem de sadece el kontrolcüleri ile gerçekleştirilen sanal gerçeklik uygulamalarında yaşanan bulunma hissi düzeyinin arttığı tespit edilmiştir.…”
