“…Populating large environments with virtual content is a challenge, however, without effective navigation techniques, users will not be able to explore content quickly and easily in these environments. Many techniques have been proposed to improve navigation, such as jumping [4,39], teleportation [5,22], virtual body resizing [1,18], and flying [26], among others.…”

“…There are manifold reasons for visualization in VR, such as a better understanding of spatial relationships [64], or the increased presence and an improved cognitive map due to natural locomotion (i.e., walking) [38,61,62]. Nevertheless, these advantages cannot prevent us from possibly getting lost in the amount of visualized data, and, thus, we continue to need robust and intuitive highlighting techniques.…”

Fig. 1. Left: Our experiments in VR with homogeneous and heterogeneous distractors, as we investigate the preattentiveness and robustness of Deadeye in such scenarios. Right: We demonstrate and evaluate volume rendering in VR as a possible real-world application scenario for our technique. Abstract-Visualizations rely on highlighting to attract and guide our attention. To make an object of interest stand out independently from a number of distractors, the underlying visual cue, e.g., color, has to be preattentive. In our prior work, we introduced Deadeye as an instantly recognizable highlighting technique that works by rendering the target object for one eye only. In contrast to prior approaches, Deadeye excels by not modifying any visual properties of the target. However, in the case of 2D visualizations, the method requires an additional setup to allow dichoptic presentation, which is a considerable drawback. As a follow-up to requests from the community, this paper explores Deadeye as a highlighting technique for 3D visualizations, because such stereoscopic scenarios support dichoptic presentation out of the box. Deadeye suppresses binocular disparities for the target object, so we cannot assume the applicability of our technique as a given fact. With this motivation, the paper presents quantitative evaluations of Deadeye in VR, including configurations with multiple heterogeneous distractors as an important robustness challenge. After confirming the preserved preattentiveness (all average accuracies above 90 %) under such real-world conditions, we explore VR volume rendering as an example application scenario for Deadeye. We depict a possible workflow for integrating our technique, conduct an exploratory survey to demonstrate benefits and limitations, and finally provide related design implications.

“…We picked that setting for two particular reasons. First, if virtual and real rooms match in size and shape, locomotion can be achieved by natural walking, which has a positive impact on presence [50,26] and removes the need for additional, artificial navigation techniques, such as teleportation. Hence, players can focus more on the actual animal experience and are less distracted by accompanying functionalities.…”

Figure 1. We explore the potential of nonhuman avatars in VR games. The evaluation of our three escape room games for different animal types reveals that players enjoy the control over additional body parts, as such morphologies allow novel, refreshing interactions and enable superhuman abilities. ABSTRACTVirtual reality setups are particularly suited to create a tight bond between players and their avatars up to a degree where we start perceiving the virtual representation as our own body. We hypothesize that such an illusion of virtual body ownership (IVBO) has a particularly high, yet overlooked potential for nonhumanoid avatars. To validate our claim, we use the example of three very different creatures-a scorpion, a rhino, and a bird-to explore possible avatar controls and game mechanics based on specific animal abilities. A quantitative evaluation underpins the high game enjoyment arising from embodying such nonhuman morphologies, including additional body parts and obtaining respective superhuman skills, which allows us to derive a set of novel design implications. Furthermore, the experiment reveals a correlation between IVBO and game enjoyment, which is a further indication that nonhumanoid
