abstract = {Virtual reality (VR) glasses enable to be present in an environment while the own physical body is located in another place. Recent mobile VR glasses enable users to be present in any environment they want at any time and physical place. Still, mobile VR glasses are rarely used. One explanation is that it is not considered socially acceptable to immerse in another environment in certain situations. We conducted an online experiment that investigates the social acceptance of VR glasses in six different contexts. Our results confirm that social acceptability depends on the situation. In the bed, in the metro, or in a train, mobile VR glasses seem to be acceptable. However, while being surrounded by other people where a social interaction between people is expected, such as in a living room or a public cafe, the acceptance of mobile VR glasses is significantly reduced. If one or two persons wear glasses seems to have a negligible effect. We conclude that social acceptability of VR glasses depends on the situation and is lower when the user is supposed to interact with surrounding people.},

abstract = {Entering text is one of the most common tasks when interacting with computing systems. Virtual Reality (VR) presents a challenge as neither the user's hands nor the physical input devices are directly visible. Hence, conventional desktop peripherals are very slow, imprecise, and cumbersome. We developed a apparatus that tracks the user's hands, and a physical keyboard, and visualize them in VR. In a text input study with 32 participants, we investigated the achievable text entry speed and the effect of hand representations and transparency on typing performance, workload, and presence. With our apparatus, experienced typists benefited from seeing their hands, and reach almost outside-VR performance. Inexperienced typists profited from semi-transparent hands, which enabled them to type just 5.6 WPM slower than with a regular desktop setup. We conclude that optimizing the visualization of hands in VR is important, especially for inexperienced typists, to enable a high typing performance.},

abstract = {Pointing at remote objects to direct others' attention is a fundamental human ability. Previous work explored methods for remote pointing to select targets. Absolute pointing techniques that cast a ray from the user to a target are affected by humans' limited pointing accuracy. Recent work suggests that accuracy can be improved by compensating systematic offsets between targets a user aims at and rays cast from the user to the target. In this paper, we investigate mid-air pointing in the real world and virtual reality. Through a pointing study, we model the offsets to improve pointing accuracy and show that being in a virtual environment affects how users point at targets. In the second study, we validate the developed model and analyze the effect of compensating systematic offsets. We show that the provided model can significantly improve pointing accuracy when no cursor is provided. We further show that a cursor improves pointing accuracy but also increases the selection time.

abstract = {Hand tracking and haptics are gaining more importance as key technologies of virtual reality (VR) systems. For designing such systems, it is fundamental to understand how the appearance of the virtual hands influences user experience and how the human brain integrates vision and haptics. However, it is currently unknown whether multi-sensory integration of visual and haptic feedback can be influenced by the appearance of virtual hands in VR. We performed a user study in VR to gain insight into the effect of hand appearance on how the brain combines visual and haptic signals using a cue-conflict paradigm. In this paper, we show that the detection of surface irregularities (bumps and holes) sensed by eyes and hands is affected by the rendering of avatar hands. However, sensitivity changes do not correlate with the degree of perceived limb ownership. Qualitative feedback provides insights into potentially distracting cues in visual-haptic integration.},

abstract = {Avatars in virtual reality (VR) increase the immersion and provide an interface between the user's physical body and the virtual world. Thus, avatars enable referential gestures, which are essential for targeting, selection, locomotion, and collaboration in VR. However, players of immersive games can have another virtual appearance deviating from human-likeness and previous work suggests that avatars can have an effect on the accuracy of referential gestures in VR. One of the most important referential gestures is mid-air pointing. It has been shown that mid-air pointing is affected by systematic errors, which can be compensated using different methods. Thus, it is unknown if the avatar must be considered in corrections of the systematic error. In this paper, we investigate the effect of the avatar on pointing accuracy. We show that the systematic error in pointing is significantly affected by the virtual appearance but does not correlate with the degree to which the appearance deviates from the perceived human-likeness. Moreover, we confirm that people only rely on their fingertip and not on their forearm or index finger orientation. We present compensation models and contribute with design implications to increase the accuracy of pointing in VR.},
