Head-Mounted Virtual reality (VR) systems provide full-immersive experiences to users and completely isolate them from the outside world, placing them in unsafe situations. Existing research proposed different alert-based solutions to address this. Our work builds on these studies on notification systems for VR environments from a different perspective. We focus on: (i) exploring alert systems to notify VR users about non-immersed bystanders' in socially related, non-critical interaction contexts; (ii) understanding how best to provide awareness of non-immersed bystanders while maintaining presence and immersion within the Virtual Environment(VE). To this end, we developed single and combined alert cues -leveraging proxemics, perception channels, and push/pull approaches and evaluated those via two user studies. Our findings indicate a strong preference towards maintaining immersion and combining audio and visual cues, push and pull notification techniques that evolve dynamically based on proximity.

“…Our grasping patterns are useful for designers creating VR environments that require direct interaction with objects, specially for training (i.e. VR training environments in construction and manufacturing [5], surgical training techniques [54]) where the user experience could be vulnerable [17]. In these scenarios, the shape of the objects needs to be considered, with objects being designed to specifically encourage this user selection of precision grasps and thus facilitating a more precise and finer manipulation.…”

“…To relieve the visual channel, an alternative approach is to use vibrotactile directional feedback, as vibrotactile sensation displayed on the side of the user's body that is facing a particular target or object 5 . Vibrotactile displays can be worn on various body parts such as head [5][6][7][8] , neck 9 , torso 10 , abdomen 11,12 and limbs 13 to provide explicit feedback and support tasks like locomotion, orientation, and obstacle detection 11 .…”

Despite the common use of visual aids for spatial guidance, the extensive use of visual elements can lead to interface overcrowding and visual overload. In contrast, tactile navigation presents a vision-free alternative in assisting way-finding tasks. However, previous studies kept directional cues constantly active in experiments, overlooking potential differences in user interaction behavior caused by variations in interpretation speed and localization accuracy between visual, tactile, and combined spatial guidance. Additionally, these studies typically simplified navigation tasks, focusing on following cues without the multitasking demands of large-scale virtual environments. This paper aims to fill the gap by investigating the effects of visual, vibrotactile (equidistant and localized magnification), and combined (visual + equidistant and visual + localized magnification) spatial guidance modalities on task performance, user behavior and tendency in large-scale virtual environments.By building an immersive virtual scene that enables continuous tracking of participants' performance and interaction behaviors, results indicated no significant disparities in task completion times and way-finding strategies across modalities. However, tactile modalities were activated more frequently but for a shorter duration compared to visual and combined modalities. Moreover, when both visual and tactile directional cues were presented, users tended to rely on visual cues.
