The set of physical and sensitive phenomena that interacts with the urban morphology acts on the resulting perception from the users of a place. Its study and representation provides elements beyond the aesthetics aspects that can allow a better understanding of the space and future urban projects. We aim to analyze the effects of three different wind representations in terms of perception and sense of presence in virtual reality (VR). We focus on the following conditions: (R) reference scene with the audiovisual representation of the mechanical effects of the wind on the elements of the context, (V) reference scene plus the visualization of the wind flow, present (among others) in the architecture field, (T) reference scene plus tactile restitution of wind and eventually (V+T) assembling all previous conditions. For the experiment, we present to the participants (R), then (V) followed by (T), and finish with (V+T). 37 participants evaluated 12 different stop points (divided into four routes in the same simulated street), where they had to determine the perceived wind force and direction concerning the four different conditions (each one corresponding to one route). At the end of each route, participants evaluated their sense of presence in the VR scene. Our analysis showed significant effects of tactile restitution over the visual effects used in the study, both for understanding wind properties and for increasing the sense of presence in the VR scene. In terms of wind direction, (T) reduced the estimation error by 27% compared to (V). Concerning wind force, the reduction was 9.8%. As far as presence was concerned, (T) increased the sense of presence by 12.2% compared to (V).

“…Varied feedback in VR Researchers have investigated a variety of feedback types, including haptic feedback, that aimed at attaining deeper immersion and presence in VR. Different works utilized fans to generate airflow, such as a fixed fan on a head-mounted display (Ranasinghe et al 2018), multiple fans around user's head (Rietzler et al 2017) or wrist (Shim et al 2018). Strasnick et al (2017) presented a prototype that includes six small wristmounted brushes, where attributes like rotational speed, duration and direction can be utilized to convey different kinds of information.…”

“…The mounted fan is able to generate an airflow in different body regions, which is essential for increasing immersion (Ranasinghe et al 2017(Ranasinghe et al , 2018Rietzler et al 2017). Unlike previous systems which focused on the face, HapticSnakes can deliver such feedback to other locations.…”

Haptic feedback plays a large role in enhancing immersion and presence in VR. However, previous research and commercial products have limitations in terms of variety and locations of delivered feedbacks. To address these challenges, we present HapticSnakes, which are snake-like waist-worn robots that can deliver multiple types of feedback in various body locations, including taps-, gestures-, airflow-, brushing- and gripper-based feedbacks. We developed two robots, one is lightweight and suitable for taps and gestures, while the other is capable of multiple types of feedback. We presented a design space based on our implementations and conducted two evaluations. Since taps are versatile, easy to deliver and largely unexplored, our first evaluation focused on distinguishability of tap strengths and locations on the front and back torso. Participants had highest accuracy in distinguishing feedback on the uppermost regions and had superior overall accuracy in distinguishing feedback strengths over locations. Our second user study investigated HapticSnakes’ ability to deliver multiple feedback types within VR experiences, as well as users’ impressions of wearing our robots and receiving novel feedback in VR. The results indicate that participants had distinct preferences for feedbacks and were in favor of using our robots throughout. Based on the results of our evaluations, we extract design considerations and discuss research challenges and opportunities for developing multi-haptic feedback robots.

“…As many people experience the sensation of wind on their entire body every day, we can easily immerse ourselves in VR presentations with wind displays. The latter can improve immersion by faithfully reproducing the motion of objects in VR environments [5], self-motions [6,12], and climates [11]. The reproduction of wind blowing from various directions is often crucial to simulate realistic wind.…”

“…Therefore, wind display devices tend to be complicated and large under this implementation. VaiR [12] addresses this problem by implementing two rotatable bow-shaped frames that enable continuous change in wind directions. This approach could reduce the required number of wind sources, but requires actuators and mechanisms to move the device.…”

Wind displays, which simulate the sensation of wind, have been known to enhance the immersion of virtual reality content. However, certain wind displays require an excessive number of wind sources to simulate wind from various directions. To realize wind displays with fewer wind sources, a method to manipulate the perceived directions of wind by audio-haptic cross-modal effects was proposed in our previous study. As the visuo-haptic cross-modal effect on perceived wind directions has not yet been quantitatively investigated, this study focuses on the effect of visual stimuli on the perception of wind direction. We present virtual images of flowing particles and three-dimensional sounds of wind as information to indicate wind directions and induce crossmodal effects in users. The user study has demonstrated that adding visual stimuli effectively improved the result corresponding to certain virtual wind directions. Our results suggest that perceived wind directions can be manipulated by both visuo-haptic and audio-haptic cross-modal effects.
