“…For example, participants self-reported greater presence in VR environments designed for exposure therapy when administered relevant olfactory stimuli; in another case, the scent of basil enhanced presence for participants immersed in a 360 video showing street vendors in a public square (Munyan et al, 2016;Narciso et al, 2020). Evidence from a virtual environment exploring the four seasons suggested that the addition of an olfactory component increased user presence (Ranasinghe et al, 2018). In other work, an unpleasant odor paired with a VRbased kitchen scene increased presence while a pleasant scent did not (Baus and Bouchard, 2017); a follow-up study with slightly different visual VR stimuli found that both pleasant and unpleasant odors increased the sense of reality but that neither had any significant effect on presence (Baus et al, 2019).…”

Virtual reality (VR)'s effectiveness as a medium for training, education, research, and entertainment, is based in large part on the fact that users can be deeply immersed and feel present within virtual environments. Olfaction has received less attention regarding its ability to add realism to VR environments. It is important to investigate under which circumstances olfactory stimuli are likely to add to user experience and help achieve the goals of VR applications. This study examined the role of scent in a VR-based buffet restaurant environment. French fry scented oil was administered while participants made a plate of food in the VR Buffet. Participants were asked afterwards to report on smells they perceived. Only 18% of participants perceived the olfactory stimulus, 78% of whom correctly identified it. Perceiving the olfactory stimulus was associated with higher levels of presence in the VR Buffet. Correctly identifying the olfactory stimulus was associated with heightened presence and increased likelihood of choosing french fries from the VR Buffet. These results demonstrate the potential for variability in scent perception and related user experience in VR. Additionally, this study highlights a need for future research into factors that underlie and moderate olfactory perception in VR environments.

“…Gallace et al (2012) observed that increasing the number of senses stimulated in a VR stimulator enhanced a user's sense of presence, their enjoyment, and memory of the experience. As a matter of fact, some studies have already included olfactory stimuli in virtual environments (e.g., Baus & Bouchard, 2017;Micaroni et al, 2019;Ranasinghe et al, 2018). Their effects have been studied for such specific uses as military training (Vlahos, 2006), firefighter training, and medical diagnosis (Spencer, 2006) or posttraumatic stress disorder treatment (Aiken & Berry, 2015).…”

Smells Influence Perceived Pleasantness but Not Memorization of a Visual Virtual Environment

et al. 2021

The present study aimed to investigate whether the perception of still scenes in a virtual environment in congruent versus incongruent condition can be influenced by odors. Ninety healthy participants were divided into three groups, including two experimental virtual reality (VR) environments: a rose garden, an orange basket, and a control condition. In each VR condition, participants were exposed to a rose odor, an orange odor, or no odor, resulting in congruent, incongruent, and control conditions. Participants were asked to describe (a) the content of the VR scene and rate its overall pleasantness and (b) the smell and to rate its intensity and pleasantness. For each condition, participants were tested twice. During the second test, participants provided ratings and descriptions of the content of the VR scenes without being exposed to odors or VR environments. Virtual scenarios tended to be remembered as more pleasant when presented with congruent odors. Furthermore, participants used more descriptors in congruent scenarios than in incongruent scenarios. Eventually, rose odor appeared to be remembered as more pleasant when presented within congruent scenarios. These findings show that olfactory stimuli in congruent versus incongruent conditions can possibly modulate the perception of the pleasantness of visual scenes but not the memorization.

“…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.…”

“…Therefore, users have to wear many devices to receive multiple types of stimuli on various body locations. Multipurpose feedback devices are an emerging direction to address these challenges by triggering different stimuli, thus yielding higher immersion (Murakami et al 2017;Choi et al 2018;Dementyev et al 2016;Ranasinghe et al 2017Ranasinghe et al , 2018Harley et al 2018).…”

HapticSnakes: multi-haptic feedback wearable robots for immersive virtual reality

et al. 2019

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.
