Daily Exposure to Virtual Nature Reduces Symptoms of Anxiety in College Students
Figure 3. 360-degree videos shown in the virtual nature intervention (Courtesy of INVIROVR). Exposure to natural environments offers an array of mental health benefits. Virtual reality provides simulated experiences of being in nature when outdoor access is limited. Previous studies on virtual nature have focused mainly on single “doses” of virtual nature. The effects of repeated exposure remain poorly understood. Motivated by this gap, we studied the influence of a daily virtual nature intervention on symptoms of anxiety, depression, and an underlying cause of poor mental health: rumination. Forty college students (58% non-Hispanic White, median age = 19) were recruited from two U.S. universities and randomly assigned to the intervention or control group. Over several weeks, anxious arousal (panic) and anxious apprehension (worry) decreased with virtual nature exposure. Participants identifying as women, past VR users, experienced with the outdoors, and engaged with the beauty in nature benefited particularly strongly from virtual nature. Virtual nature did not help symptoms of anhedonic depression or rumination. Further research is necessary to distinguish when and for whom virtual nature interventions impact mental health outcomes.
Read moreDifferent Types of Virtual Natural Environments Enhance Subjective Vitality Through Restorativeness
Figure 1. Graphical representation of the experimental procedure. The body of evidence supporting the psychological benefits of exposure to virtual nature, such as increased mood and decreased stress, is rapidly growing. However, few studies have explored the potential of virtual nature to boost subjective vitality, defined as a positive feeling of aliveness and energy. In this contribution, we investigate the role of virtual nature in enhancing subjective vitality through restorativeness. In particular, we expand the existing literature by considering different types of natural environments (i.e., a national park, a lacustrine environment, and an arctic environment vs. an urban environment). We designed a randomized between-subject design with a sample of 113 university students (Mage = 21.99, SD = 1.82). Participants were exposed to four 360-degree panoramic photos with a virtual reality (VR) head-mounted display. We collected measures of the variables of interest immediately before and after exposure, and a series of control variables (i.e., sociodemographics, individual differences and personal conditions, previous VR experience, frequency of contact with nature, and variables related to participants’ experience during VR). We performed a mediation analysis with a multicategorical independent variable (i.e., the experimental condition). Results confirmed our hypotheses, with three significant indirect effects of virtual nature exposure on subjective vitality through restorativeness, one for each natural environment as compared to the urban environment. The wide range of practical implications for different types of psychological interventions as well as future research directions are discussed.
Read moreEmotion Regulation and Virtual Nature: Cognitive Reappraisal as an Individual-Level Moderator for Impacts on Subjective Vitality
Figure 1. Graphical representation of the simple slope analysis. CR cognitive reappraisal. People who make habitual use of an emotion regulation strategy such as cognitive reappraisal may be more sensitive to the emotion cues coming from a surrounding natural environment and, thus, get more benefits from virtual nature exposure such as enhanced subjective vitality. However, no previous study investigated the moderating role of cognitive reappraisal in the relationship between exposure to different types of natural environments (a national park, a lacustrine environment, and an arctic environment vs. an urban environment) and subjective vitality. We designed a between-subject design (four conditions, one per type of environment) with a sample of 187 university students (Mage = 21.17, SD = 2.55). Participants were exposed to four 360° panoramic photos of the environment for one minute each with a virtual reality head-mounted display. The results of a multicategorical moderation analysis attested that there were two significant interactions, respectively between lacustrine and arctic environments and cognitive reappraisal. More specifically, for participants with low levels of habitual use of cognitive reappraisal, the effects of virtual nature (vs. urban) exposure on subjective vitality were not significant, while for participants with high levels, the effects were significant and positive. Findings show how the potential of virtual nature may be boosted with training aimed at increasing the general use of cognitive reappraisal, supports enhancing the applications of virtual nature, and demonstrates the need to take individual differences into account when determining the benefits of these applications.
Read moreStress Recovery from Virtual Exposure to a Brown (Desert) Environment Versus a Green Environment
Fig. 1. Experimental procedure. Note: Mean arterial pressure, pulse, and cortisol measures were collected 6 times during the experiment (i.e. Stage T0∼T5). Serum samples were collected at T0 and T5. TSST: Trier Social Stressor Test. The beneficial association between nature contact and human health is often explained with psycho-evolutionary frameworks such as stress reduction theory and the savanna hypothesis. However, evidence is limited on how natural environments that are not green affect stress. One example is the desert, which does not offer affordances for nourishment or safety in an evolutionary sense. In this study, we determine the effect of a virtual reality (VR) exposure to a desert vs. green environment among 95 healthy adult male residents of El Paso, Texas. The procedure consisted of an acute stressor followed by random assignment to a 10 min VR experience (desert, green space, or office [control condition]) and a 40 min resting period. Participants in the desert condition showed significant reductions in salivary cortisol compared to participants in the office. Participants in the desert condition showed decreases in mean arterial pressure compared to participants in the control condition. Collectively, these findings suggest that factors beyond those proposed by psycho-evolutionary frameworks such as lived experiences and familiarity with landscapes may play a role in the health benefits of nature exposure.
Read moreWhen Screen Time Isn’t Screen Time: Tensions and Needs Between Tweens and Their Parents During Nature-Based Exploration
Figure 1: Screens of the NatureCollection app 1: Onboarding “What are your interests?” 2: Homepage 3: My Collections 4: Classification 5: Challenges We investigated the experiences of 15 parents and their tween children (ages 8-12, n=23) during nature explorations using the NatureCollections app, a mobile application that connects children with nature. Drawing on parent interviews and in-app audio recordings from a 2-week deployment study, we found that tweens’ experiences with the NatureCollections app were influenced by tensions surrounding how parents and tweens negotiate technology use more broadly. Despite these tensions, the app succeeded in engaging tweens in outdoor nature explorations, and parents valued the shared family experiences around nature. Parents desired the app to support family bonding and inform them about how their tween used the app. This work shows how applications intended to support enriching youth experiences are experienced in the context of screen time tensions between parents and tween during a transitional period of child development. We offer recommendations for designing digital experiences to support family needs and reduce screen time tensions.
Read more“Otter this World”: Can a Mobile Application Promote Children’s Connectedness to Nature?
Can a mobile application encourage children to spend more time outdoors and promote their connectedness to nature? In this paper, we present results from a three-week experimental deployment study of NatureCollections, a mobile application that allows users to build, curate, and share nature photo collections. Twenty-eight children (aged 9-12) and their parents participated in the study; 15 used the NatureCollections app, and 13 used a basic Photo app. We found that the NatureCollections app significantly increased the time children spent outdoors compared to the Photo app. Children in both groups said they felt happy and excited about spending time in nature. However, children in the NatureCollections group reported that time spent outside with the app increased their curiosity about the types of species and plants they saw and photographed. Children in the NatureCollections group also engaged in nature-based conversations with their parents, and even sought to look up information online about the plants and animals they observed. In contrast, children in the basic Photo app group did not display this level of curiosity about what they saw in nature, and the photos they took were driven largely by the aesthetic qualities of nature elements. Our results suggest that NatureCollections promotes and supports children’s connectedness to nature.
Read moreSparking Interest: A Design Framework for Mobile Technologies to Promote Children’s Interest in Nature
Can a mobile app engage children in explorations of the natural world and promote their interest in nature? Drawing on theory related to interest development and research on mobile learning technologies, we derived a set of four design principles to support the development of children’s personal interest in nature. We co-designed with 7 children ages 7–12 a set of interest-centered design strategies to implement each of the following principles: (1) personal relevance, (2) focused attention, (3) social interactions, and (4) opportunities for continued engagement. We applied these strategies to design NatureCollections, a mobile application that allows children to build, curate, and share nature photo collections. We conducted an in-situ case study with 18 children ages 7–11 years who used the NatureCollections app to take pictures of their natural surroundings. Qualitative indicators suggest NatureCollections succeeded in directing children’s attention to and promoting close observation of the natural elements in their surroundings, and prompted playful, nature-related conversations with peers and parents.
Read moreTechnological Nature and Human Well-Being
In terms of physical and psychological well-being, does it matter that on a worldwide level we are replacing interactions with actual nature with technological nature—technologies that mediate, simulate, and augment the natural word? Research from three forms of technological nature are reviewed: a technological nature window, robot pets, and a telegarden. Results suggest that while interacting with technological nature is better than nothing, it is not as good as interacting with real nature. A concern with accepting technological nature is that it can shift the baseline downward for what counts as optimal well-being, as people across generations lose experiences with healthy baselines, a process referred to as environmental generational amnesia. One result is that we ask too little of the idea of urban sustainability, confusing biological living with human flourishing.

Figure 1: Screens of the NatureCollection app 1: Onboarding “What are your interests?” 2: Homepage 3: My Collections 4: Classification 5: Challenges As part of our research, we are studying the potential for interactive technologies to create opportunities for children to connect with nature. We developed a beta version of a mobile application, NatureCollections, that was co-designed with KidsTeam UW, that aims to engage young children (ages 7-12) in an exploration of the natural world. The app allows children to build, curate and share photo collections through individual challenges and simple photo classification walkthroughs. The app will also seek to facilitate collaborative play through team scavenger hunts and photo challenges. We piloted an app evaluation with 8 children in a botanic garden. Initial qualitative observations suggest promising results for the effectiveness of NatureCollections to draw children’s attention to their natural surroundings and spark playful social interactions. In the upcoming months, we plan to qualitatively and quantitatively assess the app’s ability to motivate children to spend more time outside. Later, we plan to deploy the app to evaluate its effect in increased connectedness to nature in situ. We believe the Workshop on Playing Together: the importance of joint engagement in the design of technology for children will be an excellent venue to discuss our design work and pilot results. We are also excited to learn from other real world case studies presented at the workshop on how we could focus our app interactions on co-engaging children with the natural context around them.
Read moreTechnological Nature: Adaptation and the Future of Human Life
Why it matters that our relationship with nature is increasingly mediated and augmented by technology. Our forebears may have had a close connection with the natural world, but increasingly we experience technological nature. Children come of age watching digital nature programs on television. They inhabit virtual lands in digital games. And they play with robotic animals, purchased at big box stores. Until a few years ago, hunters could “telehunt”—shoot and kill animals in Texas from a computer anywhere in the world via a Web interface. Does it matter that much of our experience with nature is mediated and augmented by technology? In Technological Nature, Peter Kahn argues that it does, and shows how it affects our well-being. Kahn describes his investigations of children’s and adults’ experiences of cutting-edge technological nature. He and his team installed “technological nature windows” (50-inch plasma screens showing high-definition broadcasts of real-time local nature views) in inside offices on his university campus and assessed the physiological and psychological effects on viewers. He studied children’s and adults’ relationships with the robotic dog AIBO (including possible benefits for children with autism). And he studied online “telegardening” (a pastoral alternative to “telehunting”). Kahn’s studies show that in terms of human well-being technological nature is better than no nature, but not as good as actual nature. We should develop and use technological nature as a bonus on life, not as its substitute, and re-envision what is beautiful and fulfilling and often wild in essence in our relationship with the natural world.

Figure 1. Examples of technological nature. HDTV plasma “windows” displaying real-time images of the local nature scene outside the building are shown (a) installed in a participant’s office in a long-term field study (Friedman, Freier, Kahn, Lin, & Sodeman, 2008); and (b) covering up a real window in the plasma-window condition of an experimental study in the lab (Kahn et al., 2008). The camera that recorded looking behavior can be seen poking out from the drapes to the left of the plasma window. The plasma screen was not present in the glass-window condition of the experimental study; and the drapes were pulled across the entire wall for the blank-wall condition. The bottom pictures show technological nature in the form of a robot dog (AIBO; from Kahn, Friedman, Perez-Granados, & Freier, 2006). In (c), the participant has just been introduced to AIBO and approaches the robot a little apprehensively. Within a couple of seconds, AIBO begins to move toward the participant; in (d), the participant is startled and appears slightly apprehensive (not unlike how a person might respond when encountering a biological dog that he or she has never met before). Two world trends are powerfully reshaping human existence: the degradation, if not destruction, of large parts of the natural world, and unprecedented technological development. At the nexus of these two trends lies technological nature—technologies that in various ways mediate, augment, or simulate the natural world. Current examples of technological nature include videos and live webcams of nature, robot animals, and immersive virtual environments. Does it matter for the physical and psychological well-being of the human species that actual nature is being replaced with technological nature? As the basis for our provisional answer (it is ‘‘yes’’), we draw on evolutionary and cross-cultural developmental accounts of the human relation with nature and some recent psychological research on the effects of technological nature. Finally, we discuss the issue—and area for future research— of ‘‘environmental generational amnesia.’’ The concern is that, by adapting gradually to the loss of actual nature and to the increase of technological nature, humans will lower the baseline across generations for what counts as a full measure of the human experience and of human flourishing. Technology has begun to change our species’ long-standing experiences with nature. Now we have technological nature—technologies that in various ways mediate, augment, or simulate the natural world. Entire television networks, such as the Discovery Channel and Animal Planet, provide us with mediated digital experiences of nature: the lion’s hunt, the Monarch’s migration, or a climb high into the Himalayan peaks. Video games like Zoo Tycoon engage children with animal life. Zoos themselves are bringing technologies such as webcams into their exhibits so that we can, for example, watch animals from the leisure of our home or a café. Inexpensive robot pets have been big sellers in the Wal-Marts and Targets of the world. Sony’s higher-end robot dog AIBO sold well. Real people now spend substantial time in virtual environments (e.g., Second Life). In terms of the physical and psychological well-being of our species, does it matter that we are replacing actual nature with technological nature? To support our provisional answer that it does matter, we draw on evolutionary and cross-cultural developmental accounts of the human relation with the natural world and then consider some recent psychological research on the effects of technological nature.

Figure 1. HDTV Camera (circled) mounted on the roof of the university building (left). Brin at work in her office with the plasma display window (right). We installed large plasma displays on the walls of seven inside offices of faculty and staff at a university, and displayed, as the default image, real-time HDTV views of the immediate outside scene. Then, utilizing a field-study methodology, data were collected over a 16-week period to explore the user experience with these large display windows. Through the triangulation of data—652 pages of interview transcripts, journal entries, and responses to email inquiries—results showed that users deeply appreciated many aspects of their experience. Benefits included a reported increase in users’ connection to the wider social community, connection to the natural world, psychological wellbeing, and cognitive functioning. Users also integrated the large display window into their workplace practice. However, users expressed concerns particularly about the impacts on the privacy of people whose images were captured in the public place by the HDTV camera. Discussion focuses on design challenges for future investigations into related uses of large displays.

Figure 2. Heart rate recovery from low-level stress. Values are the mean slope of heart rate (in beats per minute per minute (bpm/min)) during the first 60 s of each activity. Negative values indicate decreasing heart rate, and points lower on the graph represent more rapid decreases in heart rate. (The activities are ordered by the overall average slope across all six activities.) Humans will continue to adapt to an increasingly technological world. But are there costs to such adaptations in terms of human well being? Toward broaching this question, we investigated physiological effects of experiencing a HDTV quality real-time view of nature through a plasma display “window.” In an office setting, 90 participants (30 per group) were exposed either to (a) a glass window that afforded a view of a nature scene, (b) a plasma window that afforded a real-time HDTV view of essentially the same scene, or (c) a blank wall. Results showed that in terms of heart rate recovery from low-level stress the glass window was more restorative than a blank wall; in turn, a plasma window was no more restorative than a blank wall. Moreover, when participants spent more time looking at the glass window, their heart rate tended to decrease more rapidly; that was not the case with the plasma window. Discussion focuses on how the purported benefits of viewing nature may be attenuated by a digital medium.

Figure 1. a. Student taking a close-up shot of a flower b. One student pointing nature element to her peers a c. Students walking and scanning their surroundings. In this study, we investigate whether and how a mobile application called NatureCollections supports children’s triggered situational interest in nature. Developed from an interest-centered design framework, NatureCollections allows children to build and curate their own customized photo collections of nature. We conducted a comparison study at an urban community garden with 57 sixth graders across 4 science classrooms. Students in two classrooms (n = 15 and 16) used the NatureCollections app, and students in another two classrooms (n = 13 and 13) used a basic Camera app. We found that NatureCollections succeeded in focusing students’ attention–an important aspect of interest development– through sensory engagement with the natural characteristics in their surroundings. Students who used NatureCollections moved slower in space while scanning their surroundings for specific elements (e.g., flowers, birds) to photograph. In contrast, students who used the basic Camera app were more drawn to aesthetic aspects (e.g., color, shape) and tended to explore their surroundings through the device screen. NatureCollections supported other dimensions of interest development, including personal relevance, social interactions, and positive experiences for continued engagement. Our findings further showed that the NatureCollections app facilitated students’ scientific discourse with their peers.
