“…Similarly, virtual environments might be used to teach youth about the risks of ATV operation. A greater step, but still feasible, may be virtual environment applications that train adolescents in the risks of unsafe sex, drug and alcohol use, and high-risk adventure sports, or that treat individuals with wide-ranging problems such as difficulty with stress management (Serino et al 2013), sexual deviance (Renaud et al 2013), or treatment of mental illnesses like anxiety and schizophrenia (Gutiérrez-Maldonado et al 2013; Spanolli et al 2013). As today's society, and especially today's youth, use the internet with increasing frequency, educational applications and games they can access on computers, tablets, and phones offer a unique opportunity to provide health-related training to children and adolescents.…”

Usability and feasibility of an internet-based virtual pedestrian environment to teach children to cross streets safely

Child pedestrian injury is a preventable global health challenge. Successful training efforts focused on child behavior, including individualized streetside training and training in large virtual pedestrian environments, are laborious and expensive. This study considers the usability and feasibility of a virtual pedestrian environment “game” application to teach children safe street-crossing behavior via the internet, a medium that could be broadly disseminated at low cost. Ten 7- and 8-year-old children participated. They engaged in an internet-based virtual pedestrian environment and completed a brief assessment survey. Researchers rated children's behavior while engaged in the game. Both self-report and researcher observations indicated the internet-based system was readily used by the children without adult support. The youth understood how to engage in the system and used it independently and attentively. The program also was feasible. It provided multiple measures of pedestrian safety that could be used for research or training purposes. Finally, the program was rated by children as engaging and educational. Researcher ratings suggested children used the program with minimal fidgeting or boredom. The pilot test suggests an internet-based virtual pedestrian environment offers a usable, feasible, engaging, and educational environment for child pedestrian safety training. If future research finds children learn the cognitive and perceptual skills needed to cross streets safely within it, internet-based training may provide a low-cost medium to broadly disseminate child pedestrian safety training. The concept may be generalized to other domains of health-related functioning such as teen driving safety, adolescent sexual risk-taking, and adolescent substance use.

“…In other words, offenders may approach the same potential sexual partner only under particular circumstances, such as when the potential partner is perceived to be inviting sexual contact. Sexual interests can be highly individual, making it difficult to develop stimuli that are general and inclusive to the entire sex offender population, while also specific to the scenarios an individual finds arousing (Kalmus & Beech, 2005;Renaud et al, 2009Renaud et al, , 2013Renaud et al, , 2014.…”

There are concerns regarding the reliability, realism, and validity of stimulus materials used in the assessment of sexual interests among sex offenders. This article explores new stimulus materials for use with penile plethysmography (PPG) assessments. First, this paper presents a pilot study where undergraduate students rated virtual characters (male and female) on perceived age. In addition, the materials developed are unique in that they depict the characters exhibiting varying affective dispositions, including neutral, fearful, sad, joyful, and seductive. Participants in the first study were also asked to identify the affective disposition of the virtual characters, and results suggest that affective disposition was largely perceived as intended, especially in terms of identifying the general emotional valence of the affective dispositions (i.e., positive versus negative). In a second pilot study, we used the computer-generated images to measure sexual arousal responses in a group of non-deviant males recruited in the community. Responses measured through penile plethysmography suggest participants responded to the stimuli as expected, as the greatest amount of sexual arousal was recorded when participants were shown the adult female character. In addition, participants responded with significant arousal only when the adult female character was depicted as sexually open ( joyful or seductive), rather than sexually closed or neutral. Results suggest these materials may discriminate sexual interests if applied within clinical forensic assessment of sex offenders.

“…VR can serve as a bridge between a closed setting and the outside world. Furthermore, VR can be used to validly assess offenders' behavioral and physiological responses to stimuli, for example by showing virtual young children to pedophiles [21]. Furthermore, VR can be used to overcome practical issues with exposure therapy.…”

In development, implementation and evaluation of eHealth it is essential to account for stakeholders' perspectives, opinions and values, which are statements that specify what stakeholders want to achieve or improve via a technology. The use of values enables developers to systematically include stakeholders' perspectives and the context of use in an eHealth development process. However, there are relatively few papers that explain how to use values in technology development. Consequently, in this paper we show how we formulated values during the multi-method, interdisciplinary and iterative development process of a VR application for a complex setting: forensic mental healthcare. We report the main foundations for these values: the outcomes of an online questionnaire with patients, therapists and other stakeholders (n=146) and interviews with patients and therapists (n=18). We show how a multidisciplinary project team used these qualitative results to formulate and adapt values and create lo-fi prototypes of a VR application. We discuss the importance of a systematic development process with multiple formative evaluations for eHealth and reflect on the role of values within this.
