study protocol a randomised non inferiority trial using interactive Virtual Presence to remotely assist parents with child restraint installations
Injury Prevention, 2020Co-Authors: David C Schwebel, Jennifer Morag Mackay, David T ReddenAbstract:Background Motor vehicle crashes are the third-leading cause of death to American children aged 1–5 years. When installed correctly, child restraints (car seats) reduce risk of serious injury and death. However, most restraints are installed incorrectly. The current gold standard for correct installation is systematic car seat checks, where certified technicians help parents, but car seat checks are highly underused due to barriers in access, scheduling and resources. Methods The present study protocol describes plans to evaluate use of interactive Virtual Presence technology (interactive merged reality)—joint, simultaneous remote verbal and visual interaction and exposure to the same 3D stimuli—to assist remotely located parents installing child restraints. If effective, this technology could supplement or replace in-person checks and revolutionise how government, industry and non-profits help parents install child restraints properly. Building from preliminary studies, we propose a randomised non-inferiority trial to evaluate whether parents who install child restraints while communicating with remote expert technicians via interactive Virtual Presence on their smartphones achieve installations and learning not inferior in safety to parents who install restraints with on-site technicians. We will randomly assign 1476 caregivers at 7 US sites to install child restraints either via interactive Virtual Presence or live technicians. Correctness of installation will be assessed using objective checklists, both following installation and again 4 months later. Conclusion We aim to demonstrate that child restraint installation is accurate (>90% correct) when conducted remotely, that such installations are not inferior to installation accuracy with live experts and that parents learn and retain information about child restraint installation.

Supporting caregiver use of child restraints in rural communities via interactive Virtual Presence
Health education & behavior : the official publication of the Society for Public Health Education, 2019Co-Authors: Marissa Swanson, Morag Mackay, Alexis Kagiliery, Koren Bloom, David C SchwebelAbstract:When used correctly, child restraint systems (CRS) effectively reduce the risk of serious injury and death to child passengers in motor vehicle crashes. However, error rates in CRS use among caregivers are extremely high. Consultation with child passenger safety technicians (CPST) reduces misuse rates, but access to CPST is limited, particularly in rural areas. Remote consultation via interactive Virtual Presence (IVP) may increase access to CPST. One hundred and fifty caregivers in Southeast Montana completed remote consultation with CPST via IVP. Errors in CRS selection, installation, and child positioning were coded at baseline and postintervention in a within-subjects, pretest-posttest design. The proportion of caregivers making one or more errors in CRS selection (McNemar's test p < .001) and installation (McNemar's test p < .001), but not child positioning, significantly decreased following remote consultation. IVP is a promising mobile health (mHealth) strategy for providing remote consultation with CPST to improve rates of correct CRS use and mitigate child injury risk.

using interactive Virtual Presence to support accurate installation of child restraints efficacy and parental perceptions
Journal of Safety Research, 2017Co-Authors: David C Schwebel, Alison M Tillman, Marie Crew, Matthew Muller, Anna JohnstonAbstract:Abstract Introduction Child restraint systems (car seats) reduce injury risk for young children involved in motor-vehicle crashes, but parents experience significant difficulty installing child restraints correctly. Installation by certified child passenger safety (CPS) technicians yields more accurate installation, but is impractical for broad distribution. A potential solution is use of interactive Virtual Presence via smartphone application (app), which permits “hands on” teaching through simultaneous and remote joint exposure to 3-dimensional images. Method In two studies, we examined the efficacy of remote communication via interactive Virtual Presence to help parents install child restraints. Study 1 was conducted at existing car seat checkpoints and Study 2 at preschools/daycare centers. In both cases, existing installations were assessed by certified CPS technicians using an objective coding scheme. Participants then communicated with remotely-located certified CPS technicians via a smartphone app offering interactive Virtual Presence. Technicians instructed participants to install child restraints and then the installation was inspected by on-site technicians. Both before and after the remote interaction, participants completed questionnaires concerning perception of child restraints and child restraint installation, self-efficacy to install child restraints, and perceived risk of injury to children if they were in a crash. Results In both studies, accuracy of child restraint installations improved following the remote interaction between participants and certified CPS technicians. Together, the two samples achieved a weighted average of 90% correct installations across a multi-point inspection. Both samples reported increased self-efficacy to install child restraints and altered perceptions about the accuracy of the child restraint installations in their vehicles. Conclusions Findings support use of interactive Virtual Presence as a strategy to realize accurate installation of child restraints. Practical applications Interactive Virtual Presence between certified CPS technicians and the public via smartphone app has potential to improve proper child restraint installations broadly, including to vulnerable and underserved rural populations.

the influence of Virtual Presence effects on experienced cognitive load and learning outcomes in educational computer games
Computers in Human Behavior, 2012Co-Authors: Claudia Schrader, Theo BastiaensAbstract:Does the immersive design of an educational gaming environment affect learners' Virtual Presence and how much do they learn? Does Virtual Presence affect learning? This study tries to answer these questions by examining the differences in Virtual Presence and learning outcomes in two different computer-based multimedia environments: a gaming environment with high immersive design vs. hypertext learning environment with low immersive design. As the main focus, the effect of Virtual Presence on learning is also explained and tested. By identifying Virtual Presence as a variable that may determine learning, it is argued that computer gaming environments present a new challenge for researchers to investigate, particularly, the effects of Virtual Presence on the immersive design of games in order to help designers to predict which instructional configurations will maximize learning performance. In general, results revealed that the high-immersive gaming environment leads to the strongest form of Virtual Presence but also decreased learning. Although regression analyses indicate that Virtual Presence positively influences trivial- and non-trivial learning outcomes, learners who learned in a low-immersive environment outperformed the gaming group. A mediation analysis showed that the relation between Virtual Presence and non-trivial learning outcomes is partly mediated through increased cognitive load.

Towards a conceptual framework of direct and indirect environmental effects of co-working
'Association for Computing Machinery (ACM)', 2020Co-Authors: Vaddadi Bhavana, Bieser Jan, Pohl Johanna, Kramers AnnaAbstract:Through Virtual Presence, information and communication technology (ICT) allows employees to work from places other than their employer’s office and reduce commuting- related environmental effects (telecommuting). Co-working, as a form of telecommuting, has the potential to significantly reduce commuting and is not associated with deficits of working from home (e.g. isolation, lack of focus). However, environmental burden might increase through co-working due to the infrastructure required to set-up and operate the co-working space and potential rebound effects. In this paper, we (1) develop a framework of direct and indirect environmental effects of co- working based on a well-known conceptual framework of environmental effects of ICT and, (2) apply the framework to investigate the case of a co-working living lab established in Stockholm. Based on actual data of the co-working space and interviews conducted with participants, we roughly estimate associated energy impacts. Results show that energy requirements associated with operating the co-working space can counterbalance commute-related energy savings. Thus, in order to realize energy savings co-working should be accompanied with additional energy saving measures such as a net reduction of (heated) floor space (at the CW space, at the employer's office and the co-workers home) and use of energy-efficient transport modes

2020Co-Authors: Vaddadi Bhavana, Bieser Jan, Pohl Johanna, Kramers AnnaAbstract:Through Virtual Presence, information and communication technology (ICT) allows employees to work from places other than their employers office and reduce commuting-related environmental effects (telecommuting). Working from a local coworking space, as a form of telecommuting, has the potential to significantly reduce commuting and is not associated with deficits of working from home (e.g. isolation, lack of focus). However, environmental burden might increase through co-working due to the infrastructure required to set-up and operate the co-working space and potential rebound effects. In this paper, we (1) develop a framework of direct and indirect environmental effects of coworking based on a well-known conceptual framework of environmental effects of ICT and, (2) apply the framework to investigate the case of a coworking living lab established in Stockholm. Based on interviews and surveys conducted with co-workers in the living lab and infrastructure data of the co-working space, we roughly estimate associated energy impacts. Results show that energy requirements associated with operating the coworking space can counterbalance commute-related energy savings. Thus, in order to realize energy savings co-working should be accompanied with additional energy saving measures such as a net reduction of (heated) floor space(at the co-working space, at the employer's office and the co-workers home) and use of energy efficient transport modes.Comment: Conference- ICT4S 2020, Bristol, UK 9 pages, 4 images, 2 table
