Cognitive load and performance in immersive virtual reality versus conventional virtual reality simulation training of laparoscopic surgery: a randomized trial.

Virtual reality simulators combined with head-mounted displays enable highly immersive virtual reality (VR) for surgical skills training, potentially bridging the gap between the simulation environment and real-life operating room conditions. However, the increased complexity of the learning situation in immersive VR could potentially induce high cognitive load thereby inhibiting performance and learning. This study aims to compare cognitive load and performance in immersive VR and conventional VR simulatio...

Augmented reality and virtual reality in the operating theatre status quo und quo vadis.

 Virtual reality (VR) is an artificially simulated environment permitting interaction. On the other hand, augmented reality (AR) is an enhanced version of reality created by the use of technology to overlay digital information on an image of something being viewed through a device. Both technologies have partially been implemented in clinical daily routine. Surgical applications of VR and AR are currently evaluated. Yet it is still unclear which possibilities these new and versatile applications offer for...

Equivalence of using a desktop virtual reality science simulation at home and in class.

The use of virtual laboratories is growing as companies and educational institutions try to expand their reach, cut costs, increase student understanding, and provide more accessible hands on training for future scientists. Many new higher education initiatives outsource lab activities so students now perform them online in a virtual environment rather than in a classroom setting, thereby saving time and money while increasing accessibility. In this paper we explored whether the learning and motivational ou...

According to a signifcant number of publications including meta-analysis, virtual reality therapy exposure is at least equivalent to in vivo exposure in specifc phobias, panic diso...

The Effect of Variations in Force Feedback in a Virtual Reality Environment on the Performance and Satisfaction of Dental Students.

The aim of this study was to investigate the transfer of skills between various levels of force feedback (FFB) using the Simodont dental trainer (Moog, Nieuw-Vennep, the Netherlands). Students practiced a manual dexterity exercise in a virtual reality environment at a standard level of FFB and then were tested at the standard and an altered level of FFB. In addition, the students' satisfaction with the training exercise was evaluated.

Observing the stages of bystander intervention in virtual reality simulation.

Understanding bystander reactions to an emergency is an important component of effective training. Four stages of bystander intervention (BI) have been previously described: noticing the situation as a problem, interpreting when it is appropriate to intervene, recognizing personal responsibility to intervene, and knowing how to intervene. Using virtual reality (VR) to simulate emergencies such as sudden cardiac arrest (SCA) can be used to study these stages.

Developing a Virtual Reality Environment for Mining Research.

Recent advances in computing, rendering, and display technologies have generated increased accessibility for virtual reality (VR). VR allows the creation of dynamic, high-fidelity environments to simulate dangerous situations, test conditions, and visualize concepts. Consequently, numerous products have been developed, but many of these are limited in scope. Therefore, the National Institute for Occupational Safety and Health researchers developed a VR framework, called VR Mine, to rapidly create an undergr...

Using Low-Cost Virtual Reality Simulation to Build Surgical Capacity for Cervical Cancer Treatment.

Worldwide, more than 80% of people diagnosed with cancer will require surgery during their disease course, but only 5% to 20% of low- and middle-income countries have access to safe, affordable, and timely surgery. Developing surgical oncology skills requires significant time and mentoring. Virtual reality (VR) simulators can reduce the time required to master surgical procedures but are prohibitively expensive. We sought to determine whether a VR simulator using low-cost computer gaming equipment could tra...

Is virtual reality useful for pain management in patients who undergo medical procedures?

Pain management is a complex medical issue, and many efforts have been done to develop new non-pharmacological therapies. Virtual reality is a technology apparatus that make an interaction between human and virtual environment through an hardware (usually a headset) linked to a computer or a mobile, by using a software. Additionally, this virtual setting can be adapted to any type of scenario. Thus, it is plausible that the software used should be personalized depending on patient's experiences and expectat...

Virtual Reality Simulation in Peritoneal Dialysis Training: The Beginning of a New Era.

Peritonitis rates in peritoneal dialysis (PD) vary considerably not only across countries but also between centers in the same country. Patient education has been shown to significantly reduce infection rates but up till now training lacks standardization with patients being trained using different methods and media (e.g., illustrations, videos). As a result, patients may be insufficiently experienced in performing PD, which might be one of the causes for high peritonitis rates. To address these issues, we ...
