Driver’s gaze information can be crucial in driving research because of its relation to driver attention. Particularly, the inclusion of gaze data in driving simulators broadens the scope of research studies as they can relate drivers’ gaze patterns to their features and performance. In this paper, we present two gaze region estimation modules integrated in a driving simulator. One uses the 3D Kinect device and another uses the virtual reality Oculus Rift device. The modules are able to detect the region, out of seven in which the driving scene was divided, where a driver is gazing at in every route processed frame. Four methods were implemented and compared for gaze estimation, which learn the relation between gaze displacement and head movement. Two are simpler and based on points that try to capture this relation and two are based on classifiers such as MLP and SVM. Experiments were carried out with 12 users that drove on the same scenario twice, each one with a different visualization display, first with a big screen and later with Oculus Rift. On the whole, Oculus Rift outperformed Kinect as the best hardware for gaze estimation. The Oculus-based gaze region estimation method with the highest performance achieved an accuracy of 97.94%. The information provided by the Oculus Rift module enriches the driving simulator data and makes it possible a multimodal driving performance analysis apart from the immersion and realism obtained with the virtual reality experience provided by Oculus.

Objectives: Cardiopulmonary resuscitation (CPR) is lifesaving. Yet, cardiac arrest survival remains low despite CPR intervention. Education has been highlighted as a strategy to overcome this issue. Virtual Reality technology has been gaining momentum in the field of clinical education. Published studies report benefits of virtual reality for CPR education; yet, perceptions of CPR instructors towards virtual reality remain unexplored. CPR instructors are key stakeholders in CPR education and their perceptions are valuable for the design and adoption of virtual reality-enhanced learning. The purpose of this study is therefore to understand the perceptions of CPR instructors towards using virtual reality for health professionals’ CPR education. The aim was addressed via three research questions: (1) What are the perceptions of CPR instructors towards current health professionals’ CPR education? (2) What are the perceptions of CPR instructors towards features of virtual reality ideal for health professionals’ CPR education? (3) What are the perceptions of CPR instructors towards the potential role of virtual reality in health professionals’ CPR education? Methods: A total of 30 CPR instructors were surveyed on their views towards current health professionals’ CPR education and the use of virtual reality for health professionals’ CPR education, before and after interacting with a CPR virtual reality simulation. Responses were analysed using interpretative thematic analysis. Results: CPR instructors perceived current health professionals’ CPR education as limited due to unideal test preparation (resources, practice, motivation, and frame of mind) and performance. They perceived fidelity, engagement, resource conservation, and memory enhancement as features of virtual reality ideal for health professionals’ CPR education. Virtual reality was viewed by CPR instructors as having potential as a blended learning tool, targeting both ‘novice’ and ‘experienced’ health professionals. Conclusion: The study highlighted the gaps in current health professionals’ CPR education that can be addressed using virtual-reality-enabled learning. Future research could investigate virtual reality simulations with features desirable for CPR education of target populations.

Purpose–The study aims to develop an application that will serve as an alternative learning tool for learning Asian Studies. The delivery of lessons into a virtual reality game dependson the pace of students. The developed application comprises several more features that enable users to get valuable information from an immersive environment.Method–The researchers used Rapid Application Development (RAD) in developing the application. It follows phases such as requirement planning, user design, construction, and cutover. Two sets of questionnaires were developed, one for the teachers and another for the students. Then, testing and evaluation were conducted through purposive sampling to select the respondents.Results–The application was overall rated as 3.56 which is verbally interpreted as very good. The result was based on the system evaluation using ISO 9126 in terms of functionality, usability, content, reliability, and performance. 476Conclusion–The developed application meets the objectives to provide an alternative learning tool for learning Asian Studies. The application is well commended and accepted by the end-users to provide an interactive and immersive environment for students to learn at their own pace. Recommendations–Further enhancement of the audio, gameplay, and graphics of the tool. Schools should take into consideration the adoption of the Asian Studies Virtual Reality as a good alternative tool for their teachers and students to teach and learn Asian Studies. The use of more 3D objects relevant to the given information to enhance game experience may be considered.A databank for the quiz questions that will be loaded into the game should also be considered.Research Implications–The integration of modern technology in education has been a vital part of the learning process, especially when technological resources are available. Development and adaptation of this application will promote an alternative way of independent learning among students and will give them a better understanding of Asian Studies at their own pace.

Abstract Purpose: To study the usefulness of virtual reality (VR) based training for diagnosing strabismusMethods: Fourteen ophthalmology residents performed at least 30 VR training sessions to diagnose esotropia and exotropia. Examinations of real patients with esotropia or exotropia before and after the VR training were video-recorded and presented to a strabismus expert to assess accuracy and performance scores for measuring the deviation angle and diagnosing strabismus with anonymization. A feedback survey regarding the usefulness and ease of use of the VR application was conducted for participants.Results: The mean age of 14 ophthalmology residents, including 10 men and 4 women, was 29.7 years. Before VR training, participants showed a mean accuracy score of 14.50 ± 5.45 and performance score of 9.64 ± 4.67 for measuring the deviation angle and diagnosing strabismus in real patients with strabismus. After VR training, they showed a significantly improved accuracy score of 22.14 ± 4.37 (p = 0.012) and performance score of 15.50 ± 1.99 (p = 0.011). According to the survey, most participants agreed on the usefulness of VR application.Conclusions: This study suggests that VR based training improves ophthalmology residents’ clinical diagnostic skills for strabismus in a short period.
