  • The purpose of this study was to investigate the effect of HMD-based virtual reality core nursing skills training on nursing students' knowledge, performance, self-confidence, self-efficacy, and problem-s olving ability. The study participants were 45 fourth-year nursing students from a university in A city. The participants were assigned to either the experimental group (n = 21) who received VR core nursing skills related to blood transfusion training or the control group (n = 24) who received traditional training using mannequins. After completing core nursing skill training, the experimental group and the control group performed simulations including blood transfusion. Data was collected from October 3 to October 28, 2022. The collected data were analyzed using descriptive statistics and t-tests. The results showed that after the intervention, the experimental group had significantly higher knowledge scores than the control group (t=-2.13, p=.039). The control group had significantly higher self-confidence in performance than the experimental group (t=2.63, p=.012). There were no significant differences in performance, self-efficacy, or problem-solving ability between the two groups. Therefore, VR-based core nursing skills training can be usefully utilized for nursing students to learn the knowledge and procedures before performing them in real life, and traditional core nursing skills training using mannequins can lead to an increase in nursing students' confidence in performing the skills.

  • Home modification has come to be recognized as an important intervention strategy to manage health care conditions, maintain or improve functioning, ensure safety, and reduce the wheelchair user's dependency on others. However, the availability of skilled professionals with experience in home modifications for accessibility is limited. A system that enables accurate remote assessments would be an important tool to improve our ability to perform home assessments more easily and at decreased cost. A Remote Wheelchair Accessibility Assessment System (RWAAS) using Virtualized Reality(VR) technology was developed that enabled clinicians to assess the wheelchair accessibility of users' built environments from a remote location. Characteristics of the camera and 3D reconstruction program chosen for the system significantly affect its overall reliability. In this study, we performed two reliability analyses on the hardware and software components: 1) Verification that commercial software can construct sufficiently accurate 3D models by analyzing the accuracy of dimensional measurements in a virtualized environment; 2) comparison of dimensional measurements with four camera settings. Based on these two analyses, we were able to specify a consumer level digital camera and the Photomodeler Pro software for this system. And we then tested the feasibility of the selected software and hardware in an actual environment. Lastly, A field evaluation was performed to test whether this new system is comparable to the traditional method of accessibility assessment to evaluate its ability to assess the accessibility of a wheelchair user's typical built environment. The results of field trials showed high congruence between the assessments by two methods. Findings suggested that the RWAAS assessments have the potential to enable specialists to assess potential accessibility problems in built environments regardless of the location of the client, home, or specialist.

  • Early diagnosis of autism and intervention of medical treatment are very significant to develop specific social communication skill for children with autistic spectrum disorders (ASDs). But they have difficulties in medical treatment because of lack of a public welfare institution and special medical system. In particular, few children can access such treatment and the existing single-therapist clinics are inefficient with regard to cost and time. Therefore, new methods should be studied for developing various products, services, and systems for autistic children. This study discusses the potential use of an interactive design as assistive technology for such children. We utilize the experience gained in the collaborative design of the interactive therapy system (ITS). The key methods include a collaborative design with rapid interactive prototyping, heuristic evaluation, user-centered process, VR technology, tangible interface, and scenario-based contents. We applied these methods to the ITS and proved the efficiency of interactive design as an assistive technology through clinical experimentation.
