| dc.description.abstract | Immersive technologies have been utilized in nursing education and other disciplines as effective learning and teaching tools. Many virtual reality (VR) simulations provide users immersive experiences through audiovisual stimuli. However, these systems do not enable haptic and tangible interactions, preventing them from utilizing higher multisensory stimuli for learning. There is a need in nursing education for more realistic VR experiences that allow direct hand manipulation in the acquisition of assessment skills, especially Leopold’s Maneuvers which require palpating the patient’s abdomen. To meet this need, a haptic-enabled virtual reality simulation called Leopold’s Maneuvers VR was developed. This application utilized a set of commercial haptic gloves called SenseGlove to allow users to touch and feel the virtual patient’s abdomen and fetus in the virtual exam room. To investigate the quality of haptic interactions from Leopold’s Maneuvers VR, two sets of user studies were conducted. Study 1 was an explorative haptic experience study to investigate the effectiveness and usability of the haptic interactions. Study1 included three tasks to evaluate four different haptic device settings and a subjective post-study questionnaire to measure sense of presence for each device. Four different haptic device settings consisted of VIVE controller, SenseGlove, Custom-made Vibration glove, and the combination of Vibration glove and SenseGlove. The results show that SenseGlove showed the highest performance in task 1 and Vibration glove showed highest performance in task 2 and 3. According to the quantitative analysis, the combination of the SenseGlove and the Vibration glove provided the highest presence.
Study 2 was conducted with three of the haptic devices which showed high performance and presence. Study 2 investigated haptic interactions in the Leopold’s Maneuvers process using Leopold’s Maneuvers VR application. Most participants showed improvements in Leopold's Maneuvers knowledge after using the application and expressed positive feedback about using haptic devices in the application. This implies that the application may prove to be an effective educational tool in nursing education. In the future, we would like to improve the application based on the user feedback and conduct user studies with more students. | |
