| Summary: | 碩士 === 國立臺中科技大學 === 資訊工程系碩士班 === 100 === The advent of virtual reality (VR) environments represents a shift from textbased online learning environments to more immersive platforms. Augmented Reality (AR) combines real world and virtual objects and extends part of virtual reality. The role of virtual environments is able to visualize the location of other participants in order to action and increase the presence for students. In this research, I established a human anatomy learning system-3D-Health Care (3DHC) for two kinds of interface. The interfaces enable learners to study the content of human organs. One is the interface of Virtual Reality (3DHC-VR), and the other is the interface of Augmented Reality (3DHC-AR). In this study, two groups of the participants used the same content with different interfaces; one group studied a Virtual Reality model of the human abdominal anatomy in a stereoptic condition, and the other group studied the same anatomy in an Augmented Reality condition. After using the system, the participants filled in the questionnaires for analysis of the experimental results and I evaluated the perception of the users on the proposed 3DHC system with different interfaces.
By the quantitative data analysis, the main findings were as follows: (1) No matter what kind of interface could be use, the results of one-group pretest-posttest and pair-sample t test were evaluated to be statistically significant and indicated that the content of 3DHC helped to improve the effectiveness of learning. (2)Compared with 3DHC-VR and 3DHC-AR, the group of participants who used 3DHC-AR had more intention and better achievement. The group of participants who used 3DHC-VR had less cognitive load and higher motivation for learning.
