AR simulation for radiographic positioning(2018-2019)

We focused on learning that improves skills while using students’ physical senses and developed a simulation using augmented reality to teach body positioning for radiography. This simulation allows students to simulate angle placement repeatedly by using both their hands without positioning aids and angle gauges. The simulation was used in radiography practical training and a questionnaire survey was conducted after the class (Layout_&_Rawdata.xlsx). The responses ‘not confident’ and ‘not very confident’ accounted for 71% (χ2 = 7.05, p = 0.008) of a question regarding the students’ perception of their confidence using computer technology (ChisquaredTest.html). All students responded positively to question 1 and questions 3–6 that were regarding learning using the simulation. However, there were a certain number of ‘neither agree nor disagree’ (n = 12, 29%) or ‘disagree’ (n = 2, 5%) responses for question 2. There was no significant correlation between the responses to question 2 and those of students’ computer confidence levels (ρ = −0.03, p = 0.13) (Polychoric_correlation_coefficient.html).本研究聚焦于依托学生躯体感官参与的技能提升型学习模式，开发了一款基于增强现实（Augmented Reality）的模拟系统，用于教授放射摄影术中的体位摆放操作。该模拟系统允许学生无需借助体位辅助工具与角度规，仅通过双手即可反复模拟角度摆放动作。本模拟系统应用于放射摄影术实操训练环节，并于课后开展了问卷调查（配套数据文件：Layout_&_Rawdata.xlsx）。在针对学生计算机技术使用自信心的调研问题中，选择“不自信”与“不太自信”的受访者占比达71%（χ²=7.05，p=0.008），对应分析报告见ChisquaredTest.html。所有学生均对问题1与问题3至6作出了正向反馈，上述问题均围绕该模拟系统的学习体验设置。但针对问题2的反馈中，存在一定比例的“中立”（n=12，占比29%）与“不同意”（n=2，占比5%）的选择结果。问题2的反馈结果与学生的计算机自信心水平之间未发现显著相关性（ρ=-0.03，p=0.13），对应分析报告见Polychoric_correlation_coefficient.html。
