Abstract

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Approximately 1.13 billion people suffer from arterial hypertension (AH), a condition that stands out among all other CVD risk factors. One of the main non-pharmacological treatments for AH is the performance of physical activities. Studies have also demonstrated the possibility of blood pressure control through the application of breathing exercises. Such exercises can be performed even at home. Due to the limitations concerning physical exercise for patients with uncontrolled hypertension, clinicians often have their patients conduct breathing exercises before a physiotherapy session for blood pressure reduction purposes. However, more tools are needed to assist clinicians with this approach. Considering these circumstances, this paper introduces PhysioAR, an augmented reality system designed to assist in respiratory therapy treatments for hypertensive patients. Using three-dimensional virtual environments and specific hardware for vital sign measurements, PhysioAR enables the creation and application of respiratory therapy sessions by a physiotherapist professional. At the end of its development, a group of usability experts evaluated the system through a questionnaire based on Nielsen's heuristic evaluation of user interfaces. After evaluation, PhysioAR obtained an average performance of 4.3 by the Likert scale. All evaluators agreed that using the system was a pleasant experience, which suggests that PhysioAR has potential for physiotherapy clinics. The questionnaire application exposed some user experience problems. This demonstrated the effectiveness of a questionnaire-based evaluation to identify possible system problems.

PhysioAR:一种用于高血压患者呼吸物理治疗的增强现实系统
心血管疾病(cvd)是世界范围内死亡的主要原因。大约有11.3亿人患有动脉高血压(AH),这是所有其他心血管疾病风险因素中最突出的一种。AH的主要非药物治疗方法之一是体育活动的表现。研究也证明了通过呼吸练习控制血压的可能性。这样的练习甚至可以在家里进行。由于高血压未控制患者的体育锻炼的局限性,临床医生经常让患者在物理治疗前进行呼吸练习,以达到降血压的目的。然而,需要更多的工具来帮助临床医生采用这种方法。考虑到这些情况,本文介绍了PhysioAR,一种增强现实系统,旨在协助高血压患者的呼吸治疗。PhysioAR使用三维虚拟环境和特定硬件进行生命体征测量,使物理治疗师专业人员能够创建和应用呼吸治疗课程。在开发结束时,一组可用性专家通过基于尼尔森用户界面启发式评估的问卷对系统进行了评估。经评估,PhysioAR在Likert量表中获得平均4.3分。所有评估人员一致认为使用该系统是一种愉快的体验,这表明PhysioAR在物理治疗诊所具有潜力。问卷调查应用程序暴露了一些用户体验问题。这证明了基于问卷的评估识别可能的系统问题的有效性。
