可用性在家用康复护理床界面设计中的应用研究

发布时间：2018-11-12 08:21

【摘要】：此项目是社区康复(CBR)背景下的护理床界面设计,“家庭康复”是社区康复中最为重要的组成部分。传统的护理床一般由医护人员操作,操作界面往往复杂而专业,而家庭场景下的护理床则由普通家庭成员操作。家庭成员在康复护理知识、医疗器械操作知识方面均缺乏专业性。因此,如何提供一种易学、易用、可靠的“高可用性”操作界面是此项目的重点,“可用性”概念的引入也正是出于这样的考虑。首先,建立护理床界面可用性评估体系,明确护理床界面的可用性因子及其权重分布,从而确定护理床界面的可用性目标,指导界面设计；继而,通过“形成性可用性评估”,对护理床界面进行反复评估设计,从而得到最终的界面方案；最后,对护理床界面方案进行“总结性可用性评估”,依据上文中的可用性评估体系,从主客观方面对护理床界面方案进行全面的可用性评估。在护理床界面可用性评估体系建立的过程中：首先通过文献研究收集全面的常见可用性因子,并通过用户研究、场景任务研究对可用性因子进行初步筛选。接着,笔者在传统可用性分层模型的基础上建立了3F2M模型,将上述可用性因子整合进模型,得到初步的护理床可用性评估体系(无权重)。最后,通过AHP层次分析对评估体系中的因子进行赋权,得到最终的护理床界面可用性评估体系。在护理床界面设计及形成性评估中：采用反复评估设计的方式进行,评估方法以启发式评估为主,共进行3轮评估。每一轮评估输出设计方案的修改意见,由粗到细直至没有显著的可用性问题。在护理床界面的总结性评估中：依据第三章中的可用性评估体系,通过基于眼动的用户测试,对护理床界面方案进行系统全面的可用性评估。在测试过程中,除了记录眼动外还进行了回溯性访谈和满意度问卷调查。最终得到护理床界面的可用性评估表、可用性问题列表、界面再版建议。此研究的研究成果包括：建立了护理床界面的可用性评估体系；设计了一款具有高可用性的家用护理床界面；提出了护理床界面设计的可用性指导意见,并总结了护理床界面设计中的可用性设计方法；归纳了各类可用性评估方法在项目实践中的适用性,并给出了相关优化建议；
[Abstract]:This project is the design of nursing bed interface under the background of community rehabilitation (CBR). Family rehabilitation is the most important part of community rehabilitation. The traditional nursing beds are usually operated by medical staff. The operation interface is often complex and professional, while the nursing beds in family settings are operated by ordinary family members. Family members are lack of professional knowledge of rehabilitation nursing and operation of medical devices. Therefore, how to provide an easy-to-learn, easy-to-use, reliable "high availability" interface is the focus of this project, and the introduction of the concept of "usability" is out of this consideration. Firstly, the usability evaluation system of nursing bed interface is established, the availability factors and their weight distribution of nursing bed interface are defined, the usability goal of nursing bed interface is determined, and the design of nursing bed interface is guided. Then, through "formative usability evaluation", the nursing bed interface is repeatedly evaluated and designed, and the final interface scheme is obtained. Finally, the "summative usability evaluation" is carried out on the nursing bed interface scheme. According to the usability evaluation system mentioned above, the comprehensive usability evaluation of the nursing bed interface scheme is carried out from the subjective and objective aspects. In the process of establishing the usability evaluation system of nursing bed interface: firstly, the common usability factors were collected through literature research, and the usability factors were preliminarily screened through user research and scenario task study. Then, the author establishes the 3F2M model based on the traditional usability stratification model, integrates the above availability factors into the model, and obtains the primary usability evaluation system of nursing bed (no weight). Finally, the factors in the evaluation system are empowered by AHP hierarchy process, and the final usability evaluation system of nursing bed interface is obtained. In the design and formative evaluation of nursing bed interface, the method of repeated evaluation design was adopted. The evaluation method was mainly heuristic evaluation, and three rounds of evaluation were carried out. Each round assesses the revision of the output design from coarse to fine until there are no significant usability problems. In the summation evaluation of nursing bed interface: according to the usability evaluation system in the third chapter, through the user test based on eye movement, the comprehensive usability evaluation of nursing bed interface scheme is carried out. In addition to recording eye movements, retrospective interviews and satisfaction surveys were conducted during the test. Finally, the usability evaluation form, usability problem list and reprint suggestion of the nursing bed interface are obtained. The results of this study include: establishing the usability evaluation system of nursing bed interface, designing a high availability home nursing bed interface; The usability guidance of nursing bed interface design was put forward, and the usability design methods in nursing bed interface design were summarized, the applicability of various usability evaluation methods in project practice was summarized, and the relevant optimization suggestions were given.
