■基于网络的身体活动干预措施往往无法达到预期的公共卫生影响,因为预期受众的使用不足。
■这项研究的目的是使用以人为本的设计过程来优化家庭网站中断长时间坐姿(InPACT)的用户体验,以促进青少年体育活动参与。
■进行了定性访谈,以评估InPACTatHome网站的参与度和痛点。采访数据用于创建亲和力图,以识别用户响应的主题,根据尼尔森的可用性启发式框架进行启发式评估,并完成竞争分析,以确定提供同类产品的竞争对手的优势和劣势。
■最终用户访谈的主要主题包括喜欢网站设计,发现网站难以导航,并想要额外的功能(例如,观看的视频库)。发现的网站可用性问题是缺乏运动视频的标签和分类,隐藏了阻碍用户决策的必要行动和选项,容易出错的条件,和网站的高认知负荷。竞争分析结果显示,YouTube获得了最高的可用性评级,其次是JustDance和President青年健身计划网站。
■以人为中心的设计方法有助于将最终用户和开发人员聚集在一起,以优化用户体验并影响公众健康。需要进行未来的研究来检查InPACTatHome网站重新设计以吸引新用户并保留当前用户的有效性,最终目标是增加青少年体育活动参与度。
UNASSIGNED: Web-based physical activity interventions often fail to reach the anticipated public health impact due to insufficient use by the intended audiences.
UNASSIGNED: The purpose of this study was to use a human-centered design process to optimize the user experience of the Interrupting Prolonged sitting with ACTivity (InPACT) at Home
website to promote youth physical activity participation.
UNASSIGNED: Qualitative interviews were conducted to assess engagement and pain points with the InPACT at Home
website. Interview data were used to create affinity maps to identify themes of user responses, conduct a heuristic evaluation according to Nielsen\'s usability heuristics framework, and complete a competitive analysis to identify the strengths and weaknesses of competitors who offered similar products.
UNASSIGNED: Key themes from end user interviews included liking the
website design, finding the
website difficult to navigate, and wanting additional features (eg, library of watched videos). The
website usability issues identified were lack of labeling and categorization of exercise videos, hidden necessary actions and options hindering users from decision-making, error-prone conditions, and high cognitive load of the website. Competitive analysis results revealed that YouTube received the highest usability ratings followed by the Just Dance and Presidential Youth Fitness Program websites.
UNASSIGNED: Human-centered design approaches are useful for bringing end users and developers together to optimize user experience and impact public health. Future research is needed to examine the effectiveness of the InPACT at Home website redesign to attract new users and retain current users, with the end goal of increasing youth physical activity engagement.
