移动机器人远程呈现系统需要有关环境的信息,任务,并且机器人被呈现给远程定位的用户(操作者),其控制机器人以执行特定任务。在这项研究中,两种交互模式,主动和被动,用户从机器人接收信息的方式不同,在模拟医疗保健环境的实验系统中进行了比较。用户控制着一个移动远程呈现机器人,该机器人交付和接收物品(药物,食物,或饮料),在用户执行次要医疗保健相关任务时,还从模拟患者获得了指标(生命体征)(他们汇编了健康记录,这些记录显示在屏幕上并回答了相关问题)。通过参与者内部研究设计,评估了两种交互模式对整体表现和用户感知的影响,其中50名参与者属于两种不同类型的人群(有或没有技术背景)。效率,有效性,理解,满意,情境意识被定义为客观和主观测量的因变量。主动模式提高了用户性能,与反应模式相比,减少了工作量。然而,一些用户重视在反应模式中体验的增加用户控制的选项。我们,因此,提出了设计建议,以强调将反应模式作为混合模式纳入设计的一些好处。
Mobile robotic telepresence systems require that information about the environment, the task, and the robot be presented to a remotely located user (operator) who controls the robot for a specific task. In this study, two interaction modes, proactive and
reactive, that differ in the way the user receives information from the robot, were compared in an experimental system simulating a healthcare setting. The users controlled a mobile telepresence robot that delivered and received items (medication, food, or drink), and also obtained metrics (vital signs) from a simulated patient while the users performed a secondary healthcare-related task (they compiled health records which were displayed to them on the screen and answered related questions). The effect of the two interaction modes on overall performance and user perception was evaluated through a within-participant study design conducted with 50 participants belonging to two different types of populations (with and without a technological background). Efficiency, effectiveness, understanding, satisfaction, and situation awareness were defined as the dependent variables measured both objectively and subjectively. The proactive mode increased user performance, and understanding of the system and reduced the workload compared to the
reactive mode. However, several of the users valued the option of increased user control experienced in the
reactive mode. We, therefore, proposed design suggestions to highlight some of the benefits of factoring the
reactive mode into the design as a hybrid mode.
