在微创干预中，医生需要与医学图像数据进行交互，而这在双手被占用时是无法完成的。为了解决这一挑战，我们提出了两种交互技术，它们使用凝视和脚作为免提交互的输入方式。为了研究这些技术的可行性，我们创建了一个由移动眼动追踪设备、触觉地板、两台笔记本电脑和血管造影套件的大屏幕组成的设置。我们进行了一项用户研究，以评估如何在不需要手动交互的情况下浏览医学图像。在任务完成时间和主观工作量方面，比较了两种多模式方法以及仅脚交互技术。结果表明，所有方法的性能相当。通过凝视比只用脚更快地完成选择，但是当同时使用凝视和脚时很容易干扰。本文通过提供站立时凝视和足部联合交互的技术和评估结果，为人机交互做出了贡献。我们的方法可以在手术室中实现更有效的计算机交互，从而更有益地利用医疗信息。
During minimally-invasive interventions, physicians need to interact with medical image data, which cannot be done while the hands are occupied. To address this challenge, we propose two interaction techniques which use gaze and foot as input modalities for hands-free interaction. To investigate the feasibility of these techniques, we created a setup consisting of a mobile eye-tracking device, a tactile floor, two laptops, and the large screen of an angiography suite. We conducted a user study to evaluate how to navigate medical images without the need for hand interaction. Both multimodal approaches, as well as a foot-only interaction technique, were compared regarding task completion time and subjective workload. The results revealed comparable performance of all methods. Selection is accomplished faster via gaze than with a foot only approach, but gaze and foot easily interfere when used at the same time. This paper contributes to HCI by providing techniques and evaluation results for combined gaze and foot interaction when standing. Our method may enable more effective computer interactions in the operating room, resulting in a more beneficial use of medical information.
