The advancement of computer information technology would maximize its potential in operating rooms with touchless input devices. A picture archiving and communication system (PACS) was compared with a touchless input device (LMC-GW), relaying to another person to control a mouse through verbal guidance, and directly controlling a mouse.
Participants (n = 34; mean age, 29.6 years) were prospectively enrolled and given nine scenarios to compare the three methods. Each scenario consisted of eight tasks, which required 6 essential functions of PACS. Time elapsed and measurement values were recorded for objective evaluation, while subjective evaluation was conducted with a questionnaire.
In all 8 tasks, manipulation using the mouse took significantly less time than the other methods (all < 0.05). Study selection, panning, zooming, scrolling, distance measuring, and leg length measurement took significantly less time when LMC-GW was used compared to relaying to another person (all < 0.01), whereas there were no significant differences in time required for measuring the angles and windowing. Although the touchless input device provided higher accessibility and lower contamination risk, it was more difficult to handle than the other input methods (all < 0.01).
The touchless input device provided superior or equal performance to the method of verbal instruction in the environment of operating room. Surgeons agreed that the device would be helpful for manipulating PACS in operating rooms with less contamination risk and disturbance of workflow. The touchless input device can be an alternative option for direct manipulation of a mouse in operation rooms in the future.
计算机信息技术的进步将最大限度地发挥其在无接触输入设备手术室中的潜力。与无接触输入设备（LMC-GW）相比，图像存档与通信系统（PACS）通过口头指导将鼠标控制传递给另一个人，并直接控制鼠标。
前瞻性纳入 34 名参与者（平均年龄 29.6 岁），并对三种方法进行了九种场景的比较。每个场景由八个任务组成，需要 PACS 的六个基本功能。记录时间流逝和测量值进行客观评估，同时通过问卷调查进行主观评估。
在所有 8 个任务中，使用鼠标的操作时间明显短于其他方法（均<0.05）。与将鼠标控制传递给另一个人相比，使用 LMC-GW 时，研究选择、平移、缩放、滚动、距离测量和腿长测量所需的时间明显更短（均<0.01），而测量角度和窗口所需的时间则没有明显差异。虽然无接触输入设备提供了更高的可访问性和更低的污染风险，但它比其他输入方法更难操作（均<0.01）。
无接触输入设备在手术室环境中的表现优于或等同于口头指令方法。外科医生认为，该设备有助于在污染风险和工作流程干扰较小的手术室中操作 PACS。无接触输入设备将来可能成为手术室中直接操作鼠标的替代选择。
