Medical augmented reality has undergone much development recently. However, there is a lack of studies quantitatively comparing the different display options available. This paper compares the effects of different graphical overlay systems in a simple micromanipulation task with "soft" visual servoing. We compared positioning accuracy in a real-time visually-guided task using Micron, an active handheld tremor-canceling microsurgical instrument, using three different displays: 2D screen, 3D screen, and microscope with monocular image injection. Tested with novices and an experienced vitreoretinal surgeon, display of virtual cues in the microscope via an augmented reality injection system significantly decreased 3D error (p < 0.05) compared to the 2D and 3D monitors when confounding factors such as magnification level were normalized.
医学增强现实技术近年来取得了很大发展。然而，目前缺乏对现有不同显示选项进行定量比较的研究。本文在一个采用“软”视觉伺服的简单显微操作任务中，比较了不同图形叠加系统的效果。我们使用一种有源手持式震颤消除显微手术器械Micron，在一项实时视觉引导任务中，通过三种不同的显示器：二维屏幕、三维屏幕和带有单眼图像注入的显微镜，比较了定位精度。在新手和一位经验丰富的玻璃体视网膜外科医生身上进行测试，当诸如放大倍数等混杂因素归一化后，通过增强现实注入系统在显微镜中显示虚拟线索，与二维和三维显示器相比，显著降低了三维误差（p < 0.05）。
