This study compares the two-dimensional presentation of stereo-endoscopic video data with three-dimensional presentation using polarization glasses and three-dimensional presentation with an autostereoscopic display. The aim of this study was to evaluate possible advantages of the three display technologies.
Fifty-nine test persons untrained in endoscopy had to complete three endoscopic tasks with different levels of difficulty. Each test involved a new presentation method. Different measurements were noted such as speed of task completion, accuracy of task performance, and quantity of solved tasks. The data collected were statistically evaluated.
Neither sex, handedness, nor level of stereopsis had any statistically significant impact on the test results. The differences between the three presentation methods of stereo-endoscopic pictures were not statistically significant.
Similar results were achieved with all three presentation methods. None of the presentation methods was significantly superior in the values measured. A final assessment of the possibilities of spatial endoscopy should await future technological developments in endoscopic devices (e.g., picture acquisition).
本研究比较了立体内镜视频数据的二维呈现与使用偏光眼镜的三维呈现以及自动立体显示器的三维呈现。本研究的目的是评估这三种显示技术可能存在的优势。
59名未经内镜培训的测试者必须完成三项难度不同的内镜任务。每项测试采用一种新的呈现方法。记录了不同的测量指标，如任务完成速度、任务执行准确性和解决任务的数量。对收集到的数据进行统计学评估。
性别、利手性和立体视觉水平对测试结果均无统计学上的显著影响。立体内镜图像的三种呈现方法之间的差异无统计学意义。
三种呈现方法均取得了相似的结果。在所测量的值方面，没有一种呈现方法具有显著优势。对空间内镜可能性的最终评估应等待内镜设备未来的技术发展（如图像采集）。
