The study design is a non-randomized parallel group study in which a group of surgeons (Group A) will make determinations as to the material within each of four visually identical balloons that contain air, water, petroleum jelly or a firm substance similar to the consistency of a non-ripe banana using their hands and eyes while another group of experienced robotic surgeons (Group B) will do so using the da Vinci Xi System (Intuitive Surgical, Sunnyvale, CA）。

在对气球内容的“动手”确定之前，将要求每个参与者首先确定他们是否可以在无需操纵的情况下视觉确定气球内容。 为了进行结果测量，仅考虑两个可能的结果 - 即是否正确排序了4个气球。

调查人员还将为所有参与者记录每个“猜测”，以报告可能发生的任何错误分类趋势。
