In order to provide guidelines for the development and evaluation of advanced laparoscopic instrumentation (including teleoperated devices), we assessed the impact of the ldquo;keyhole rdquo; constraint on surgeons' ability to perform standardized pick-and-place and suturing tasks. We show that avoiding reversed hand and tool motions has a dramatic impact on pick-and-place performance, but adding degrees of freedom (DOFs) yields comparatively little benefit. In suturing, either avoiding the reversed motions or adding DOFs confers substantial benefit, and the benefits are additive
