This study investigates facilitation of a manual target acquisition task by the application of
appropriate force feedback through the control device (eg, mouse, joystick, trackball) …

The poor ergonomics of laparoscopic surgery is a widely recognized source of difficulty for
surgeons, leading to sub-optimal performance on their part and sometimes injury to the …

Laparoscopic surgery requires new methods of technical competency evaluation, as well as
training. The first purpose was to assess the differences in motion characteristics between …

Our current goal is to combine the advantages of medical imaging with force feedback
technology to develop a virtual simulation where the user can touch soft tissue looking for a …

Current robotic systems for minimally invasive surgery do not have effective means of
providing haptics to the surgeon. It was hypothesized that providing an analog for force …

Force feedback is widely assumed to enhance performance in robotic surgery, but its
benefits have not yet been systematically assessed. In this study we examine the effects of …

Force feedback has been suggested to provide a number of benefits to surgery. Few studies,
however, have addressed the benefit of force feedback in the context of the complexities of …

We describe two recent research projects: the Virtual Hand Laboratory, and Remote
Manipulation in Endoscopic Surgery. The Virtual Hand Laboratory (VHL) is a prototype …

Force feedback during teleoperation and in Virtual Reality (VR) environments is becoming
increasingly common. We are interested in understanding the impact of motion on the …

Minimally invasive telerobotic surgical systems enable surgeons to perform complicated
procedures without large incisions. Unfortunately, these systems typically do not provide the …
