Human hand trajectories have been recorded and analyzed in an experimental supervisory control interface for a telerobot manipulator. Using a six degree-of-freedom tracking device to control the gripper of a computer graphics simulation model of the telerobot, human operators were instructed to command the telerobot under a variety of visual conditions.(More)
Robotic surgery has the potential to revolutionize the field of surgery and improve patient safety. However, despite the advantages robotic surgery can offer, there are multiple human factors-related issues that may prevent these systems from realizing their full benefit. This study identified some of the salient human factors issues and considerations that(More)
OBJECTIVE The goals of this study were to understand the reasons underlying the limited use of medical decision-support tools and to explore the potential of a computer-based tutorial to mitigate barriers to use. BACKGROUND Medical decision-support tools such the Acute Cardiac Ischemia Time-Insensitive Predictive Instrument (ACI-TIPI) have demonstrated(More)
The integration of disparate information systems in the operative environment allows access to information that is typically unseen or unused. Through a collaborative effort, a variety of information systems and surgical equipment are being integrated. This provides improved context-sensitive information display and decision support and improved access to(More)
This paper describes new computer-assisted technologies to improve efficiency, efficacy, and safety in robot-assisted minimally invasive surgery (MIS). Although these techniques will be applicable to many arenas of robotically-assisted surgery, these methods are expected to have the biggest impact in soft tissue cardiothoracic surgery. We will focus on the(More)
Capsaicin, main pungent ingredient of hot chilli peppers, has been shown to have anticarcinogenic effect on various cancer cells through multiple mechanisms. In this study, we investigated the apoptotic effect of capsaicin on human pancreatic cancer cells in both in vitro and in vivo systems, as well as the possible mechanisms involved. In vitro, treatment(More)
The integration and presentation of information from a number of disparate sources in the operative environment raises a number of usability and human factors challenges. Through a collaborative effort, a display combining persistent and dynamically switching panes provides a rich source of information to help orient team members, provide indications of(More)
In this presentation we describe the development of a distributed teamwork skills training program for co-located or distributed teams performing complex, highly interdependent tasks that require overlapping expertise and shared knowledge, flexibility, and the capability for rapid organization and deployment to respond quickly to a changing situation. Our(More)
Simulation-based training is a promising instructional approach for training military and civilian medical first responders such as EMTs. There is a need for first responder training in cognitively-based skills such as situation assessment and decision making. We are developing a training program for first responders that uses mannequin-based simulation(More)
