There is an increasing need for efficient training simulators to teach advanced laparoscopic skills beyond those imparted by a box trainer. In particular, force-based or haptic skills must be… (More)
The novel idea of haptic virtual manipulatives as learning aids for learning disabled K-12 students will be presented. The need for innovative, specialized tools to enhance learning, especially for… (More)
In this work, we describe a novel platform for quantifying surgical suturing skill. Forces and user movements are recorded using sensors during suturing maneuvers performed on a suture patch.… (More)
Laparoscopic surgery demands perceptual-motor skills that are fundamentally different from open surgery, and laparoscopists must be adept at perceiving tissue interaction at the surgical site and… (More)
Humans use their kinesthetic haptic sense for a variety of day-to-day tasks. While manipulating objects using this sensory channel, which corresponds to signals arising in the muscles and joints, it… (More)
In this work, we present four tasks, primarily testing haptic laparoscopic skill that can be simulated in a conventional box trainer. Results from examining expert surgeon and novice performance is… (More)
In this work, we develop an affordable haptic simulator for examining haptic skills required for endovascular Seldinger needle placement.
This work proposes a novel class of metrics for assessing haptic realism in laparoscopic surgical simulators. Results from a proposed perceptual metric are presented and discussed.
In this paper, we present a computer vision algorithm to extract key information pertinent to assessing surgical suturing. This algorithm uses an instrumented platform designed to quantify suturing… (More)
Laparoscopic surgery is a minimally invasive surgical technique with significant potential benefits to the patient, including shorter recovery time, less scarring, and decreased costs. There is a… (More)
