We aim to 1) record the eye hand coordination of novices and experts. Unveiling the gaze strategy and eye-hand coordination of experts to help novices incorporating gaze training into the skills curriculum. 2) use dual eye tracking to study team cooperation in endoscopic therapeutic procedures.
Virtual reality (VR) concepts have been integrated rapidly into rehabilitation programs for helping patients who have had a stroke return to their communities. In this project, we use eye-tracking technology to assess cognition and visual-spatial perceptual abilities in patients who have had a stroke. In collaboration with scientists in the Glenrose Rehabilitation Hospital, the study is conducting in the VR training lab with the CAREN.
We investigate the role of haptic feedback in building motor coordination. We expect that haptic guidance may be used as a tool for learning simple motor tasks and for teaching skills required such as for teleoperation in surgery.
Vigilance is an important skill for surgeons to have. In this project,we used the Tobii Glasses to track the eye motions of novices while performing a cholecystectomy operation using a hybrid pig liver model to see if eyetracking can be used to teach vigilance.
Surgeons rarely work alone in the OR. However, current training configurations often have them practicing their skills individually. Over the summer, we used dual eyetrackers to measure the performance of teams of two of experts and novices.
This is a new addition to our studies. We are currently looking into the feasibility of training surgeons in seeing 3-D images from 2-D inputs for surgery. We are still unsure of the practicality of using a stereographic video input.
This proposed study will look into the effects of laparoscope angles. We seek to insert the camera at such an angle that the overall viewing field will be as if the surgeon was simply looking down onto the surgical site from a natural angle.
At SSRL, we've taken our collective experience to create our own methodology to further deepen our understanding of the human factors of performance and improve the quality of surgical education and patient safety.
We are dedicated to improve surgical education through surgical simulation. We seek to incorporate principles of human factors into the operating theater.
Conducted in cooperation with the department of Computer Sciences of the Simon Frasier University with the lab of Stella Atkins. Geoff Tien and Xianta Jiang are both deeply involved in this project as part of their theses research.
