gaze interaction

Gaze-Based Human-Machine Interaction

The objective of this research is to develop a novel gaze-based human-machine interaction system to intuitively connect elderly or disabled people with assistive devices. The communication will take place through gaze as the control signal. We will focus on basic Activities of Daily Living which enable the individual to live independently.

robotic laparoscopy

Automated Robotic Laparoscopy

The success of laparoscopy as a general surgical technique stems from its ability to create an optical path into a patient's internals with only minor puncturing of the skin. Nonetheless, one problem inherent with known laparoscopic surgery techniques is inconvenient, limited visualization in comparison with traditional open surgery. The surgeon's interventions in laparoscope adjustments are obtrusive barriers for him/her to naturally and intuitively visualize the surgical site. We address these visualization limitations by developing technology to automatically readjust the field of view. The outcomes of this research will allow the surgeon to effectively and naturally visualize the surgical site while freeing both hands to manipulate other instrumentation.

human intention

Intention-Aware Robotics

One of the main challenges in robotics is the lack of a means to effective and natural human-robot interaction. Currently, the user must generate explicit service requests to control the robot's actions, which involves encumbering physical body movements and/or manipulation of an input device. The objective of our research is to develop intention-aware robots which will implicitly understand the user's intention in real time and proactively take the corresponding action at the right time.


Haptics in Laparoscopic Surgery

One disadvantage of laparoscopic surgery is the loss of haptic (force and tactile) information. This deficit is often mentioned in the laparoscopic surgical literature and it is a new trend for the future surgical robotic technology. We are carrying on research on develop a system for measuring and analyzing the motions, as well as forces and torques being applied by the surgeons during laparoscopic procedures. This technology is in great need for multiple application areas, including adding haptic feedback to current laparoscopic robots, providing data for virtual reality simulators for training surgeons, evaluating surgeons' skill level, etc.
