Gaze gesture based human robot interaction for laparoscopic surgery.

While minimally invasive surgery offers great benefits in terms of reduced patient trauma, bleeding, as well as faster recovery time, it still presents surgeons with major ergonomic challenges. Laparoscopic surgery requires the surgeon to bimanually control surgical instruments during the operation. A dedicated assistant is thus required to manoeuvre the camera, which is often difficult to synchronise with the surgeon's movements.

Gaze Contingent Cartesian Control of a Robotic Arm for Laparoscopic Surgery.

This paper introduces a gaze contingent controlled robotic arm for laparoscopic surgery, based on gaze gestures. The method offers a natural and seamless communication channel between the surgeon and the robotic laparoscope. It offers several advantages in terms of reducing on-screen clutter and efficiently conveying visual intention.

Enhanced visualisation for minimally invasive surgery.

Purpose: Endoscopes used in minimally invasive surgery provide a limited field of view, thus requiring a high degree of spatial awareness and orientation. Attempts at expanding this small, restricted view with previously observed imagery have been made by researchers and is generally known as image mosaicing or dynamic view expansion. For minimally invasive endoscopy, SLAM-based methods have been shown to have potential values but have yet to address effective visualisation techniques.
