Implementing perception-action coupling for laparoscopy
This chapter discusses implementation aiming at restoring perception-action coupling with respect to visual information by linking the point of observation or the point of illumination directly to the head movements of the surgeon. This restores the perception-action coupling and allows the surgeon to obtain spatial information through exploration. However, two problems arise. First, manipulation and making explorative movements conflict with each other. Although observation tasks do invite the observer to move, manipulation tasks, for example, putting a wire through the eye of a needle, do not. Second, there are technical constraints such as size and shape; for example, the mechanism must be small enough to be used during laparoscopy, or the mechanism may not harm the patient. Implementation aimed at restoring perception-action coupling during laparoscopy is explored within the framework of the ecological approach to visual perception as described by Gibson (1979
Two-handed gesture-based car styling in a virtual environment
Virtual reality offers stylists the possibility to immediately sketch and model in 3D, combining the sketching and modelling stages of the design process. In this paper we describe MOVE ON, a new two-handed gesture-based Computer Aided Conceptual Design application for use in a virtual environment. The use of two-handed form-descriptive gestures to sketch and deform automobiles three dimensionally, gives the stylist an intuitive and natural way of styling. With MOVE ON, the stylist is offered a computer supported approach that respects his creative, expressive and skilful profession, by giving him expressive freedom, personal style and a method that fits his motor skills. The virtual environment stimulates direct interaction with the designs, tools and environment, thus creating an idea generation, presentation and evaluation tool. We are currently experimentally testing the feasibility of MOVE ON for conceptual design
