HAPTIC INTERACTION WITH MULTIRESOLUTION IMAGE CURVES

We describe a system for interacting with shapes in two-dimensional im ages with force feedback, using haptic devices. We construct multireso lution models of boundary curves in images, using wavelet multiresolut ion with good approximation properties. The boundary curves are treate d as solid objects that will produce a force when pushed with a mouse- like haptic interface. This interaction force is then to be rendered t hrough a 2-D haptic interface, providing kinesthetic feedback to the u ser. (C) 1997 Elsevier Science Ltd.
