Haptic snake: Line-based physical mobile interaction in 3D space

Abstract

This paper introduces a shape-rendering method called haptic snake for interacting with virtual objects in air. Haptic snake is composed of serially linked line segments and is controlled using an active contour model known as a snake algorithm. Through an interface controlled using haptic snake, the user can feel a virtual presence in a 3D space from the changes in its shape and the force exerted from the movement of the interface. For the further work, kinesthetic feedback structure will be developed and justified to develop ungrounded mobile haptic interface.
