The Globefish is a novel desktop input device for three-dimensional object manipulation and viewpoint navigation. It consists of an elastically suspended 3D trackball, which provides a natural mapping for position-controlled 3D rotations. Rate-controlled 3D translations are performed by pushing the trackball into the appropriate direction. The device is manipulated by the fingertips allowing for precise...
Realistic behavior of control actuators is important for virtual proto-typing applications. We present a systematic approach for modeling such articulated components as described in the European Standard EN 894-3. Control actuators may have several rotational and translational degrees of freedom (DOFs), possibly with discrete lock states. During user interactions, information about the actuators'...
iPhone and iPod Touch are multi-touch handheld devices that provide new possibilities for interaction techniques. We describe iPhone/iPod Touch implementation of a navigation interaction technique originally developed for a larger multi-touch device (i.e. Lemur). The interaction technique implemented on an iPhone/iPod Touch was used for navigation tasks in a CAVE virtual environment. We performed...
In this paper, we describe techniques for supporting a wide-field-of-view multiprojector curved screen display system. Our main contribution is in achieving automatic geometric calibration and efficient rendering for seamless displays, which is effective even in the presence of panoramic surround screens with the multiview calibration method without polygonal representation of the display surface...
