Presence: Teleoperators and Virtual Environments

Let us consider the presentation by computers of rich, highly interactive worlds that are inhabited by dynamic and complex characters, and shaped by aesthetically pleasing stories. We shall call this interactive drama, and we believe that it requires ...

A new system combines on-and off-line computer vision with head tracking and image synthesis to form a “virtual batting cage” where a batter swings a real baseball bat at a synthetic recreation of an actual pitch, enabling postswing viewing and ...

We examine the relationship among the different geometries implicit in a stereoscopic virtual environment. In particular, we examine in detail the relationship of retinal disparity, fixation point, binocular visual direction, and screen parallax. We ...

The most common visual feedback technique in teleoperation is in the form of monoscopic video displays. As robotic autonomy increases and the human operator takes on the role of a supervisor, three-dimensional information is effectively presented by ...

In recent years, research in telemanipulation has been concerned primarily with problems related to the control of teleoperators and their man-machine aspects. As the need for extensive teleoperation for the deployment and maintenance of space systems ...

The minimally invasive nature of endoscopic surgery allows operations to be performed through small incisions, producing significantly less damage to good tissue than in conventional open surgery. Patient recovery times are thus greatly reduced. This ...

We track, in real-time, the position and posture of a human body, using a minimal number of six DOF sensors to capture full body standing postures. We use four sensors to create a good approximation of a human operator's position and posture, and map it ...
