Virtual Bounds: A Teleoperated Mixed Reality
Kevin Ponto, Falko Kuester, Robert Nideffer and Simon Penny

"Over the past 20 years, the lines between the virtual and physical worlds have become increasingly blurred. Computer graphics techniques can now generate images that are nearly photo-realistic, and artificial intelligence has taken great strides in conquering the Turing test. Yet, physical and virtual realities stay juxtaposed when it comes to interaction paradigms. Human-computer-interaction (HCI) is generally a one-way communication in which the physical world tells the virtual world what to do. The virtual world, on the other hand, has no control over the physical world, and may, at best, provide limited force-feedback. Haptics and forcefeedback devices have been developed as a means to address this. Consumer-based versions of these devices usually provide the user with a tactile feedback, most commonly in the form of a rumbling controller. While these systems are evolving, most of the existing feedback devices are intended to simply augment the physical world systems, but are not powerful enough to modify them."
