Application of Augmented and Virtual Reality Technologies in Medicine

Background and Aim: Virtual Reality and Augmented Reality are immersive technologies that integrate virtual and real-world elements. These technologies have been used to help and improve human capabilities in many fields. Virtual and augmented systems are used in various medical situations. They are effective options in most stages of patient treatment and performing medical procedures. Therefo...

Virtual Reality Telerobotic System

This paper describes a telerobotic system operated through a virtual reality (VR) interface. A least squares method is used to find the transformation mapping, from the virtual to real environments. Results revealed an average transformation error of 3mm. The system was tested for the task of planning minimum time shaking trajectories to discharge the contents of a suspicious package onto a wor...

A Three Dimensional Image Cache for Virtual Reality

Despite recent advances in rendering hardware, large and complex virtual environments cannot be displayed with a sufficiently high frame rate, because of limitations in the available rendering performance. This paper presents a new approach of software accelerated rendering which draws from the concepts of impostors, hierarchical scene subdivision and levels of detail. So far software optimizat...
