The requirements for tracking in augmented reality environments are stringent because of the need to register real and computer-generated virtual objects. Driven by the need to track real objects within these environments, we propose two algorithms to distribute markers on complex rigid objects. The proposed algorithms employ an optimization technique with(More)
A framework for real-time visualization of a tumor-influenced lung dynamics is presented in this paper. This framework potentially allows clinical technicians to visualize in 3D the morphological changes of lungs under different breathing conditions. Consequently, this technique may provide a sensitive and accurate assessment tool for pre-operative and(More)
Visualizing information in three dimensions provides an increased understanding of the data presented. Furthermore, the ability to manipulate or interact with data visualized in three dimensions is superior. Within the medical community, augmented reality is being used for interactive, three-dimensional (3D) visualization. This type of visualization, which(More)
1. Introduction In this demonstration, we introduce members of the research community to the possibility of visualization with the ARC Display. The ARC Display represents a significant advancement towards our vision of wearable displays for multi-modal augmented reality systems [1]. The ARC Display currently provides a unique theatre for stereoscopic(More)
Current military forces increasingly rely upon unmanned systems. Training mixed teams of soldiers and robotic agents can be accomplished using specialized virtual environments or fabricated real-life structures. However, there are still gaps in the technology and methodologies needed to support human-robot teams. In addition, the environments presently used(More)
e define a virtual environment as a set of surroundings that appear to a user through computer-generated sensory stimuli. The level of immersion—or sense of being in another world—that a user experiences within a VE relates to how much stimuli the computer delivers to the user. Thus, you can classify VEs along a virtuality continuum, illustrated in Figure(More)
