Abstract
A head mounted device provides an immersive virtual or augmented reality experience for viewing data and enabling collaboration among multiple users. Rendering images in a virtual or augmented reality system may include capturing an image and spatial data with a body mounted camera and sensor array, receiving an input indicating a first anchor surface, calculating parameters with respect to the body mounted camera and displaying a virtual object such that the virtual object appears anchored to the selected first anchor surface. Further operations may include receiving a second input indicating a second anchor surface within the captured image that is different from the first anchor surface, calculating parameters with respect to the second anchor surface and displaying the virtual object such that the virtual object appears anchored to the selected second anchor surface and moved from the first anchor surface.
