Techniques for pointing to locations within a volumetric display
First Claim
1. A volumetric display method, comprising:
- producing a three-dimensional scene in a volumetric display;
producing a three-dimensional pointer for an object in the display by mapping from an input device position into the display independent of scene content and display mechanism,wherein the pointer comprises a ray, anddesignating the object for selection when the ray intersects the object, andwherein the object designated for selection is one of a first object the ray intersects, a last object the ray intersects and one of several objects intersected by the ray as designated by the user.

Abstract
The present invention is a system that creates a volumetric display and a user controllable volumetric pointer within the volumetric display. The user can point by aiming a beam which is vector, planar or tangent based, positioning a device in three-dimensions in association with the display, touching a digitizing surface of the display enclosure or otherwise inputting position coordinates. The cursor can take a number of different forms including a ray, a point, a volume and a plane. The ray can include a ring, a bead, a segmented wand, a cone and a cylinder. The user designates an input position and the system maps the input position to a 3D cursor position within the volumetric display. The system also determines whether any object has been designated by the cursor by determining whether the object is within a region of influence of the cursor. The system also performs any function activated in association with the designation.

16. A volumetric display method, comprising:
-
producing a three-dimensional scene in a volumetric display; and producing a three dimensional pointer in the display, comprising; determining a device position of a input device moving in two dimensions in association with the display; determining a position of a surface cursor on a surface of the display responsive to the device position; and producing a ray in the display projected from the position of the surface cursor and orthogonal to the surface at the position; and selecting a first object intersected by the ray.

17. A volumetric display method, comprising:
-
producing a three-dimensional scene in a volumetric display; and producing a three dimensional pointer in the display, comprising; determining a device position and an orientation vector of an input device positioned in association with the display; determining an intersection point of the vector with the display; determining a length of the pointer from a length setting; and producing a ray in the display projected from the intersection point along the vector to an end point with the end point being located along the vector from the device responsive to the length by mapping from the device position and orientation vector into the display independent of scene content and display mechanism.
