Abstract

A method for displaying information in a virtual reality environment in which an object that is displayed within a viewport into the virtual reality environment is selected so that the contents of the object can be displayed. The object is opened and the contents of the object are automatically oriented to be perpendicular to a line of sight of the viewport.

Claims

1. A method for displaying information in a virtual reality environment, the method comprising the steps of:

selecting an object in a virtual reality environment, the object being within a viewport into the virtual reality environment and having contents that are to be displayed;

opening the object; and

responsive to opening the object, orienting the contents of the object so that the contents are perpendicular to a line of sight of the viewport, wherein the step of orienting the contents of the object includes the steps of;

comparing the pitch of the viewport to an orientation of a frontal view of the contents of the object,

translating the orientation of the frontal view of the contents of the object to be perpendicular to the pitch of the viewport when there is a difference between the pitch of the viewport and the orientation of the frontal view of the contents of the object, and

displaying the translated orientation of the frontal view of the contents of the object.

2. A program storage device, comprising:

a storage area; and

information stored in the storage area, the information being readable by a machine, and tangibly embodying a program of instructions executable by the machine for performing method steps comprising;

selecting an object in a virtual reality environment, the object being within a viewport into the virtual reality environment and having contents that are to be displayed;

opening the object; and

responsive to opening the object, orienting the contents of the object so that the contents are perpendicular to a line of sight of the viewport, wherein the method step of orienting the contents of the object includes the steps of;

comparing the pitch of the viewport to an orientation of a frontal view of the contents of the object,

translating the orientation of the frontal view of the contents of the object to be perpendicular to the pitch of the viewport when there is a difference between the pitch of the viewport and the orientation of the frontal view of the contents of the object, and

displaying the translated orientation of the frontal view of the contents of the object.

3. The program storage device according to claim 2, wherein the memory includes at least one of a storage device and CD-ROM.

4. A system for displaying information in a virtual reality environment, the system comprising:

means for selecting an object in a virtual reality environment, the object being within a viewport into the virtual reality environment and having contents that are to be displayed;

means for opening the object; and

means, responsive to opening the object, for orienting the contents of the object so that the contents are perpendicular to a line of sight of the viewport, wherein the means for orienting the contents of the object includes;

means for comparing the pitch of the viewport to an orientation of a frontal view of the contents of the object,

means for translating the orientation of the frontal view of the contents of the object to be perpendicular to the pitch of the viewport when there is a difference between the pitch of the viewport and the orientation of the frontal view of the contents of the object, and

means for displaying the translated orientation of the frontal view of the contents of the object.
