Abstract

Indicators operable to preview or show the position and relative zoom level of a field of view within a virtual space. Virtual space exploration tools typically make use of a field of view for limiting a user'"'"'s view of the virtual space and zooming in on a portion of the virtual space. A spherical indicator is provided to show the current position of the field of view within the virtual space, as well as provide an indication of level of zoom. A local field of view indication is also provided to show the current position of the field of view, as well as provide an indication of level of zoom, with respect to a nearby object within the virtual space. Such indicators may be useful in exploring outer space as well as landscapes and any other spaces.

Claims

1. At least one computer-readable media storing instructions that, when executed by a computer, cause the computer to perform a method for implementing a set of indicators configured for indicating a position and relative zoom level of a field of view in a corresponding spatial environment, the set of indicators comprising:

a spherical indicator rendered on a two-dimensional display, the spherical indicator including;

a circle including an oval between the two horizontal-most points of the circle, the circle representing a sphere of the spherical indicator, the oval representing a celestial equator of the spherical indicator, and

a line between the two vertical-most points of the circle, the line representing a celestial pole of the spherical indicator, and

a center point of the spherical indicator from which a rectangular projection of the field of view is rendered within the spherical indicator, wherein the area of the rectangular projection of the field of view provides an indication of a relative zoom level, and

a North indication associated with the celestial pole, and

a Right Ascension indication associated with the rectangular projection of the field of view, and

a Declination indication associated with the rectangular projection of the field of view; and

a local field of view indicator rendered on the two-dimensional display, the local field of view indicator including;

a rectangular area configured to present a representation of an object of the corresponding spatial environment and to provide a preview of the field of view, and

a representation of the field of view in the form of a rectangle oriented within the rectangular area within the corresponding spatial environment relative to the representation of the object, the representation of the field of view corresponding to the rectangular projection of the field of view, wherein the rectangular area of the representation of the field of view provides an indication of the relative zoom level of the field of view in the corresponding spatial environment, and

a presentation of a name of the object.

2. The at least one computer-readable media of claim 1 wherein the Right Ascension indication is a value presented in an hours, minutes, seconds format.

3. The at least one computer-readable media of claim 1 wherein the Declination indication is a value presented in a degrees, minutes, seconds format.

4. The at least one computer-readable media of claim 1 wherein the corresponding spatial environment is a virtual space representing outer space.

5. The at least one computer-readable media of claim 1 wherein the projection of the field of view is scaled and oriented in the spherical indicator corresponding to the field of view in the corresponding spatial environment.

6. The at least one computer-readable media of claim 1 wherein the representation of the field of view is scaled and oriented in the local field of view indicator relative to the object corresponding to the field of view in the corresponding spatial environment.

7. A method comprising:

implementing, by a computer, a set of indicators configured for indicating a position and relative zoom level of a field of view in a corresponding spatial environment, the set of indicators comprising;

a spherical indicator rendered on a two-dimensional display, the spherical indicator including;

a circle including an oval between the two horizontal-most points of the circle, the circle representing a sphere of the spherical indicator, the oval representing a celestial equator of the spherical indicator, and

a line between the two vertical-most points of the circle, the line representing a celestial pole of the spherical indicator, and

a center point of the spherical indicator from which a rectangular projection of the field of view is rendered within the spherical indicator, wherein the area of the rectangular projection of the field of view provides an indication of a relative zoom level, and

a North indication associated with the celestial pole, and

a Right Ascension indication associated with the rectangular projection of the field of view, and

a Declination indication associated with the rectangular projection of the field of view; and

a local field of view indicator rendered on the two-dimensional display, the local field of view indicator including;

a rectangular area configured to present a representation of an object of the corresponding spatial environment and to provide a preview of the field of view, and

a representation of the field of view in the form of a rectangle oriented within the rectangular area within the corresponding spatial environment relative to the representation of the object, the representation of the field of view corresponding to the rectangular projection of the field of view, wherein the rectangular area of the representation of the field of view provides an indication of the relative zoom level of the field of view in the corresponding spatial environment, and

a presentation of a name of the object.

8. The method of claim 7 wherein the Right Ascension indication is a value presented in an hours, minutes, seconds format.

9. The method of claim 7 wherein the Declination indication is a value presented in a degrees, minutes, seconds format.

10. The method of claim 7 wherein the corresponding spatial environment is a virtual space representing outer space.
