摘要： 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.
