| Indicates location, without a jump to feature, or a pagination control per se. Dot indicators are this, for example. Note comparison to Scroll and how scrollbars and thumbnails are special cases, considered in detail there, which see. NOTE in the pattern that this is not usually an access method, just an indicator that other patterns are used to get access, like Home page Slideshow style. Compare Hero200 and Galaxy. Sliding bar vs. transitioning dot. Do not just indicate, but actually show movement, to make it clear what is being shown off. Indicator can disappear when not actively moving, but can be confusing, so often should always be there... |

Problem
Location within a series of screens with alternate views, or which continue the display of a set of content, should be clearly communicated.
Solution
When several screens of similar or continuous information are presented with an organic access method, an indicator is usually required so the user understands their position within the system. Two very common uses for this widget are the Slideshow and Film Strip] patterns. These each have the inter-frame interaction integrated with the basic pattern.
This overlaps heavily with the Pagination widget, to the degree where it may be unclear which is being applied. The key determining factor is if the indicator is integral with the method of changing pages.
Variations
Location Within widgets are used to convey the specific context of a page within a series. The method used depends on the amount and type of information being presented. There are two basic types.
Text widgets list the current page, of a set of pages. "1 of 16," for example. This is often encountered in slideshows, or other contexts where much other meta-data is often displayed. These are suitable for any number of screens; numbers are very space-efficient ways of displaying the information.

Interaction Details
There are no direct interaction details with the indicate-only Location Within pattern.
Presentation Details
