5. The digital picture frame of claim 1, wherein the frame defines left and right edges, the first ring defines a straight boundary and a first arcuate selector element segment extending from a first end of the boundary to a second end of the boundary, the second ring defining a second arcuate selector element segment positioned against the first selector element segment parallel thereto, and the boundary is juxtaposed with and parallel to one of the left or right edges of the frame, whereby a person can conveniently manipulate the selector elements using only a left or right thumb of the person.

6. The digital picture flame of claim l wherein the frame defines left and right edges, each ring defines a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary, and the boundaries of the first and second rings are displayed on a centerline of the digital picture frame that is midway between the left and right edges.

7. The digital picture frame of claim 1, wherein the frame defines left and right edges, each ring defines a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary and midpoints of the selector element segments are substantially tangential to each other at a centerline of the digital picture frame that is midway between the left and right edges.

8. Touch screen controlled by processor to present a user interface (UI) comprising:

at least two groups of selector elements, each group arranged in a respective arc, a first group of selector elements being manipulable to establish an input genre root, a second group of selector elements being manipulable to select an input branching from a genre root selected using an element in the first group, at least one arc being rotatable to reveal previously unpresented selector elements when a person moves a hand along the respective arc.

9. The touch screen of claim 8, wherein the touch screen is bounded by a digital picture frame.

10. The touch screen of claim 8, comprising at least one menu navigation arrow juxtaposed with at least one of the groups and manipulable by a person to navigate through a menu of selections selectable using respective selector elements.

11. The touch screen of claim 9, wherein the frame defines left and right edges, each group is associated with a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary, and the boundaries of the first and second groups are respectively juxtaposed with and parallel to the left and right edges of the frame, whereby a person can conveniently manipulate the selector elements using only respective thumbs of the person.

12. The touch screen of claim 9, wherein the frame defines left and right edges, the first group being associated with a straight boundary and a first arcuate selector element segment extending from a first end of the boundary to a second end of the boundary, the second group being associated with a second arcuate selector element segment positioned against the first selector element segment parallel thereto, and the boundary is juxtaposed with and parallel to one of the left or night edges of the frame, whereby a person can conveniently manipulate the selector elements using only a left or right thumb of the person.

13. The touch screen of claim 9, wherein the frame defines left and right edges, each group is associated with a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary, and the boundaries of the first and second groups are displayed on a centerline of the digital picture frame that is midway between the left and right edges.

14. The touch screen of claim 9, wherein the frame defines left and right edges, each group is associated with a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary, and midpoints of the selector element segments are substantially tangential to each other at a centerline of the digital picture frame that is midway between the left and right edges.

15. Apparatus comprising:

frame;

touch screen bordered by the frame;

computer readable storage medium bearing digital images; and

processor causing at least one image from the medium to be presented on the touch screen, the processor also receiving touch signals from the touch screen, the processor causing the touch screen to present a user interface (UI) comprising.

at least two groups of selector elements, each group arranged in a respective arc, a first group of selector elements being manipulable to establish an input genre root, a second group of selector elements being manipulable to select an input branching from a genre root selected using an element in the first group, at least one arc revealing previously unpresented selector elements when a person moves a hand along the respective arc.

16. The apparatus of claim 15, comprising at least one menu navigation arrow juxtaposed with at least one of the groups and manipulable by a person to navigate through a menu of selections selectable using respective selector elements.

17. The apparatus of claim 15, wherein the frame defines left and right edges, each group is associated with a straight boundary and an arcuate selector element segment extending from a first end of the respective boundary to a second end of the respective boundary; and the boundaries of the first and second groups are respectively juxtaposed with and parallel to the left and right edges of the frame, whereby a person can conveniently manipulate the selector elements using only respective thumbs of the person.
