Abstract

A system and method for scrolling through a list of labels where the format in which labels are made manifest can be influenced by the current “search state” of the system. The current “search state” of the system can be influenced by a speed metric. The speed metric can be captured from the interactions between a user and a controller component for a device utilizing the system. In an embodiment of the system, search states are predefined in accordance to speed ranges that are associated with the search states such that a display component can provide a pluralilty of labels that are uniquely displayed over a multi-line display depending on display mode and scrolling speed.

Claims

1. A device, comprising:

a controller for capturing a speed metric, and for enabling a user to scroll through a plurality of labels where a current search state of a plurality of search states is influenced by the speed metric;

a multi-line display utilizing an output component from the controller for manifesting label information associated with at least one of the plurality of labels; and

wherein the manifesting of the label information is influenced by the current state.

2. The device of claim 1, further comprising:

a storage component for storing a plurality of content units associated with at least one label; and

wherein the current search state is identified from the plurality of search states in accordance with the speed metric.

3. The device of claim 2, wherein the plurality of content units are digital music.

4. The device of claim 2, further comprising a plurality of speed ranges such that each search state is associated with at least one speed range in the plurality of speed ranges.

5. The device of claim 4, wherein the plurality of speed ranges are predefined.

6. The device of claim 1, wherein the plurality of search states include a stopped state, a slow state, at least one medium speed state, and a fast state.

7. The device of claim 1, wherein the output component has an output capacity of one multi-line label.

8. The device of claim 1, wherein the controller further provides for capturing a direction metric.

9. The device of claim 1, wherein the plurality of labels includes a currently manifested label, wherein the currently manifested label is made manifest in accordance with a truncation heuristic and a current search state.

10. The device of claim 9, wherein the currently manifested label includes a plurality of characters and the truncation heuristic provides for selectively replacing characters in the currently output label.

11. A media playing device, comprising:

a plurality of search states that include a current state, a first state, at least one second state, and a third state;

a storage component for providing a plurality of media content units and a plurality of labels such that each media content unit is associated with at least one the label of the plurality of labels;

a controller component for capturing both a speed metric and a direction metric, and for scrolls through the plurality of labels, wherein a current state is influenced by the speed metric; and

an output component for displaying over a plurality of lines on a multi-line display at least one label where the display of the label is influenced by the current state such that a current label is configured to be fully displayed in the third state and partially displayed in the first state and in the second state; and

wherein a lesser portion of the current label is displayed in the first state than in the second state.

12. A method for configuring a device, comprising:

identifying a plurality of search states, including at least a first state and a second state;

defining a plurality of speed ranges, including at least a first range and a second range;

associating the first state with the first range and the second state with the second range;

configuring a control component to capture a speed metric such the speed metric identifies a current state from the plurality of states; and

instructing an output component to selectively modify at least one output character displayed over a plurality of lines on a multi-line display depending on the current state.

13. The method of claim 12, wherein the one or more output characters are modified from right to left.

14. The method of claim 12, wherein the output component has an output capacity of one line.

15. The method of claim 12, wherein the device is a music player.

16. The method of claim 12, wherein the output characters are made manifest as a viewable multi-line indicia.

17. The method of claim 12, wherein the one or more output characters are made manifest as audible sounds.

18. The method of claim 12, further comprising creating a plurality of output formats that are associated with a plurality of search states.

19. The method of claim 12, further comprising installing a modifiable user profile.

20. The method of claim 12, further comprising the step of:

loading a plurality of content units into the device where each content unit is associated with a label configured to be made manifest by the output component.

21. A method for scrolling data in an electronic device using a multi-line listbox comprising the steps of:

navigating though an entire multi-line list of fully-expanded text entries when the list box is initially displayed;

navigating though a multi-line list of displayed entries as the listbox is operating in a first mode such that entries are visible above and below the current selection; and

if a first upshift command is issued or if the list is scrolled at a rate faster than a set threshold, upshifting the listbox to a second mode where all the displayed cells of the listbox are replaced with the contents of a second mode list where the contents are aligned such that a currently selected cell displays a unique first word of the previously selected item.

22. A method for scrolling data in an electronic device as in claim 21, further comprising the steps of:

grouping according to their first word all of the alphabetized text entries in the listbox in the second mode;

displaying a list of the first unique words in the listbox such that each entry is followed by a sequence string of characters; and

if a second upshift command is issued or if the list is again scrolled quickly at a rate faster than a set threshold, upshifting the listbox to a third mode where all of the displayed cells of the listbox are re-filled with the contents of the third mode list, that aligned so that the currently selected cell displays the unique first two letters of the previously selected item.

23. A method for scrolling data in an electronic device as in claim 22, further comprising the steps of:

grouping according to their first word all of the alphabetized text entries in the listbox according to their first two letters;

displaying a list of first unique two letters in the listbox such that each entry is followed by a sequence string of characters; and

if the user issues an upshift command or if the list is scrolled quickly at a rate faster than a set threshold, the listbox upshifts to a fourth mode where all of the displayed cells of the listbox are re-followed with the contents of the fourth mode list that are aligned so that the currently selected cell displays the unique first letter of the previously selected item.

24. A method for scrolling data in an electronic device as in claim 23, where the fourth mode includes all the entries in the listbox grouped according to their first letter where only a list of the first unique letters are displayed followed by a sequence of characters.

25. A method for scrolling data in an electronic device as in claim 24, where a particular cell is displayed based on listbox mode or by halting the cursor on the desired entry for a fixed period of time.
