Abstract

A system and method for scrolling through a list uses control and display algorithms for scrolling through a long list of text strings. The control algorithm interfaces to the user via a rate-based scheme to switch the display through various levels of abstraction where higher levels of abstraction are displayed “in-situ” on the single-line display. These higher levels of abstraction display as starting characters or words that are common to a group of entries in the alphabetized list. Multiple levels of abstraction are supported, where lower levels of abstraction are displayed as longer strings of characters, representing smaller groups of entries in the given list of text strings. Higher levels of abstraction are displayed as shorter character strings. The rate of user movement is detected for the display to change to a previous or next item in the list if below a predetermined threshold while increasing the abstraction level if the user rapidly selects different options.

Claims

1. A method for scrolling through a list in an electronic device comprising the steps of:

providing a display having a single line for displaying alphanumeric text for one entry of an alphabetized list and a terminating character string, said alphanumeric text including an alphanumeric text string having alphanumeric text characters and said terminating character string including one or more terminating characters, wherein said one or more terminating characters includes using a same terminating-type character;

replacing the display with a alphanumeric text phrase representing a cluster of items in said alphabetized list when a user requests a higher level of abstraction such that the alphanumeric text phase consists of at least one alphanumeric text character configured to form a common starting phrase of the group of alphabetized entries of which a currently displayed alphanumeric entry is a member; and

navigating though multiple levels of abstraction using a control algorithm such that attaining each higher level of abstraction displays a successively shorter alphanumeric text string in said currently displayed entry while further displaying a successively larger terminating character string containing the same terminating-type character in said currently displayed entry,

wherein when at least an alphanumeric text character in the alphanumeric text string is removed from the display the same terminating-type character is added in said terminating character string to replace the removed alphanumeric text character.

2. The method for scrolling through the list as in claim 1, wherein the terminating-type character is represented by a symbol being one of “

*” and

“

-” and

“

.”

.

3. The method for scrolling through the list as in claim 1, further including the step of:

navigating though the multiple levels of abstraction using the control algorithm such that each higher level of abstraction displays shorter text strings which represent a larger number of individual entries in the alphabetized list.

9. The method for scrolling through the list as in claim 1, wherein with removal of each alphanumeric text character in said alphanumeric text string being displayed on the display represents to the user a larger number of individual entries in one of the cluster of items and the alphabetized list being available for access by the user.

4. A method for scrolling through a list in an electronic device including the steps of:

providing a display having a single line for displaying alphanumeric text for one entry of an alphabetized list and a terminating character string, said alphanumeric text including an alphanumeric text string having alphanumeric text characters and said terminating character string including one or more terminating characters, wherein said one or more terminating characters includes using a same terminating-type character;

replacing the display with an alphanumeric text phrase representing a cluster of items in said alphabetized list when a user requests a higher level of abstraction such that said alphanumeric text phase consists of at least one character that forms a common starting phrase of a group of alphabetized entries of which a currently displayed alphanumeric entry is a member;

utilizing a rate-based control algorithm such that if the user advances through said the alphabetized list at a rate faster than a predetermined value the level of abstraction is increased by one from the currently displayed entry wherein the increased level of abstraction displays a successively shorter alphanumeric text string in said currently displayed entry while further displaying a successively larger terminating character string containing the same terminating-type character in said currently displayed entry, and if the user advances through said alphabetized list at a rate slower than the predetermined value the display is changed to one of a previous and next item from the currently displayed entry in the alphabetized list; and

updating the display after the step of utilizing the rate-based control algorithm using a common starting phrase of a group of alphabetized entries of which a currently displayed entry is a member;

wherein when at least an alphanumeric text character in the alphanumeric text string is removed from the display the same terminating-type character is added in said terminating character string to replace the removed alphanumeric text character.

5. The method for scrolling through the list as in claim 4, wherein the electronic device comprises a user profile, and the predetermined values are input by the user in to the user profile.

6. The method for scrolling through the list in an electronic device as in claim 4, further comprising the step of:

allowing the user to manually select one of a higher and a lower level of abstraction on the currently displayed entry by using a paddle lever associated with the electronic device.

7. The method for scrolling through the list as in claim 4, wherein the terminating-type character is represented by a symbol being one of “

*” and

“

-” and

“

.”

.

8. A method for scrolling through a list as in claim 4, further including the step of:

navigating though multiple levels of abstraction using a control algorithm such that each higher level of abstraction displays shorter text strings which represent a larger number of individual entries in the alphabetized list.

10. The method for scrolling through the list as in claim 4, further including the step of,

reducing the level of abstraction with the device of the currently displayed entry to a next lower abstraction level if the user does not scroll the alphabetized list for a predetermined time period.

11. The method for scrolling through the list as in claim 4, further including the step of,

reducing the level of abstraction with the device of the currently displayed entry to a lowest level of abstraction if the user does not scroll the alphabetized list for at least one predetermined time period, whereby the lowest level of abstraction includes the currently displayed entry having a full text string of characters with no terminating string character.

12. The method for scrolling through the list as in claim 4, wherein the electronic device is configured to audibly reproduce the currently displayed entry to the user.

13. The method for scrolling through the list as in claim 4, wherein the predetermined value includes a plurality of speed ranges associated with a plurality of search states, and the level of abstraction is determined by a time rate of movement at which the user scrolls the alphabetized list, and the time rate of movement correlates with a speed range in the plurality of speed ranges associated with each search state.

14. The method for scrolling through the list as in claim 13, wherein the plurality of search states comprises a fast, a medium, a slow, and a stopped search state, and the plurality of speed ranges associated with the plurality of search states correspond to an amount of time for the user to move between clicks generated by a selector element in electrical connection with the electronic device in combination with a scrolling truncation heuristic to determine a selection of the search state, and time values in a speed range for the slow search state are generally less than time values in a speed range for the stopped search state and time values in a speed range for the medium search state are generally less than the time values in the speed range in the slow search state and time values in a speed range for the fast search state are generally less than the time values in the speed range for the medium search state.
