Abstract

Methods, apparatuses, and articles for receiving one or more input factors associated with scrolling behavior of a user are described herein. Based on the received one or more input factors, at least one of (1) a tunable scrolling algorithm and (2) one or more non-linear scrolling algorithms of a plurality of non-linear scrolling algorithms may be selected for use in evaluating the scrolling behavior of the user.

Claims

1. A method comprising:

receiving one or more input factors associated with scrolling behavior of a user; and

selecting, based on at least one of the one or more input factors, at least one of (1) a tunable scrolling algorithm and (2) one or more non-linear scrolling algorithms of a plurality of non-linear scrolling algorithms for use in evaluating the scrolling behavior of the user.

2. The method of claim 1, wherein the one or more input factors are selected from the group consisting of a length of a list to be scrolled, a time of a scrolling motion, a direction of the scrolling motion, an input movement speed, a movement direction, and descriptive metadata about contents to be scrolled.

3. The method of claim 2, wherein the descriptive metadata include at least one from the group consisting of a ratchet point of the contents to be scrolled, an entry index of each letter of an alphabet within an alphabetized list to be scrolled, a content/type boundary in the list to be scrolled, and a description of an organization of the contents to be scrolled.

4. The method of claim 1, wherein the tunable scrolling algorithm is capable of adjusting at least one of a scrolling speed, a scrolling sensitivity, and a scrolling time period.

5. The method of claim 1, further comprising evaluating the scrolling behavior of the user, including outputting units of displayable scroll movement based on inputting received units of scroll input to the selected at least one algorithm.

6. The method of claim 1, wherein said receiving the one or more input factors comprises receiving the one or more input factors from one or more user interface-based controls.

7. The method of claim 1, wherein said selecting the at least one algorithm comprises selecting, by a learning algorithm capable of predicting the scrolling behavior of the user, the at least one algorithm.

8. The method of claim 7, further comprising receiving, by the learning algorithm, the one or more input factors as variables capable of modifying the predicted scrolling behavior predicted by the learning algorithm.

9. An apparatus comprising:

a processor; and

a scrolling agent operated by the processor and adapted to

receive one or more input factors associated with scrolling behavior of a user, and

select, based on at least one of the one or more input factors, at least one of (1) a tunable scrolling algorithm and (2) one or more non-linear scrolling algorithms of a plurality of non-linear scrolling algorithms for use in evaluating the scrolling behavior of the user.

10. The apparatus of claim 9, wherein the one or more input factors are selected from the group consisting of a length of a list to be scrolled, a time of a scrolling motion, a direction of the scrolling motion, an input movement speed, a movement direction, and descriptive metadata about contents to be scrolled.

11. The apparatus of claim 9, wherein the tunable scrolling algorithm is capable of adjusting at least one of a scrolling speed, a scrolling sensitivity, and a scrolling time period.

12. The apparatus of claim 9, wherein the scrolling agent is further adapted to evaluate the scrolling behavior of the user, including outputting units of displayable scroll movement based on inputting received units of scroll input to the selected at least one algorithm.

13. The apparatus of claim 9, wherein the one or more input factors are received from one or more user interface-based controls.

14. The apparatus of claim 9, wherein the at least one algorithm is selected by a learning algorithm, the learning algorithm capable of predicting the scrolling behavior of the user.

15. The apparatus of claim 14, wherein the scrolling agent is further adapted to receive, by the learning algorithm, the one or more input factors as variables capable of modifying the predicted scrolling behavior predicted by the learning algorithm.

16. The apparatus of claim 9, wherein the scrolling agent is a user-level component of an operating system of the apparatus, and the apparatus further comprises an adaptive engine of a device driver of the apparatus, the adaptive engine coupled to the scrolling agent, operated by the processor, and adapted to register units of scroll input.

17. The apparatus of claim 9, wherein the scrolling behavior is associated with the user'"'"'s use of one or more of a computer mouse, a keyboard, a scroll wheel, a remote control, a touch pad, and a touch sensitive display.

18. The apparatus of claim 9, wherein the scrolling agent is stored in a selected one of an application specific integrated circuit of the apparatus and a microcontroller of the apparatus, and the application specific integrated circuit/microcontroller is communicatively coupled to one or more device drivers of the apparatus.

19. An article of manufacture comprising:

a storage medium; and

a plurality of programming instructions stored on the storage medium and adapted to program an apparatus to enable the apparatus to

receive one or more input factors associated with scrolling behavior of a user, and

select, based on at least one of the one or more input factors, at least one of (1) a tunable scrolling algorithm and (2) one or more non-linear scrolling algorithms of a plurality of non-linear scrolling algorithms for use in evaluating the scrolling behavior of the user.

20. The article of claim 19, wherein the one or more input factors are selected from the group consisting of a length of a list to be scrolled, a time of a scrolling motion, a direction of the scrolling motion, an input movement speed, a movement direction, and descriptive metadata about contents to be scrolled.

21. The article of claim 19, wherein the tunable scrolling algorithm is capable of adjusting at least one of a scrolling speed, a scrolling sensitivity, and a scrolling time period.

22. The article of claim 19, wherein the programming instructions are further adapted to program the apparatus to evaluate the scrolling behavior of the user, including outputting units of displayable scroll movement based on inputting received units of scroll input to the selected at least one algorithm.
