Abstract

An device and method provide logic for processing information. In one implementation, an information processing device includes a detection unit configured to detect a speed of selection of information. The information processing device also includes a generation unit configured to generate a signal specifying a display format, based on the speed of information selection, and a display unit configured to display the selection of information according to the signal.

Claims

1. An information processing device comprising:

a detection unit configured to detect a speed of selection of information;

a generation unit configured to generate a signal specifying a display format, based on the speed of selection; and

a display unit configured to display the selection of information according to the signal,

wherein the generation unit generates a signal configured to change an increment by which a designated area, which indicates a current focus and encompasses at least one informational item of a list of displayed informational items by displaying a focus indicator to encompass the at least one informational item, is scrolled through the list, based on the speed of selection,

wherein the increment is changed by changing a number of the displayed informational items that is included within the designated area and encompassed by the focus indicator, and

wherein the designated area is scrolled through the list by sequentially relocating the designated area by displaying the focus indicator to encompass a subsequent number of the displayed informational items not previously encompassed by the focus indicator.

2. The information processing device of claim 1, wherein the display format comprises a size of the designated area.

3. The information processing device of claim 1, wherein the information processing device further comprises:

a first sensor unit and a second sensor unit, the first sensor unit being configured to detect a first type of user activation, and the second sensor unit being configured to detect a second type of user activation.

4. The information processing device of claim 3, wherein:

the first type of user activation comprises a contact between an operational tool of a user and a surface of the first sensor unit; and

the second type of user activation comprises a contact pressure associated with a contact between the operational tool and a surface of the second sensor unit.

5. The information processing device of claim 4, wherein the operational tool comprises a human appendage.

6. The information processing device of claim 4, wherein the detection unit is further configured to:

receive a signal indicative of the first type of user activation from the first sensor unit; and

identify a contact position associated with the first type of user activation, based on at least the received signal.

7. The information processing device of claim 6, wherein the signal specifying the display format is configured to cause the display unit to designate an initial portion of the displayed information.

8. The information processing device of claim 7, wherein the detection unit is further configured to:

detect a movement of the contact position; and

detect the speed of selection of information based on the detected movement.

9. The information processing device of claim 8, wherein the generation unit is further configured to:

determine that the speed of selection of information fails to exceed a threshold value further comprising an array including a plurality of portions of information arranged in a plurality of rows and columns, and wherein the display unit is configured to;

if the speed of selection is above a threshold, display a selection comprising at least one row of pluralities of portions of information; and

if the speed of selection is not above the threshold, display a selection comprising at least one portion of information.

10. The information processing device of claim 9, wherein the generation unit is further configured to:

generate a successive signal configured to cause the display unit to designate a successive portion of the displayed information, the successive portion having a first unit size.

11. The information processing device of claim 9, wherein the generation unit is further configured to:

generate a successive signal configured to cause the display unit to extend a dimension of the initial portion of the displayed information, the extension being based on the speed of selection of information.

12. The information processing device of claim 9, wherein:

the initial portion of the displayed information comprises an identifier representative of additional information; and

the generation unit is further configured to;

generate a successive signal configured to cause the display unit to replace the displayed identifier with the additional information.

13. The information processing device of claim 9, wherein the generation unit is further configured to:

generate a successive signal configured to cause the display unit to designate a successive portion of the displayed information, the successive portion having a unit size smaller than a corresponding unit size of the initial portion.

14. The information processing device of claim 8, wherein the generation unit is further configured to:

determine that the speed of selection of information exceeds a threshold value.

15. The information processing device of claim 14, wherein the generation unit is further configured to:

generate a successive signal configured to cause the display unit to designate a successive portion of the displayed information, the successive portion having a second unit size.

16. The information processing device of claim 15, wherein:

the display format comprises a multi-dimensional array; and

the successive portion comprises a row or a column of the displayed information.

17. The information processing device of claim 14, wherein the generation unit is further configured to:

generate a successive signal configured to cause the display unit to replace a portion of the displayed information with an identifier representative of the portion of the displayed information.

18. The information processing device of claim 14, wherein the generation unit is further configured to:

generate a successive signal to cause the display unit to designate a successive portion of the displayed information, the successive portion having a unit size larger than a corresponding unit size of the initial portion.

19. The information processing device of claim 8, wherein:

the detection unit is further configured to determine a trajectory of the detected movement; and

the generation unit is further configured to generate a successive signal configured to cause the display unit to display an indication of the trajectory.

20. The information processing device of claim 4, wherein the detection unit is further configured to:

receive, from the second sensor unit, a signal indicative of the contact pressure.

21. The information processing device of claim 20, wherein the generation unit is further configured to:

generate, based on at least the contact pressure, a signal indicative of a user selection of a portion of the displayed information.

22. The information processing device of claim 20, wherein the generation unit is further configured to:

generate a signal configured to cause the display unit to designate a portion of the displayed information, based on the contact pressure.

24. The information processing device of claim 1, wherein the increment by which the designated area is scrolled through the list is increased by increasing a number of informational items of the list being encompassed by the designated area.

23. A computer-implemented method for processing information, the method comprising the steps, performed by a processor, of:

detecting a speed of selection of information;

generating a signal specifying a display format, based on the speed of selection; and

displaying the selection of information according to the signal,

wherein generating a signal comprises generating a signal configured to change an increment by which a designated area, which indicates a current focus and encompasses at least one information item of a list of displayed informational items displaying a focus indicator to encompass the at least one informational item, is scrolled through the list, based on the speed of selection,

wherein the increment is changed by changing a number of the displayed informational items that is included within the designated area and encompassed by the focus indicator, and

wherein the designated area is scrolled through the list by sequentially relocating the designated area by displaying the focus indicator to encompass a subsequent number of the displayed informational items not previously encompassed by the focus indicator.
