Abstract

In a system and a method, a selection of an input data field is detected. In response to the selection of the input data field, a user interface having an inner concentric circle and an outer concentric circle is generated. A contact point corresponding to a location of a touch gesture submitted via a touch-enabled input device within one of the inner concentric circle and the outer concentric circle is detected. An angular velocity of circular movement from the contact point around one of the concentric circles is measured. An input data value is adjusted at a granularity based on the contact point and at a rate based on the measured angular velocity of circular movement.

Claims

1. A system, comprising:

a processor-implemented user interface (UI) generator module configured to generate a touch-enabled UI in response to a selection of an input data field, the touch-enabled UI comprising an inner concentric circle UI and an outer concentric circle UI;

a processor-implemented movement detection module configured to;

detect a user input contact point within at least one of the inner concentric circle UI and the outer concentric circle UI; and

measure an angular velocity of circular movement from the user input contact point around the at least one of the inner concentric circle UI and the outer concentric circle UI; and

a processor-implemented data input module configured to;

adjust an input data value at a granularity based on the user input contact point and at a rate based on the measured angular velocity; and

provide the adjusted input data value for display.

2. The system of claim 1, further comprising a processor-implemented input device interface module configured to receive touch gestures from a touch-enabled input device and to translate the received touch gestures into commands recognized by the processor-implemented movement detection module.

3. The system of claim 1, wherein the input data field is at least one of a time field and a date field.

4. The system of claim 1, wherein the processor-implemented movement detection module is further configured to detect a touch command indicating completion of selection of the input data value.

5. The system of claim 3, wherein the touch command is at least one of a tap on a touch-enabled display screen, a horizontal movement, and a vertical movement.

6. The system of claim 1, wherein the processor-implemented UI generator module is further configured to enlarge the touch-enabled UI in response to a touch command to zoom in on the touch-enabled UI.

7. The system of claim 1, wherein the inner concentric circle UI adjusts the input data value at a first granularity and the outer concentric circle UI adjusts the input data value at a second granularity.

8. A computer-implemented method, comprising:

detecting selection of an input data field by a first touch gesture submitted via a touch-enabled input device;

generating a circular user interface (UI) in response to the selection of the input data field, the circular UI comprising an inner concentric circle UI and an outer concentric circle UI;

detecting a user input contact point within at least one of the inner concentric circle UI and the outer concentric circle UI, the user input contact point corresponding to a location of the first touch gesture submitted via the touch-enabled input device;

measuring an angular velocity of circular motion from the user input contact point around the at least one of the inner concentric circle UI and the outer concentric circle UI; and

adjusting a displayed input data value at a granularity based on the user input contact point and at a rate based on the angular velocity.

9. The computer-implemented method of claim 8, further comprising detecting a second touch gesture submitted via the touch-enabled input device, the second touch gesture indicating completion of selection of the displayed input data value.

10. The computer-implemented method of claim 8, further comprising enlarging the circular UI in response to receiving a second touch gesture.

11. The computer-implemented method of claim 8, wherein the input data field is at least one of a date field and a time field.

12. The computer-implemented method of claim 8, wherein the inner concentric circle adjusts the displayed input data value at a first granularity and the outer concentric circle adjusts the displayed input data value at a second granularity.

13. The computer-implemented method of claim 9, wherein the second touch gesture is at least one of a tap gesture on the touch-enabled input device, a pressure gesture applied to the touch-enabled input device, a horizontal movement, and a vertical movement.

14. A non-transitory machine-readable storage medium storing a set of instructions that, when executed by a processor, causes the processor to perform operations, comprising:

detecting selection of an input data field by a first touch gesture submitted via a touch-enabled input device;

generating a user interface (UI) in response to the selection of the input data field, the UI comprising an inner concentric circle UI and an outer concentric circle UI;

detecting a user input contact point within at least one of the inner concentric circle UI and the outer concentric circle UI, the user input contact point corresponding to a location of the first touch gesture submitted via the touch-enabled input device;

measuring an angular velocity of circular motion from the user input contact point around the at least one of the inner concentric circle UI and the outer concentric circle UI; and

adjusting a displayed input data value at a granularity based on the user input contact point and at a rate based on the angular velocity.

15. The non-transitory machine-readable storage medium of claim 14, further comprising detecting a second touch gesture submitted via the touch-enabled input device, the second touch gesture indicating completion of selection of the displayed input data value.

16. The non-transitory machine-readable storage medium of claim 14, further comprising enlarging the generated UI in response to receiving a second touch gesture.

17. The non-transitory machine-readable storage medium of claim 14, wherein the input data field is at least one of a date field and a time field.

18. The non-transitory machine-readable storage medium of claim 14, wherein the inner concentric circle UI adjusts the displayed input data value at a first granularity and the outer concentric circle UI adjusts the displayed input data value at a second granularity.

19. The non-transitory machine-readable storage medium of claim 15, wherein the second touch gesture is at least one of a tap gesture on the touch-enabled input device, a pressure gesture applied to the touch-enabled input device, a horizontal movement, and a vertical movement.
