Description:
FIELD 
       [0001]    The present disclosure generally relates to finger gestures on touch sensitive displays. 
       BACKGROUND 
       [0002]    Touch-based devices have become increasingly important for computer-based devices. For example, smart phones, tablets, and other devices include touch sensitive user interfaces to allow a user to make selections. Although touch-based devices may allow a user to touch a user interface to interact with the device, gestures used to interact with the device may not be intuitive or may be difficult for some users to gesture, making it difficult for the users to interact with the device via touch. 
       SUMMARY 
       [0003]    Methods and apparatus, including computer program products, are provided for finger gestures. 
         [0004]    In one aspect there is provided a method, which may include detecting a first finger gesture proximate to or making contact with a graphical user interface element representative of a first picker wheel presented on a user interface; detecting a second finger gesture proximate to or making contact with the user interface, the second finger gesture detected during a time period comprising a time when the first finger gesture is proximate to or making contact with the first picker wheel; changing, when the second finger gesture is detected, a second picker wheel from an independent mode to a dependent mode; and updating, when in the dependent mode, the second picker wheel based on a selection value made via the first finger gesture at the first picker wheel. Related systems, methods, and articles of manufacture are also described. 
         [0005]    In some implementations, the above-noted aspects may further include additional features described herein including one or more of the following. The first picker wheel may represent a first rotatable wheel including one or more first items. The first picker wheel may be displayed to enable selection of the one or more first items via the first finger gesture. The one or more items may represent one or more days of the month. The second picker wheel may represent a second rotatable wheel including one or more second items. The second picker wheel may be displayed to enable selection of the one or more second items via the second finger gesture. The one or more items may represent one or more months of the year. The independent mode may configure the first picker wheel and the second picker wheels to operate independent, and the dependent mode may causes a selection at the first picker wheel to affect the second picker. The second picker wheel may be changed to an independent mode. The changing to the independent mode may be triggered by at least one of a time out period, a second touch of the second finger gesture, or non-contact by the first finger gesture. 
         [0006]    It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive. Further features and/or variations may be provided in addition to those set forth herein. For example, the implementations described herein may be directed to various combinations and subcombinations of the disclosed features and/or combinations and subcombinations of several further features disclosed below in the detailed description.

       DETAILED DESCRIPTION 
       [0013]    A selection wheel (also referred as a so-called “picker wheel”) is a graphical user interface element representative of a rotatable, spinning wheel including items which can be selected by rotating, via a touch gesture on a touch screen, the wheel. 
         [0014]      FIGS. 1A-1D  depict an example of a graphic user interface  100  including 3 graphical user interface elements representative of picker wheels  110 ,  120 , and  130 . At  FIG. 1A , the first picker wheel  110  corresponds to a day selection, so a single figure gesture  150 , such as a downward swipe or an upward swipe, can be used to rotate/spin or otherwise move the picker wheel until the desired date is selected (which in this example is moving the date from the 31 st  to the 1st). At  FIG. 1B , the finger gesture  150  rotates the second picker wheel  120  to independently select a month (which in this example moves the month from December to January). Then, the finger gesture  150  at  FIG. 1C  moves to the third picker wheel  130  to independently select a year (which in this case moves the year from 2014 to 2015).  FIG. 1D  depicts the resulting settings for the picker wheels  110 - 130 . 
         [0015]    Although  FIG. 1  depicts a downward arrow, the wheels may be moved up or down. 
         [0016]    The example of  FIGS. 1A-D  show that the picker wheels are completely independent, so that although a date increment of only one day is required from Dec. 31, 2014 to Jan. 1, 2015, three independent wheel selections are needed in this example. 
         [0017]    The subject matter described herein relates to configuring the graphical user interface elements so that a detection of a second finger gesture changes the picker wheels from an independent wheel mode (in which each wheel operates without regard to the others as described above with respect to  FIGS. 1A-D ) to a dependent wheel mode (in which a change at a given wheel affects another wheel). 
         [0018]      FIG. 2A  depicts an example of a graphical user interface  200  including three picker wheels  210 ,  220 , and  230  corresponding to date, month, and year picker wheels. 
         [0019]    In the example of  FIG. 2A , a first finger gesture  250  may select one of the picker wheels, such as picker wheel  210  to move the date from “31” to “1.” While the first finger gesture is making contact with the date picker wheel  210 , a second finger wheel makes contact with a portion of user interface  200 . When this is the case, the picker wheels  210 - 230  change modes from an independent mode to a dependent mode. 
         [0020]    While in dependent mode, a selection at the date picker wheel  210  may have an impact on the month picker wheel  220  and/or the year picker wheel  252 . In this example, moving the date at the date picker wheel from the 31 st  to the 1 st  causes the month wheel  220  to scroll to January, which in turn causes the year picker wheel  230  to scroll to 2015 as shown in  FIG. 2B . And, if the picker wheel is moved back to the 31 st , the second picker wheel would move back to December due to the dependent mode operation of the picker wheels. 
         [0021]    In some implementations, the dependent mode remains active so long as the first finger gesture  250  makes contact with the user interface/touch screen presenting the graphical user interface  200  and the second figure gesture  252  makes contact with a portion of the touch screen presenting the graphical user interface  200 . When this is the case, the first finger gesture  250  and/or the second finger gesture  252  not making contact returns the picker wheels to the independent mode. 
         [0022]    In some implementations, the dependent mode is activated by a first touch (for example, a tap) of the second finger  252  while the first finger gesture  250  is making contact with a portion of the touch screen presenting the graphical user interface  200 . When this is the case, a second touch by the second finger gesture  252  while the first finger gesture  250  is making contact with the touch screen may return the picker wheels to an independent mode. 
         [0023]    In some implementations, the dependent mode is activated so long as the second finger gesture  252  makes contact with a specific portion of the user interface  200  while the first finger gesture  250  is also making contact with a touch screen presenting the graphical user interface  200 . For example, the second figure gesture  252  may be required to touch the second picker wheel  220  and/or the third picker wheel  230  (or a designated portion) to change mode into a dependent mode. 
         [0024]    In some implementations, the dependent mode may remain active for a given time period (for example, 5 seconds, 10 seconds, 20 seconds, 30 seconds, 1 minute, 2 minutes, and/or other times as well) after the single tap of the second figure gesture  252 , after which the mode returns to independent mode. 
         [0025]    In some implementations, detecting that the second figure gesture  252  makes contact with the second picker wheel  220  (while the first finger gesture  250  is making contact with a portion associated with the first picker wheel  210 ) makes the picker wheels  210  and  220  dependent but not the third picker wheel  230  unless the second finger gesture  252  also touches for example the third picker wheel  230 . 
         [0026]    Although the previous examples refers to specific types of picker wheels (for example, date, month, and year selection), other types of data may be selected via picker wheels as well. The picker wheels may also be used to dependently pick for example hours, minutes, and seconds (for example, “9”-“30”-“PM”), data and time (for example, “2014-11-11”-“9”-“30”-“PM”), and/or prices (for example, “3 Euro”-“50 cent”). 
         [0027]    Furthermore, although the examples refer to touching a portion of the graphical user interface, touch may refer to touching a touch sensitive display or interface. Moreover, the touch may comprise a proximate touch as some touch sensitive displays can detect a figure touch without actual contact (for example, some capacitive touch displays do not require actual contact with the touch display) on the display. 
         [0028]      FIG. 3  depicts a system  399  for detecting second finger gestures  252  that trigger a change in mode of picker wheels from independent to dependent (and/or vice versa), in accordance with some example implementations. The description of  FIG. 3  also refers to  FIGS. 2A-2B . 
         [0029]    System  300  may include graphical user interface  200 , a processor  397 , and a gesture detector  392 . 
         [0030]    The graphical user interface  300  may include one or more graphical user interface elements, such as picker wheels  210 - 230 . The graphical user interface may be implemented via a display including one or more touch sensitive regions where finger gestures  250  and  252  can be detected. For example, an application, such as a browser and the like, may generate a page, such as HTML, including the picker wheels  210 - 230 , so that the picker wheels can be rotated, selected, and the like via touch (for example, an upward or downward movement or swipe) on the touch sensitive display. 
         [0031]    The processor  397  may include at least one processor circuitry and at least one memory circuitry including computer code, which when executed may provide one or more of the operations disclosed herein. Gesture detector  392  may be implemented using processor  397 , although gesture detector  392  may be implemented using dedicated processor circuitry and/or portions of gesture detector  392  may be incorporated into user interface  200  and/or a touch sensitive display (as well as corresponding touch sensitive display circuitry). 
         [0032]      FIG. 4  depicts a process  400  for detecting a two finger gesture that changes the state of picker wheels from independent to dependent (and/or vice versa), in accordance with some example implementations. The description of  FIG. 4  also refers to  FIGS. 2A-B  and  3 . 
         [0033]    At  410 , a first finger gesture associated with a first picker wheel may be detected. For example, when finger gesture  250  touches (or is proximate to) a touch sensitive display presenting picker wheel  210 , gesture detector  392  may detect this touch event by first finger gesture  250  with respect to picker wheel  210 . 
         [0034]    At  420 , a second finger gesture may be detected while the first finger gesture is making contact with a portion of the graphical user interface. For example, gesture detector  392  may detect second finger gesture  252  while the first finger gesture  250  is making contact with a portion of the graphical user interface. When this is the case, gesture detector  392  may indicate a change in operating mode to a dependent mode (yes at  420 ). In some example implementations, the gesture detector is configured to allow the first finger gesture  250  to momentarily (for example, 2, seconds, 3, seconds, 5 seconds, 10 seconds, 30 seconds, and/or other times as well) not make contact with the touch screen but still register a detection of the second finger gesture  252 . 
         [0035]    If the gesture detector  392  does not detect second finger gesture  252  while the first finger gesture  250  is making contact with a portion of the graphical user interface, the gesture detector  392  may stay in the independent mode (no at  420 ). For example, while the first finger gesture  250  is making contact with the picker wheel  210 , gesture detector  292  may detect second finger gesture  252  making contact with a portion of the touch screen, such as one of the other picker wheels and/or another predetermined portion of the touch screen presenting graphical user interface  200 . As noted above, the gesture detector may, in some implementations, only recognize the second finger gesture  252  when the first finger gesture  250  is actually moving or making contact with the picker wheel  210 . 
         [0036]    At  430 , the picker wheels may operate in independent mode. If the second finger gesture  252  is not detected by for example the gesture detector, the picker wheels may operate independently as noted above with respect to  FIG. 1A-1D , so that a change at a given picker wheel does not affect another picker wheel. 
         [0037]    At  440 , the picker wheel may be configured to operate in a dependent mode. If the second finger gesture is detected by for example the gesture detector, the picker wheels may operate in the dependent mode, so that a change at a given picker wheel does affect another picker wheel as noted for example with respect to  FIGS. 2A-2B . Additionally or alternatively, gesture detector may stay in the dependent mode so long as the first finger gesture  250  is making contact with the user interface/touch screen and the second figure gesture  252  makes contact with the user interface/touch screen as well. In this example, when the first finger gesture  250  and/or the second finger gesture  252  do not make contact with the user interface and/or touch screen, the gesture detector changes picker wheel mode to independent mode. 
         [0038]    When in dependent mode, operation of a second picker wheel may be updated, at  450 , based on the value of the first picker wheel. For example, when the first picker wheel moves via the first finger gesture  250  from the 31 st  to the “1 st ”, the processor and/or gesture detector may update the picker wheels  220  and  230  to dependently move to January and 2015 as described above with respect to  FIG. 2A-2B . 
         [0039]    At  460 , the mode may return to independent mode. The gesture detector and/or processor may trigger a reversion to the independent mode. This reversion may occur after a predetermined timeout period. Alternatively or additionally, a second touch by the second finger gesture  252  may trigger the reversion to the independent mode. Alternatively or additionally, ceasing the touching by the first finger gesture  250  and/or the second finger gesture may trigger the reversion to the independent mode. Alternatively or additionally, the dependent mode may revert to independent mode when a second touch by the second finger gesture  252  is detected while the first finger gesture  250  is making contact with the touch screen. Alternatively or additionally, the dependent mode may remain active for a given time period (for example, 10 seconds, 20 seconds, 1 minute, 2 minutes, and/or other times as well) after a single tap of the second figure gesture  252 , after which the mode returns to independent mode. 
         [0040]    Although the previous example describes a specific use case, other uses cases may be implemented as well. 
         [0041]    Furthermore, although the previous example described the second finger gesture  252  as a touch or tap of the user interface, other gestures may be used as well. For example, other gestures, such as a pinch as well as any other gesture with the second finger may be used as well. Moreover, the touches may be proximate, as noted, to the user interface (so actual contact may not occur).
