FIELD OF THE INVENTION
This invention relates to methods of operation and computer program products for touch sensitive mobile devices.
BACKGROUND OF THE INVENTION
Touch sensitive mobile devices employ a touch sensitive screen for simultaneously depicting content and enabling a user to draw discrete navigation gestures. Mobile device operating systems typically display a lock screen requiring a user to draw a discrete unlock gesture to confirm that he has deliberately activated his mobile device. Mobile device operating systems also typically display a home screen for depicting parent mobile device destination icons for enabling a user to launch different mobile device applications including inter alia a phone application for placing a call, one or more messaging applications for sending a message, one or more browsing applications for browsing the internet, and the like. More recent mobile device operating systems combine the functionalities of a lock screen and a home screen into a single combined lock/home screen such that a single navigation gesture activates a mobile device and launches a mobile device application.
Many users have many tens of pre-installed or self-installed mobile device applications and a hundred or more contacts. The present invention affords a more convenient user experience to select and launch a mobile device destination.
Terminology
The following terms are employed in the description and the claims:
Mobile device: Mobile devices in the context of the present invention include inter alia smart phones, tablets, and the like.
User contact: User contact on a touch sensitive screen of a touch sensitive mobile device in the context of the present invention includes inter alia a user placing his finger to physically contact a touch sensitive screen to draw a discrete navigation gesture, using a stylus or similar pointed instrument to draw a discrete navigation gesture, and the like.
Discrete navigation gesture: Single continuous user contact with a touch sensitive screen from an initial user contact thereon to a final user release therefrom. User release from a touch sensitive screen can be intentional to indicate termination of a single discrete navigation gesture or inadvertent, for example, because a user was distracted by someone calling his name, and the like. Discrete navigation gestures include so-called single finger movement actions such as taps, swipes, pinching, complete circles, and the like. Swipes can be straight or curved. Discrete navigation gestures also include so-called multiple finger movement actions consisting of two or more continuous finger movements. The continuous finger movements can include straight finger movements angled to each other, curved finger movements, and a combination of straight and curved finger movements. Adjacent straight finger movements can subtend an acute angle, a right angle to form a draw a letter L or an obtuse angle. A user may pause a single discrete navigation gesture at a particular screen location and continue with the same single discrete navigation gesture.
Types of Mobile Device Destinations
The following types of mobile device destinations are described in the description and the claims:
Mobile device destination: A mobile device destination can include inter alia a mobile device application, a website/URL, a contact person details, a log entry, for example, a missed call, a multimedia item, and the like.
Parent mobile device destination: A mobile device destination which can be selected by a unique mobile device destination icon depicted on a home screen and/or a lock screen. Parent mobile device destinations can have one of three destination functionalities described hereinbelow including optionally pointing to one or more child mobile device destinations. Parent mobile device destinations include inter alia messaging options, a library of applications, favorite websites, favorite contacts, and the like.
Child mobile device destination: A mobile device destination which can be selected and launched from a unique child mobile device destination icon. A child mobile device destination can be typically arrived at from one or more parent mobile device destinations. A child mobile device destination can optionally point to its own one or more child mobile device destinations. Child mobile device destinations can typically number from a few child mobile device destinations to hundreds of child mobile device destinations. The lists of child mobile device destinations can be sorted by different parameters depending on their nature. Typical parameters include inter alia date and time, alphabetical, frequency, and the like.
Library of mobile device destinations: A multitude of similar mobile device destinations of the same type, for example, applications, websites, contact persons, and the like. Libraries of mobile device destinations are typically too long to be depicted on a single display screen.
Mobile device destination set: A multitude of mobile device destinations including at least one parent mobile device destination and at least one child mobile device destination.
Types of Display Screens
The following types of display screens are described in the description and the claims:
Default display screen: A display screen displayed on a touch sensitive screen on detection of user release from the touch sensitive screen not at a display screen icon. The display screen icon can be a parent mobile device destination icon, a child mobile device destination icon, and the like. The default display screen can be defined to be a mobile device's lock screen, its home screen, its combined lock/home screen, and the like. A mobile device can be programmed to have repeatedly display the same default display screen. Alternatively, a mobile device can be programmed to display different default display screens under different circumstances.
Destination display screen: A display screen pursuant to the selection and launching of a mobile device destination.
Home screen: A display screen displaying at least one parent or child mobile device destination icon.
Intermediate navigation display screen: A display screen displayed during the course of a single discrete navigation gesture. During the course of a single discrete navigation gesture, a mobile device can display one or more intermediate navigation display screens.
Lock screen: Lock screens in the context of the present invention are display screens displayed on a touch sensitive screen when a mobile device is in a so-called lock state and the mobile device is operative in a limited way without a user executing a discrete unlock gesture to unlock the mobile device. Lock screens may include, for example, a 3 by 3 grid of points requiring a user to draw a security pattern connecting two or more points.
SUMMARY OF THE INVENTION
Generally speaking, the present invention is directed towards methods and computer program products for touch sensitive mobile devices including a mobile device operating system operative with a touch sensitive screen for displaying display screens, and detecting user contact thereon and user release therefrom. In greater particularity, the present invention is directed towards methods of operation of touch sensitive mobile devices for enabling a user to employ a single discrete navigation gesture to select and launch a mobile device destination. The single discrete navigation gestures of the present invention can start with an unlock gesture before proceeding to select and launch a mobile device destination.
In accordance with a first aspect of the present invention, there is provided a method of operation for enabling a user to employ a single discrete navigation gesture to select and launch a child mobile device destination. In greater particularity, the method of operation includes the following steps:

    (a) on detecting user contact on the touch sensitive screen, displaying an intermediate navigation display screen depicting at least one parent mobile device destination icon;
    (b) on detecting continuous user contact on the touch sensitive screen displaying the step (a)'s intermediate navigation display screen at a parent mobile device destination icon of a user selected parent mobile destination, displaying another intermediate navigation display screen depicting at least one child mobile device destination icon associated with the user selected parent mobile device destination;
    (c) on detecting user release from the touch sensitive screen displaying step (b)'s intermediate navigation display screen, thereby terminating a user's single discrete navigation gesture,


(c1) at a child mobile device destination icon of a user selected child mobile device destination, launching the child mobile device destination, and
(c2) neither at a parent mobile device destination icon nor at a child mobile device destination icon, not launching a child mobile device destination.
In accordance with a second aspect of the present invention, there is provided a method of operation for enabling a user to employ a single discrete navigation gesture to select and launch a user selected mobile device destination from a library of mobile device destinations. This second aspect of the present invention is particularly suitable for gesture navigation through long lists of similar mobile device destination icons which are too long to be depicted simultaneously on a display screen.
This second aspect of the present invention can be implemented by two alternative embodiments as follows: In one embodiment, a group of at least one mobile device destination icon is depicted on a display screen and a user is required to draw an additional segment of his single discrete navigation gesture to change one or more mobile device destination icons of the group of at least one mobile device destination icon. Additional consecutive segments can trace the same forward and backward path on a touch sensitive screen, a closed path, for example, a square, or an open path.
In the alternative embodiment, a group of at least one mobile device destination icon is depicted on a display screen, and a user maintains his finger position at a pre-determined screen location for automatically changing one or more mobile device destination icons of the group of at least one mobile device destination. The alternative embodiment can be programmed with two alternative mobile device destination selection schemes as follows:
First, a user is required to navigate his finger to a mobile device destination icon of a user selected mobile device destination for launching the mobile device destination on user release from the touch sensitive screen thereat. User release not at a mobile device destination icon, does not launch a mobile device destination.
And second, a display screen depicts a destination zone for indicating a mobile device destination icon of an instantaneously displayed group of at least one mobile device destination icon and a cancel navigation icon for not launching a mobile device destination on detection of user release from the touch sensitive screen thereat. The destination zone is necessarily readily visually distinguishable from the remaining display screen so that a user can clearly recognize which mobile device destination icon is presently being indicated. Such visual distinction can be achieved by a background color, a flashing display screen zone, and the like. Accordingly, detection of user release from the touch sensitive screen at any screen location except at the cancel navigation icon, launches the mobile device destination indicated by the destination zone.
In greater particularity, the former embodiment of the method of operation includes the following steps:

    (a) displaying a display screen depicting a group of at least one mobile device destination icon of the library of mobile device destination icons, and a forward navigation icon for navigating forward through the library of mobile device destination icons;
    (b) on detecting continuous user contact on the touch sensitive screen at the forward navigation icon, refreshing the display screen to depict the group of at least one mobile device destination icon with at least one new mobile device destination icon and another forward navigation icon offset from the previously depicted forward navigation icon;
    (c) on detecting continuous user contact at the touch sensitive screen at step (b)'s another forward navigation icon, repeating step (b); and
    (d) on detecting user release from the touch sensitive screen, thereby terminating a user's single discrete navigation gesture,


(d1) at a mobile device destination icon of a user selected mobile device destination, launching the user selected mobile device destination, and
(d2) not at a mobile device destination icon, not launching a mobile device destination.
And in greater particularity, the latter embodiment of the method of operation includes the following steps:

    (a) displaying a display screen depicting a group of at least one mobile device destination icon of the library of mobile device destination icons, and a navigation icon for navigating through the library of mobile device destination icons;
    (b) on detecting continuous user contact stationary at the navigation icon, proceeding to periodically refresh the display screen with at least one new mobile device destination icon; and
    (c) in accordance with one of two alternative mobile device destination selection schemes:


(c1) on detecting user release from the touch sensitive screen, thereby terminating a user's single discrete navigation gesture, at a mobile device destination icon of a user selected mobile device destination, launching the mobile device destination, and on detecting user release from the touch sensitive screen not at a mobile device destination icon, not launching a mobile device destination, and
(c2) displaying a destination zone for indicating a mobile device destination icon of an instantaneously displayed group of at least one mobile device destination icon and a cancel navigation icon for not launching a mobile device destination on detection of user release from the touch sensitive screen thereat, whereupon, on detecting user release from the touch sensitive screen at any screen location except at the cancel navigation icon, launching the mobile device destination associated with the mobile device destination icon indicated by the destination zone.
This second aspect of the present invention can be optionally implemented in combination with the first aspect of the present invention. Accordingly, a user draws a single discrete navigation gesture to initially select a parent mobile device destination and subsequently proceeds to select a child mobile device destination associated with the user selected parent mobile device destination without user release from the touch sensitive screen. Implementation of both the first and second aspects of the present invention affords a user the ability to use a single discrete navigation gesture to select and launch any mobile device destination from a lock screen.

Possibly one more additional discrete navigation gesture is required to arrive at the FIG. 7 application library display screen 134 via the FIG. 6 application library display screen 133.
Single Discrete Navigation Gesture to Select and Launch a User Selected Child Mobile Device Destination from a Mobile Device Destination Set
For better understanding the first aspect of the present invention, parent mobile device destinations can be classified as having one of three destination functionalities as follows:
A first destination functionality whereupon, on detection of user contact at a parent mobile device destination icon, the mobile device 100 displays an intermediate navigation display screen displaying child mobile device destination icon(s) of at least one child mobile device destination pointed to by the user selected parent mobile device destination. Detection of user release from the touch sensitive screen 102 at one of the child mobile device destination icons launches the child mobile device destination associated therewith. Detection of user release at any other screen location on the touch sensitive screen 102 including at a parent mobile device destination icon does not launch a child mobile device destination. Such user release typically leads to the mobile device 100 displaying either the same display screen displayed immediately prior to user release or a default display screen.
A second destination functionality similar to the first destination functionality and differing therefrom insofar that user release from the touch sensitive screen 102 at a parent mobile device destination icon of a user selected parent mobile device destination launches the parent mobile device destination.
And a third destination functionality whereupon, on detection of user release from the touch sensitive screen 102 at a parent mobile device destination icon of a user selected parent mobile device destination, the mobile device 100 launches the parent mobile device destination. Such parent mobile device destinations do not have one or more child mobile device destinations. Typical third destination functionality types include inter alia launching a mobile device capability only, for example, operating a built-in camera. Detection of user release from the touch sensitive screen 102 at any other screen location on the touch sensitive screen 102 does not launch a parent mobile device destination. Such user release typically leads to the mobile device 100 displaying either the same display screen displayed immediately prior to user release or a default display screen.
In the following description, the messaging options destination MES is deemed to have first destination functionality, the phone application destination PHO is deemed to have second destination functionality, and the built-in camera destination CAM is deemed to have third destination functionality. The application library destination APP is also deemed to have first destination functionality.
FIG. 8 is a flow diagram of a method of operation of a touch sensitive mobile device for enabling a user to employ a single discrete navigation gesture to navigate a mobile device destination set to select and launch a user selected child mobile device destination. The flow diagram includes the following steps:

    Step 140: On detecting user contact on the touch sensitive screen, displaying an intermediate navigation display screen depicting at least one parent mobile device destination icon.
    Step 141: On detecting continuous user contact on the touch sensitive screen displaying the step 140's intermediate navigation display screen at a parent mobile device destination icon of a user selected parent mobile destination, displaying another intermediate navigation display screen depicting at least one child mobile device destination icon associated with the user selected parent mobile device destination.
    Step 142: On detecting user release from the touch sensitive screen displaying step 141's intermediate navigation display screen, thereby terminating a user's single discrete navigation gesture,
