Method And System For Multi Application Rotation

The present invention relates to a method of controlling display of multiple applications simultaneously on a display device and an electronic device including a touch screen that implements the control method. Background of the Invention: As demand for smart phones, tablets, and other similar portable electronic devices has rapidly increased, research on user interface methods associated with a touch screen contained in the smart phones, the tablets, and the portable electronic devices has been actively conducted. One of the technical advancements in this direction is the concept of multi-window or multiview display, wherein multiple applications are simultaneously depicted on the display device. From single user perspective, while accessing applications in multi-window scenario, we came across situations where different applications are having their different best view modes e.g. portrait or landscape. In that scenario user will change applications orientation very frequently. That will result in user inconvenience, UI lagging, more GPU processing and more power consumption. When the user performs multi-tasking using a plurality of applications, there may be an inconvenience to the user in that the user continuously performs manipulation for switching a screen between applications, and there may be a drawback in that the user may not readily recognize or easily determine the progress of the applications executing tasks or operations. On the other hand, when a plurality of users use a single smart phone or tablet, there may be an inconvenience in that a workspace of each user may overlap each other. Additionally, in the current multi-window scenario it is almost impossible for multiple users to work on their different applications simultaneously, as all windows are aligned in same direction. Therefore, there is a need for a method for effectively displaying a plurality of applications in a multi-window (or multi-view configuration). Summary of the Invention: Accordingly, the present invention provides a method that displays simultaneously multiple applications on a display (in multi-window environment) and receives input from user(s) and rotates the application, independent of other applications, in any direction which is 3 convenient to the user or users. In an alternative, the present invention provides a method that displays simultaneously multiple applications on a display (in multi-window environment), detects location of user(s) with respect to the display device and rotates the applications, independent of other applications, in a direction which is convenient to the user or users.

The system, methods, and examples provided herein are illustrative only and not intended to be limiting. Embodiments of the present invention will be described below in detail with reference to the accompanying figures. Referring to Figure 1, the present invention provides a method (100) implemented in an electronic device for controlling display of plurality of application in a multi-window configuration. The method (100) comprises displaying (101) simultaneously a plurality of applications in a first display direction, receiving (102) a user input in respect of a first application and in response thereto, rotating a display direction of the first application to a second display direction. The method further comprises blocking (103) detection of rotation of the electronic device and displaying (104) the plurality of applications such that the first application is displayed in the second display direction and remaining application(s) is displayed in the first display direction. In an embodiment of the present invention, the plurality of applications is displayed in a multi-window configuration. In still another embodiment, the present invention may further comprise receiving (105) a user input in respect of at least one further application and in response thereto, rotating display direction of said at least one further application to a second display direction. Once the further application has been rotated, the method further comprises displaying (106) the plurality of applications such that the first application and said at least one further application are displayed in the second display direction and remaining application(s) is displayed in the first display direction. In another embodiment, the method of the present invention may further comprise storing (107) the user input in respect of the first application in a memory device. The stored user input can be used while launching of the first application i.e. for displaying (109) the first application in accordance with the user input thus stored the next time the first application is launched. 6 Likewise, in case a user input in respect of at least one further application such user input can be stored (108) in respect of said at least one further application in a memory device. The stored user input can be used while launching of said at least one further i.e. for displaying (110) said at least one further application in accordance with the user input thus stored the next time said at least one further application is launched. It can be seen that the above described method involves blocking detection of rotation of the electronic device, which is performed automatically. Because detection of rotation of the electronic device has been blocked, the each of the plurality of applications is rendered as per the user’s choice irrespective of the orientation of the electronic device. Some of the results of blocking detection of rotation of the electronic device include increasing user convenience, avoiding lagging of the user interface (which other happens), less amount of graphical processing and less power consumption. In an alternative, the present invention further provides a method (200) implemented in an electronic device for controlling display of plurality of application in a multi-window configuration which is based on NOT blocking detection of rotation of the electronic device. The method (200) in accordance with the aforesaid embodiment is illustrated in detail in figure 2 and comprises displaying (201) simultaneously a plurality of applications in a first display direction, receiving (202) a user input in respect of a first application and in response thereto, rotating a display direction of the first application to a second display direction and displaying (203) the plurality of applications such that the first application is displayed in the second display direction and a remaining application(s) is displayed in the first display direction. In contrast to the method (100) described above, the method (200) comprises detecting (204) a rotation of the electronic device and determining (205) a change in display configuration in response to an angle of rotation being in excess of a predetermined value. In case the angle of rotation being in excess of a predetermined value the method comprises displaying (206) the plurality of applications such that the first application is displayed in a third display direction and the remaining application(s) is displayed in a fourth display direction. According to the method (200), the applications are displayed after rotation (which is in accordance with the user inputs) and detection of rotation of the device is enabled. In case the device is rotated, the angle of rotation is determined and checked with a predetermined 7 threshold value. In case the angle of rotation is in excess of the predetermined threshold value, all of the applications are rotated and freshly displayed on the display device. In a preferred aspect of the invention, the third display direction is rotated with respect to the second display direction by 180 degree (or multiples of 180) and likewise, the fourth display direction is rotated with respect to the first display direction by 180 degree (or multiples of 180). Similar to what has been illustrated in figure 1, the method (200) may further comprise receiving (207) a user input in respect of at least one further application and in response thereto, rotating display direction of said at least one further application to a second display direction. Once the further application has been rotated, the method (200) further comprises displaying (208) the plurality of applications such that the first application and said at least one further application are displayed in the second display direction and remaining application(s) is displayed in the first display direction. In another embodiment, the method of the present invention may further comprise storing (209) the user input in respect of the first application in a memory device. The stored user input can be used while launching of the first application i.e. for displaying (211) the first application in accordance with the user input thus stored the next time the first application is launched. Likewise, in case a user input in respect of at least one further application such user input can be stored (210) in respect of said at least one further application in a memory device. The stored user input can be used while launching of said at least one further i.e. for displaying (212) said at least one further application in accordance with the user input thus stored the next time said at least one further application is launched. Without wanting to be limited, the user input in both of the aforesaid embodiments can be selected from a group comprising:  a screen reverse gesture to reverse a top side to a bottom side;  a screen reverse gesture to reverse a bottom side to a top side;  a screen reverse gesture to reverse a left side to a right side;  a screen reverse gesture to reverse a right side to a left side;  a drag gesture from a top side to a bottom side;  a drag gesture from a bottom side to a top side;  a drag gesture from a right side to a left side; 8  a drag gesture from a left side to a right side;  a drag gesture from a top side to a left side;  a drag gesture from a left side to a top side;  a drag gesture from a top side to a right side;  a drag gesture from a right side to a top side;  a drag gesture from a bottom side to a left side;  a drag gesture from a left side to a bottom side;  a drag gesture from a bottom side to a right side;  a drag gesture from a right side to a bottom side;  a screen rotate gesture;  a screen rotate icon activation; and  a motion to rotate the electronic device while touching the first application. It can be seen that in the aforesaid methods (100 and 200), the user provides manual input for rotating the application. In an alternative embodiment the method can be modified such that location of the user relative to the electronic device is automatically detected and the first application is rotated to the second direction based on the location of the user. In this embodiment, while the first application is rotated to the second direction, it is NOT essential that all applications which are being simultaneously being displayed are rotated. This aspect of the invention is illustrated in figure 3, which shows a flow chart of a method (300) comprising the steps of displaying (301) simultaneously a plurality of applications in a first display direction, detecting (302) location of a user relative to the electronic device and rotating (303) a display direction of the first application to a second display direction based on the location of the user. The method further comprises displaying (304) the plurality of applications such that the first application is displayed in the second display direction and remaining application(s) is displayed in the first display direction. Although not essential, the method (300) may further comprise rotating at least one further application to a third direction based on the location of the user. In this regard, the method (300) can receive (305) user input in respect of at least one further application and in response thereto, rotate display direction of said at least one further application to a third display direction. Once the further application has been rotated, the method further comprises displaying (306) the plurality of applications such that the first application is displayed in the 9 second direction, said at least one further application is displayed in a third display direction and remaining application(s) is displayed in the first display direction. In an alternative to steps 305 and 306 (which are based on manual input), the method (300) may further comprise rotating (308) at least one further application to a third direction based on the location of the user as sensed in the earlier step (302). Once the further application has been rotated, the method further comprises displaying (309) the plurality of applications such that the first application is displayed in the second direction, said at least one further application is displayed in the third display direction and remaining application(s) is displayed in the first display direction. Similar to the method illustrated in figure 2, the method (300) can enable detection of further rotation of the device or movement of the user with respect to the device, in which case, rotation of the electronic device is detected (310), a change in display configuration is determined (311) in response to an angle of rotation is in excess of predetermined threshold value and all of the applications are rotated and freshly displayed (312) on the display device. Especially in case where location of the user is automatically detected, the method (400) can be further elaborated as illustrated in figure 4 to comprise of the steps of displaying (401) simultaneously a plurality of applications in a first display direction, detecting (402) location of a first user relative to the electronic device and detecting (403) a first application as viewed by the first user. The method further comprises rotating (404) a display direction of the first application to a second display direction based on the location of the user and displaying (405) the plurality of applications such that the first application is displayed in the second display direction and remaining application(s) is displayed in the first display direction. Especially to cater to multi-user scenario, once the first application has been displayed in the second direction (with the remaining application(s) being displayed in the first direction), it is also possible to obtain orient any of the further application(s) to cater to the requirement of the plurality of users. This embodiment is illustrated in figure 4 and it can be noticed that the method (400) after the step of displaying (405) the plurality of applications such that the first application is displayed in the second direction and the remaining application(s) is displayed in the first 10 direction, the method can comprise a procedure for orienting a second application to suit the needs of a second user. The procedure for orienting the second application to suit the needs of the second user can comprise, detecting (406) location of the second user relative to the electronic device and detecting (407) a second application as viewed by the second user. Based on the above, the method further comprises rotating (408) a display direction of the second application to a third display direction based on the location of the user. Alternatively such procedure can comprise, receiving input from the second user in respect of a second application and rotating the display direction of the second application to a third direction (which is in accordance with the input provided by the second user) (409). Although not illustrated in figure 4, once the rotation of the second application has been performed, the method may further include displaying the plurality of applications such that the first application is displayed in the second display direction which based on (a) the location of the first user or (b) in accordance with the input received from the first user; the second application is displayed in a third display direction which is based on (a) the location of the second user or (b) in accordance with the input received from the second user; and the remaining application(s) is displayed in the first direction. The aforesaid process can be repeated for any further user(s) and as illustrated in figure 4, can comprise detecting (410) location of at least one further user relative to the electronic device and detecting (411) one further application as viewed by said at least one further user. Based on the above, the method further comprises rotating (412) a display direction of said one further application to further display direction based on the location of said at least one further user. Alternatively such procedure can comprise, receiving input from said one further user in respect of said at least one further application and rotating the display direction of the one further application to a further direction (which is in accordance with the input provided by the second user) (413). Now referring to figure 5, there is illustrated construction of an electronic device (500) that can implement the method as illustrated in any of figures 1 or 2. The electronic device can comprise a display device (501) for displaying simultaneously a plurality of applications in a first display direction, a user input receiver (502) for receiving a user input in respect of a first application, an electronic device rotation sensor (503) for detecting rotation of the 11 electronic device, and a controller (504) being in operational interconnection with the display device (501), the user input receiver (502) and the electronic device rotation sensor (503). While implementing the method illustrated in figure 1, the controller (504) is configured to rotate a display direction of the first application to a second display direction in response to receiving the user input, block detection of rotation of the electronic device and display the plurality of applications such that the first application is displayed in the second display direction and a remaining application(s) is displayed in the first display direction. On the other hand, while implementing the method illustrated in figure 2, the controller (504) is configured to rotate a display direction of the first application to a second display direction in response to receiving the user input, displaying the plurality of applications such that the first application is displayed in the second direction and remaining application(s) is displayed in the first direction, detect rotation of the electronic device, determine a change in display configuration in response to an angle of rotation being in excess of a predetermined value, and display the plurality of applications such that the first application is displayed in a third display direction and the remaining application(s) is displayed in a forth display direction. Now referring to figure 6, there is illustrated construction of an electronic device (600) that can implement the method as illustrated in figure 3. The electronic device can comprise a display device (601) for displaying simultaneously a plurality of applications in a first display direction, a sensor (602) for sensing location of user(s) relative to the electronic device (600), and a controller (603) being in operational interconnection with the display device (601) and the sensor (602). The controller (603) is configured to rotate a display direction of the first application to a second display direction based on the location of the user and display the plurality of applications such that the first application is displayed in the second display direction and remaining application(s) is displayed in the first display direction. Now referring to figure 7, there is illustrated construction of an electronic device (700) that can implement the method as illustrated in figure 4. The electronic device can comprise a display device (701) for displaying simultaneously a plurality of applications in a first display direction, a sensor (702) for sensing location of a first user relative to the electronic device (700), a sensor (703) for detecting a first application as viewed by the first user and a controller (704) being in operational interconnection with the display device (701), the sensor (702) for sensing location of the user and the sensor (703) for detecting the first application. 12 The controller (704) is configured to rotate a display direction of the first application to a second display direction and display the plurality of applications such that the first application is displayed in the second display direction and remaining application(s) is displayed in the first display direction, said second display direction being dependent upon the location of the first user. In the following paragraphs, the invention is explained with reference to some examples which are provided merely for the purposes of illustration. The present invention provides for window rotation of 2 or more windows in any direction independent of each other. The windows can be rotated either manually using finger, gesture or any other user input receiving means including but limited to mouse, roll-ball, keypads, etc. Alternatively, the rotation can be done automatically, by detecting the location of the user, for example using a camera sensor. Preferably, the detection of location of the user can be done such that the application which the user is viewing can also be sensed. This can be done, by way of example, be detecting eye position of the user(s). Especially in relation to operation of the electronic device by a single user, the user can rotate the applications in their best suited direction, which optimizes the device usage. On the other hand, when it comes to multi-user scenario, the feature of rotation can be preferably used to facilitate the multiple users to easily view or read or work on applications of their choice in the respective window. Especially with a mobile, the display device can be segmented so as to display two windows and rotation of the content of each window can be individually controlled by one or two users. In respect of tablets or display devices having a larger screen (as compared to mobiles), the display device can be segmented into 4 segments and rotation of the content of each window can be controlled independently by up to 4 users. Presently, multi-window feature allows user to open multiple applications at a time on single display device of an electronic device such as a phone screen but their viewing direction/alignment remains same. This makes very difficult for multiple users to work simultaneously on their apps at same time. In accordance with the teachings of the present invention, the users are provided the flexibility to rotate the multiple applications independent of each other. Additionally, the restrictions are cast on detection of change in display configuration of the electronic device. In one alternative, the sensors which provide input in relation to the angle of rotation of the electronic device are blocked (or in other words, the 13 input is not acted upon). In another alternative, a change in display configuration is detected only if the electronic device has rotated by an angle in excess of a threshold value, for example, 180o. Now referring to figure 8, there is illustrated a prior art scenario wherein a user launches two applications (801 and 802) on a mobile device for display on the associated display device. As it can be seen from figure 8a, which illustrates a first orientation direction of the mobile device, the first application 801 appears in a compressed form while the second application 802 appears in a normal form as per prior art. It can be further observed from figure 8b that in case the electronic device is oriented to a second orientation direction (which is 90o shifted with respect to the first orientation) the first application 801 appears in a normal form while the second application 802 appears in a compressed form as per prior art. Thus, it can be seen that neither the user is able to independently rotate the applications in accordance with his choice (or as per his location) nor does any rotation of the electronic device assists in displaying the first and the second applications in a manner optimal form. In terms of present invention, while the electronic device may initially display the first application and the second application in the first direction, similar to what is illustrated in figure 8a. However, since the first and the second applications are thereafter rotated independent of each other, as illustrated in figure 9, both the first application (801) and the second application (802) are now displayed in a normal form. Now referring to figure 10, the rotation of the first application (801) can be performed manually, for example, in respect of a touch screen display device by touching the screen and performing a rotation action (1001). Referring to figure 11a, in an alternative embodiment, the location of the user with respect to the electronic device is sensed (1101) and as illustrated in figure 11b, on the basis of the location of the user, the rotation of the first application (801) is rotated, while the second application (802) is displayed in the original direction. In case of a multiple user scenario, the orientation of the applications can be based on the inputs provided by one or more of users or alternatively based on the location of multiple users with respect to the electronic device. The electronic device even under this scenario may initially display the first application (801) and the second application (802) in the first direction, similar to what is illustrated in figure 8a. Thereafter, in one embodiment, the first user may provide command for rotation of the first application in a direction suitable to him, as illustrated by the rotation arrow (1201) shown in Figure 12. In response to the rotation 14 command which is received only in respect of the first application (801), the display direction of the first application is changed while the display direction of the second application is maintained (or not changed). Subsequent to the display of the first and the second applications, the electronic device either blocks detection of rotation of the electronic device or detects a change in display configuration only if an angle of rotation of the electronic device is in excess of a predetermined value. In an alternative mechanism, the electronic device detects the location of the first user and the second user with respect to the electronic device. The electronic device further detects whether the first user is viewing the first application or the second application (1202). Assuming that the first user is viewing the first application, the electronic device now rotates the first application in accordance with the location of the first user. The electronic device further detects whether the second user is viewing the first application or the second application (1203). Assuming that the second user is viewing the second application, the electronic device rotates the second application in accordance with the location of the second user. In the illustrated case, it however happens that the display direction of the second application is already in accordance with the location of the second user and hence, no action is taken. In case, it is detected that both the first user and the second user are viewing the first application (i.e. although the display device is displaying the second application, the same is not being viewed by either of the first user or the second user), the device may display the first application either in accordance with the location of the first user (in which case, the electronic device may prompt the second user to shift the location) or display the first application either in accordance with the location of the second user (in which case, the electronic device may prompt the second user to shift the location). In order to detect as to which application a particular user is viewing, reliance can be placed on the position of the eyes of the respective user, as illustrated in figure 12. While figure 12 shows the implementation of the present invention in an electronic device which is held in a portrait mode, figure 13 illustrates implementation of the present invention in an electronic device which is held in a landscape mode. Similar to what was described with reference to figure 12, in figure 13, the first user provides command for rotation of the first application in a direction suitable to him, as illustrated by the rotation arrow (1301) and in response thereto, the display direction of the first application is changed while the display direction of the second application is maintained (or not changed). In the alternative 15 mechanism, the electronic device detects the location of the first user and the second user with respect to the electronic device and the application being viewed by each of the first and the second user based on the position of the eyes (1302 and 1303). Thereafter, the electronic device now rotates the first application and/or the second application in accordance with the location of the first user and/or the second user. It may be noted that the number of applications being simultaneously displayed by the electronic device is not restricted by the implementation of the present invention. For example, considering a case wherein a display device is displaying four applications (1401, 1402, 1403 and 1404) as illustrated in figure 14, the method of the present invention can be implemented even under the aforesaid scenario. As illustrated in figure 15, assuming that four different users are viewing the four applications (1401, 1402, 1403 and 1404) displayed by the display device, the electronic device in one embodiment may: receive rotation command from the first user in respect of the first application (1401), as illustrated by the hand gesture (1501), receive rotation command from the second user in respect of the second application (1402), as illustrated by the hand gesture (1502), receive rotation command from the third user in respect of the third application (1403), as illustrated by the hand gesture (1503), receive rotation command from the fourth user in respect of the fourth application (1404), as illustrated by the hand gesture (1504). In response thereto, the display directions of each of the first application, the second application, the third application and the fourth application is changed in accordance with the respective command. In the embodiment illustrated in figure 15, it is assumed that the gesture command from the fourth user in respect of the fourth application is to retain the display direction and hence, the display direction of the fourth application is maintained (or not changed). In the alternative mechanism, the electronic device detects the location of each of the first, second, third and fourth users with respect to the electronic device. The electronic device further detects the application being viewed by each of the first, second, third and fourth users based on the position of the eyes (as illustrated by 1505, 1506, 1507 and 1508). 16 Thereafter, the electronic device now rotates one or more of the first to the fourth applications in accordance with the in accordance with the location of the first user to fourth users. The present invention can be provide substantial advantages as compared to the conventional processes. By way of non-limiting example, in case an electronic device is being used by a single user in multi-window mode, the present invention can provide for:  Lagless: No lag while switching between applications since no rotation is performed;  User Convenience: Due to fixed screen directions, less re-rendering will occur which will minimize delays or fluctuations and user will get a feel of smooth and fast work experience;  Power Saving: Reduce number of renderings will result in less GPU operations or processing and hence will increase overall battery life;  Better Resource Utilization: Reduce number of renderings will put less load on GPU hence it can be utilize to handle other tasks;  Faster processing of the applications due to better utilization of CPU/ GPU resources;  Accidental touch avoidance: The accidental touch between multiple applications can be avoided. By way of another non-limiting example, in case the electronic device is being used by multiple users in multi-window mode, the present invention can provide for:  Users Convenience: Application windows can be easily rotated in desired user directions, which will be very convenient for multiple users for using them. They can view/read/work on their respective application windows simultaneously.  Quick Alignment: By using camera sensor, automatically application windows can be aligned quickly in respective user direction.  Accidental Touch Avoidance: It will avoid accidental touch between multiple applications while accessing them by more than one user.  Extendibility: It can be easily extendible to N number of windows for N number of users. Presently possible use cases are Mobile (2 windows) and Tablet devices(4 windows). Also applicable for both touch and non-touch devices.  Time Saving: When multiple users work on their application independently from different directions then obviously the time taken by them to finish the task will be less as compared to the time when they all do it from single direction. 17 While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended.
