Alternatively, or in addition to the touch of the user, the user interface can be operated by a pointing device such as a mouse, a keyboard or a touchpad.
FIGS. 2 to 9 show schematic representations of a first and second apparatus according to an example embodiment of the invention and their functions according to example embodiments of the invention. It is to be noted that the first apparatus 100 and the second apparatus 200 are both apparatuses according to an embodiment of the invention, the processor 120 of which apparatuses is configured to operate as a first processor and/or as the second processor in order to carry out functions in the role of the first apparatus 100 or the second apparatus 200. Hereinafter the term first apparatus is used to refer to an apparatus, the processor of which operates as a first processor, i.e. to the sending, or in some example embodiments the master, apparatus. Accordingly, hereinafter the term second apparatus is used to refer to an apparatus, the processor of which operates as a second processor, i.e. to the receiving, or in some example embodiments the slave, apparatus. It is to be noted that all functions and/or operations described are executed by the processor 120 of the first 100 or the second 200 apparatus, i.e. the processor of the first 100 and/or second 200 apparatus is configured to cause carrying out the function and/or operations.
FIG. 2 shows the first apparatus 100 and the second apparatus 200 being brought to proximity of each other. The proximity is understood to mean physical closeness and in an example embodiment the first and second apparatus are preconfigured to a certain proximity limit, for example physical touching of the devices or the devices being within a certain distance of each other. In a further example embodiment, the user of the device defines a setting for the proximity limit for each situation separately or a default setting for all situations.
As the first and second apparatus are brought to proximity of each other the processor of both the first 100 and the second 200 apparatus is configured to cause recognizing the proximity of the other apparatus. The recognition is, in an example embodiment, carried out using proximity sensors, such as magnetic, optical, electrical or mechanical sensors, or by using communications protocols such as Bluetooth, wireless local area network (WLAN), radio frequency identification (RFID) or near field communication (NFC). In a further example embodiment, the proximity recognition is carried out using imaging, by imaging the apparatus in proximity or a code such as a QR-code or bar-code imprinted thereon, or by using position detection with systems such as global positioning system (GPS). In a further example embodiment, the first 100 and second 200 apparatus are connected with a hardware link, such as a universal serial bus (USB) cable.
In an example embodiment, the proximity recognition function is active at all times, or alternatively it may be activated and deactivated by the user of the apparatus.
FIG. 3 shows a schematic representation of a first 100 and second 200 apparatus according to an example embodiment of the invention as the proximity recognition has been completed. The displays of both the first 100 and the second 200 apparatus show a display object, or a symbol, 310,320 indicating that the proximity of another apparatus has been recognized. In a further example embodiment, the symbols on the displays are similar or different, or only the display of the first or the second apparatus displays the symbol. In addition or alternative to a symbol being displayed, a further indication is given to the users, for example using audio or tactile indication.
FIG. 4 shows a schematic representation of a first 100 and second 200 apparatus according to an example embodiment, the first apparatus 100 having an application, or app, 150, the icon of which is shown on the display of the first apparatus 100. Alternatively, the app 150 is being executed by the processor of the first apparatus and the content of the application is shown on the display of the first apparatus 100. The user of the first apparatus 100 wishes to share the app 150, or some content therein, with the user of the second apparatus 200. In order to do so, the user of the first apparatus 100 slides or pushes the application towards the second apparatus 200, i.e. provides a first user input or user gesture. In an example embodiment, the sliding is carried out with a touch sensitive display, i.e. by sliding for example a finger on or above the touch sensitive display of the first apparatus 100. In a further example embodiment, the direction of the sliding gesture points towards the second apparatus 200, if for example a plurality of second apparatuses 200 are in proximity of the first apparatus 100. In a further example embodiment, for example the speed of the sliding gesture determines the distance of the slide, if for example a plurality of second apparatuses 200 is in the proximity of the first apparatus 100 in the same direction but on different distances therefrom. In a still further example embodiment, the direction of the slide gesture is defined in three dimensions, e.g. by using arcuate gestures or taps. In a further example embodiment, the gesture is performed by enlarging the object 150 in such a way that its edges would cover one or more apparatuses 200. The enlarging gesture is hereinafter also referred to as a slide gesture, as the gesture slides the edge of object 150 to the area of another apparatus 200.
FIG. 5 shows a schematic representation of a first 100 and second 200 apparatus according to an example embodiment after the app 150 has been pushed or slid into the second apparatus 200. The display of the second apparatus 200 shows a prompt 510, e.g. a small window, a notification bar or a button, enquiring the user of the second apparatus 200 to approve the sharing of the app 150 that has been slid from the first apparatus 100. In an example embodiment, the user either accepts or declines the app sharing by giving input using e.g. a touch sensitive display. In a further example embodiment, the user of the second apparatus 200 is presented with further choices, either by default, or to be opened from a further display object such as a further menu. The further choices comprise for example accepting the sharing of the app 150 only once or accepting all future sharing from the first apparatus 100, i.e. pairing the two apparatuses or choosing a trusted status from one or more alternative trust levels to the first apparatus 100. The pairing or trusted status is in an embodiment stored in the memory of the second apparatus 200 or in the memory of both the first 100 and the second 200 apparatus. In addition or alternatively the further choices comprise for example blocking all sharing from the first apparatus 100 in the future, or accepting sharing from the first apparatus 100 for a given period of time. In a further example embodiment, the user of the second apparatus is presented with further information about the sharing of the app 150, for example information on the app 150, the version thereof, the identity of the user of the first apparatus 100, or on the configuration of the first apparatus 100.
FIG. 6 shows a schematic representation of a first 100 and a second 200 apparatus according to an example embodiment after the user of the second apparatus has approved sharing the app 150 that has been pushed or slid into the second apparatus 200. After approval, the second apparatus 200 determines, or detects, whether the app 150 to be shared exists in the second apparatus 200, e.g. in the memory thereof. If the app 150 is present in the second apparatus 200, the app is automatically executed in an example embodiment, or the display object for executing the application, e.g. an icon thereof, is highlighted, for example by making it move or making it bigger, thus indicating to the user the possibility of executing the app 150. It is to be noted that the second apparatus 200 and the first apparatus 100 in an example embodiment run different operating systems.
If the app 150 is not present in the second apparatus 200, the second apparatus 200 determines whether the app 150 is compatible with the operating system of the second apparatus 200, whether the app 150 is available for download for example in an application store or a similar location, and whether the app 150 is free or must be purchased. The second apparatus accordingly presents the user with a prompt 610. If the app 150 is incompatible with the second apparatus 200, the user is so informed. If the app 150 is available for download, the user is prompted to authorize or decline the download and/or the purchase. In a further example embodiment, since the user of the first apparatus 100 has already purchased the application, she is able to allow the user of the second apparatus 200 to download and use the application for free indefinitely or for a limited time, e.g. by providing a license number to the user of the second apparatus automatically with the sharing or manually afterwards. After the user of the second apparatus 200 has approved the download and/or purchase, the app 150 will be downloaded, installed and available to be executed as hereinbefore described. In a further example embodiment, the user of the first apparatus 100 has received a right for side-by-side use of the app 150, for purposes of use with connected apparatuses. In such a case the user of the second apparatus 200 does not need to purchase a license to run the application when operated in conjunction with the first apparatus 100.
FIG. 7 shows a schematic representation of a first 100 and a second 200 apparatus according to an example embodiment and the shared app 150 being executed on both apparatuses. The first 100 and the second 200 apparatus display either a similar view of the app 150, share the same view of the app 150 or both apparatus display a view of the app 150 in accordance with the preferences, the operating system, or the version of the app 150 in each apparatus. As the app 150 is being executed in the first 100 and the second 200 apparatus, the users can exchange objects 710, e.g. files, app specific objects, or media, from one apparatus to another. The exchange is effected by pushing or sliding the objects in a manner similar to that of app sliding or pushing as described hereinbefore. It should be noted that the exchange of objects is applicable in both directions although not shown in FIG. 7.
FIG. 8 shows a schematic representation of a first 100 and second 200 apparatus according to an example embodiment and the shared app 150 being executed on both apparatuses. In addition to showing a view of the app 150 as hereinbefore described, the first 100 and the second 200 apparatus display automatically, or in response to user input, a shared app area 810. With the shared app area 810 displayed in both the first 100 and the second 200 apparatus, the users can exchange objects 820,830 840, e.g. files, app specific objects, or media, from one apparatus to another and/or create a shared object collection. The exchange is effected by pushing or sliding the objects into the shared app area 810 in a manner similar to that of app sliding or pushing as described hereinbefore. It should be noted that the exchange of objects is applicable in both directions although not shown in FIG. 8.
FIG. 9 shows a schematic representation of a first 100 and a second 200 apparatus according to an example embodiment, and the shared app 150 being executed on both apparatuses. The shared app 150 is spread to the display of both the first 100 and the second 200 apparatus, thus making the display surface area available for the app larger, e.g. for purposes of viewing a document or media such as video in a larger size. In an example embodiment, the user interface of both apparatuses is used to control the app 150, or alternatively the user interface of either the first 100 or the second 200 apparatus has control, i.e. one of the first 100 and the second 200 apparatus is a master apparatus and the other one a slave apparatus.
FIG. 10 shows a schematic representation of a first and a plurality of second apparatuses according to an example embodiment of the invention and their functions according to an example embodiment of the invention. The app 150 to be shared is pushed or slid to each second apparatus 200 as hereinbefore described with a single second apparatus 200. Each second apparatus 200 carries out the functionalities hereinbefore described. Furthermore, it is to be noted that each apparatus may have a similar, shared, or its own view of the app 150 as hereinbefore described or the app 150 can be spread to the displays of each apparatus. In an example embodiment, if the first apparatus 100 leaves the proximity of the plurality of second apparatuses 200, the second apparatuses 200 continue to share the application 150, or the user of a second apparatus 200 of the plurality of the second apparatuses can define that the sharing is terminated, if the first apparatus leaves the group. In a further example embodiment, each second apparatus 200 exchanges content only via the first apparatus 100, or each second apparatus 200 exchanges content also with other second apparatuses 200. In a further example embodiment, each apparatus in the group approves or declines sharing with each further apparatus.
