DETAILED DESCRIPTION OF THE OF PREFERRED EMBODIMENT
In the accompanying drawings reference numeral 1 indicates an electronic device according to the present invention.
The electronic device 1 is preferably a portable or mobile device. For example the electronic device 1 can be a mobile phone, and in particular a so-called smart phone, or a tablet.
The electronic device 1 comprises a touch-screen display 10.
By means of the touch-screen capabilities of display 10 the device 1 is able to detect the position in which a user touches the display and the possible trajectory designed by the user moving his/her finger while it is in contact with the surface of the display.
Of course parts of the body other than fingers can be used, although fingers are the most commonly employed.
This technology is per se well known and will not be disclosed in further detail.
The electronic device 1 comprises a memory 20 configured to store data representative of a plurality of categories of sources of information. The sources of information can be, for example, other electronic devices/apparatuses, possibly associated with users/owners thereof, which can send data/information to the electronic device 1. Other possible sources of information can be websites and/or web services (such as, for example, news services provided by online newspapers or magazines) which, based on some agreement or subscription, send data/information to the electronic device 1. The categories in which the sources are divided can be related, for example, to the extent to which the source can be considered important/interesting by the user. By means of the technique discloses herein, the user can easily and quickly set the importance/interest of each source.
Preferably, each of said category is associated with a respective rating value representative of a rating attributed to each of said categories. Thus each category can be associated to a rating value which is included, for example, between “1” and “6”, wherein “1” identifies the most important/interesting source(s), while “6” identifies the least important/interesting source(s).
Advantageously each category is associated with respective notification data ND1-ND6. As will become more clear in the following, the notification data ND1-ND6 are used to notify the user that information has been received from a source belonging to a determined category.
FIG. 7 schematically shows an example of a possible logic structure of memory 20: a number of records R are stored, each comprising: a first field F1 in which a data item representative of a category is stored; a second field F2 in which the rating value associated with the category is stored; a third field F3 in which notification data ND1-ND6, associated with the category, are stored.
The electronic device 1 comprises a processing unit 30. Preferably the processing unit 30 manages the overall functioning of the electronic device 1.
Preferably, given a determined source of information, the processing unit 30 cooperates with the touch-screen display 10 for displaying in a first position P1 on said display 10 an item X representative of said determined source of information (FIG. 1).
For example the item X can be an icon, a sign, a graphic symbol, a group of characters which is/are associated to the determined source of information so that the user, when looking at the item X, recalls the determined source of information.
The processing unit 30 is configured to determine a reference position RP on the display 10. In one embodiment, the reference position RP can be determined as the geometrical center of the display 10, or the geometrical center of a window shown on the same display.
Preferably a reference item is displayed at the reference position RP, so as to clearly identify the same.
The processing unit 30 is also configured to cooperate with the display 10 to detect a gesture G applied to the item X.
The gesture G is applied by the user, for example by means of one of his/her fingers. Of course also other parts of the body can be used. However, the most practical and simple is the use of a finger.
The gesture G is recognized by the processing unit 30 cooperating with the touch-screen capabilities of the display 10.
The gesture G defines, on the display 10, a trajectory which starts in the first position P1, i.e., the initial position of the item X, and ends in a second position P2 of the display 10.
This means that the user touches the screen at the first position P1 and, keeping the finger (or, in general, the involved part of his/her body) in contact with the display, moves said finger on the display, i.e., the user changes in time the position in which he/she is touching the screen, until the second position P2 is reached.
In practical terms the trajectory of the gesture G is defined by the substantially continuous sequence of positions in which, in time, the finger of the user contacts the touch-screen display 10 starting from the first position P1 and ending in the second position P2.
The gesture G can be, for example, a drag gesture. The gesture G can also be a swipe gesture or a flick gesture. In general the gesture G can be any gesture that allow the user to modify the position of the item X on the display 10 by touching the same display.
The processing unit 30 is configured to cooperate with the display 10 to move the item X along the trajectory defined by the gesture G while the same gesture G is executed, so that the item X directly follows the movement imparted by the user, as if it were dragged by the user's finger. Therefore, after the gesture G is executed, the item X is represented at the second position P2 (shown in dashed line in FIG. 1).
Upon recognition of the gesture G, the processing unit operates on the memory 20 to associate said determined source of information to one of said categories, based at least on the second position P2.
Preferably, the processing unit 30 calculates the distance D between the second position P2 and the reference position RP and, based on the calculated distance D, associates the determined source to one of the categories.
In particular, in memory 20 each rating value is associated with a respective possible distance or range of distances between the second position P2 and the reference position RP, as schematically shown in the table of FIG. 7, wherein the possible distances or ranges of distances D1-D6 are stored in field F 4.
Once the distance D between the second position P2 and the reference position RP has been determined, the processing unit 30 selects the rating value, and consequently the category, that are associated to that distance D, and associates the determined source represented by the item X to the selected category/rating.
FIG. 8 schematically shows a possible logic implementation of the association between some sources of information S1-S3 with a category: a table is provided, in a column of which data representative of the sources S1-S3 are stored and, on the same row, in a second column, data representative of the associated category are stored.
Preferably, the rating values are associated to the respective distances or ranges of distances according to a monotone relationship. This means that, for example, shorter distances are associated to higher ratings. From a graphical point of view this implies that the closer the second position P2 to the reference position RP, the higher the rating associated to the source represented by item X.
In a preferred embodiment, the rating associated to the determined source of information is substantially proportional to the distance D between the second position P2 and the reference position RP.
It is to be noted that only one item (namely item X) representative of a source of information has been represented in FIG. 1 for sake of clarity. However, in the representation displayed on the display 10 a higher number of items, each representative of a respective source of information, can be shown, so that the importance/interest of each source of information can be set by means of the technique disclosed herein.
The electronic device 1 comprises a receiving module RM that is adapted to receive information and data associated therewith representative of a transmitting source of said information. In practical terms the receiving module RM can be any hardware/software component which may provide the electronic device 1 with connection capabilities. The connection can be based on any suitable technology, such as for example GSM, UMTS, LTE, WiFi, etc.
Once the electronic device 1 receives, by means of the receiving module RM, at least one signal including information and source data, the latter being representative of the transmitting source of such information, the processing unit 30 compares the source data with data representative of the determined source, i.e., the source represented by item X.
If the transmitting source is the determined source associated with the item X, then the processing unit 30 selects in the memory 20 the notification data ND1-ND6 associated with the category of the determined source, and generates a notification signal based on the selected notification data.
The notification data ND1-ND6 describe how a notification of the reception of information/data from a source, associated to a certain category/rating, will be performed.
For example the notification data may specify whether a graphic alert is displayed and/or a sound is generated upon reception of said information/data.
The kind of notification that is generated thus depends on the rating (i.e., the category) associated to the source, so that information/data received from important/interesting sources will be notified in a more apparent/visible way, whereas information/data received from unimportant/dull sources will be notified in a more quiet/concealed way.
The level of importance/interest is set by the user by means of the gesture G, as herein disclosed.
By way of example, the notification data ND1-ND6 can describe how an item displayed on the display 10, and representative of a certain source of information, is shown when information/data is/are received from that source.
In practical terms, each source of information is displayed on the display 10 in a diagram as the one on FIG. 1. Each source is represented by a respective icon. The notification data ND1-ND6 describe possible graphic changes in the representation of the icons when information/data is/are received from the respective source. For example, when information/data is/are received from an important source, the respective icon can be enlarged and/or can start blinking and/or can be highlighted in other ways and/or some sounds can be generated by the electronic device 1; by contrast, when information/data is/are received from an unimportant source, the respective icon undergoes minor changes (for example, in case of the reception of an email message, a small envelope appears on or close to the icon).
FIG. 11 shows two icons represented on the display 10: one icon (the star) is representative of Source no. 1, the other icon (the hexagon) is representative of Source no. 2.
Source no. 1 is more important/interesting than Source no. 2; in fact, the star is closer to the reference position RP than the hexagon.
FIG. 12 shows how the reception of a message from the two sources can be represented: the icon of Source no. 1 starts blinking/flashing, while the icon of Source no. 2 is merely associated with a little envelope.
It has to be noted that the invention is not limited to these examples; several other notification techniques can be employed.
In a preferred embodiment, also the notification data ND1-ND6 can be customized by the user. Accordingly, the user can decide how important/unimportant notifications should be brought to his/her attention.
Preferably the processing unit 30 is configured to determine one or more auxiliary distances DX1, DX2 between the reference point RP and one or more auxiliary points A1, A2 of the trajectory defined by the gesture G. Advantageously the auxiliary points A1, A2 comprise points interposed between the first position and the second position P1, P2. FIG. 4 schematically shows two auxiliary points, by way of example.
For each auxiliary point A1, A2, the processing unit 30 determines auxiliary rating values associated to the respective auxiliary distances. In practical terms, for each auxiliary point A1, A2 the processing unit determines the rating that would be attributed to the determined source if the gesture G would end in that auxiliary point, i.e., if the second position P2 would coincide with that auxiliary point.
In order to determine said auxiliary rating values, the processing unit 30 can for example employ the table of FIG. 7: the auxiliary distances DX1, DX2 are compared with the distances D1-D6 in fields F4 and, when a match is found, the corresponding rating values in field(s) F2 are assumed as the auxiliary rating values.
The processing unit 30 is also configured to cooperate with the display 10 to display an indicator ID1 of each auxiliary rating value when the trajectory defined by the gesture G reaches the corresponding auxiliary point.
The indicator ID1 can be a graphic symbol, a number, a character that provides an immediate idea as to the rating that would be attributed to the source should the gesture G end in that point.
Preferably each indicator ID1 is shown when the trajectory is within a certain distance from the respective auxiliary point. Preferably each indicator ID1 is shown close the respective auxiliary point.
FIG. 5 shows, by way of example, two numerical indicators “3”, “4” displayed close to the respective auxiliary points A1, A2. This means that, when the gesture G reaches the auxiliary point A1, the user is informed that, should the gesture G end in that point, the rating that would be given to the determined source of information is “3”. The same applies to the auxiliary point A2 and the auxiliary rating value “4”.
In a preferred embodiment, shown in FIG. 5, the rating indicator ID1 is represented also close to the second position P2. Actually the system does not know that the gesture G ends in the second position P2 until the user moves the finger away from the display 10. Thus the second position P2 is preferably treated as an auxiliary point during execution of the gesture G and a rating indicator ID1 is shown also close to the second position P2. In the specific example of FIG. 5, the auxiliary rating value “5” is attributed to the second position P2 and the relevant indicator ID1 is shown close to the same second position P2.
Preferably the processing unit 30 is configured to determine a direction followed by the trajectory defined by the gesture G. If the trajectory is substantially rectilinear, the direction is identified quite easily. If the trajectory is curved, it can be approximated with one or more segments, and the direction of one of the segments can be selected.
Preferably the category to which the determined source is associated is identified also based on said direction. For example, given the reference position RP in the center of the display, six categories are available: three categories are selected by respective distances D1up, D2up, D3up, which extend in the upper half of the display, whereas the remaining three categories are selected by respective distances D1 down, D2down, D3down which extend in the lower half of the display. This embodiment is schematically shown in FIG. 9. FIG. 10 show, by way of example, a possible correspondence between the distances D1up-D3up, D1down-D3down and the distances D1-D6 of FIG. 7.
In a preferred embodiment, once the processing unit 30 determines the direction followed by the trajectory defined by the gesture G, it is configured to execute a determined command based on said direction.
In practical terms, the processing unit 30 is associated with a memory, which can be or can be included in the memory 20, wherein two or more commands are stored, each associated with a respective possible direction of the trajectory. The trajectory detected analyzing the gesture G is thus compared with the pre-stored directions and, once a match is found, the corresponding command is selected and executed.
Preferably the command that is executed includes one or more operations related to the determined source and/or to information received from the determined source.
For example, if the gesture G is directed to the upper part of the display 10, then the processing unit 30 will start a telephone call to the determined source (which is, in this specific case, a person associated to a different electronic device, such as a cell phone or smart phone), whereas if the gesture G is directed to the lower part of the display 10, then the processing unit 30 will automatically activate an email application and present the user a new blank email message, ready to be sent, addressed to the determined source (see FIGS. 6a-6b).
In a preferred embodiment, the processing unit 30 is configured to cooperate with the display 10 to show on the same display 10 indicators ID2 of commands that can be executed while the trajectory of the gesture G is drawn by the user.
More in detail, for each of the aforementioned auxiliary points, the processing unit 30 determines a direction of the tract of trajectory included between the first position P1 and the relevant auxiliary point. Again, if the trajectory is not rectilinear several rectification or approximation methods can be used. Based on said direction, the processing unit determines which command is associated with the same direction, i.e., the command that would be executed if the gesture G would finish in the respective auxiliary point, and displays an indicator ID2 descriptive of that command.
In the simple example of FIGS. 6a-6b, all the auxiliary points of FIG. 6a are associated with the “call” command, while all the auxiliary points of FIG. 6b are associated with the “email” command.
It is to be noted that the processing unit 30 can be realized as a single microprocessor or a group of microprocessors cooperating in order to carry out the functions herein disclosed and claimed.
Preferably the processing unit 30, the receiving module RM and the memory 20 are part of the control circuit of which the electronic device 1 is natively provided. According to the invention such control circuit can be programmed in order to perform the operations herein disclosed and claimed.
The invention achieves important advantages. Firstly the invention provides an easy, user-friendly and reliable way to manage data received by an electronic device provided with connection capabilities, and in particular by a smart phone.
Furthermore, the invention provides a fancy and intuitive way to manage data received by an electronic device provided with connection capabilities, through which the user can easily handle large amounts of data.
