## Background
FIELD OF THE INVENTION
The present invention generally relates to alert presentation and more particularly to deferring alerts.
BACKGROUND OF THE INVENTION
Many software applications in the prior art display alerts to the user. For example, messaging applications display message alerts, calendar applications display meeting reminders and clock applications can display alarm alerts. This type of alerting is used in electronic devices of all sizes, including mobile communication terminals, personal digital assistants (PDAs) as well as personal computers.
Often the user is allowed to acknowledge the alert, whereby the alert is deleted, or to delay the alert such that it reappears at a time in the future.
While the user interfaces to handle alerts of the prior art allow the user to perform most functions, the user interfaces are awkward and inefficient to use.
Consequently, there is a need for an improved user interface to manage alerts.

FIG. 1 illustrates an example of a cellular telecommunications system in which the invention may be applied. In the telecommunication system of FIG. 1, various telecommunications services such as cellular voice calls, www/wap browsing, cellular video calls, data calls, facsimile transmissions, music transmissions, still image transmissions, video transmissions, electronic message transmissions and electronic commerce may be performed between a mobile terminal 100 according to the present invention and other devices, such as another mobile terminal 106 or a stationary telephone 119. It is to be noted that for different embodiments of the mobile terminal 100 and in different situations, different ones of the telecommunications services referred to above may or may not be available; the invention is not limited to any particular set of services in this respect.
The mobile terminals 100, 106 are connected to a mobile telecommunications network 110 through RF links 102, 108 via base stations 104, 109. The mobile telecommunications network 110 may be in compliance with any commercially available mobile telecommunications standard, such as GSM, UMTS, D-AMPS, CDMA2000, FOMA and TD-SCDMA.
The mobile telecommunications network 110 is operatively connected to a wide area network 112, which may be Internet or a part thereof. A server 115 has a data storage 114 and is connected to the wide area network 112, as is an Internet client computer 116.
A public switched telephone network (PSTN) 118 is connected to the mobile telecommunications network 110 in a familiar manner. Various telephone terminals, including the stationary telephone 119, are connected to the PSTN 118.
An embodiment 200 of the mobile terminal 100 is illustrated in more detail in FIG. 2. The mobile terminal 200 comprises a speaker or earphone 222, a microphone 225, a touch-sensitive display 223 and a set of keys 224.
The internal component, software and protocol structure of the mobile terminal 200 will now be described with reference to FIG. 3. The mobile terminal has a controller 331 which is responsible for the overall operation of the mobile terminal and is preferably implemented by any commercially available CPU (“Central Processing Unit”), DSP (“Digital Signal Processor”) or any other electronic programmable logic device. The controller 331 has associated electronic memory 332 such as RAM memory, ROM memory, EEPROM memory, flash memory, hard drive, optical storage or any combination thereof. The memory 332 is used for various purposes by the controller 331, one of them being for storing data and program instructions for various software in the mobile terminal.

The mobile terminal also has a SIM card 330 and an associated reader. As is commonly known, the SIM card 330 comprises a processor as well as local work and data memory.
Now follows a scenario presenting a user interface according to an embodiment of the present invention.
FIGS. 4a-d illustrate schematic screen views of a user interface that can be embodied in the mobile terminal of FIG. 2.
In FIG. 4a, an alert is presented, comprising an icon 452 and a text alert 451 on a screen 450. In this example, a message has been received, whereby the icon 452 is depicted as an envelope. As is known per se, the icon 452 is related to the alert in question. For example, if the alert is an alarm, the icon 452 could be depicted as a clock, or if the alert is a reminder for an appointment, the icon 452 could be depicted as a calendar icon or a graphic associated with the appointment. The icon 452 can be a static icon or it could also be an animation, where the icon is animated at least part of the time. The text alert 451 is related to the alert in question. Optionally, no text alert 451 is presented.
In FIG. 4b, the user has selected the icon 452 and drags it to the right. Depending on what action the user desires to perform with the alert, the user could drag the icon 452 in different directions. For example, if the user drags the icon 452 to the left end of the screen to a delete action 455, the alert is deleted. If the user drags the icon 452 to the top of the screen 450 to a place action 456, the alert can be associated with a place. This can for example be performed by querying the user what place to associate the alert with or using an internal Global Positioning System (GPS) receiver. If the user drags the icon 452 to the bottom of the screen 450 to a save action 457, the alert is saved. In the example illustrated in FIG. 4b however, the user drags the icon 452 to the right towards a later action 454. In this embodiment, the labels 454, 455, 456, 457 are only shown on the display once the user presses the icon 452.
Optionally, a highlight 459 is shown to indicate what action the user is approaching. The highlight can be any suitable visual indication, e.g. a solid line, a pulsating line, an animation on that side of the screen, etc. A timeline 458 can be displayed for indication at what later time the alert will be deferred to reappear.
The user then flicks the icon 452 to the right, to defer the alert. Depending on the momentum of the movement of the icon 452, which depends on the movement of the user input on the touch-sensitive display, such as a finger or a stylus, the alert is deferred sooner or later. The momentum can for example be determined by the speed of the movement of the icon 452. In other words if the user pushes the icon 452 slowly to the right, the alert is deferred to a time soon in the future, e.g. in 15 minutes. On the other hand if the user flicks the icon 452 to the right very quickly, the alert is deferred to a much later time, e.g. in two days. There are many other deferral times that can be determined between the 15 minutes and two days, corresponding to a speed of the icon 452 between the speed for 15 minutes and the speed for 2 days. Optionally, the various times that are available could be user-configurable. The speed can be calculated as an average speed of the whole movement, or the speed at the end of the movement. Calculating the speed only on the end of the movement gives a greater effect of flicking the icon.
Once the user flicks the icon 452 to the right, the timeline 458 can move accordingly, and optionally labels (not shown) are displayed adjacent to the timeline 458, showing an animated sequence of when the alert will be deferred to reappear. Optionally, as a playful bounce effect, if the icon 452 is flicked to the right with too much speed, it bounces back and the alert is not deferred. The user can then try again to move the icon 452 to the right with less speed. If the determined deferral time for an appointment reminder is after the start time of the associated appointment, the playful bounce effect can be shown, or the deferral time can be redetermined to be the start time of the associated appointment.
In FIG. 4c, it is shown how the icon 452 has settled at a place in time 453 in relation to the timeline 458.
Optionally, as shown in FIG. 4d, a text 460 is shown on the display indicating when the alert is deferred to. Alternatively or additionally, a voice synthesizer can generate an audio message indicating when the alert is deferred to.
FIGS. 5a-b illustrate schematic screen views of a user interface that can be embodied in the mobile terminal of FIG. 2.
In FIG. 5a an alert is presented in much the same way as described in conjunction with FIG. 4a above. The alert comprises an icon 564 and a text alert 565 on a screen 550. In this example, an alarm clock has been set off, whereby the icon 565 is depicted as a clock. The icon 565 can be a static icon or it could also be an animation, where the icon is animated at least part of the time. The text alert 565 is related to the alert in question. Optionally, no text alert 565 is presented.
As illustrated in FIG. 5b, in this embodiment, the angle at which the icon 565 is moved to the right affects at what time the alert will be deferred to. If the icon 565 is moved to the right end of the screen at a sharp angle upwards, as indicated by an arrow 561, the alert can be deferred to a time soon in the future, e.g. in 15 minutes. On the other hand if the icon 565 is moved to the right end of the screen at a sharp angle downwards, as indicated by an arrow 562, the alert is deferred to a much later time, e.g. in two days. Other angles in between the two angles 561, 562 shown in FIG. 5b would result in times between the times that would be determined for the two shown angles 561, 562. For example, a movement of the icon 565 straight to the right could result in the alert being deferred an hour. Optionally, angle as well as speed are considered when the deferral time is calculated.
After the time of deferral is determined, the user can optionally be informed as shown in FIG. 5c. A text 560 is shown on the display indicating when the alert is deferred to. Alternatively or additionally, a voice synthesizer can generate an audio message indicating when the alert is deferred to.
It is to be noted that while it is described above to move the icon to the right to defer an alert, it is equally possible to have a device where use any suitable direction is used to defer an alert.
FIG. 6 is a flow chart illustrating a method according to an embodiment of the present invention that can be executed in the mobile terminal of FIG. 2. This method corresponds to the scenario disclosed above in conjunction with FIG. 4a-d. 
In a present alert step 680, an alert is presented, such as an alert for a new message, an alarm, a reminder for an appointment, a low battery warning etc.
In a detect user input movement step 682, a movement of the user input is detected, where the user input is associated with the alert. For example, when the user input uses a touch-sensitive display this user input can be the user pressing on the icon for the alert and moving the icon to the right. The user can either use a finger or a stylus. Optionally, e.g. in a desktop computer system, a mouse or a trackball could be used to drag the icon to the right. The speed and/or direction of the user input can thus be detected.
In a defer alert 684, the alert is deferred to reappear at a later time. The deferral time is calculated depending on the movement of the user input, e.g. using the speed of the movement of the user input when the icon is moved to the right or the angle at which the icon is moved to the right.
In a present new alert time step 686, the new alert is presented to the user. For example a text of the deferral time is shown on the display or a voice synthesizer reads the deferral time. The deferral time can be presented as a relative time, e.g. the alert is deferred 1 hour, or as an absolute time, e.g. the alert is deferred to 10:37.Optionally, date information can be added.
The whole process can be repeated several times for any message, alarm, etc., whenever an alert is presented.
FIGS. 7a-d illustrate schematic screen views of a user interface that can be embodied in the mobile terminal of FIG. 2.
In FIG. 7a, an alert is presented, comprising an icon 752 and a text alert 751 on a screen 750. In this example, a message has been received, whereby the icon 752 is depicted as an envelope. The text alert 751 is related to the alert in question. Optionally, no text alert 751 is presented.
In FIG. 7b, the user has selected the icon 752 and moves it in an orbital motion 767 to charge the alert with more energy, or momentum, by moving the icon 752 around and around, like when winding up a spring. The motion does not need to be circular, any rotational motion is sufficient.
In FIG. 7c, The user then flicks the icon 752 to the right towards a later action 754, to defer the alert. Depending on the momentum of the movement of the icon 752, which depends on the movement of the user input on the touch-sensitive display, the alert is deferred sooner or later. The momentum in this embodiment comprises the momentum built up during the orbital motion described above, and optionally the speed of the final movement of the icon 752. If the momentum is relatively low, the alert is deferred to a time soon in the future, e.g. in 15 minutes. On the other hand if the momentum is relatively high, the alert is deferred to a much later time, e.g. in two days. There are many other deferral times that can be determined between the 15 minutes and two days, corresponding to a momentum of the icon 752 between the momentum for 15 minutes and the momentum for 2 days.
Optionally, as shown in FIG. 7d, a text 760 is shown on the display indicating when the alert is deferred to. Alternatively or additionally, a voice synthesizer can generate an audio message indicating when the alert is deferred to.
Although the invention has above been described using an embodiment in a mobile terminal, the invention is applicable to any type of portable apparatus capable of presenting alerts, including pocket computers, portable mp3-players, portable gaming devices, cameras, lap-top computers, desktop computers etc.
The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
