[0045] FIG. 2 is a flowchart of a procedure of performing a sleep mode according to an embodiment of the present invention.

[0046] Referring to FIG. 2, in step 201, the processor 112 determines whether at least one of any preset conditions is satisfied. Step 201 will be described with reference to FIGS. 4 to 7.

[0047] If at least one of the preset conditions is satisfied, the processor 112 displays a corresponding icon in step 203. The at least one preset condition may be related to at least one of a connection to a charger, a time zone, a place, and ambient illumination. For example, regarding step 209, the at least one preset condition may be satisfied in at least one case where the charger is connected, where the current time belongs to a designated time zone, where the current location belongs to a designated place, and where the current ambient illumination is lower than a threshold. Step 209 will be described with reference to FIGS. 8 to 11.

[0048] In step 205, the processor 112 determines whether an icon touch event occurs. Such an event may be a touch operation on a single icon, multiple icons, etc. When the icon touch event occurs, the processor 112 sets the mode of the user device 100 to a sleep mode and performs the sleep mode, in step 207. The sleep mode is a function that may be used when a user does not want to be disturbed due to an alarm or sounds associated with functions generated by the user device 100. The processor 112 processes text messages, multimedia messages or calls by using user defined modes (silent, lamp, auto response) if text messages, multimedia messages or calls are received in the sleep mode.

[0049] In step 209, the processor 112 performs at least one function that is allowed in the sleep mode. The at least one function that is allowed in the sleep mode includes providing user customized information. The user customized information is daily life information on a field related directly to user daily life, and may include, among other things, information on how to or where to purchase food or daily supplies, information on various events, notice of power blackouts or cutting off water, weather forecasts, traffic information, etc. The user customized information may be obtained on the basis of a time, a place, and a schedule.

[0050] In step 211, the processor 112 again determines whether at least one of the preset conditions is not satisfied. For example, at least one of the preset conditions may not be satisfied in at least one case where a charger is disconnected, where the current time is not in a designated time zone, where the current location is not a designated place, and the current ambient illumination is higher than a threshold.

[0051] If at least one of the preset conditions is not satisfied, the processor cancels a sleep mode and cancels the at least one function performed in the sleep mode, in step 213.

[0052] On the other hand, if an icon touch event does not occur in step 205, the processor 112 determines whether a critical time duration has been exceeded, in step 215. If the critical time has not been exceeded, the processor 112 returns to step 205. On the contrary, if the critical time has been exceeded, the processor 112 releases an icon in step 217 and the process ends.

[0053] According to an embodiment of FIG. 2, if a user touches an icon, a sleep mode and at least one function that is allowed in the sleep mode are performed. Moreover, if at least one of the above-described preset conditions is satisfied, the processor 112 may automatically execute the sleep mode and the at least one function that is allowed in the sleep mode, without displaying an icon.

[0054] FIG. 3 is a flowchart related to step 201 of FIG. 2

[0055] Referring to FIG. 3, the processor 112 determines whether the user device is connected to a charger, in step 301.

[0056] If negative, the processor 112 ends this process. On the contrary, if it is determined that the user device is connected to the charger, the processor 112 determines whether the current time belongs to a preset time period, in step 303.

[0057] If the current time is not in the preset time period, the processor 112 ends this process. On the contrary, if the current time belongs to the preset time period, the processor 112 performs operations following step 203 described above.

[0058] A situation where the charger is connected to the user device 100 and the current time belongs to the preset time period (e.g., 11 PM to 4 AM) is an example of a situation where a user does not use the user device 100 or where the user is ready to sleep or is sleeping.

[0059] FIG. 4 is a flowchart related to step 201 of FIG. 2.

[0060] Referring to FIG. 4, the processor 112 determines whether the user device is connected to a charger, in step 401.

[0061] If negative, the processor 112 ends this process. On the contrary, if it is determined that the user device is connected to the charger, the processor 112 determines whether the user device 100 is currently located at a preset place, in step 403. The processor 112 may obtain location information from the GPS receiving unit 145 and make the determination by using the obtained location information where the user device 100 is located. For example, if a specific radius around the user's home is preset and the user device 100 enters the specific radius, the processor 112 determines the location of the user device 100 as the user's home.

[0062] If the current location is not the preset place, the processor 112 ends this process. On the contrary, if the current location belongs to the preset place, the processor 112 performs operations following step 203 described above. A situation where the charger is connected to the user device 100 and the user device 100 is located at the preset place (e.g., the user's home) is an example of a situation where a user does not use the user device 100 or where the user is ready to sleep or is sleeping.

[0063] FIG. 5 is a flowchart related to step 201 of FIG. 2.

[0064] Referring to FIG. 5, the processor 112 determines whether the user device is connected to a charger, in step 501.

[0065] If negative, the processor 112 ends this process. On the contrary, if it is determined that the user device is connected to the charger, the processor 112 determines whether ambient illumination is lower than a critical threshold, in step 503. The processor 112 obtains the ambient illumination from the sensor unit 140 and performs step 503 with the obtained ambient illumination.

[0066] If the ambient illumination is higher than the threshold, the processor 112 ends this process. On the contrary, if the ambient illumination is lower than the threshold, the processor 112 performs operations following step 203 described above. A situation where the charger is connected to the user device 100 and the ambient illumination is lower than the threshold is an example of a situation where a user does not use the user device 100 or where the user is ready to sleep or is sleeping.

[0067] FIG. 6 is a flowchart related to step 201 of FIG. 2.

[0068] Referring to FIG. 6, the processor 112 determines whether the current location belongs to a preset place, in step 601.

[0069] If negative, the processor 112 ends this process. On the contrary, if the current location belongs to the preset place, the processor 112 determines whether the current time belongs to a preset time period.

[0070] If the current time is not in the preset time period, the processor 112 ends this process. On the contrary, if the current time belongs to the preset time period, the processor 112 performs operations following step 203 described above. A situation where the current time belongs to the preset time period (e.g., 11 PM to 5 AM) and the user device 100 is located at the preset place (e.g., the user's home) is an example of a situation where a user does not use the user device 100 or where the user is ready to sleep or is sleeping.

[0071] FIG. 7 is a flowchart of the procedure of performing a sleep mode according to an embodiment of the present invention.

[0072] Referring to FIG. 7, the processor 112 determines whether the user device is connected to a charger, in step 701.

[0073] If negative, the processor 112 ends this process. On the contrary, if it is determined that the user device is connected to the charger, the processor 112 determines whether an alarm time arrives, in step 703.

[0074] If the alarm time does not arrive, the processor 112 ends this process. On the contrary, if the alarm time arrives, the processor 112 sets the mode of the user device 100 to a sleep mode and performs the sleep mode, in step 705. The sleep mode is a function that may be used when a user does not want to be disturbed. The processor 112 processes text messages, multimedia messages or calls by using user defined modes (silent, lamp, auto response) if the text messages, multimedia messages or calls are received in the sleep mode.

[0075] In step 707, the processor 112 performs at least one function that is allowed in the sleep mode. The at least one function that is allowed in the sleep mode includes providing user customized information. As described above, the user customized information is daily life information on a field related directly to user daily life, and may include information on how to or where to purchase food or daily supplies, information on various events, etc. The user customized information may be obtained on the basis of a time, a place, and a schedule. Step 707 will be described with reference to FIGS. 8 to 11.

[0076] In step 709, the processor 112 determines whether a charger is disconnected or whether a wakeup alarm (morning call) time arrives.

[0077] If the charger is connected or the wakeup alarm time does not arrive, the processor 112 maintains the sleep mode and the at least one function that is being performed. On the contrary, if the charger is disconnected or the wakeup alarm time arrives, the processor 112 cancels the sleep mode and the at least one function that is being performed in the sleep mode, in step 711.

[0078] FIG. 8 is a flowchart related to step 209 of FIG. 2 and step 707 of FIG. 7.

[0079] Referring to FIG. 8, the processor 112 obtains at least one piece of additional information that is related to a schedule, in step 801. The additional information is stored in the user device 100 or provided from an outside source such as a social network. The additional information is daily life information on a field related directly to user daily life, as described above.

[0080] In step 803, the processor 112 outputs the obtained at least one piece of additional information. The additional information is output through the touch screen unit 180 if it is a video type, and is output through the speaker 161 if the additional information is an audio type. Moreover, the processor 112 may also change a displayed text to sound through a text to speech (TTS) function and then output the sound through the speaker 161.

[0081] FIG. 9 is a flowchart related to step 209 of FIG. 2 and step 707 of FIG. 7.

[0082] Referring to FIG. 9, the processor 112 obtains at least one piece of additional information that is related to a schedule, in step 901. For example, a schedule that is registered for the next day may be organized as Table 1 below and its details are set to include items such as date and time, place, something to do, and participants.

	TABLE 1
			Something
	Date and time	Place	to do	Participants	. . .
Schedule	January 2,	Han-River	Baseball	TOM	. . .
	at 2 PM	Park

[0083] The processor 112 controls the user device so that the user device obtains additional information on at least one of “January 2, at 2 PM” of the item Date and time, “Han-River Park” of the item Place, “Baseball” of the item Something to do, and “TOM” of the item Participants, and additional information on two or more combinations thereof, and provides the obtained additional information. For example, the processor 112 determines the category of the schedule as an outdoor activity from “Han-River Park” of the item Place and “Baseball” of the item Something to do. The processor 112 obtains weather information on Han-River Park, January 2, at 2 PM from “January 2, at 2 PM” of the item Date and time and “Han-River Park” of the item Place. That is, the processor 112 obtains weather information related to an outdoor activity, and the weather information may be searched and obtained through the web.

[0084] In step 903, the processor 112 outputs the obtained at least one piece of additional information along with the schedule through an output unit (a display, a speaker, etc.). The additional information may be content that includes at least one of a text, an image, voice, music, a moving picture, and a Uniform Resource Locator (URL), and may be provided as a widget. For example, when the obtained weather information is “rain”, a rain image, rainfall, a temperature, relative humidity, wind, a comfort index, etc., are together displayed. Moreover, if the obtained weather information is “serenity”, a serenity image, a temperature, relative humidity, wind, a comfort index, etc., are together displayed. Moreover, the processor 112 may also display images that are captured from the Closed Circuit TeleVision (CCTV) that may be available at Han-River Park through a corresponding server.

[0085] In step 905, the processor 112 determines on the basis of the obtained at least one piece of additional information whether the schedule is suitable. That the schedule is suitable means that a user may easily perform the schedule, and on the contrary, that the schedule is unsuitable means that it may be difficult for the user to perform the schedule. For example, it may be determined on the basis of the weather information “rain” that an outdoor activity schedule is unsuitable, and thus the processor 112 determines that the schedule is unsuitable. Moreover, it may be determined on the basis of the weather information “serenity” that an outdoor activity schedule is suitable, and thus the processor 112 determines that the schedule is suitable.

[0086] When a schedule is suitable for the obtained at least one piece of additional information, the processor 112 outputs the details for the schedule and suitable matters in step 907. For example, the processor 112 determines on the basis of the weather information “serenity” that an outdoor activity schedule is suitable, and may output schedule details and the text or voice message “The weather is good for outdoor activities” as suitable matters. Moreover, the processor 112 may search a contact number related to “TOM” of the item Participants and also transmit to the searched contact number the suitable matter “The weather is good for outdoor activities” in a text or voice message.

[0087] When a schedule is unsuitable for the obtained at least one piece of additional information, the processor 112 outputs schedule details and unsuitable matters in step 909. For example, the processor 112 may determine on the basis of the weather information “rain” that an outdoor activity schedule is unsuitable, and outputs schedule details and the text or voice message “The weather is not good for outdoor activities” as unsuitable matters. Moreover, the processor 112 may search a contact number related to “TOM” of the item Participants and also transmit, to the searched contact number, the schedule and the above-described unsuitable matter “The weather is not good for outdoor activities” in a text or voice message.

[0088] In step 911, the processor 112 provides an event for schedule change or rearrangement. Such an event may include a text or voice message and induce a user to rearrange his/her schedule. The processor 112 searches, from the obtained at least one piece of addition information, recommendations capable of suitably correcting the unsuitable matter of the schedule, and outputs the searched recommendations. In the above-described example, the processor 112 outputs recommendations on a time period good for outdoor activities, day of the week, and place in a text or voice message. For example, the processor outputs a message that contains the recommendation “Weather at 4 PM is better than that at 2 PM for outdoor activities. Do you want to modify the schedule?”, and if a user accepts the modification, the schedule is automatically rearranged to reflect the recommendation. Moreover, the processor outputs a message that reflects the recommendation “Weather at 4 PM is good for outdoor activities. Do you want to inform participants?”, and if the user accepts it, this message is transmitted to the contact number of the participant “TOM”.

[0089] FIG. 10 is a flowchart related to step 911 of FIG. 9.

[0090] Referring to FIG. 10, in step 1003, the processor 112 searches a recommendation capable of correcting an unsuitable matter, from the obtained at least one piece of additional information. In the above-described example of FIG. 9, such a recommendation may be a time period suitable for outdoor activities, day of the week, a place, etc.

[0091] In step 1005, the processor 112 outputs at least one searched recommendation.

[0092] In step 1007, it is determined whether an event for applying the recommendation to the schedule occurs.

[0093] If the event occurs, the processor 112 applies the recommendation to the schedule in step 1009. That is, the schedule is changed or rearranged.

[0094] FIG. 11 is a flowchart related to step 801 of FIG. 8 and step 901 of FIG. 9.

[0095] Referring to FIG. 11, in step 1101, the processor 112 determines, on the basis of schedule details, at least one field or category to which a schedule belongs. Such a category may be an outdoor activity, an indoor activity, a variable place, etc.

[0096] In step 1103, the processor 112 obtains at least one piece of additional information that is related to the determined at least one category and schedule details. For example, when the category is the outdoor activity, weather information may be obtained on date and time, place, etc.

[0097] FIG. 12 is a screen of a user device according to an embodiment of the present invention.

[0098] Referring to FIG. 12, a plug connector 200 coupled to a cable end of a charger is electrically coupled to a socket connector of the user device 100. The user device 100 senses that the charger is connected, and then displays an icon 1201 that indicates a sleep mode. A user touches icon 1201 and the user device 100 executes the sleep mode and at least one function that is allowed in the sleep mode. However, if the icon 1201 is displayed and then an event where the icon 1201 is touched does not occur for a certain time, the icon 1201 is released.

[0099] FIGS. 13 to 20B are screens of a user device regarding a sleep mode according to an embodiment of the present invention.

[0100] Referring to FIG. 13, the user device 100 searches a schedule, and displays the searched schedule through a window 1301. Moreover, the user device 100 may output the searched schedule by voice through the speaker 161, and in this case the user device may change a displayed text to sound through a text-to-speech (TTS) function and then output the sound. Moreover, the user device 100 determines a category (e.g., an outdoor activity) to which a schedule belongs, obtains and displays additional information corresponding to the determined category.
