In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. For example, the function may include activation or deactivation of the display unit 151 or the touch pad 135.

The proximity sensor 141 described with reference to FIG. 1 will be described in more detail with reference to FIG. 4.

4 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger is close to the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

The distance at which the proximity signal is output when the pointer approaches the touch screen is called a detection distance. The proximity signal output from each proximity sensor is compared by using a plurality of proximity sensors having different detection distances. I can know the depth.

In FIG. 4, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors can also detect less than three or more than four proximity depths.

In detail, when the pointer is completely in contact with the touch screen (d0), the pointer is recognized as a touch. When the pointer is positioned below the distance d1 on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d1 or more and less than d2 on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the d2 distance by more than d3 distance on the touch screen, it is recognized as a proximity touch of a third proximity depth. In addition, when the pointer is located at a distance greater than or equal to d3 on the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity distance and the proximity position of the pointer touch screen, and perform various operation control according to the various input signals.

As shown in these figures, the mobile terminal 100 according to an embodiment of the present invention may include receiving channel information (CIA, CIB, CIC of FIG. 8) (S10).

The channel information (CIA, CIB, CIC in FIG. 8) is included in the header or tag of each channel (CN in FIG. 8), and is a portion indicating the attribute of each channel (CN in FIG. 8). The attributes of each channel (CN of FIG. 8) will be described in detail in the corresponding sections. The channel information (CIA, CIB, CIC of FIG. 8) may be obtained from a wireless network to which the mobile terminal 100 currently belongs, as shown in FIG.

FIG. 7 is a diagram illustrating a relationship between a location of a mobile terminal and a wireless network according to FIGS. 6A and 6B.

Each of the wireless networks A, B, and C may be Bluetooth for short range communication, Shared Wireless Access Protocol (SWAP), infrared communication (IrDA), Radio Frequency Identification (RFID), ZigBee, or the like. In addition, the wireless networks A, B, and C for each of the short range communication may communicate with the short range communication module 114 included in the mobile terminal 100.

Each of the wireless networks A, B, and C may have different areas covering each other, but may overlap each other in a predetermined area. Specifically, it means that the second and third wireless networks B and C may exist in the first wireless network A region covering a relatively wide area. In this case, a difference may occur in the wireless networks A, B, and C that can communicate through the local area communication module 114 according to the location of the mobile terminal 100.

That is, when the mobile terminal 100 is located at the first position P1, the mobile terminal 100 belongs only to the area of the first wireless network A, and thus the first channel (CNA of FIG. 8) transmitted by the first wireless network A is included. ) Can only be received. However, when the mobile terminal 100 moves to the second position P2, it is possible to receive the first and second channels (CNA and CNB of FIG. 8) originating from the first and second wireless networks A and B. When moving to the third position P3, all of the first, second, and third channels (CNA, CNB, CNC in FIG. 8) can be received. Meanwhile, although FIG. 7 illustrates the case where there are three wireless networks A, B, and C, the number of wireless networks A, B, and C is not limited thereto.

8 is a diagram schematically showing a channel according to an embodiment of the present invention, Figures 9a to 9 is a view showing a more specific configuration of each channel shown in FIG. As shown in these figures, each channel CN may include channel information CIA, CIB, CIC and channel bodies CBA, CBB, CBC.

The channel information CIA, CIB, CIC is an area indicating the attribute of each channel CN. That is, it means that the information contained in each channel CN includes information on which field. For example, the channel information (CIA, CIB, CIC) is the channel (CN) is a variety of information, such as weather information, traffic information, shopping information, advertising information, natural disaster information, lost child information, crime occurrence information, fire occurrence information It may include information indicating what kind of information is included in the.

When the first channel CNA is related to weather information, as shown in FIG. 9A, the first channel information CIA may include information for extracting a first keyword of “weather”. Meanwhile, the text information “weather” may be directly included in the first channel information CIA, and the first channel information CIA may be associated with the “weather” by using a predetermined symbol or number. It may also indicate that it contains information. When the second channel CNB is related to traffic information, as shown in FIG. 9B, the second channel information CNB may include information for extracting a 'second keyword' called 'traffic'. As illustrated in FIG. 9C, the third channel information CNC may include information for extracting a second keyword of “shopping”. 9A to 9C illustrate that one first keyword is included for convenience of description, but two or more first keywords related to each other may be included.

Channel bodies (CBA, CBB, CBC) are substantially areas containing information. Specifically, the first channel body CBA of the first channel CNA may include at least one content information CTI and a content CT corresponding to each of the content information CTI. That is, as shown in FIG. 9A, when the first channel CNA is a channel related to weather, the content information CTI included in the first channel body CBA is “Seoul”, “Suwon”, or the like. Each of these may be a 'third keyword'. On the other hand, as shown in Figure 9b, if the second channel (CNB) is a channel associated with traffic, the content information (CTI) included in the second channel body (CBB) may be "Sad", "Seocho", etc. Each of these may be a 'third keyword'. In addition, as shown in FIG. 9C, if the third channel (CNC) is a channel related to shopping, the content information (CTI) included in the third channel body (CBC) may be "homepage", "discount coupon", and the like. Each of these may be a 'third keyword'.

In step S10, when each channel information (CIA, CIB, CIC) is received in the channel (CN) transmitted from the wireless network (A, B, C) that can communicate at the current point where the mobile terminal 100 is located, In operation S20, the first keyword may be extracted from the channel information CIA, CIB, and CIC.

As described above, the first keyword is information such as "weather", "traffic", "shopping", etc. extracted from the channel information CIA, CIB, CIC indicating the attribute of each channel CN.

When the first keyword is extracted, the step S30 of determining whether the channel display condition is satisfied may proceed.

The user may wish that the channel is not displayed at a certain time such as a meeting time or bedtime or at a specific place such as a company or school. In this way, the condition for setting the channel not to be displayed at a specific time and place is the channel display condition. As shown in FIG. 10, the display unit 151 may display a channel search time setting menu M1 and a channel search place setting menu M1. Accordingly, the user can select a time and place where the channel search is to be performed.

If the channel display condition is not satisfied, step S40 may be performed to determine whether the received channel information corresponds to a specific channel.

Natural disaster information channel that informs the occurrence of natural disasters, such as the information channel for the occurrence of a missing child in a specific region, crime occurrence information channel to inform that a crime occurred, fire occurrence information channel to inform that a fire has occurred, In the case where the information for the public interest is large, the channel may be displayed even if it does not meet the channel display condition set by the user. That is, even when the user sets the channel search time from 10 to 18:00 as shown in FIG. 10, the information on the natural disaster information channel generated at 9:30 as shown in FIG. 11 is displayed. It means possible.

When the channel display condition is satisfied or the received channel information corresponds to a specific channel, a step (S50) of determining whether the extracted first keyword and the second keyword stored in the mobile terminal 100 are identical to each other may be performed. Can be.

The first keyword is information such as "weather", "traffic", "shopping", etc. extracted from channel information (CIA, CIB, CIC) indicating the attributes of each channel CN.

The second keyword is a keyword previously input and stored by the user. That is, when searching for a channel, information about what the user wants to know. A plurality of keywords may be inputted, or may be inputted in a form such as a higher concept-lower concept as necessary. That is, it is possible to input weather or region as a higher concept, and to input a region as a lower concept.

As shown in FIG. 12A, a first keyword extracted from channel information CIA, CIB, and CIC received in a specific region may be 'weather', 'traffic', or 'shopping'. In addition, the second keyword entered by the user may be 'shopping' or 'discount coupon'. In this case, when comparing the first keyword and the second keyword, it can be seen that the keywords 'shopping' coincide with each other.

When there are keywords that match each other by comparing the first and second keywords, a step (S60) of receiving and displaying a channel corresponding to the channel information from which the first keyword is extracted may be performed. On the other hand, as shown in Figure 6b, step S60 may include a step (S62) for extracting a third keyword from the content information (CTI).

As described above, the content information CTI may include specific keywords for the content CT included in each channel CN. Referring to FIG. 9C, the first keyword that may be extracted from the channel information CIC of the third channel CNC may be 'shopping'. On the other hand, the third channel (CNC) may include a content (CT) containing a website address and a content (CT) containing a discount coupon specifically. The header or tag portion of each content CT may include content information (CTI) indicating the characteristics of the information contained in each content (CT), and when the third keyword is extracted from the content information (CTI), Or 'discount coupon'.

When the third keyword is extracted, a step S64 may be performed to determine whether the third keyword and the second keyword coincide with each other.

That is, as shown in FIG. 12B, when the extracted third keyword includes 'homepage' and 'discount coupon', the second keyword stored by the user is compared with 'shopping' and 'discount coupon'. In this case, discount coupons can be coincident with each other.

If the third keyword and the second keyword coincide with each other, the step S66 of displaying the content corresponding to the third keyword may be performed.

When the third keyword after the first keyword coincides with the second keyword input by the user, the content CT of the channel CN is likely to be information that the user wants to receive. Accordingly, as shown in FIG. 13, the content corresponding to the content CT may be displayed on the display unit 151 so that the user can recognize and use the information.

14 is a flowchart illustrating a process of setting priorities of keywords in a mobile terminal according to an embodiment of the present invention, and FIGS. 15A and 15B are diagrams illustrating operations of the mobile terminal according to FIG. 14.

As shown in these figures, the process of setting priorities of the second keywords previously input to the mobile terminal may include displaying the input second keywords according to the current priority (S72).

That is, as illustrated in FIG. 15A, the second keywords previously input by the user may be displayed on the display unit 151. Each of the second keywords such as 'natural disaster', 'weather', 'transportation' and 'discount coupon' may be indicated by a current priority.

When the second keywords are displayed, step S74 of receiving a user's manipulation signal for each second keyword and changing the priority of the second keywords according to the input manipulation signal S76 may be performed.

The operation signal may be input through various user input units 130 provided in the mobile terminal 100, and specifically, may be input through a user's touch operation as shown in FIG. 15A. That is, the user selects a second keyword to change its priority and drags it upward or downward to change the priority of the second keyword as shown in FIG. 15B.

When the change of the priority is finished, the step S78 of storing the second keyword may be performed based on the changed priority. Therefore, if the priority is set, channels may be searched and displayed according to the priority in the future.

FIG. 16 illustrates a case where a channel is searched for and displayed based on the priority set by FIGS. 15A and 15B. That is, the channel may be displayed according to the priority set in FIG. 15B. Therefore, information of interest to the user may be displayed in a more visible position. In addition, when the priority is higher than a predetermined standard, it is also possible to call the user's attention by repeatedly outputting or generating a sound.
