Mobile terminal and its operation method

The present invention relates to a mobile terminal and a method of operating the same, and more specifically, by displaying a 360 degree image in consideration of a user's intention, a viewer of the 360 degree image can easily grasp a user's intended area and quickly search for the corresponding area. It is to provide a mobile terminal and a method of operating the same.

Terminals may be divided into mobile / portable terminals and stationary terminals according to their mobility. The mobile terminal may be further classified into a handheld terminal and a vehicle mounted terminal according to whether a user can directly carry it.

The functions of mobile terminals are diversifying. For example, data and voice communication, image capturing and video recording through a camera, voice recording, music file playback through a speaker system, and outputting an image or video on a display unit are provided. Some terminals have an electronic game play function or a multimedia player function. In particular, recent mobile terminals can receive multicast signals that provide visual content such as broadcast and video or television programs.

Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. Detect.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

Meanwhile, the touch sensor and the proximity sensor described above may be independently or combined, and may be a short (or tap) touch, a long touch, a multi touch, a drag touch on a touch screen. ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. A touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, and the photo sensor may be configured to scan a movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents loaded on the photo sensor by using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

The stereoscopic display unit may be a three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glasses-free method), a projection method (holographic method).

Generally, a 3D stereoscopic image is composed of a left image (left eye image) and a right image (right eye image). A top-down method in which the left and right images are arranged up and down in one frame according to the way in which the left and right images are merged into three-dimensional stereoscopic images.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different air interfaces and / or physical layers. For example, a radio interface that can be used by a communication system includes frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (CDMA). ), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), etc. This may include.

Hereinafter, for convenience of description, the description will be limited to CDMA.

In addition, a satellite positioning system (Global Positioning System, GPS) for identifying the position of the mobile terminal 100 may be linked to the CDMA wireless communication system. The satellite helps to locate the mobile terminal 100. Useful location information may be obtained by up to two or more satellites. Here, the location of the mobile terminal 100 may be tracked using all the technologies capable of tracking the location as well as the GPS tracking technology. In addition, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 provided in the mobile terminal is used to detect, calculate, or identify the location of the mobile terminal. Examples of the location information module 115 may include a Global Position System (GPS) module and a Wireless Fidelity (WiFi) module. If necessary, the location information module 115 may perform any function of other modules of the wireless communication unit 110 to substitute or additionally obtain data regarding the location of the mobile terminal.

The GPS module 115 calculates distance information and accurate time information away from three or more satellites, and then applies trigonometry to the calculated information, thereby accurately calculating three-dimensional current position information according to latitude, longitude, and altitude. can do. Currently, a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 may calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal using the GPS module in the shadowed area of the satellite signal such as indoors. Accordingly, in order to compensate for GPS positioning, a WPS (WiFi Positioning System) may be utilized.

The Wi-Fi Positioning System (WPS) uses a WiFi module provided in the mobile terminal 100 and a wireless access point (AP) for transmitting or receiving a wireless signal with the WiFi module. As a technology for tracking the location of a, it refers to a WLAN (Wireless Local Area Network) based location positioning technology using WiFi.

In this case, in order to remove the wireless AP provided by the mobile AP or the illegal MAC address in the positioning process in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in the order of high RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one piece of wireless AP information extracted from a database. The location information of the mobile terminal 100 is extracted (or analyzed) by comparing the included information with the received wireless AP information.

As a method for extracting (or analyzing) the location information of the mobile terminal 100, a cell-ID method, a finger print method, a triangulation method, a landmark method, or the like may be utilized.

The Cell-ID method is a method of determining the location of a mobile AP having the strongest signal strength among neighboring wireless AP information collected by the mobile terminal.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and the use of reflected light may be different from that of a conventional flat panel display. Electronic paper can change information using twisted balls or electrophoresis using capsules.

In a state where the flexible display unit 251 is not deformed (for example, a state having an infinite curvature radius, hereinafter referred to as a first state), the display area of the flexible display unit 251 is flat. In the state deformed by the external force in the first state (for example, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, the information displayed in the second state may be visual information output on a curved surface. Such visual information is implemented by independently controlling light emission of a sub-pixel disposed in a matrix form. The unit pixel refers to a minimum unit for implementing one color.

In addition, due to the bending of the flexible display unit 251 may be a variety of information that can be detected.

In addition, the controller 180 changes the information displayed on the flexible display unit 251 or changes the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251 detected by the deformation detecting means. It can generate a control signal for controlling the function of.

Meanwhile, the mobile terminal 200 according to the present modified example may include a case 201 for accommodating the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of characteristics of the flexible display unit 251.

In addition, the battery (not shown) included in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked up may be applied.

In detail, when a drag signal from an area frequently watched by a user to another area is input, the mobile terminal 100 may slowly move an area frequently watched by the user. By this, switching to another area is performed slowly.

As shown in FIG. 11B, a drag signal is input to another area while the area where the user 601 wearing the bridesmaid costume appears appears. The currently displayed area is an area frequently viewed by the user. Therefore, the mobile terminal 100 slowly moves the corresponding area. From this, the user can intuitively recognize that the area is an important area in which the user's intention is reflected. As a result, regardless of the drag speed input, switching from the area viewed by the user to another area may be performed slowly.

11C illustrates a case where a user searches from an area not frequently viewed by a user to another area. In detail, when a drag signal is input from an area not frequently watched by the user to another area, the mobile terminal 100 may quickly move an area not frequently watched by the user. That is, when the user passes a region not frequently viewed by the drag signal, the mobile terminal 100 may move the region at a high speed. By this, switching to another area is performed quickly.

As shown in FIG. 11C, a drag signal to another area is input while the area where the groom and the bride appear is displayed. The currently displayed area is an area that the user has not viewed much. Therefore, the mobile terminal 100 moves the area quickly. From this, the user can intuitively recognize that the area is not an important area in which the user's intention is reflected. Thereby, regardless of the dragging speed input, switching from the area where the user does not watch much to another area can be performed quickly.

According to another embodiment, when a drag signal for searching the 360 degree image 600 is input, the mobile terminal 100 is currently displayed in a direction in which an area viewed by a user exists, regardless of the direction of the drag signal. You can move the area. As a result, switching to the area viewed by the user much is quickly performed. In FIG. 11C, if the area where the user's fiancé 602 appears is the area that the user watched a lot, and the area where the user 601 wearing the bridesmaid costume appears is the area that the user skips frequently, Even if a search signal moving in the left direction is received, the mobile terminal 100 may switch the area in the right direction on the current screen. Thereby, the switching to the area viewed by the user much can be performed quickly regardless of the dragging direction.

As described above, according to the exemplary embodiment illustrated in FIGS. 11A to 11C, in a three-dimensional 360 degree image having a wide range, a user may easily and quickly access a portion of an image that he / she wants to watch.

FIG. 12A illustrates an image displayed first when the viewer plays the 360 degree image 600.

In this case, the other party or the third party may play the 360 degree image 600 shared through the mobile terminal 100.

The user's viewing record is stored in the 360 degree image 600. Therefore, when the mobile terminal 100 plays the 360 degree image 600, the mobile terminal 100 may first display an area viewed by the user with reference to the user's viewing record. As a result, the 360-degree image 600 may be started at the portion viewed by the user the most.

The other party or the third party may watch the image of the part which the user most viewed, and may determine the user's intention based on this.

In FIG. 12A, the 360-degree image 600 begins in an area where a user 601 wearing a bridesmaid costume appears. From this, the other party or the third party can recognize that the intention of the bridesmaid costume is displayed.

12B illustrates a case where the other party searches to find the area intended by the user. The other party may search the entire area of the 360 degree image 600 to find the fiance 602 of the user in the 360 degree image 600. In this case, according to the conventional method of searching for the 360 degree image 600, the other party must search the fiancé 602 of the user by searching the entire area of the 360 degree image 600. Since the entire area of the 360-degree image 600 is extensive, the counterpart cannot easily find the fiance 602 of the user.

FIG. 12C illustrates a case in which the moving speed is displayed differently for each area when the other party searches for a 360 degree image. When the 360 degree image 600 is searched, the mobile terminal 100 may move each of the entire areas of the 360 degree image 600 at different speeds. Specifically, the mobile terminal 100 allows the user to watch the area that is frequently watched, and moves the area where the user does not watch much. In this case, the area frequently watched by the user may be set based on the number of times and / or viewing time of the user.

According to this, the mobile terminal 100 does not move the entire area of the 360 degree image 600 at the same speed in response to the search signal. That is, when the mobile terminal 100 searches for the 360 degree image 600 in response to the search signal, the mobile terminal 100 may apply the moving speed differently according to the degree of the user's viewing of each of the entire areas of the 360 degree image 600. have.

Referring to FIG. 12C, the entire area of the 360 degree image 600 is searched as follows. The most watched area by the user is the area where the user 601 wearing the bridesmaid costume appears and the area where the user's fiancé 602 appears. Therefore, when a signal for searching for these areas is input, the mobile terminal 100 slowly moves the corresponding areas. Since the area where the groom and the bride appear is an area that a user sometimes watches, the mobile terminal 100 moves the area at a normal speed. On the other hand, areas in which no characters appear and only the background screen is displayed are areas that the user rarely watched or skipped frequently. Therefore, when a signal for searching for a corresponding area is input, the mobile terminal 100 quickly moves the corresponding area.

In FIG. 12C, even when the other party performs a drag operation near the region where the fiance 602 of the user appears, the corresponding image is slowly passed. From this, the other party can recognize that the video is an important part. Thus, the other party can quickly find the fiance 602 of the user in an intuitive manner.

13A illustrates a case of setting blind processing on a 360 degree image. The mobile terminal 100 may set blind processing on the 360 degree image in response to the input signal. The blind process may be an image process that prevents the viewer from recognizing a predetermined region of the 360 degree image. In detail, the mobile terminal 100 may set security on a predetermined area of the 360 degree image, set an obstruction, fade the area, skip the area, or move the area quickly. In addition, the mobile terminal 100 may perform a combination of a plurality of such image processing. According to this, the user can blindly share an area that he or she has dragged over or an area that he does not want to be exposed to and shared with the other party or a third party.

Referring to FIG. 13A, a user selects an edited image 1310 of a predetermined 360 degree image on an execution screen of a gallery application. In detail, when an input signal for long pressing the edited video 1310 is input, the mobile terminal 100 may perform blind processing on the edited video 1310.
