For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the display unit 151 displays the photographed and / or received video or UI and GUI.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

Some of these displays may be transparent or light transmissive so that they can be seen through. This can be referred to as a transparent display, and a typical example of the transparent display is TOLED (Transparent OLED) and the like. The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see the object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another or may be disposed integrally with each other, or may be disposed on different surfaces.

Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen, It is an image that makes you feel the same as the space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means a parallax caused by the position of two eyes away from each other. When two eyes see two different images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt .

The stereoscopic display unit 152 may be applied to a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the autostereoscopic method include a parallax barrier method, a lenticular method, an integral imaging method, and a switchable lens method. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image).

In addition, the 3D thumbnail image can generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image and extracts a left image and a right image from the 3D image, or receives a 2D image and converts it into a left image and a right image.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

If 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects 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, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

In the case where the three-dimensional display unit 152 and the touch sensor have a mutual layer structure (hereinafter referred to as a 'three-dimensional touch screen') or a three-dimensional sensor that detects the touch operation and the stereoscopic display unit 152 are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144 as an example of the three-dimensional sensor.

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of light change, thereby acquiring position information of the object to be sensed.

The audio output module 153 can output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 153 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 153 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 154 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 154 may output a signal for notifying the occurrence of an event by using a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and pattern of the vibration generated by the hit module 155 can be controlled by the user's selection or setting of the control unit. For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

In addition to the vibration, the haptic module 155 may be configured to perform various functions such as a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or a suction force of the air through the injection port or the suction port, a touch on the skin surface, contact with an electrode, And various tactile effects such as an effect of reproducing a cold sensation using an endothermic or exothermic element can be generated.

The haptic module 155 can be implemented not only to transmit the tactile effect through the direct contact but also to allow the user to feel the tactile effect through the muscular sense of the finger or arm. At least two haptic modules 155 may be provided according to the configuration of the mobile terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

Once the fingerprint is recognized, the watch phone 301 finds a peripheral having a specific post-fix, automatically connects temporarily, and transmits the recognized fingerprint information as shown in FIG. 8C, After temporarily permitting automatic connection, determines whether the fingerprint received from the watch phone 301 and the directly recognized fingerprint are the same user's fingerprint. If the two fingerprints are judged to be the fingerprint of the same user, the connection is maintained, and if not, the connection is released.

In addition, the two fingerprints registered or recognized in the present invention do not necessarily have to be fingerprints of different fingers.

9 is an embodiment for performing information sharing between devices logging in to the cloud using fingerprint recognition. This embodiment is an embodiment in which content is shared via the cloud without direct connection between devices.

9, the user presses and holds the content (e.g., a picture) to be sent from the first device 400 and then presses and holds the screen of the second device 401 to which the content is to be sent next. The first and second devices 400 and 401 may be devices of the same type or other devices having a cloud account. The first and second devices (400, 401) simultaneously recognize the fingerprint of the user.

When the fingerprint recognition is completed, the first device 400 transmits (uploads) the fingerprint information, the content, and the crowd account information of the device user to the cloud, and the second device 401 transmits the fingerprint information and the cloud account of the device user to the cloud send.

The cloud 402 receiving the two pieces of fingerprint information determines whether the two fingerprints received from the first and second devices 400 and 401 are the fingerprint of one user or one of the accounts of the two devices is the first device user The user verification to check whether or not the content is authenticated and the usage form of the content.

If it is determined that the user of the first device 400 intends to share the content with the second device 401, the cloud 402 transmits the content uploaded from the first device 400 to the second device 401, And automatically deletes the content uploaded according to the security policy.

Therefore, even if the first and second devices 400 and 401 are not directly connected, the same content can be shared by performing downloading of contents through the cloud 400.

FIG. 10 is a flowchart illustrating a multi-device interworking method using a fingerprint according to an embodiment of the present invention.

As shown in FIG. 10, the present invention can register a fingerprint to be used in a multi-device connection with at least one smart device (S100). The fingerprints may register the same or different fingerprints for each device.

In the case where one fingerprint is registered, the registered fingerprint is scanned and registered in a device (first device) for providing content, and when two fingerprints are registered, 1 device) and the device (second device) receiving the content simultaneously recognize fingerprints sequentially, and all the recognized fingerprints are registered in the first device that provides the content.

When registering the one or two fingerprints, the present invention can provide different fingerprint registration guides. Different fingerprint registration guides may differ depending on the number of fingerprints registered. Further, the form of the fingerprint registration guide provided at the time of fingerprint registration can be determined by the time of touching or the number of touches when the device to be registered (second device) is selected.

Once the fingerprint registration is completed, the user displays the content on the first device (S110). The contents include music, photographs, images (moving images or still images), texts, and combinations thereof. The user selects the transmission mode of the content currently being displayed or reproduced on the first device (S120). The transmission mode is either shared or transmitted, and is selected through a dedicated button (a sharing button or a transmission button), respectively.

If the transmission mode is selected, the first device confirms the fingerprint authentication mode according to the time or number of times the dedicated button is pressed, and then provides a fingerprint recognition item and a fingerprint recognition guide. The fingerprint authentication mode is divided into a first authentication mode based on one fingerprint and a second authentication mode based on two fingerprints. That is, when the dedicated button is depressed for the first time by distinguishing the time to be touched, it is recognized as the first authentication mode, and when it exceeds the first time, it is recognized as the second authentication mode.

Further, the fingerprint authentication mode can be preset by the user in the first or second authentication mode in the menu.

The user inputs one fingerprint in the first device according to the first authentication mode or inputs the fingerprint simultaneously (or sequentially) in the first device and the second device according to the second authentication mode (S130). If the second device has previously been connected to the first device or is registered in the first device, the recognized fingerprint is immediately transmitted to the first device, and if it is not previously connected or registered (FIGS. 8A to 8C) A temporary connection is made to the first device in accordance with a postfix, and then the fingerprint is transmitted to the first device.

Therefore, when the first device is in the first authentication mode, the first device checks whether a fingerprint matching the recognized fingerprint is already registered. If the first fingerprint exists, the first device automatically connects to the second device registered in the fingerprint, (S140 to S160).

On the other hand, when the first device is in the second authentication mode, it is confirmed that the two fingerprints recognized are the fingerprints of the same user. If it is determined that the two fingerprints are the same user, the first device automatically connects to the second device, (S140 to S160).

As described above, the present invention is advantageous in that it can perform multi-device connection and information sharing more quickly by recognizing one or two fingerprints of a user and performing multi-device connection based on communication by communication have.

According to an embodiment of the present invention, the above-described method can be implemented as a computer-readable code on a medium on which a program is recorded.
