To illustrate. When the battery 191 is detachably configured to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

An accessory may be added to the mobile terminal 100 to protect the appearance or to assist or expand the function of the mobile terminal 100. An example of such an accessory may be a cover or pouch that covers or accommodates at least one surface of the mobile terminal 100. The cover or pouch may be configured to be linked with the display unit 151 to expand the function of the mobile terminal 100. Another example of the accessory may be a touch pen for assisting or extending a touch input to a touch screen.

On the other hand, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the user mainly holding in the hand. Such wearable devices include a smart watch, a smart glass, a head mounted display (HMD), and the like. Hereinafter, examples of the mobile terminal extended to the wearable device will be described.

The wearable device may be configured to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 may detect (or recognize) a wearable device that can communicate around the mobile terminal 100. In addition, when the detected wearable device is a device that is authenticated to communicate with the mobile terminal 100, the controller 180 transmits at least a portion of data processed by the mobile terminal 100 through the short range communication module 114. Can be sent to. Therefore, the user may use data processed by the mobile terminal 100 through the wearable device. For example, when a call is received by the mobile terminal 100, a phone call may be performed through the wearable device, or when the message is received by the mobile terminal 100, the received message may be confirmed through the wearable device. .

Glass-type mobile terminal 200 is configured to be worn on the head of the human body, it may be provided with a frame portion (case, housing, etc.) for this. The frame portion may be formed of a flexible material to facilitate wearing. In the drawing, the frame part includes a first frame 201 and a second frame 202 of different materials. In general, the mobile terminal 200 may include the features of the mobile terminal 100 of FIGS. 1A-1C or similar features.

The frame part is supported by the head, and provides a space for mounting various components. As illustrated, electronic components such as the control module 280, the sound output module 252, and the like may be mounted in the frame unit. In addition, a lens 203 covering at least one of the left eye and the right eye may be detachably mounted to the frame unit.

The control module 280 is configured to control various electronic components provided in the mobile terminal 200. The control module 280 may be understood as a configuration corresponding to the controller 180 described above. In this figure, the control module 280 is illustrated to be installed in the frame portion on one side head. However, the position of the control module 280 is not limited thereto.

The display unit 251 may be implemented in the form of a head mounted display (HMD). The HMD type is a display method mounted on the head and showing an image directly in front of the user's eyes. When the user wears the glass type mobile terminal 200, the display unit 251 may be disposed to correspond to at least one of the left eye and the right eye so as to provide an image directly in front of the user's eyes. In this drawing, the display unit 251 is positioned at a portion corresponding to the right eye so that an image can be output toward the right eye of the user.

The display unit 251 may project an image to the eyes of a user using a prism. In addition, the prism can be formed translucent so that the user can see the projected image together with the general field of view (the range the user sees through the eye) together.

As such, the image output through the display unit 251 may be seen to overlap with the general field of view. The mobile terminal 200 may provide an augmented reality (AR) that displays a single image by superimposing a virtual image on a real image or a background using the characteristics of the display.

The camera 221 is disposed adjacent to at least one of the left eye and the right eye, and is formed to capture an image of the front. Since the camera 221 is located adjacent to the eye, the camera 221 may acquire a scene viewed by the user as an image.

In this drawing, the camera 221 is illustrated in the control module 280, but is not necessarily limited thereto. The camera 221 may be installed in the frame portion, or may be provided in plural to acquire a stereoscopic image.

The glass type mobile terminal 200 may include user input units 223a and 223b that are manipulated to receive a control command. The user input units 223a and 223b may be adopted in any manner as long as the user is operating in a tactile manner such as touch or push. In the drawing, the frame unit and the control module 280 are provided with push and touch input user input units 223a and 223b, respectively.

In addition, the glass-type mobile terminal 200 may be provided with a microphone (not shown) for receiving sound and processing it as electrical voice data and a sound output module 252 for outputting sound. The sound output module 252 may be configured to transmit sound in a general sound output method or a bone conduction method. When the sound output module 252 is implemented in a bone conduction manner, when the user wears the mobile terminal 200, the sound output module 252 is in close contact with the head and vibrates the skull to transmit sound.

The mobile terminal according to the present invention analyzes an image input through a camera and provides appropriate information according to a situation in which the user is placed. For example, when analyzing a video input through a camera, if a bus stop is recognized, the mobile terminal may output bus arrival time information at the corresponding bus stop. As another example, when analyzing a video input through the camera, if the movie ticketing machine is recognized, the mobile terminal may output the movie timetable information in the theater.

As described above, the mobile terminal according to the present invention may recognize an object in an image input through a camera and output information corresponding to the recognized object.

However, if the user always keeps the camera on in order to provide information suitable for the user's situation, the battery of the mobile terminal will be discharged quickly. Accordingly, when it is desired to provide information suitable for a user's situation through a camera, it is necessary to provide a method for reducing power consumption of the mobile terminal.

To this end, the mobile terminal according to the present invention maintains the camera in the off state normally, or controls the camera to be turned on temporarily for a long time period (called a first time period), while a predetermined condition is satisfied. When the camera is turned on for a predetermined time, the camera may be controlled to be turned on for a short time every short time period (called a second time period).

To this end, it is assumed that the mobile terminal according to the present invention includes a wireless communication unit, a camera, a display unit, a memory, and a control unit among the components shown in FIG. 1.

The mobile terminal according to the present invention may function as an auxiliary device for assisting another device, or operate as a main device receiving assistance from the auxiliary device. For example, the mobile terminal may be used as a main device for receiving a call signal or a text message directly from a base station, or when another device receives a call signal or a text message, the call signal or text message received by the other device. It may be used as an auxiliary device for outputting information about the back.

When the mobile terminal is used as a periodic device, the controller may directly receive an image captured by the auxiliary device from the auxiliary device while directly executing an application installed in the memory. On the other hand, when the mobile terminal is used as an auxiliary device, the mobile terminal may transmit an image captured by the camera to the main device or output information received from the main device through the display unit at the request of the main device. The secondary device and the main device can communicate through a communication scheme such as Bluetooth, NFC, Wi-Fi, and Wi-Fi Direct.

For convenience of description, in the following embodiments, it is assumed that the main device is a bar type smart phone and the auxiliary device is a glass type terminal. However, embodiments described later may be applied to other various types of mobile terminals. For example, a glass-type device may be used as a main device, while a bar-type device may be used as an auxiliary device, and wearable devices such as a necklace type, a watch type, a ring type, a folding type, a swing type, and the like. It will be appreciated that the device may operate as a primary device or an auxiliary device.

However, when a glass-type or necklace-type device is used as an auxiliary device, it is highly likely that the user's gaze and the camera photographing direction coincide with each other. Side effects may occur.

In the following embodiments, the functions of the main device and the auxiliary device will be described separately. Specifically, it will be described that the main device serves to drive an application, and the auxiliary device serves to provide an image captured by the camera to the main device.

However, the roles of the main device and the auxiliary device to be described later may be integrated in one device. As an example, the mobile terminal according to the present invention may analyze the image photographed by the camera while executing an application and output information suitable for a situation in which the user is placed. That is, in the embodiments described below, if a communication process between the main device and the auxiliary device is omitted and considered, it will be apparent to those skilled in the art that embodiments to be described below may be performed through one mobile terminal. . In addition, not only the main device and the auxiliary device described below, but also a mobile terminal incorporating the roles of the main device and the auxiliary device into one will be considered to belong to the scope of the present invention claims.

Based on the above description, the present invention will be described in detail.

In the main device, when the application is executed (S301), the main device may transmit execution information indicating that the application has been executed to the auxiliary device (S302). Here, the execution information may include the name of the application, whether the application supports camera analysis, and the like. The primary device may transmit a signal requesting the secondary device to wake up the camera every first time period together with the execution information.

If the application executed on the primary device is an application that provides information suitable for the user's situation through camera analysis, or if the primary device receives a signal requesting an intermittent wake up of the camera, the secondary device May wake up every first time period and control to photograph the surroundings (S303). In detail, the controller of the auxiliary device wakes up every first time period, controls the camera to photograph the surroundings for a predetermined time, and then transmits the image captured by the camera to another device. In this case, the image photographed by the camera waking up every first time period may be a moving image or at least one still cut.

Even if the application executed in the main device is an application that provides information suitable for the user's situation through camera analysis, the auxiliary device may keep the camera off until the predetermined condition is satisfied.

The controller of the auxiliary device may transmit an image captured by the camera to the main device. The controller of the main device may provide information suitable for a situation in which the user is placed through image analysis received from the auxiliary device.

In a state where the application is running through the main device, when the controller of the main device recognizes that a predetermined condition is satisfied (S304), the controller of the main device signals to the auxiliary device to change the wake-up period of the camera. It may be transmitted (S305). Then, the controller of the auxiliary device may control the camera to wake up every second time period, which is shorter than the first time period, to photograph the surroundings (S306).

If the camera of the auxiliary device is in the OFF state, the controller of the auxiliary device controls the camera to wake up every predetermined time period and photograph the surroundings in response to the request signal received from the main device, or the camera for a predetermined time or more. Can be controlled to remain On.

Here, the wake-up period of the camera may be a time until the next On state after the camera is turned on, or a time until the On state after the camera is turned off It may be. In addition, the time that the camera maintains the On state may be fixed or may vary for each wake-up period. For example, the controller of the auxiliary device controls the camera to remain On for 1 second when the camera is set to wake up every first time period, and when the camera is set to wake up every second time period, the camera 2 Can be controlled to stay On for seconds.

As the wake-up cycle of the camera becomes shorter, the secondary device will be able to transmit captured images to the primary device more often.

In FIG. 3, it is shown that the controller of the main device determines whether a predetermined condition is satisfied. Unlike the example illustrated in FIG. 3, the controller of the auxiliary device may determine whether a predetermined condition is satisfied. In this case, the process of transmitting the request signal from the primary device to the secondary device may be omitted.

Whether the predetermined condition is satisfied includes pattern information accumulated for a predetermined period, a moving speed of a user (ie, a mobile terminal or another device), a path that the user (ie, a mobile terminal or another device) has moved, a card usage information, and a present time. The location may be determined based on the location, the signal generated by the sensing unit, the number of steps of the user, and the presence or absence of a predetermined object in the image captured by the camera.

Although not shown, when the control unit of the main device recognizes that a predetermined condition is satisfied while the second time period is being applied, the control unit of the main device requests the auxiliary device to change the wake-up period of the camera. You can send a signal. Then, the controller of the auxiliary device may control the camera to wake up every first time period.

As another example, the controller of the auxiliary device may control the camera to be turned off again in response to the request signal received from the main device.

When the application is terminated in the primary device (S307), the primary device may transmit termination information indicating that the application is terminated to the secondary device (S308). Then, the controller of the auxiliary device may switch the camera to the off state (S309). That is, the auxiliary device can control the camera to remain in the ON state only while the application is running in the main device.

As described above, the auxiliary device may transmit an image captured by the camera to the main device while the application is being executed through the main device. Then, the main device can recognize the situation placed by the user through the analysis of the image taken by the camera and can provide the appropriate information to the user.

Hereinafter, the present invention will be described in more detail with reference to specific examples applicable to the present invention.

Example 1-Providing Traffic Information

The mobile terminal according to the present invention can be used to provide traffic information to a user. 4, the example of providing traffic information will be described in detail.

4 is a diagram illustrating an example in which traffic information is output. For convenience of explanation, it is assumed that the main device is running an application for providing traffic information (for example, an application for notifying a bus arrival time of each stop or an application for notifying a subway arrival time). do. Even when the traffic information providing application is executed in the background state, the following embodiments may be applied.

If the application is running through the main device, the controller of the auxiliary device may control the camera to wake up every first time period (S401). In addition, the controller of the auxiliary device may transmit an image captured by the camera to the main device (S402). As described above, if the auxiliary device is a glass type device, the camera will photograph the same direction as the user's gaze.

When the captured image is received from the auxiliary device, the controller may analyze the captured image to determine whether the first object or the second object is included in the captured image. Here, the first object may be for adjusting a wake-up period of the auxiliary device camera, and the second object may be for outputting information suitable for a situation in which the user is placed.

When the first object is found through the camera, or pattern information accumulated for a predetermined period of time, the moving speed of the user (ie, the mobile terminal or another device), the path that the user (ie, the mobile terminal or other device) has moved, and the card When it is determined that the predetermined condition is satisfied in consideration of the usage information, the current location, the signal generated by the sensing unit, or the number of steps of the user (S403), the controller of the main device may change the wakeup period of the camera to the auxiliary device. Can request (S404).

When the request signal is received from the main device, the controller of the auxiliary device may control the camera to wake up every second time period shorter than the first time period (S405). As the wake-up cycle of the camera is shortened, the auxiliary device may transmit the captured image more frequently to the main device (S406).

When the second object is found from the captured image received from the auxiliary device or when the predetermined condition is satisfied together with the second object (S407), the controller of the main device may output information necessary for the user (S408). In this case, the controller of the main device may transmit information necessary for the user to the auxiliary device, and control the information to be output through the auxiliary device. Some of the information necessary for the user may be output through the auxiliary device, and the rest of the main device may be output. You can also control the output.

In the example shown in FIG. 5, the wake-up period of the camera is shortened when the user arrives at the bus stop or when the user approaches the subway station.

The operation of the main device and the auxiliary device for each section will be described in detail by dividing the graph shown in FIG. 5 into a plurality of sections. In Fig. 5, numbers written in circles indicate numbers identifying each section.

First section

When the user moves from the home to the bus stop while the traffic information application is running through the main device, the camera of the auxiliary device may wake up and take a picture every first wake-up period.

The controller of the main device may move the user to the bus stop based on the speed at which the user walks, the path of the user's current time zone, the current location, the analysis of the captured image received from the auxiliary device, or the detection signal of the sensor unit. It can be recognized that there is.

For example, if the behavior of moving from the home to the bus stop is repeated during the predetermined time period, the controller of the main device may store the morning time user moving to the bus stop as pattern information. The pattern information may include information such as a path that the user takes to move to the bus stop, information on an average pace of the user, a landmark on the moving path to the bus stop, and the like.

On the basis of the pattern information, if the user is moving to the bus stop but is still determined to be at least a predetermined distance from the bus stop, or more than a predetermined time is left until the bus stop arrives, the control unit of the main apparatus provides assistance. The camera of the device may be controlled to wake up every first wake-up period.

The controller of the main device may calculate whether the user is away from the bus stop by a predetermined distance or more, or more than a predetermined time remaining before arriving at the bus stop, based on the location of the main device or the speed of the user's walking.

2nd section

In the captured image received from the auxiliary device, a landmark on the travel path to the bus stop is found, or if the position of the main device is located within the first reference distance from the bus stop, or the remaining time until reaching the bus stop is displayed. If less than the first reference time, the controller of the main device may request the auxiliary device to change the wake up period of the camera.

For example, when a user crosses a path on a route when the user moves to a bus stop, the controller of the main device may return to the auxiliary device when the crosswalk is recognized from the captured image received from the auxiliary device. A signal may be transmitted requesting that the camera wake up period be changed.

At this time, the control unit of the main device is located within the first reference distance from the bus stop in order to prevent the camera wake-up period is shortened when a crosswalk other than the crosswalk around the bus stop is recognized. If the pedestrian crossing is found or when the remaining time until reaching the bus stop is less than or equal to the first reference time, the auxiliary device may request to change the wake-up cycle of the camera.

When the request signal is received from the primary device, the secondary device may change the wake up period of the camera. In detail, the controller of the auxiliary device may change the wake-up period of the camera from the first time period t1 to the second time period t2.

In this case, the controller of the auxiliary device may control the wakeup period of the camera to be immediately changed from the first time period to the second time period. However, as in the example illustrated in FIG. 5, the wakeup period of the camera is the first time. It may also be controlled to become a second time period which gradually shortens from the period and eventually reaches the end. In this case, the controller of the auxiliary device adjusts the wake-up period of the camera gradually toward the second time period as the position of the auxiliary device (or the main device) is closer to the bus stop or the remaining time until the bus stop arrives. Can be controlled.

3rd section

When a landmark that can be recognized as a bus stop is found in the captured image received from the auxiliary device, or when the main device is located within a second reference distance shorter than the first reference distance from the bus stop, or arrives at the bus stop. When the remaining time is less than or equal to the second reference distance shorter than the first reference time, the controller of the main device may output bus arrival time information at the corresponding bus stop.

For example, when a user arrives at a bus stop, the signs installed at the bus stop are stored as pattern information (for example, when the user arrives at the bus stop, a sign in the image received through the camera of the auxiliary device is found. If a case is accumulated more than a predetermined number (or ratio) in a predetermined period of time, the controller of the main device may control to output the bus arrival time information at the corresponding bus stop when a sign is recognized from the captured image received from the auxiliary device. Can be.

In this case, the bus arrival time information may be output from only one of the main device and the auxiliary device, or may be output from both the main device and the auxiliary device.

As in the example illustrated in FIG. 6A, the controller of the main device 10 may transmit information about the arrival time of the bus expected to be boarded by the user from the bus arrival time information through the auxiliary device 20. You can control the output.

At this time, the controller of the main device 10 predicts the bus number expected to be boarded by the user by analyzing the image input through the camera immediately before the user is recognized as boarding the bus for a predetermined period of time. can do. As another example, the control unit of the main device 10 stores the destination when the user boarded the bus as pattern information for a predetermined period of time, and then the bus that the user is expected to board the buses traveling to the destination. Can also be considered.

The controller of the main device 10 may output some of the bus arrival time information through the auxiliary device 20, and may output the remaining information through the main device 10. For example, in FIG. 6A, any one arrival time information 610 that is expected to have the fastest arrival time among buses that are expected to be boarded by the user is displayed through the display unit of the auxiliary device 20. It is illustrated that the arrival time information of the buses expected to be boarded by the user and the expected arrival time information 620 to the destination are output through the main device 10.

When bus arrival time information is output not only in the auxiliary device 20 but also in the main device 10, the control unit of the auxiliary device 20 may control the main device 10 as in the example illustrated in FIG. 6A. ) May be controlled to output an indicator 615 indicating that bus arrival time information is being output.

The bus arrival time information output through at least one of the main device 10 and the auxiliary device 20 may be received from a server associated with the traffic information application.

When the remaining time until the arrival time of the bus to be boarded by the user is less than a predetermined time, or when the user's eyes do not look in the direction in which the bus should arrive (for example, an image input through the camera is displayed as a main device ( 10), or when the user is using another application (for example, during a call or playing a game) through the main device 10, the main device 10 is connected to the auxiliary device 20. ) Can be controlled to output a notification that the bus is about to arrive.

Specifically, through the auxiliary device 20, as shown in the example of FIG. 6B, a message 620 indicating that the vehicle will arrive soon may be output. The controller of the auxiliary device 20 may output a vibration, a sound, and the like together with a message.

When the bus to be boarded by the user is recognized in the image received through the auxiliary device 20, the controller of the main device 10 may control to output a notification for guiding a bus ride through the auxiliary device 20. .

In detail, as shown in the example of FIG. 6C, the auxiliary device 20 may output a message 630 indicating that the bus has arrived. The controller of the auxiliary device 20 may output a vibration or a sound together with a message.

In FIGS. 6B and 6C, the notification is output from the auxiliary device 20, but the notification may be output from the main device 10.

4th section

If it is determined that the user boarded the bus, the main device may request the auxiliary device to change the wake-up cycle of the camera. Specifically, when the image input through the camera is taken inside the bus, when the bus fee is paid through the card registered in the main device or when the gyro sensor or the acceleration sensor, etc. boards the bus, the same shaking or acceleration In the case of detecting the primary device, the primary device may request the secondary device to change the wake-up cycle of the camera.

When the request signal is received from the primary device, the secondary device may change the wake up period of the camera. In detail, the controller of the auxiliary device may control the wakeup period of the camera to be changed from the second time period back to the first time period.

In this case, the controller of the auxiliary device may control the wakeup period of the camera to be immediately changed from the second time period to the first time period. However, as in the example illustrated in FIG. 5, the wakeup period of the camera is set to the second time. It may be controlled so as to become a first time period gradually gradually reaching from the period to the end.

5th section

While the user is boarding the bus, an image of the inside of the bus will be input through the camera. Since it is difficult to find a special object for grasping the user's situation through the image of the inside of the bus, it is preferable to set a long wake-up cycle of the camera while the user is on the bus.

Accordingly, the controller of the auxiliary device may control the wakeup period of the camera to maintain the first time period while the user is boarding the bus.

6th section

If it is determined that the user got off the bus and the user's pattern information is considered, and the user is expected to transfer to a second means of transportation (for example, a subway) after getting off the bus, the control unit of the main apparatus is a subsidiary device. May request to change the wake-up cycle.

For example, when the main device detects an image outside the bus through a captured image received from an auxiliary device, when the bus disembarkation information is received through a card registered to the main device, or a gyro sensor or an acceleration sensor boards the bus. In the case of no longer detecting the shaking or the acceleration as in the case of the above, the controller of the main device may determine that the user got off the bus. In addition, during the predetermined time period, in the morning time zone, if the act of getting off the bus at the same place is repeated, the control unit of the main device determines that the user is on the bus It may be judged that it got off.

During the predetermined period, if the action of moving to the subway station is repeated after getting off the bus, the controller of the main device may store the moving to the subway station as pattern information after getting off at the bus stop of the predetermined position.

In view of the pattern information, since the user is expected to move to the subway station after getting off the bus, the controller of the main device may request the auxiliary device to change the wake-up period of the camera.

When the request signal is received from the primary device, the secondary device may change the wake up period of the camera. In detail, the controller of the auxiliary device may change the wake-up period of the camera from the first time period to the second time period.

In this case, the controller of the auxiliary device may control the wakeup period of the camera to be immediately changed from the first time period to the second time period. However, as in the example illustrated in FIG. 5, the wakeup period of the camera is the first time. It may also be controlled to become a second time period which gradually shortens from the period and eventually reaches the end. In this case, the controller of the auxiliary device controls the wake-up period of the camera to be gradually adjusted toward the second time period as the position of the auxiliary device (or the main device) is closer to the subway station or the remaining time until the subway station is shortened. can do.

7th section

When a landmark that can be recognized as a ticket gate or a platform is found in the captured image received from the auxiliary device, or the location of the main device is located within a second reference distance shorter than the first reference distance from the subway station, or arrives at the subway station When the remaining time is less than or equal to the second reference distance shorter than the first reference time, the controller of the main device may output subway arrival time information at the corresponding subway station.

For example, when a user arrives at a subway station, if the ticket counter installed in the subway station is stored as pattern information (for example, when a user arrives at a bus stop, a sign in the image received through the camera of the auxiliary device is found. When a predetermined number (or ratio) is accumulated for a predetermined period or more, the controller of the main device may control to output subway arrival time information at the corresponding subway station when the ticket counter is recognized from the captured image received from the auxiliary device.

In this case, the subway arrival time information may be output from only one of the main device and the auxiliary device, or may be output from both the main device and the auxiliary device.
