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 of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

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. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as " proximity touch & The act of actually touching an object on the screen is called a " contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed 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. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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.

Thus, 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 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. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a 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 sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected 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 change of light, and position information of the object to be sensed can be obtained through the calculation.

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

The frame portion is supported on the head portion, and a space for mounting various components is provided. As shown in the figure, electronic parts such as a control module 280, an audio output module 252 and the like may be mounted on the frame part. In addition, a lens 203 covering at least one of the left and right eyes may be detachably mounted on the frame portion.

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

The display unit 251 may be implemented as a head mounted display (HMD). The HMD type refers to a display method that is mounted on a head and displays 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 arranged to correspond to at least one of the left eye and the right eye so that the user can directly provide an image in front of the user's eyes. In this figure, the display unit 251 is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display unit 251 can project an image with the user's eyes using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

As described above, the image output through the display unit 251 can be overlapped with the general view. The mobile terminal 200 can provide an Augmented Reality (AR) in which a virtual image is superimposed on a real image or a background and displayed as a single image by 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 configured to photograph a forward image. Since the camera 221 is located adjacent to the eye, the camera 221 can acquire a scene viewed by the user as an image.

Although the camera 221 is provided in the control module 280 in this figure, it is not limited thereto. The camera 221 may be installed in the frame part, or may be provided in a plurality of ways to acquire a stereoscopic image.

The glass-type mobile terminal 200 may include user input units 223a and 223b operated to receive control commands. The user input units 223a and 223b can be employed in any tactile manner, such as a touch or a push, in a tactile manner. This figure illustrates that the frame unit and the control module 280 are provided with user input units 223a and 223b of a push and touch input method, 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 an acoustic output module 252 for outputting sound. The sound output module 252 may be configured to transmit sound in a general sound output mode or a bone conduction mode. 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 brought into close contact with the head and vibrates the skull to transmit sound.

The mobile terminal according to the present invention analyzes images inputted through a camera to provide appropriate information according to a situation where the user is located. For example, when analyzing an image inputted through a camera, if the bus stop is recognized, the mobile terminal can output bus arrival time information at the bus stop. As another example, when analyzing an image inputted through a camera, if the movie ticket machine is recognized, the mobile terminal can output the movie time table information in the theater.

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

However, if the camera is always kept on to provide information appropriate to the situation in which the user is located, the battery of the mobile terminal will soon be discharged. Accordingly, there is a need to provide a method for reducing power consumption of the mobile terminal when providing information suitable for a situation where the user is placed through the camera.

To this end, the mobile terminal according to the present invention controls to keep the camera in an off state or turn on the camera for a long period of time (referred to as a first time period) briefly, , It is possible to switch the camera to the on state for a predetermined time or control the camera to be turned on for a short time period (referred to as the second time period) briefly.

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.

The mobile terminal according to the present invention can function as an auxiliary device for assisting another device or can operate as a main device for 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 receiving a call signal or a text message from another device, And the like.

When the mobile terminal is used as a periodizer, the control unit can receive an image captured by the auxiliary device from the auxiliary device while directly executing the application installed in the memory. On the other hand, when the mobile terminal is used as an auxiliary device, the mobile terminal may transmit the image photographed through 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. Ancillary and primary devices can communicate via a communication scheme such as Bluetooth, NFC, Wi-Fi, or Wi-Fi Direct.

For convenience of explanation, in the embodiments described later, it is assumed that the main device is a bar-type smartphone and the auxiliary device is a glass-type terminal. However, the embodiments described below may be applied to various other types of mobile terminals. For example, while a glass-type device is used as a main device, a bar-type device may be used as an auxiliary device, and a wearable device such as a necklace type, a watch type, a ring type, The device may be capable of operating as a main or auxiliary device.

However, when a glass type or a necklace type device is used as an auxiliary device, it is highly likely that the user's gaze and the camera shooting direction coincide with each other, so that the image input through the camera is expected to match the space area Side effects that can occur.

In the following embodiments, functions of the main apparatus and the auxiliary apparatus will be described separately. Specifically, the main device plays the role of driving the application, and the auxiliary device plays the role of providing the main device with the image photographed through the camera.

However, the roles of the main device and the auxiliary device, which will be described later, may be integrated in one device. For example, the mobile terminal according to the present invention may analyze an image photographed through a camera while an application is being executed, and output information suitable for a situation where the user is located. That is, it will be apparent to those skilled in the art that, in the embodiments described below, if the communication process between the main apparatus and the auxiliary apparatus is omitted and the following embodiments can be performed through one mobile terminal . In addition, a mobile terminal that integrates the roles of the main device and the auxiliary device, as well as the main device and the auxiliary device described below, may also be regarded as belonging to the scope of the claims of the present invention.

The present invention will be described in detail on the basis of the above description.

Figure 3 is a flow diagram of a method for providing information appropriate to the context of a user in accordance with the present invention.

When the application is executed in the main device (S301), the main device can 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 or not the application supports camera analysis, and the like. The main apparatus may transmit, together with the execution information, a signal requesting the auxiliary apparatus to wake up the camera every first time period.

When the application executed in the main device is an application providing information suitable for a situation where the user is laid through camera analysis or when receiving a signal requesting to wake up the camera intermittently from the main device, Can be controlled to wake up every time the first time period and take a picture of the surroundings (S303). Specifically, the control unit of the auxiliary device controls the camera to wake up every time period for a predetermined period of time, and then transmits the captured image to another device. At this time, the image taken by the camera waking up every first time period may be a moving image or at least one still cut.

Even when the application executed in the main device is an application providing information suitable for the situation in which the user is laid through the camera analysis, the auxiliary device can keep the camera in the Off state until the predetermined condition is satisfied.

The control unit of the auxiliary device can transmit the image photographed through the camera to the main device. The control unit of the main unit can provide information suitable for the situation in which the user is positioned through the image analysis received from the auxiliary equipment.

When the control unit of the main unit recognizes that the predetermined condition is satisfied in the state that the application is being executed through the main unit (S304), the control unit of the main unit transmits the signal requesting the auxiliary equipment to change the wake- (S305). Then, the control unit of the auxiliary device can control the camera to wake up every second time period shorter than the first time period and take a picture around the second time period (S306).

If the camera of the auxiliary device is kept in the OFF state, the control unit of the auxiliary device controls the camera to wake up every predetermined period of time and take a picture of the surrounding area in response to the request signal received from the main device, May be controlled to maintain the On state.

Here, the wake-up period of the camera may be the time from when the camera is turned on to the next time when the camera is turned on, the time until the camera is turned on, It is possible. In addition, the time during which the camera is maintained in the ON state may be fixed or variable depending on the wakeup period. For example, when the camera is set to wake up every first time period, the controller controls the camera to maintain the On state for one second. When the camera is set to wake up every second time period, To maintain the On state for a second.

As the camera's wake-up period becomes shorter, the ancillary device will be able to transmit the captured image to the main device more often.

In Fig. 3, the control unit of the main apparatus is shown as judging whether or not a predetermined condition is satisfied. Unlike the example shown in Fig. 3, the control unit of the auxiliary device may determine whether or not a predetermined condition is satisfied. In this case, the process by which the main device transmits the request signal to the auxiliary device may be omitted.

Whether or not the predetermined condition is satisfied may be determined based on the pattern information accumulated for a predetermined period, the moving speed of the user (that is, the mobile terminal or other apparatus), the path where the user A signal generated by the sensing unit, the number of steps of the user, the presence or absence of a predetermined object in the image photographed by the camera, and the like.

Although not shown, when the control unit of the main device recognizes that the predetermined condition is satisfied in the state where 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 Signal can be transmitted. The control unit of the auxiliary device can then control the camera to wake up again every first time period.

As another example, the control unit of the auxiliary device may control to switch the camera back to the OFF state in response to the request signal received from the main device.

When the application is terminated in the main device (S307), the main device can transmit termination information indicating that the application is terminated to the auxiliary device (S308). Then, the control unit of the auxiliary device can switch the camera to the Off state (S309). That is, the auxiliary device can control the camera to remain ON only while the application is being executed in the main device.

As described above, the auxiliary device can transmit the image photographed through the camera to the main device while the application is being executed through the main device. Then, the main apparatus recognizes the situation where the user is placed through the image analysis taken through the camera, and provides the user with appropriate information.

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

<Case 1 - Providing traffic information>

The mobile terminal according to the present invention can be used for providing traffic information to a user. An example of providing traffic information through the flowchart of FIG. 4 will be described in detail.

4 is a diagram showing an example in which traffic information is outputted. For convenience of explanation, it is assumed that an application for providing traffic information (for example, an application for notifying an arrival time of a bus by a stop or an application for notifying a subway arrival time) is being executed do. Even when the traffic information providing application is executed in the background state, the following embodiments can be applied.

If the application is running through the main device, the control unit of the auxiliary device can control the camera to wake up every first time period (S401). In addition, the control unit of the auxiliary device can transmit the image photographed through 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 photographed image is received from the auxiliary device, the control unit analyzes the photographed image to determine whether the photographed image includes the first object or the second object. Here, the first object is for adjusting the wakeup period of the auxiliary device camera, and the second object may be for outputting information suitable for the situation in which the user is located.

When a first object is found through a camera or when pattern information accumulated in a predetermined period, a moving speed of a user (i.e., a mobile terminal or another apparatus), a path where a user (i.e., a mobile terminal or another apparatus) When it is determined that the predetermined condition is satisfied in consideration of the usage information, the current position, the signal generated in the sensing unit, the number of steps of the user, etc., the control unit of the main device changes the wake- (S404).

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

If the second object is found from the photographed image received from the auxiliary device, or if the predetermined condition is satisfied together with the second object (S407), the control unit of the main device can output the necessary information to the user (S408). At this time, the control unit of the main device may transmit information necessary for the user to the auxiliary device so as to control the information to be outputted through the auxiliary device, and some of the information required for the user is outputted through the auxiliary device, Or the like.

5 is a diagram showing an example in which the wakeup period of the auxiliary-device camera according to the situation is changed.

In the example shown in Fig. 5, the wake-up period of the camera is shown to be shorter in a case where the user arrives at a bus stop or is different around the subway station based on the life pattern of the user.

5 is divided into a plurality of sections, and the operation of the main apparatus and the auxiliary apparatus according to the sections will be described in detail. In Fig. 5, the numbers written in the original designation indicate numbers identifying each section.

Section 1

When the user leaves the house and moves to the bus stop while the traffic information application is running through the main device, the camera of the auxiliary device can wake up and photograph the first wakeup period.

The control unit of the main device moves the user to the bus stop based on the walking speed of the user, the path that the user of the current time period normally travels, the current position, the analysis of the shot image received from the auxiliary device, It is possible to recognize that a state exists.

For example, if the behavior of moving from the home to the bus stop is repeated in the morning time period for a predetermined period, the control unit of the main device may store the movement of the morning time user to the bus stop as pattern information. The pattern information may include information such as the route the user takes to move to the bus stop, the average walking speed information of the user, and the landmark placed on the route to the bus stop.

When the user is moving to the bus stop but it is determined that the user is still away from the bus stop by a predetermined distance or longer than a predetermined time until he arrives at the bus stop on the basis of the pattern information, The camera of the apparatus can be controlled to wake up every first wakeup period.

Based on the position of the main device or the user's walking speed, the control unit of the main device can calculate whether the user is away from the bus stop by a predetermined distance or whether or not a predetermined time or more remains before arriving at the bus stop.

The second section

If the landmark on the route to the bus stop is found on the shot image received from the auxiliary device, or if the position of the main device is within the first reference distance from the bus stop, or if the remaining time If the first reference time is equal to or shorter than the first reference time, the control unit of the main device may request the auxiliary device to change the wake-up period of the camera.

For example, when a user moves to a bus stop, if the crosswalk is installed on the route as a pattern information, the control unit of the main unit may switch from the captured image received from the auxiliary device to the auxiliary device It may send a signal requesting to change the wake-up period of the camera.

At this time, in order to prevent the wake-up period of the camera from being shortened when a crosswalk other than the crosswalk around the bus stop is recognized, the control unit of the mainwheel is positioned within a first reference distance from the bus stop , Or when the time remaining until reaching the bus stop is less than or equal to the first reference time, when the pedestrian crosswalk is found, the auxiliary device may be requested to change the camera wakeup period.

When the request signal is received from the main unit, the auxiliary equipment can change the wake-up period of the camera. Specifically, the control unit of the auxiliary device can change the wake-up period of the camera from the first time period t1 to the second time period t2.

At this time, the control unit of the auxiliary device may control the camera so that the wakeup period of the camera is changed immediately in the second time period in the first time period. However, as in the example shown in Fig. 5, It may be controlled so as to be gradually shortened from the period and to be the second time period at the end. In this case, the controller of the ancillary apparatus controls the wake-up period of the camera gradually toward the second time period as the position of the ancillary apparatus (or main apparatus) approaches the bus stop or the remaining time until arrival at the bus stop becomes shorter .

Section 3

If a landmark recognizable as a bus stop is found on the photographed image received from the auxiliary device or if the position of the main device is located within a second reference distance shorter than the first reference distance from the bus stop, If the remaining time is shorter than the second reference distance shorter than the first reference time, the control unit of the main device can output bus arrival time information at the bus stop.

For example, when a user arrives at a bus stop and the sign installed at the bus stop is stored as pattern information (for example, when the user arrives at the bus stop, the sign in the image received through the camera of the auxiliary device is found The control unit of the main device controls the bus arrival time information at the bus stop to be outputted when the sign is recognized from the photographed image received from the auxiliary device .

At this time, the bus arrival time information may be output from either the main apparatus or the auxiliary apparatus, or may be output from both the main apparatus and the auxiliary apparatus.

6 is a diagram showing an example in which bus arrival time information is outputted.

6A, the control unit of the main device 10 receives information on the arrival time of the bus that the user is supposed to board on the bus arrival time information through the auxiliary device 20 And the like.

At this time, the control unit of the main device 10 analyzes the image input through the camera immediately before the user is recognized as the bus in the morning time period for a predetermined period, so that the user expects the bus number expected to be boarded can do. As another example, the control unit of the main device 10 stores the destination when the user gets on the bus as pattern information in the morning time period for a predetermined period of time, and then sends the bus to the destination to the bus .

The control unit of the main device 10 may output some of the bus arrival time information through the auxiliary device 20 and output the rest through the main device 10. [ For example, in FIG. 6A, any one of the arrival time information 610, which is expected to be the fastest among the buses expected to be loaded by the user, is displayed through the display unit of the auxiliary device 20 And the arrival time information of the buses expected to be loaded by the user and the estimated arrival time information 620 to the destination are output through the main device 10.

When the 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 is configured to transmit the bus arrival time information to the main device 10 Can also be controlled so that an indicator 615 indicating that the bus arrival time information is output is output.

The bus arrival time information output through at least one of the main apparatus 10 and the auxiliary apparatus 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, 10), or if the user is using another application (for example, in the middle of a conversation or playing a game) via the main device 10, the main device 10 may use the auxiliary device 20 ) To be notified that the bus will arrive soon.

Specifically, via the auxiliary device 20, a message 620 indicating that the vehicle will arrive soon, as in the example shown in Fig. 6B, may be output. The control unit of the auxiliary device 20 may output a message together with a vibration or a sound.

The control unit of the main device 10 can control the auxiliary device 20 to output a notification to guide the bus ride when the user recognizes the bus to be boarded on the video image received through the auxiliary device 20 .

Specifically, a message 630 indicating that the bus has arrived may be outputted through the auxiliary device 20, as in the example shown in FIG. 6C. The control unit of the auxiliary device 20 can output vibration, sound, or the like together with the message.

6 (b) and 6 (c), the notification is outputted from the auxiliary device 20, but the main device 10 may output the notification.

Section 4

If it is determined that the user has boarded the bus, the main device may request the auxiliary device to change the camera's wake-up period. Specifically, when the image input through the camera is photographed inside the bus, the bus fee is paid through the card registered in the main device, or when the gyro sensor or the acceleration sensor or the like is mounted on the bus, The main apparatus can request the auxiliary apparatus to change the wake-up period of the camera.

When the request signal is received from the main unit, the auxiliary equipment can change the wake-up period of the camera. Specifically, the control unit of the auxiliary device can control the wakeup period of the camera to change from the second time period to the first time period again.

At this time, the control unit of the auxiliary device may control the camera so that the wakeup period of the camera changes immediately in the first time period in the second time period, but as in the example shown in Fig. 5, It may be controlled so as to become gradually longer than the period and reach the end time in the first time period.

Section 5

While the user is riding the bus, images taken inside the bus will be input through the camera. It is preferable to set the wakeup period of the camera to be long while the user is riding the bus because it is difficult to find a special object for grasping the user situation through the image photographed inside the bus.

Accordingly, the control unit of the auxiliary device can control so that the wakeup period of the camera maintains the first time period while the user is riding the bus.

Section 6

When it is determined that the user has got off the bus and the user's pattern information is taken into consideration, if the user is expected to transfer to the second transportation means (e.g., subway) after getting off the bus, To request a change in the wake-up period of the wake-up period.

For example, when the main device detects an image on the outside of the bus through an image captured from an auxiliary device, when the bus getting information is received through a card registered in the main device, or when a gyro sensor or an acceleration sensor, The control unit of the main apparatus can judge that the user has got off the bus. In addition, if the behavior of getting off the bus at the same place is repeated during the predetermined period of time in the morning, the control unit of the main unit may stop the operation of the bus when the user enters the bus within a predetermined distance from the usual bus- It may be judged that it has gotten off.

If the behavior of moving to the subway station after repeating the bus for a predetermined period is repeated, the control unit of the main unit can store the moving to the subway station after getting off the bus stop at a predetermined position as pattern information.

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

When the request signal is received from the main unit, the auxiliary equipment can change the wake-up period of the camera. Specifically, the control unit of the auxiliary device can change the wake-up period of the camera from the first time period to the second time period.

At this time, the control unit of the auxiliary device may control the camera so that the wakeup period of the camera is changed immediately in the second time period in the first time period. However, as in the example shown in Fig. 5, It may be controlled so as to be gradually shortened from the period and to be the second time period at the end. In this case, the control unit of the auxiliary device controls the camera so that the wake-up period of the camera is gradually adjusted toward the second time period as the position of the auxiliary device (or the main device) approaches the subway station or the remaining time till the subway station arrives can do.

Section 7

When a landmark that recognizes a ticket gate or a platform is found on the shot image received from the auxiliary device or the position of the main device is located within a second standard distance shorter than the first reference distance from the subway station, If the remaining time is less than the second reference distance shorter than the first reference time, the control unit of the main device can output the subway arrival time information at the corresponding subway station.

For example, when an ordinary user arrives at a subway station, and an information device installed in a subway station is stored as pattern information (for example, when a user arrives at a bus stop, The control unit of the main apparatus can control to output the subway arrival time information at the corresponding subway station when the ticket table is recognized from the photographed image received from the auxiliary apparatus.

At this time, the subway arrival time information may be output from either the main apparatus or the auxiliary apparatus, or may be output from both the main apparatus and the auxiliary apparatus.

7 is a diagram illustrating an example in which subway arrival time information is output.

7, the control unit of the main device 10 controls the subway information 710 to be received in the earliest time from the present time to be outputted through the auxiliary device 20, (720) can be controlled to be output through the main device (10). In FIG. 7, it is shown through the main device 10 that boarding position recommendation information is also outputted together with the subway platform of the user.

In the case where subway 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 can also receive the subway arrival from the main device 10 as in the example shown in FIG. An indicator 715 indicating that the time information is being output may be output.

Section 8

If it is determined that the user has boarded the subway, the main device may request the auxiliary device to change the wake-up period of the camera. Specifically, when an image input through a camera is photographed inside the subway, or when a gyro sensor or an acceleration sensor detects a shake or acceleration such as when the subway is loaded, May request to change the wakeup period.

When the request signal is received from the main unit, the auxiliary equipment can change the wake-up period of the camera. Specifically, the control unit of the auxiliary device can control the wakeup period of the camera to change from the second time period to the first time period again.

At this time, the control unit of the auxiliary device may control the camera so that the wakeup period of the camera changes immediately in the first time period in the second time period, but as in the example shown in Fig. 5, It may be controlled so as to become gradually longer than the period and reach the end time in the first time period.

Section 9

While the user is riding the subway, images taken inside the subway will be input through the camera. Since it is difficult to find a special object for grasping the user situation through the image photographed inside the subway, it is preferable to set the wakeup period of the camera to be long while the user is riding the subway.
