Mobile phone with moving-safety function "

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly, to a mobile phone having a suspend function in a situation where a dangerous thing may occur during use.

Mobile phone performance such as smart phones, screen size, usage and ability to use are continuously increasing. In addition, the user's visual utilization such as watching a video using a mobile phone, a game, and navigation is increasing.

Since the smartphone mainly uses the touch panel, input is not possible without looking at the screen of the mobile phone. Therefore, the user of the mobile phone tends to keep watching the screen regardless of the surrounding situation. For example, if you are walking or traveling on a bicycle, you may not be aware of the surroundings and may encounter other pedestrians or poles, or you may fall off the stairs by not paying attention to your feet, There are many accidents such as falling into water at the fountain. In this way, when walking while viewing a mobile phone, the user's basic moving speed is slow, which can be a cause for other pedestrians.

As already mentioned, operating a mobile phone while walking is risky, but no specific measures have yet been taken.

FIG. 1 is a block diagram of a mobile phone according to an embodiment of the present invention, and FIG. 2 is a flowchart for determining contents to be displayed on a display unit in a mobile phone according to an embodiment of the present invention.

The mobile phone is a smart phone and includes a display unit 10, a user interface 20, a control unit 30, a communication unit 40, a moving image function unit 50, a game function unit 60, a memory unit 70, (90), a status information acquisition unit (95), and a display content determination unit (100).

The display unit 10 is a display screen mainly composed of a liquid crystal display, and is used for viewing a moving image, for displaying a navigation function, or for displaying a game screen. The user interface 20 is composed of an input device such as a touch panel sensor and receives various operations from the user. The control unit 30 is a functional unit for controlling the entire operation of the cellular phone, and operates a predetermined program according to user's operation to control each part. Also, an image to be displayed on the display unit is generated.

The control unit 30 also functions as an operation program determining unit of the present invention as described below. The communication unit demodulates the received call signal, converts it into an analog signal, transfers it to a handset (not shown), or transmits and receives mail and web site through the Internet.

In addition, the moving image function unit 50 is a function implementing unit for realizing image playback in the mobile phone. The game function unit 60 is a functional unit for realizing a game function in a mobile phone. These functional units are realized by executing a program stored in a separate memory.

The memory 70 has an internal storage device and an external storage device. The internal storage device includes a ROM for storing a basic program or a RAM for operating various programs. The external storage device is composed of an SD card or an HDD, and includes a phone book for mobile phones, map information, and various application programs.

The geographical information acquisition unit 90 is a function for acquiring geographical information of the cellular phone by various sensors such as GPS. The state information acquisition unit 95 also has various sensors such as an acceleration sensor, and can acquire information other than the position with respect to the cellular phone. The geographical information acquisition unit 90 and the state information acquisition unit 95 constitute the user mode estimation unit of the present invention together with the control unit 30, and the details thereof will be described later.

The display content determining unit 100 determines display contents of a user mode such as a user mode, for example, a stop mode, a walking mode, a running mode, a vehicle movement mode, and the like, Function. In addition, the display content determining unit 100 determines whether or not to perform an operation restriction on a user interface that is an operating unit. Details will be described later.

FIG. 2 is a flowchart for determining contents of display of a mobile phone according to an embodiment of the present invention, and will be described with reference to this flowchart. FIG.

First, the display content judging unit 100 requests information on the control unit of the terminal, that is, information on the type of the application program being executed and the user mode information (S1).

Next, the control unit 30 receiving the request requests the geographical information acquisition unit 90 to specify the location of the mobile phone (S2). Here, the geographical information acquisition unit 90 includes various sensors such as a GPS, an air pressure sensor, a Wifi radio wave information acquisition unit, an RFID reader, and the like. Then, the geographical information acquisition unit 90 acquires information for specifying the position of the mobile phone from the sensor or the like and transmits it to the control unit 30 (S3).

For example, information such as latitude, longitude, and altitude can be obtained from the GPS sensor, and information on whether or not it is at a high altitude from the air pressure sensor can be obtained. Furthermore, a list of the Wifi access point identification information and the radio wave intensity is created from the detection data of the Wifi signal information acquisition unit, and the list is transmitted to a geographic information server (not shown) to receive the position of the mobile phone calculated by the geographical information server . On the other hand, in railroad, train, etc., each vehicle can usually be connected to Wifi, so that information on where the user is can be obtained from the information. In addition, the RFID tag reader can detect the current position of the mobile phone by detecting the RFID tag installed in the underground shopping mall and the inside of the room.

The sensor of the geographical information acquisition unit 90 mounted on the mobile phone may be any sensor as long as information on the position of the mobile phone can be obtained. In addition, the mobile phone does not need to include all such sensors.

Next, the control unit 30 requests information for identifying the state of the mobile phone to the state information acquisition unit (S4). Here, the state information acquisition unit 95 includes various sensors such as a proximity sensor, a temperature / humidity sensor, a pressure sensor, and an acceleration sensor, for example. Then, the state information acquisition unit 95 acquires information from the sensor or the like to grasp the state other than the position of the cellular phone, and transmits the information to the control unit 30 (S5).

For example, the proximity sensor can sense whether the user is approaching the face to the mobile phone. In addition, the temperature / humidity sensor can determine the usage environment of the mobile phone. In addition, the pressure sensor allows the user to know whether the mobile phone is held by the user. In addition, the gyro sensor can detect the direction of the mobile phone. In addition, the acceleration sensor can detect the acceleration of each of the three axes, so that the moving speed of the mobile phone can be grasped by integrating the acceleration component in the horizontal direction. Also, if the acceleration component in the vertical direction is integrated twice, the displacement in the vertical direction of the mobile phone can be detected by the vibration.

In addition, as long as information on the state of the mobile phone, such as the sensor of the state information sensing unit mounted on the mobile phone, can be acquired, it is not necessary that the mobile phone is equipped with all of these sensors. However, in order to improve the accuracy of the mobile phone status information, it is desirable to mount at least an acceleration sensor. The steps 2 to 5 may be changed, and the processes are performed simultaneously and concurrently.

Next, the control unit 30 determines which mode of the predetermined user mode predetermined by the user (owner) using the mobile phone is in accordance with the information acquired from the geographical information acquisition unit 90 and the state information acquisition unit 95 (S6). Here, the predetermined user mode is, for example, four types: a stop mode, a walking mode, a running mode, and a vehicle movement mode.

Whether or not the user is moving can be estimated from the information from the acceleration sensor. Here too, the output of other sensors, etc. can be used to support the accuracy of the estimation.

A method of estimating the user mode will be described with a few examples. For example, the GPS of the geographical information acquisition unit 90 can determine whether the mobile phone is in the position on the line, for example, from the longitude / latitude information and the map data. Further, it can be grasped from the acceleration sensor of the state information acquiring unit 95 that the vehicle is moving at a speed of 50 km / h, for example. In this case, since the user is likely to be in the moving train, the user mode can be assumed to be in the vehicle moving mode. In this case, since the temperature and humidity can be obtained to some extent in the underground or the like in the air pressure sensor or in the vehicle, it can be regarded as reliable if the user knows from the temperature / humidity sensor whether the user is indoors.

If the mobile phone is found to be close to the access point of the train from the sensed data in the Wifi signal information acquisition unit, this estimation becomes more certain. In addition, although matching between the access point and the vehicle is required, such information can be acquired by storing the information in a memory or searching the Internet.

The GPS of the geographical information acquiring unit 90 can determine whether the geographical information is in the street from the longitude / latitude information and the map data. It can be assumed that the user mode is a running mode if it can be recognized that the acceleration sensor information is moving to about 10 km per hour. In this case, the temperature / humidity sensor can detect that the user is outdoors, and the estimation becomes more certain when the period of vibration obtained from the acceleration sensor is in the range of the running pitch at the time of running. It is recommended that you remember the driving pitch during running and the pitch contents when walking on the mobile phone in advance.

If the geographical information acquisition unit 90 can grasp whether the longitude / latitude information and the map data are on the road in the GPS, and if it can be grasped that the acceleration sensor is moving at a speed of 3 to 5 kilometers per hour from the information, Can be estimated to be the walking mode. In this case, if the period of the vibration obtainable by the acceleration sensor is in the range of the pitch when walking, this estimation becomes more certain.

When hardness / latitude information can not be obtained from the GPS of the geographical information acquisition unit 90, it can be estimated that the occupant is walking within the range of the walking speed on the output of the acceleration sensor. However, An output from the RFID tag reader can be obtained from an underground shopping mall or the like and this estimation becomes more certain when the position of the user can be confirmed from the data sensed by the Wifi signal information acquisition unit.

Next, if the acceleration sensor is a place where it is possible to grasp that the moving speed is zero in the information, it can be estimated that the user mode is the stop mode. In this case, when the user is in a place other than the train and the road in the longitude / latitude information and the map data in the GPS of the geographical information acquisition unit 90 and the magnitude of the vibration calculated by outputting the output of the pressure sensor from the constant acceleration sensor is If it is smaller than the predetermined value, it is more reliable that the user does not move but sees the mobile phone in the stationary state.

Next, returning to Fig. 2, the control unit 30 acquires the type of the application program being executed (S7). In the case of this embodiment, the types of application programs include three types of video viewing, navigation, and games. However, the present invention is not limited to this, and other programs may be used as long as the programs operate on the mobile phone and use the display unit. In other words, the present invention is not limited to the case where the program is limited to a program in which the user must necessarily view the display unit 10, and is not a program that does not need to view the display unit 10, for example, to listen to music.

Then, the control unit 30 notifies the display content deciding unit 100 of the user mode information estimated in step S6 and the type information of the program obtained in step S7 (S8). The display content determining unit 100 determines contents to be displayed on the display unit 10 in accordance with the information notified from the control unit 30 To the display unit 10 (S10). When the operation from the user interface 20 is limited according to the result of the display content determining unit 100, the user's input is selectively received according to the job restriction.

For example, when changing a train, the user mode is to move from (a) train line 1 (b) to walk (c) from train line 3. In this case, if the user is watching a moving picture on a mobile phone, the user mode is estimated to be moving while the moving picture is being watched in (a). Next, the user is assumed to be walking in the user mode at the time of transfer (b), and the running application program is judged as watching a moving picture. Therefore, the moving picture viewing is stopped here. Concretely, the thumbnail of the moving picture being watched on the initial screen is notified that the still image is displayed and the pause state. Also, in (c), the user mode is estimated to be moving, and the running application is determined to be watching the video, so that the video is automatically returned to the normal video playback screen.

As described above, in the present invention, the minimum information is provided according to the individual user mode and the type of the running application program, rather than simply stopping all the application program functions during the movement of the pedestrian. Therefore, if the mobile phone runs on the back of the mobile phone while the video is running, the image may be displayed through the camera so that the front of the mobile phone is visible. In this case, a program other than the video playback application is started.

Also, while the program described only three types of video viewing, navigation, and games, it is of course possible to set it for other applications.

For example, during stopping or during a high-speed movement for mail reception, it is possible to operate the switching screen and display the mail body text until reaching the mail reception. However, when the user is walking, only the name of the sender is displayed, In this case, a screen that notifies that the user has just received the e-mail may be used.
