For example, when a user moves the mobile terminal toward a specific location in the sky, a constellation at that location is displayed on the screen.

According to the prior art, only a very basic theory about the mobile terminal that can provide the above-described astronomical information is presented, and a practical, specific, and commodity that enables the user to receive astronomical information in a fun and convenient manner. There is a problem that there is no mobile terminal that can be implemented.

In addition, according to the related art, even if the above-described celestial information is provided, the user does not provide a function of guiding the position of the celestial body to be searched for.

The present invention solves the above problems and at the same time proposed according to the latest trends and requests, the present invention, as well as providing the celestial celestial information located in the direction corresponding to the orientation and altitude to which the terminal is directed, An object of the present invention is to provide a celestial direction guidance method capable of guiding a position of a celestial body that a user wants to find and a mobile terminal having a celestial direction guidance function.

1 is a diagram illustrating an example of astronomical observation using a mobile terminal according to the present invention. 1 shows the constellations of the northern sky seen from Seoul, South Korea in December.

In the present invention, the celestial body is a concept including all universe objects in the sky that can be identified by the human eye or astronomical telescope such as stars, constellations, comets, galaxies.

First, it is assumed that a user of a mobile terminal wants to observe Gemini among the constellations shown in FIG. 1 on the screen of the terminal. However, most general users without a deep knowledge of the constellation do not know where Gemini is in the sky.

The mobile terminal according to the present invention can output celestial information located in a direction that the celestial terminal is directed to as video information or audio information. The specific implementation process and operation will be described later.

For example, assuming that the mobile terminal is in state A (100a) shown in FIG. 1, the Andromeda constellation and the Cassiopeia constellation are output on the screen 200a of the terminal. However, in order to observe the Gemini desired by the user on the screen of the mobile terminal, the orientation direction of the mobile terminal must be changed from the state A (100a) to the state B (100b). That is, when the mobile terminal is in the state B (100b), Gemini is displayed on the screen 200b of the terminal.

2 is a flowchart of a celestial direction guidance method according to a preferred embodiment of the present invention.

Referring to Figure 2, it will be described in detail a preferred embodiment of the celestial direction guidance method according to the invention as follows.

First, the object name is input [S200]. The input celestial name includes all celestial bodies, such as stars, constellations, comets, and galaxies.

In addition, astronomical position information indicating a celestial position of a celestial body corresponding to the received celestial body name is obtained [S210].

In general, as a coordinate system indicating the position of the heavenly body, a horizontal coordinate system (horizon coordinates system), the equatorial coordinates (equatorial coordinates system), ecliptic coordinates (ecliptic coordinates system), galactic coordinates (galactic coordinates system) are representative.

The horizontal coordinate system is a coordinate system in which the reference plane is the horizontal plane and the reference point is the north point, and the measuring method measures the azimuth along the horizontal plane from the north point clockwise (east) to the foot of the celestial body, and measures the azimuth angle from the foot of the celestial body to the celestial body + , Height towards the bottom.

The equatorial coordinate system is a coordinate system in which the reference plane is the equator plane and the reference point is the vernal equinox.The measuring method measures the right ascension in time units along the equator plane from the vernal equinox to the feet of the celestial body in the direction of the earth's revolution, Decline the Antarctic side with-.

The ecliptic coordinate system is a coordinate system in which the reference plane is the ecliptic plane and the reference point is the vernal equinox, and the measuring method measures angles along the ecliptic plane from the vernal equinox to the feet of the celestial body in the direction of the earth's revolution, and measures northward from the celestial feet to the north +, south By-measure the value by the latitude.

The galactic coordinate system is a coordinate system that is the galaxy (galactic equatorial) and the reference point is the galactic center (Sagittarius), and the measuring method measures the angle of the silver mirror from the center of the galaxy to the east along the galaxy and measures the galaxy from the feet of the celestial body to the celestial body. The North Pole of + and South-Negative value.

On the other hand, each coordinate system can be converted to another coordinate system. For example, the horizon coordinate system may be converted to the equator coordinate system, and the equatorial coordinate system may be converted to the horizon coordinate system.

Since the coordinate calculation method of the celestial position by each coordinate system and the conversion to other coordinate systems are well known, detailed description thereof will be omitted.

The celestial position information acquired in the celestial position information acquisition process [S210] may be formed of various coordinate systems as described above. Hereinafter, assuming that the acquired celestial position information is made of an equator coordinate system will be described.

Meanwhile, the process of acquiring the celestial position information [S210] may be performed by referring to a database in which astronomical coordinates having a celestial name and a specific coordinate system are matched. The database may be inside or outside of the mobile terminal according to the present invention. When the database is outside of the mobile terminal according to the present invention, a request for obtaining the celestial position information corresponding to the celestial name should be made to the database.

Then, terminal orientation position information indicating a celestial position indicated by a direction including a direction and an altitude pointed to by the terminal (hereinafter referred to as a terminal orientation direction) is obtained [S220].

The terminal-oriented position information refers to celestial position in the direction in which the terminal is directed, rather than information about where the terminal is located. The terminal-oriented position information, like the celestial position information, may be made of various coordinate systems. In the following, it is assumed that the obtained terminal-oriented position information is made of a horizontal coordinate system. The reason why the terminal-oriented position information is configured and described in the present specification is a horizontal coordinate system because the horizontal coordinate system is the simplest when calculating the position of a celestial object viewed by a user. Therefore, the coordinate system of the terminal-oriented position information is not necessarily limited to the horizon coordinate system.

3 is an embodiment of a specific process for obtaining terminal-oriented location information.

Referring to FIG. 3, the terminal-oriented location information acquisition process [S220] will be described in detail as follows.

First, the terminal location information, the terminal orientation information and the time information of the terminal is acquired [S300], the terminal orientation information consisting of a horizontal coordinate system corresponding to the obtained terminal location information, terminal orientation information and time information. Obtain [S310].

The terminal position information refers to the earth position of the terminal. Representative position information includes latitude / longitude information. In addition, the terminal location information may be a specific area name such as Seoul, Korea, Washington, USA.

Meanwhile, the terminal location information may be directly input by a user or obtained by using a GPS signal received from a GPS satellite. When the mobile terminal has a mobile communication module for data transmission and reception with a mobile communication network, the mobile station may receive system parameters from a mobile communication base station to obtain location information of the terminal. In general, latitude / longitude information is included in a system parameter transmitted from a mobile communication base station.

The terminal orientation information may be obtained using a direction recognition module (for example, a geomagnetic sensor) that recognizes a direction in which the terminal is directed. However, it is preferable to acquire direction information of the terminal by using not only the direction recognition module but also an operation recognition module (for example, an acceleration sensor or a gyro sensor) that recognizes the operation of the terminal. This is because using the direction recognition module and the motion recognition module at the same time improves the acquisition speed of the direction information and the accuracy of the data. Details regarding the direction recognition module and the motion recognition module will be described later.

Here, the azimuth and the altitude included in the terminal-oriented direction information are concepts that encompass all of the terms used in each coordinate system for indicating the position of the celestial body. For example, in the equator coordinate system, the orientation is right ascension and the altitude is declination. In the horizontal coordinate system, the azimuth represents an azimuth angle and the altitude represents an altitude.

The time information may be obtained through the same path as the terminal location information. That is, the time information may be obtained directly from a user, by using a GPS signal, or in the case of a mobile terminal capable of mobile communication, using a system parameter received from a mobile communication base station.

When the terminal location information, the terminal orientation information, and the time information are obtained, a horizontal coordinate corresponding thereto may be calculated. The calculated horizontal coordinates become the orientation position information of the terminal. Of course, as described above, the orientation position information of the terminal does not necessarily have to be horizontal coordinates.

In addition, astronomical information corresponding to the obtained terminal orientation information is output (S230). The output method of the astronomical information may vary. For example, text related to the celestial body image, celestial name or legend may be displayed as image information, or may be output as audio information. In addition, it is also possible to output in the form of a video, animation, flash.

Then, the obtained celestial position information is compared with the obtained terminal orientation position information [S240], and it is determined whether the comparison result is within a predetermined error range [S250]. That is, it is determined whether the acquired celestial position information and the obtained terminal-oriented position information match.

In order to compare the celestial position information and the terminal-oriented position information, the two pieces of information must be configured in the same coordinate system. For example, when the acquired celestial position information is composed of an equator coordinate system and the obtained terminal-oriented position information is composed of a horizon coordinate system, the two pieces of information must be unified and compared with the equator coordinate system or the horizon coordinate system.

Hereinafter, when the acquired celestial position information is configured with an equator coordinate system and the obtained terminal-oriented position information is configured with a horizontal coordinate system, a detailed process of the comparison process [S240] will be described.

4 is an embodiment of a specific process for comparing astronomical location information and terminal-oriented location information.

First, the equatorial coordinates of the acquired celestial bodies are converted into horizontal coordinates [S400]. At this time, it is preferable to use the location information and time information of the terminal obtained in the step [S300].

Then, the celestial position information converted into the horizontal coordinates and the terminal-oriented position information composed of the obtained horizontal coordinate system are compared with each other [S410].

5 is another embodiment of a specific process for comparing astronomical location information and terminal-oriented location information.

First, the terminal-oriented position information consisting of the obtained horizon coordinate system is converted into the equator coordinates [S500]. Then, the terminal-oriented position information converted into the equator coordinates and the celestial position information composed of the equator coordinate system are compared with each other [S510].

The comparison between the celestial position information and the terminal-oriented position information [S410, S510] should compare both azimuth and altitude. In other words, assuming that the celestial sphere is a two-dimensional comparison of both two dimensions.

In addition, the error range may be set by the user. That is, if the user is provided with detailed information and wants to accurately find the location of the desired object, the error range can be set small. If the user wants to quickly find the approximate location of the desired object, the error range can be set large. It is.

If the result of the comparison [S250] is within the error range, it indicates that the terminal direction indicates the input object [S260]. The notification process [S260] may be performed by outputting image information or audio information such as text.

For example, if the user wants a constellation Gemini and finds Gemini by the present invention, the text "Current position: Gemini" is output on the terminal screen or voice information "Current position is Gemini". Can be output through the speaker.

If the result of the comparison [S250] does not exist within the error range, information about the change in the terminal orientation direction required for the comparison result to fall within the error range is output [S270].

For example, if the celestial information currently displayed on the screen of the terminal is a constellation of "Andromeda" instead of the "twin" constellation that the user wants to find, how to change the orientation of the terminal should be displayed on the terminal screen. Is to print information about

That is, the information about the change in the terminal orientation direction is a difference between the celestial position information and the terminal orientation information, and includes the change direction and the amount of change in the terminal orientation direction required for the difference to exist within the error range. It is desirable to.

6 is a diagram illustrating an example of information on a change in the terminal orientation direction output in accordance with the present invention.

6 (a) shows the position of the "Andromeda" constellation and the "Cassiopeia" constellation in the celestial direction, which is obtained according to the present invention, and displays the "Andromeda" constellation and the "Cassiopeia" constellation on the terminal screen. In addition, the user is directed to the direction of the "twin" constellation that the user wants to observe through the screen of the terminal, such as "30 ° east, 20 ° downward." At the bottom of the screen, the current location is provided as text information such as "Current location: Andromeda / Cassiopeia". The current position provided as text information at the bottom of the screen is changed according to the change in the direction of orientation of the terminal.

FIG. 6 (b) is a diagram showing another example of information on the change in the terminal orientation direction output according to the present invention, and provides rough text information “down right” for the “twin” constellation that the user is looking for. At the same time, the current location and the "twin" constellation location are provided as image information so that the user can be intuitively guided.

The information regarding the change in the terminal orientation direction output according to the present invention may be output as image information as shown in FIG. 6, or may be output at the same time or separately as audio information. For example, the voice information "Move 30 ° east and 20 ° downward" may be output through the speaker of the terminal.

7 is a block diagram of a mobile terminal having a celestial direction guidance function according to a preferred embodiment of the present invention.

Referring to FIG. 7, a preferred embodiment of a mobile terminal having a celestial direction guidance function according to the present invention will be described in detail as follows.

The mobile terminal according to the preferred embodiment of the present invention includes a GPS signal receiver 700 for receiving a GPS signal, a mobile communication module 710 for transmitting and receiving data with a mobile communication network, and a direction for recognizing a direction that the terminal is facing. Recognition module 720, an operation recognition module 730 for recognizing the operation of the terminal, a control unit 740, a memory unit 750 and the input unit 760 is configured to include.

The GPS signal receiving unit 700 is a device for receiving a GPS signal to obtain information about the location of the mobile terminal, in addition to the Global Positioning System (GPS) operated by the United States, GLONASS (Global) operated by Russia Navigation Satellite System), a concept that includes GALILEO being developed by the European Union.

As a representative example of the direction recognition module 720, there is a geomagnetic sensor that is mainly used to detect the traveling direction of a vehicle or an aircraft vessel by sensing the magnetic field of the earth.

The principle of the geomagnetic sensor is that the drive coil is wound along a circular ring core, a ferromagnetic material, and the X-coil (coil wound in the X axis) and the Y-coil (wound in the Y axis) orthogonal to the center of the ring core. Coil) and Z-coil (coil wound around the Z axis). At this time, when the magnetic force line is generated in the ring core of the drive coil, the induced voltage obtained by combining the magnetic force and the geomagnetic generated in the ring core is measured through the X-coil, the Y-coil and the Z-coil, and the potential difference of the measured induced voltage The direction is detected by. Since the value measured by the geomagnetic sensor may change due to a temperature change or other magnetic material in the surroundings, compensation may be required.

As described above, the geomagnetic sensor used in the present invention preferably uses three axes of X-coil, Y-coil and Z-coil, but may use two axes.

Representative examples of the motion recognition module 730 is an acceleration sensor or a gyro sensor. Accelerometer detects dynamic forces such as acceleration, vibration and shock, and uses the application principle of inertial force, electric deformation and gyro.

Looking at the basic principle of the acceleration sensor, the acceleration is generated when the object moves, and the integration of the measured acceleration twice with respect to time is the moving distance. To measure front, back, top, bottom, left and right, three-axis acceleration sensor is needed.

Acceleration sensor can be classified into the following three according to the operation principle.

First, it is tropical. There is a gas mass inside the sensor, which is a heating element and heated air, but when there is an external movement, the gas mass moves. At this time, the sensor detects the sensor by changing the temperature emitted by the heating element.

Second is the Piezoresistive method. If the structure itself is inclined in accordance with the acceleration direction, the resistance value changes when the structure itself is inclined according to the acceleration direction, thereby changing the value of the current flowing through the structure and recognizing the change in current as an acceleration.

Third is the capacitive approach. This method uses mass inertia by putting a solid object that is a mass of mass inside the sensor. If no force is applied from the outside, the capacitance has a constant value, but if a force is applied in one direction here, the internal solid moves in the opposite direction to the direction of the force and the internal capacitance changes in this process. The acceleration is measured by calculating the changed capacitance value.

The memory unit 750 stores a predetermined program for controlling the overall operation of the mobile terminal, and data input and output and various data processed when the overall operation of the mobile terminal is performed by the controller 740. Save it. In particular, the memory unit 750 stores celestial information including celestial position information of the celestial body that matches the celestial body name.

In addition to the celestial position information, the celestial information may include an image of a celestial body, a legend related to a star or a constellation, an animation, a flash, a video, and the like.

The input unit 760 is a device for receiving various information or commands from a user, such as a keypad or a touch screen having various keys. In the present invention, the input unit 760 receives a celestial name from the user.

The controller 740 manages the overall operations of the mobile terminal. In particular, the controller 740 controls the GPS signal receiver 700, the mobile communication module 710, the direction recognition module 720, the motion recognition module 730, the memory unit 750, and the input unit. It is preferable to include an acquirer 745 and an information processor 747.

The information acquisition unit 745 obtains location information of a terminal, a direction including a direction and an altitude to which the terminal is directed (hereinafter, referred to as a terminal orientation direction), and time information.

In addition, the information processing unit 747 includes celestial position information indicating a celestial position of a celestial body corresponding to the celestial body name received from the input unit 760 and terminal-oriented position information indicating a celestial position indicated by the terminal orientation direction. Compare and output information about the change in the terminal orientation direction required for the comparison result to fall within a predetermined error range.

On the other hand, the information processing unit 747 obtains the celestial position information with reference to the celestial information stored in the memory unit 750, the terminal position information received from the information acquisition unit 745, the terminal orientation information, and the like. The terminal-oriented location information is obtained using time information.

In addition, the error range may be adjusted by the user.

The celestial position information and the terminal-oriented position information, respectively, may be made of any one of the various coordinate systems indicating the position of the celestial body. Hereinafter, a description will be given of the case where the celestial position information is made of an equator coordinate system and the terminal-oriented position information is made of a horizon coordinate system.

Hereinafter, the operation of acquiring the terminal location information, the terminal orientation information, and the time information of the information acquisition unit 745 will be described in detail.

The location information of the terminal may be obtained using a GPS signal received through the GPS signal receiving unit 700 or a mobile communication base station system parameter received through the mobile communication module 710. As a representative example of the location information, there is latitude / longitude information. Meanwhile, the location information of the terminal may be directly input by the user through the input unit 760.

The time information may be obtained using a GPS signal received through the GPS signal receiving unit 700 or a mobile communication base station system parameter received through the mobile communication module 710. In addition, like the location information of the terminal, the time information may also be directly input from the user through the input unit 760.

In addition, the terminal-oriented direction information including the direction and the altitude is preferably obtained by measuring the change amount of the direction and the altitude by using the direction recognition module 720 and the motion recognition module 730.

On the other hand, it is preferable that the said direction information contains the information about all directions and altitudes of three dimensions. The reason why the direction information includes all directions and altitude information in three dimensions is not limited to the sky that can be observed from the user's or the terminal's current location only by the user's naked eye. For example, even if the terminal orientation indicates the other side of the earth, the user can observe the sky on the other side of the earth through the terminal.

Hereinafter, a case in which the direction recognition module 720 is a geomagnetic sensor and the motion recognition module 730 is an acceleration sensor will be described.

For example, the information acquisition unit 745 uses the geomagnetic value received from the direction recognition module 720 and the acceleration value received from the motion recognition module 730 to determine the direction and altitude of the terminal. Obtains and outputs direction information to be included.

Here, azimuth and altitude are concepts that encompass all of the terms used in each coordinate system for indicating the position of the object. For example, in the equatorial coordinate system, the orientation becomes right ascension, and the altitude is declination.

On the other hand, the information acquisition unit 745 can measure the direction and altitude of the terminal using only the geomagnetic value received from the geomagnetic sensor, but from the acceleration sensor to improve the acquisition speed and accuracy of the direction information It is preferable to simultaneously use the received acceleration value.

In addition, the information acquisition unit 745 may directly receive specific direction information including azimuth and altitude from the user through the input unit 760.

In addition, in order for the information processing unit 747 to compare the celestial position information and the terminal-oriented position information, the two pieces of information must be configured in the same coordinate system. Therefore, when the celestial position information is composed of the equator coordinate system and the terminal-oriented position information is composed of the horizon coordinate system, it is necessary to unify the coordinate system into the equator coordinate system or the horizon coordinate system.

First, it is a case of unifying the horizon coordinate system. The information processing unit 747 converts celestial position information consisting of the equator coordinate system into a horizontal coordinate system using the obtained position information and time information of the terminal, and comprises the converted celestial position information and the acquired horizontal coordinate system. Compare terminal-oriented location information.

Second is the case of unification with the equator coordinate system. The information processor 747 converts the terminal-oriented position information of the obtained horizon coordinate system into equator coordinates, and compares the fraud-converted terminal-oriented position information with celestial position information composed of the equator coordinate system.

On the other hand, the information about the change in the terminal orientation direction output by the information processing unit 747 is a difference between the celestial position information and the terminal orientation position information, and the terminal orientation required for the difference to exist within the error range. It is preferable to include the direction of change of the direction and the amount of change.

In addition, the information processing unit 747 may perform an operation of reading and outputting celestial information corresponding to the terminal orientation information from the memory unit 750 as the terminal orientation direction changes. This is to inform the user where the celestial position indicated by the direction of the current terminal by outputting information about the object indicated by the direction of orientation of the terminal when the user finds the desired position of the object. .

The output method of the astronomical information may vary. For example, an image of a star or a constellation stored in the memory unit 750 may be displayed, or related text information may be displayed or output as a voice. It can also be output in the form of video, animation, flash, etc.

In addition, when a celestial object input by a user is located at a celestial position indicated by the orientation direction of the terminal (that is, when the comparison result is within an error range), the information processing unit 747 determines that the terminal orientation direction is different. It is preferable to perform an operation for notifying the received celestial body.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The effects of the celestial direction guidance method and the mobile terminal having the celestial direction guidance function according to the present invention described above are as follows.
