Description

Constellation information provision service using mobile communication terminal. {Providing Star Constellation Service using Mobile Terminal}

1 is a flowchart illustrating a constellation information providing service method using a mobile communication terminal of the present invention.

In the present invention, a mobile communication terminal is a generic term for all devices having a wireless data transmission / reception function such as a mobile phone, a PDA equipped with a wireless terminal module, a laptop equipped with a wireless LA N or a wireless terminal module, and a game machine equipped with a wireless data transmission / reception function. do.

The present invention relates to a method of acquiring constellation information using an orientation sensor and an angle sensor mounted on a mobile communication terminal and displaying the same on a mobile communication terminal.

Since ancient times, the constellations of the night sky have given people many dreams and stories. It was used as an astrology, as a means of foraging the future of individuals, and as an influence on the state management of rulers. It has been used for navigation of ships and airplanes and is still leading to various space development attempts around the world. Efforts have been made to recreate constellations that can only be seen at night anytime and anywhere. Due to the development of technology, programs have been developed to view constellations on computers. But it's only visible on computers with the program, but not portability. Also, with the development of the Internet, if the constellation program is installed on the server and can be connected to the Internet without any space limitation by using the client computer, the constellation can be viewed using the computer regardless of day and night anywhere in the world. However, this technique did not completely overcome the space limitations. Recently, due to the development of mobile communication technology, spatial restrictions can be completely eliminated when owning a mobile communication terminal. Some methods of providing constellation information using a mobile communication technology have been invented, and one of them is a method of displaying constellation information by mounting a program corresponding to a client in a mobile communication terminal. This technique overcomes the space limitations but still requires that the user have some knowledge of the constellations in advance. People who want to use constellation information do not want to check all the information of all the constellations, and tend to want to obtain specific information about a certain constellation immediately at a specific time. In other words, the problem of accuracy and instantaneous constellation information occurs. In the case of searching for constellation information using the Internet, the server can transmit and display various information about the constellation to the client only if the constellation to be searched is known in advance. Although the program is written in a menu, users can use constellation information even if they do not have prior knowledge, but this is an inefficient way of learning, such as memorizing an English word, which randomly overturns an English dictionary when memorizing English words. New technologies have been invented to address the accuracy and immediateness of this information. Shoots the constellation of the night sky by using the camera mounted on the mobile communication terminal, and transfers the photographic information of only part of each star that constitutes the constellation by the resolution of the camera, the light leaking from the surrounding buildings, and the clouds of the night sky to the server. By using the algorithm separately invented by the server to calculate the constellation information and transmits it back to the mobile terminal, it is displayed. But this method has a time limit that must be night. In addition, it is difficult to obtain sufficient constellation pictures necessary for extracting constellation information in the night sky of a large city where air pollution is severe. In addition, a program of high difficulty called pattern matching should be used, and the time consumed by the user has to inconvenience the calculation time delay other than the transmission delay in order to obtain constellation information.

As described above, when the constellation information is to be used, the accuracy of the information, immediate response, spatial limitation breaking, and temporal limitation breaking are very important factors. The present invention consists of the sum of the cross-sectional pieces of the sky and obtains the cross-section of the sky looking at the position of the observer observing the constellation, the direction of the eye, and the angle of the eye to the mobile communication terminal, respectively, and corresponds to the observed date / time. By displaying the cross-sectional constellation information on the mobile communication terminal to implement a constellation information providing service that overcomes the accuracy, instantaneous, temporal, and spatial limitations.

In order to implement this, the present invention uses a database constituting the cross-sectional information of the sky, and the user directly inputs the latitude and longitude coordinates of the user, the angle to be observed, and the direction in the mobile communication terminal, or uses the GPS installed in the mobile communication terminal. Coordinate information can be obtained by using latitude and longitude coordinates, and information about the degree of inclination can be obtained through a sensor that can grasp the angle of the terminal. This information is collected and sent along with the date / time information to the server, and the server uses this information to transmit the constellation information of the sky section to the mobile terminal through a simple calculation that infers the sky section viewed by the user. The purpose is to provide a service that provides.

In order to achieve the above object, the present invention provides a first step of obtaining the latitude and longitude coordinates of the terminal using a mobile communication terminal, two steps of obtaining the angle of the terminal, three steps of obtaining the direction coordinates of the terminal, latitude and longitude coordinates, angle, and direction coordinates. , 4 steps of delivering date / time information to the server, 5 steps of calculating display information from the server, 6 steps of the server transmitting relevant information to the mobile terminal and displaying it on a display device such as an LCD. It is composed.

In the first step of obtaining the latitude and longitude coordinates of the terminal, the latitude and longitude coordinates are calculated by the program installed in the mobile communication or provided by the mobile communication service company using the GPS embedded in the mobile communication terminal or separately attached to the outside of the mobile communication terminal. It is characterized by obtaining the latitude and longitude coordinates using a location based service (LBS). In addition, even if a mobile communication terminal is not equipped with a GPS, even if equipped with a GPS, the user uses a constellation service on any particular latitude and longitude, and the user directly inputs the latitude and longitude coordinates.

In the second step of obtaining an angle of the mobile communication terminal, the angle of the mobile communication terminal is automatically calculated using an angle sensor installed in the mobile communication terminal, that is, the gaze angle of the constellation observer is calculated. When the angle sensor is not mounted on the mobile communication terminal, the user directly inputs the angle of the mobile communication terminal.

In the third step of obtaining the direction coordinates of the terminal, the direction coordinates of the mobile communication terminal are automatically calculated by using the direction sensor installed in the mobile communication terminal. When the direction sensor is not installed in the mobile communication terminal, the user directly inputs the direction of the mobile communication terminal.

 In the fourth step of transmitting the latitude, longitude, direction, and date / time information to the server, the wireless Internet connection is established, the server providing the constellation information service is connected, and the user authentication is performed to check the service usage authority. Latitude and longitude coordinates, angles, direction coordinates is characterized in that for transmitting from the mobile terminal to the constellation information service providing server.

In the fifth step of calculating display information on the server, the server is equipped with a database on a combination of cross sections of the sky, and is equipped with a function of calculating a specific cross section of the sky by receiving latitude and longitude coordinates, angles, and direction coordinates. The specific cross section of the sky may be one of a set of sky sections previously divided into a predetermined size, and may be variable within a constant radius about a specific point in the sky calculated by the latitude, longitude, and coordinates of the mobile terminal user. It may be a cross section of the sky. This server is characterized by mounting the database related to the constellations.

 In step 6, in which the server transmits related information to the mobile communication terminal and the mobile communication terminal implements the information on a display device such as an LCD, it is possible to select whether to transmit constellation information on one or more selected sky sections. When the constellation information in a plurality of sky sections is transmitted, the feature of selecting the sky section in the mobile communication terminal and the constellations existing in the selected sky section are all displayed on one screen of the mobile communication terminal and are also present in the selected sky section. If a constellation name is provided in a menu format and a specific constellation name is selected, the selected constellation is displayed to be distinguished from other constellations or is displayed on a separate screen only for the selected constellation.

As described above, according to the present invention, even if the user has no prior knowledge of the constellation, the information on the constellation can be immediately obtained without using the mobile communication terminal in the same way as the human behavior that looks at the stars in the sky without time and space limitation. Providing a way to explore can be expected to enhance the convenience for the user and increase the utilization rate due to the increased user convenience for the constellation service provider.
