Location feature description method, system and computer program product

The present invention relates to a positioning method and system, and more particularly to a location feature description method, system and computer program product.

In order to cope with the busy life pace of modern people, all kinds of portable electronic devices that do not occupy space and are convenient to carry are also innovated. Take the Personal Digital Assistant (PDA) mobile phone as an example. It not only has the functions of the traditional communication device, but also allows users to write files, send and receive emails, and browse through its built-in window operating system. Internet, or use instant messaging software. That is to say, such a portable electronic device can be used not only to make a call, but also to provide various functions like a small personal computer. With the advancement of wireless network technology, the use of these functions is no longer limited by time and space. For modern people who are efficient in everything, this device has become one of the indispensable tools in life.

In addition to the above functions, many portable electronic devices are equipped with a Global Positioning System (GPS) or an Assisted Global Positioning System (AGPS) to receive satellite positioning signals at any time.

FIG. 1 is a flow chart of a method for describing a location feature according to an embodiment of the invention. Please refer to Figure 1. The embodiment is applicable to a communication device having a communication and positioning function, such as a mobile phone, a smart phone, a personal digital assistant (PDA) mobile phone or a car computer (Car PC), and the communication device is configured, for example. Global System for Mobile Communication (GSM) system, Personal Handy-phone System (PHS), Code Division Multiple Access (CDMA) system, Wireless Fidelity (Wireless fidelity) , Wi-Fi) system or wireless communication system such as Worldwide Interoperability for Microwave Access (WiMAX) system, and has wireless communication function for receiving or broadcasting calls. The implementation steps of this method are detailed below:

In this embodiment, when the user uses the communication device to make a call, the user is provided with an easy way to inform the other party of the call. Wherein, when the communication device enters the call mode, a call channel is established (step S110). The step of entering the call mode may be that the user first dials out or answers the call through the function of making/receiving the call of the communication device. In detail, the communication device first receives the user's incoming call operation or the outgoing call operation, and enters the call mode when the call is answered or dialed out, or when the outgoing call is turned on.

When the communication device enters the call mode, the user can talk to the connected object. During the call, as mentioned above, the user may need to notify the other party of the geographical location of the current location, and this function can be activated through the hardware or software preset on the communication device. The above hardware may be a hot key on the communication device; the software may be a virtual button that appears on the touch panel during the call. The above-mentioned input mode can be designed by a person having ordinary knowledge in the technical field according to the use requirements, and the embodiment of the present invention is not limited thereto.

In an embodiment, after the communication device receives the input operation of the user, the positioning function of the communication device is activated to locate the communication device to obtain the positioning data of the communication device (step S120). The positioning function can be completed by using a positioning chip or a module in the communication device, using a Global Positioning System (GPS) or an Assisted Global Positioning System (AGPS).

In another embodiment, the communication device can activate the positioning function of the communication device to locate the communication device before entering the call mode, and obtain the positioning data of the communication device at any time.

Generally, after the GPS or AGPS performs the positioning function of the spatial location of the current location, the positioning data such as the latitude and longitude coordinates of the location can be obtained. In this embodiment, the location data is processed, for example, by referring to a geographic information database (for example, an electronic map) stored in the communication device in advance, and querying the location feature around the location where the location data is located (step S130) to find out More accurate geographic information.

In detail, the positioning data such as the latitude and longitude coordinates are not the geographical description information that we know everyday, and it is difficult to judge the direction and location of the user. In addition, the latitude and longitude coordinates may not correspond to specific geographic information on the geographic information database. Therefore, in this embodiment, the reverse geocoding (First) can be used to convert the positioning data into an address, and further cooperate with the geographic information database to query the more specific location features near the address as a reference for the user.

There are two types of more specific location features: the first is to query the "road name" near the address as the location feature; the second is to query the "landmark" around the address as the location feature. Of course, there may be more than one related "road name" or "landmark". Therefore, the result of the location data query may include one or more location features, which is not limited herein.

After obtaining the location features, the communication device can further group them into a complete location feature description (step S140). The process of compiling the location features into the location feature description may be performed by using a software having an operation and editing function on the communication device, and further positioning the location data (for example, latitude and longitude coordinates) of the location and the location and distance of the location features. Compare and calculate, and then describe the gap between the two to clearly inform the user where they are.

For example, when the selected location feature is a landmark: "Ren Patriotic", the detailed description of the location of the current location in the front of the patriotic center can be obtained through the location description step of the present embodiment. By being able to clearly understand the geographical location of the location by the location and location difference of the location features, it is not just the latitude and longitude figures presented by the location data.

In particular, the location features queried in step S130 may be combined into location characterizations of different descriptions according to different types (eg, "road names" or "landmarks"). In this regard, the location feature description will be further exemplified by other embodiments, which will be further exemplified by two different types of location features, "road name" and "landmark".

Finally, the communication device can convert the location feature description obtained in step S140 into voice broadcast data, and output the voice broadcast data through the call channel (step S150). For example, the voice synthesizing software of the communication device can be converted into a voice file format readable by a communication device such as ".3gp" by the above-mentioned example "the current location is 12 meters in front of Ren Paizhong", and A good call channel is established and broadcast to the other party of the call, so that the user and the other party to the call can hear the result of the geographical location at the same time. That is to say, the embodiment provides a call mode in which a geographical location can be immediately queried during a call, and a voice broadcast response is obtained at the moment, which can avoid the call in the general call, and then dial the call after performing the location query. Inconvenience; or during the call, the location query, and let the other party wait online, in addition to even inconvenient to remember or record the inconvenience of the query results.

In addition, the search results and voice messages of the positioning can be additionally designed and stored, so that the user can still repeatedly view and play the positioning voice message in the future. The implementation steps of the above detailed description are familiar to those skilled in the art, and the embodiments of the present invention are not described herein.

Next, in another embodiment, the description method of the location feature of the present invention is completed by exemplifying the description manners of two different location features of "road name" and "landmark".

For example, a method for describing a geographical location by using a “road name” is a flowchart of a method for describing a location feature characterized by “road name” according to another embodiment of the present invention. The “road name” may include, for example. The information related to the road, such as the name of the road, the intersection, the fork, and the like, is not limited herein. 3 is a schematic diagram of a geographic information database displayed by a communication device. Please refer to Figure 2 and Figure 3 at the same time. In the embodiment of the present invention, it is assumed that the user wants to query the current location during the call, and when he walks through point 3A in FIG. 3, presses the query hot key on the communication device, and continues to go to point 3B. . After receiving the query input request of the user, the communication device then uses the positioning function of the GPS system in the communication device to obtain the positioning data such as the latitude and longitude coordinate of the 3A point, or activates the positioning function of the GPS system in the communication device at this time, Positioning data such as latitude and longitude coordinates of point 3A is obtained (step S210).

Next, the communication device converts the location data into an address by using reverse geocoding (step S220), and the result is, for example, the address "No. 128, Section 3, Zhongxiao East Road" shown in FIG.

Then, the communication device can refer to the geographic information database, and find out the current road where the communication device is currently located according to the address, and the previous road and the next road that are located before and after the address of the current road and intersect with the current road (step S230). Taking Figure 3 as an example, the address that the communication device has queried is "No. 128, Section 3, Zhongxiao East Road", and then the first and second roads intersected by this address are "Jianguo South Road" and "Fuxing South Road". At the same time, because the gate number of the address increases in a fixed direction, for example, here from west to east, it can be defined that the "Jianguo South Road" with a smaller address number in the road interlaced with the current road "Zhongxiao East Road three segments" is The former road and the larger address of the "Fuxing South Road" are the latter road. In addition, in another embodiment of the present invention, the positioning data of the user can be continuously detected to determine the forward direction of the user (for example, from 3A to 3B in FIG. 3, the forward direction is determined by the west. Go east) and use this direction to decide which is the previous or the next road. That is, the embodiment of the present invention does not limit the definition of the roads before and after.

Thus, the communication device can retrieve the road names of the current road, the previous road, and the next road as the location features (step S240). Taking Figure 3 as an example, the location feature here is “No. 128, Section 3, Zhongxiao East Road”, “Jianguo South Road” and “Fuxing South Road”.

After the location features are extracted, the location features can then be grouped into location characterizations to provide an orientation relationship and accurate geographic information between the user's current location and location characteristics. This step can be subdivided into the following two substeps.

First, the communication device is described on the current road and between the previous road and the next road (step S250). For example, the group description (1) is: "The current location is at No. 128, Section 3, Zhongxiao East Road, located in Jianguo. Between South Road and Fuxing South Road."

Next, the traveling direction of the communication device is defined, and the communication device is described on the left or right side in the traveling direction according to the address (step S260). In order to define the direction of travel of the communication device, the communication device can continue to locate the communication device or locate the communication device again within a predetermined time interval. This embodiment does not limit its scope. Assume that the user just goes to point 3B in Figure 3, so that the location data of point 3B can be obtained, and by analyzing the location data of 3A to 3B, the direction of travel of the communication device on the geographic information database can be defined as : "From Jianguo South Road to Fuxing South Road."

It should be noted that when the communication device does not have any displacement or the displacement amount is too small within a predetermined time interval, so that the judgment result of the travel pitch is stationary, the communication device can also pop up (Pop-Up) window mode. Ask the user where to go; or let the user move on again to re-start the positioning system to calculate the direction of travel. In addition, the remaining feasible embodiments may be used to confirm the definition of the direction of travel of the communication device, which is not limited herein.

After defining the direction of travel, it is then possible to determine from the address that the communication device is located to the left or right of the direction of travel as a location feature description (2). The step of determining whether the communication device is located on the left or the right side of the traveling direction is to first retrieve the number in the address. For example, if the address here is "No. 128, Section 3, Zhongxiao East Road", the number is "128". Then, based on the direction of travel, depending on whether the number is odd or even, it can be determined that the communication device is located on the left or right side of the current road. For example, the number obtained here is "128", which is an even number; the current direction of travel is: "From Jianguo South Road to Fuxing South Road." At this point, the judgment of the geographic information database will result in the "right side" of the even number in the direction of travel. Therefore, the group description (2) is: "From Jianguo South Road to Fuxing South Road, on the right side of the third section of Zhongxiao East Road."

Finally, after the location feature descriptions (1) and (2) are composed into a complete sentence, the voice conversion software can be used to convert the location feature descriptions (1) and (2) into voice broadcast data and through the call channel. The voice data is output (step S270). Therefore, at the moment of the broadcast, the caller or the user and the other party can hear the voice broadcast information: "The current location is at No. 128, Section 3, Zhongxiao East Road, between Jianguo South Road and Fuxing South Road, from Jianguo South Road to Fuxing South Road. Walk, on the right side of the third section of Zhongxiao East Road." According to this, the calling party can judge the location of the user according to the road information in the voice broadcast data that is heard.

On the other hand, a method of describing a geographical location by "landmark" is taken as an example. FIG. 4 is a flowchart of a method for describing a location feature featuring "landmark" according to another embodiment of the present invention, and "landmark" may include For example, landmarks, attractions, buildings, stations, stop signs, and the like, the embodiments of the present invention are not limited herein. Figure 5 is a schematic diagram of a geographic information database displayed by a communication device. Please refer to Figure 4 and Figure 5 at the same time. First, when the user goes through point 5A in Fig. 5, the query hotkey on the communication device is pressed. After receiving the query input request from the user, the communication device then uses the positioning function of the GPS system in the communication device to obtain the positioning data such as the latitude and longitude coordinates of the 5A point, or activates the positioning function of the GPS system in the communication device at this time, Positioning data such as latitude and longitude coordinates of point 5A is obtained (step S410).

Then, the communication device converts the positioning data into an address by using reverse geocoding, and the address of the converted 5A point is, for example, "No. 228, Section 4, Zhongxiao East Road", and then the geographic information database can be queried in the geographic information database. The landmark is taken as a location feature (step S420). The communication device, for example, centers on the address and queries the geographic information database for a landmark within a certain range of the circle (for example, within 100 meters).

Taking Figure 5 as an example, if the landmark that the communication device has queried is "MRT National Memorial Hall", this landmark can be used as a location feature. Of course, if the communication device finds multiple landmarks within the set range, the plurality of landmarks may be taken as the location feature at the same time, or the nearest or most obvious landmark may be used as the location feature. Set limits.

After the location features are extracted, the location features can then be grouped into location characterizations to provide an orientation relationship and accurate geographic information between the user's current location and location characteristics. This step includes the following two substeps.

First, the communication device determines the direction of travel from the landmark to the communication device, and calculates the distance between the communication device and the landmark in the direction of travel (step S430). Taking FIG. 5 as an example, the communication device can use the positioning data of the 5A point obtained in step S410 and the positioning data of the "Municipality Memorial Hall Station" to determine the direction of travel from the "MRT National Memorial Hall" to point 5A. From west to east. At this point, together with the geographic information database, it can be calculated that the distance between the 5A point and the "MRT National Memorial Hall" in this direction of travel is 50 meters.

Next, the communication device can describe that the position of the system is at the calculated distance from the landmark to the determined traveling direction (step S440). At this time, after joining the full name of the landmark "MRT National Father Memorial Hall", the complete location feature description is, for example: "Currently at No. 228, Section 4, Zhongxiao East Road, the MRT National Memorial Hall is about 50 meters from west to east. Where."

Finally, the communication device can convert the location feature description into voice broadcast data by using the voice conversion software, and output the voice data through the call channel (step S450). According to this, the calling party can judge the location of the user according to the landmark information in the voice broadcast data that is heard.

It should be noted that, except for the "road name" and "landmark" as the location features to describe the geographical location of the current location, any person having ordinary knowledge in the technical field may disclose other objects or methods after the embodiment of the present invention is disclosed. For description. The present invention is not limited as long as the appropriate location characteristics can be selected and the geographical location of the current location can be fully described.
