Method, system and computer program product for indicating the orientation of interest points

The present invention relates to a method and system for indicating a point of interest, and more particularly to a method, system and computer program product for indicating the orientation of a point of interest in a three-dimensional manner.

In recent years, with the continuous evolution and improvement of electronic technology and communication technology, electronic devices such as mobile phones (Cellular Phones) and personal digital assistants (PDAs) that do not occupy space and can be carried around are also being introduced. The portable electronic devices on the market do not integrate multiple functions to enhance their competitiveness. In addition to the general camera, call and Internet functions, they now have positioning systems such as Global Positioning System (GPS), electronic maps and navigation. The system is also integrated into the handheld communication device. Users can grasp their position by GPS anytime and anywhere, and also use the navigation system planning and guidance to find the best route to get to the destination quickly and safely.

GPS is a positioning technology that combines satellite and wireless communications to provide accurate positioning, speed and time information. The GPS can be combined with an electronic map, and the positioning information obtained by positioning it can be displayed on the electronic map to provide the user with the current location. The electronic map also includes information that records a number of Point Of Interest (POI) information that allows the user to view the location of the map while viewing the restaurant, landmark, or attraction near the location.

In order to clarify the content of the present invention, the following specific examples are given as examples in which the present invention can be implemented.

First embodiment

1 is a block diagram of an indication system for a point of interest orientation in accordance with a first embodiment of the present invention. Referring to FIG. 1 , the indication system 100 of the interest point orientation in the embodiment is, for example, configured in a mobile device, a smart phone, a personal digital assistant, a personal digital assistant mobile phone or a mobile computer, and the pointing system 100 includes a positioning unit. 110. The point of interest recording module 120, the orientation detecting unit 130, the computing unit 140, and the point of interest flag display module 150 are described as follows:

The positioning unit 110 is, for example, a Global Positioning System (GPS), an Assisted Global Positioning System (AGPS), or a communication positioning system for detecting a positioning position where the mobile device is located. The communication positioning system is, for example, a Global System for Mobile Communication (GSM) system, a Personal Handy-phone System (PHS), and Code Division Multiple Access (CDMA). System, Wireless Fidelity (Wi-Fi) system, Worldwide Interoperability for Microwave Access (WiMAX) system, Radio Repeater or Radio Broadcaster.

The point of interest record module 120 is, for example, a database in which information about points of interest is recorded, including the name of the point of interest, the latitude and longitude coordinates, the address, the phone, the photo, the date of the photo, the time, the text file, and the audio file. , one of or a combination of video files and ratings.

The orientation detection unit 130 is, for example, a digital compass that can be used to detect a second orientation that is oriented by one of the planes of the mobile device. Wherein, the plane of the mobile device is the reverse side of the screen plane viewed by the user. In detail, when the user uses the mobile device, the screen is generally directed toward himself to view the content displayed on the screen. The second orientation detected by the embodiment is the orientation that the user faces, that is, the orientation of the opposite side of the screen plane.

The computing unit 140 is, for example, a processor that compares the positions of the points of interest recorded by the point of interest recording module 120 with the positioning positions of the mobile device one by one, and calculates the first orientation of each point of interest with respect to the mobile device. The first orientation represents the relative orientation of the point of interest on the electronic map relative to the location of the mobile device (eg, the point of interest is located to the southeast of the mobile device), and the second orientation detected by the orientation detecting unit 130 is It is the absolute orientation that the plane of the mobile device faces (for example, the mobile device faces north), and the definitions of the two are different. A simple example will be given below to illustrate the relationship between the first orientation and the second orientation.

2 is a schematic diagram of an electronic map according to a first embodiment of the present invention. Referring to FIG. 2, the electronic map 200 includes a positioning location 201 for displaying the mobile device and a point of interest 202. The orientation pointed by the arrow 203 is the first orientation of the point of interest 202 relative to the positioning position 201, and the orientation pointed by the arrow 204 is the second orientation of the mobile device.

In addition to calculating the first orientation of the point of interest relative to the location of the mobile device, the computing unit 140 calculates the relative orientation of the first orientation relative to the second orientation in the three-dimensional space. Taking FIG. 2 as an example, if the second orientation (the arrow 204 is pointed) is regarded as the 12 o'clock direction, the relative direction of the first orientation (the arrow 203 is pointed) relative to the second orientation is 2 o'clock. .

The point of interest flag display module 150 displays the flags of the points of interest recorded by the point of interest recording module 120 in a three-dimensional manner based on the second orientation described above, so that the flags indicate that the points of interest are The relative direction in the three-dimensional space with respect to the second orientation. In detail, the point of interest flag display module 150 is based on, for example, an orientation toward the inner side of the screen plane (ie, the second orientation), and in a three-dimensional manner according to the relative direction of the respective points of interest with respect to the inner side of the screen plane. To indicate the signs that point to the various points of interest. The flag is, for example, in the form of a solid arrow pointing to the relative direction of the point of interest relative to the inner side of the screen plane, and may also display related information of the point of interest, such as the name and distance of the point of interest.

For example, FIG. 3 is a schematic diagram of a point of interest flag according to a first embodiment of the present invention. Referring to FIG. 3, the point of interest flag display module 150 displays, for example, a virtual three-dimensional space on the screen 300, and displays the signs 301 to 307 pointing to the relative directions of the points of interest based on the orientation inside the screen plane, for example, for example. The sign 307 indicates that the convenience store is located 15 meters to the right rear of the direction in which the user faces, and so on.

In addition to the manner in which the above-described embodiments display the logo, the POI display module 150 may also use different colors or styles of markers to indicate the orientation of the point of interest depending on the location detection mode. For example, when the positioning position of the mobile device is measured by the global positioning system or the auxiliary global positioning system, the point of interest flag display module 150 displays the point of interest flag with a white arrow (the background is black); When the position is measured by the communication positioning system, the red flag is used to display the point of interest mark, thereby reminding the user whether the measured position is accurate (generally, the position determined by the communication positioning system is less accurate) ).

In addition, after the point of interest flag display module 150 displays the flag indicating the orientation of the point of interest, the operation unit 140 may perform the corresponding point of interest flag according to the user's selection operation of the point of interest flag received by the mobile device. The function is, for example, displaying relevant information of the point of interest corresponding to the point of interest mark, or starting a navigation function to plan a route to the point of interest corresponding to the point of interest mark.

It is worth mentioning that before or after the display of the point of interest sign, the mobile device can also display a setting interface of the search range according to the operation of the user, so that the user can set the search range of the point of interest. After the computing unit 140 receives the search range set by the user, the interest points located in the search range are searched for among the points of interest recorded by the point of interest recording module 120, centering on the positioning position of the mobile device. A flag indicating the searched point of interest is displayed on the screen.

For example, FIG. 4 is a schematic diagram of a search range setting interface according to a first embodiment of the present invention. Referring to FIG. 4, the setting interface 400 of the present embodiment takes the positioning position 401 of the mobile device as a center point, and sets a range within a radius of 700 meters as a search range of the point of interest. The setting interface 400 displays, for example, an adjustment rod 402 for the user to expand or narrow the search range by dragging the adjustment rod 402 left and right.

In addition to setting the search range, the mobile device can also display a setting interface of the type of interest points according to the operation of the user, which includes a bar listing all the types of interest points for the user to set the points of interest corresponding to the signs displayed by the mobile device. kind. For example, the user can set the mobile device to display only the two types of interest points of the "convenience store" and the "coffee shop" to exclude other types of interest points, so that the logo displayed by the mobile device meets the user's needs. Not too messy.

For example, FIG. 5 is a schematic diagram of a point of interest type setting interface according to a first embodiment of the present invention. As shown in FIG. 5, the setting interface 500 of the embodiment lists the types of interest points such as a coffee shop, a fast food restaurant, a convenience store, a parking lot, a shopping center, and the like, and provides a selection box for the user before the interest point types. Check it. Among them, after the user selects the coffee shop, the fast food restaurant and the parking lot and presses the OK button, the mobile device displays the signs belonging to the points of interest of the points of interest.

In summary, the present embodiment can assist the user to go to the point of interest through the most familiar and intuitive sign of the average person. The user can determine which direction to go to the point of interest without having to compare the position and direction on the electronic map.

In conjunction with the above-described indication system 100, the present invention further provides a method for indicating the orientation of the point of interest, and an embodiment will be described below to describe the detailed steps of the method. Figure 6 is a flow chart showing a method of indicating the orientation of a point of interest in accordance with the first embodiment of the present invention. Referring to FIG. 1 and FIG. 6 simultaneously, first, the mobile device detects the location of the location (step S602). The mobile device, for example, uses the positioning unit 110 such as a global positioning system, an assisted global positioning system or a communication positioning system to position itself to detect the positioning position where it is located.

Next, the first orientation of the at least one point of interest with respect to the location of the location is obtained by the mobile device (step S604). Specifically, the mobile device reads, by using the computing unit 140, the location of the recorded point of interest from the point of interest recording module 120, and compares it with the location of the mobile device, respectively, to calculate the points of interest relative to the action. The first orientation of the location of the device.

Further, the second orientation of the plane of the mobile device is detected by the mobile device, and the plane is, for example, the reverse of the screen plane of the mobile device display flag (step S606). The mobile device detects the second orientation facing the plane of the mobile device by using the position detecting unit 130 such as a digital compass to serve as the orientation facing the user.

Finally, the mobile device indicates the signs of the points of interest in a three-dimensional manner based on the second orientation, such that each of the markers indicates the relative orientation of the first orientation of the corresponding point of interest in the three-dimensional space relative to the second orientation. (Step S608). In general, when viewing a screen, the user intuitively assumes the orientation toward the inside of the plane of the screen. Therefore, the mobile device 140 sets the second orientation to the inner side of the screen plane by using the computing unit 140, thereby calculating the relative direction of each point of interest with respect to the inner side of the screen plane, so that the point of interest flag display module 150 is in the virtual three-dimensional space. The sign displayed in can point to the relative direction of the point of interest relative to the inside of the screen plane.

It is worth mentioning that when displaying the point of interest sign, the mobile device can also provide the search range and type of the user's set point of interest according to the user's operation, so as to display the point of interest of the user on the screen. The related content has been described in the previous embodiment, and details are not described herein again.

In addition to the above-described manner of simply indicating the orientation of the point of interest by a solid arrow, the present invention also includes combining these three-dimensional arrows into a three-dimensional street sign to indicate the orientation of the point of interest. Hereinafter, the steps of the indication method of the point of interest of the present invention will be described with reference to an embodiment of the above indication system 100.

Second embodiment

Figure 7 is a flow chart showing a method of indicating the orientation of a point of interest in accordance with a second embodiment of the present invention. Referring to FIG. 1 and FIG. 7 simultaneously, first, the mobile device detects the location of the location (step S702), and obtains a first orientation of the plurality of points of interest with respect to the location of the location around the location (step S704). Thereafter, the second orientation of the plane facing the plane is detected by the mobile device, and the plane is, for example, the reverse of the screen plane of the mobile device display flag (step S706). The above steps S702 to S706 are the same as or similar to the steps S602 to S606 of the foregoing embodiment, and thus the details thereof are not described herein again.

It should be noted that, in this embodiment, after obtaining the data of the first orientation and the second orientation, the mobile device displays a road sign pole in the virtual three-dimensional space on the screen thereof, and the road sign pole represents the mobile device. The location of the location (step S708). Here, the mobile device displays the street sign bar in the virtual three-dimensional space as the positioning position of the mobile device through the point of interest flag display module 150, for example.

While displaying the street sign, the mobile device further includes the three-dimensional street sign corresponding to each point of interest extended by the street sign to point to the relative direction of the point of interest in the three-dimensional space (step S710). Further, after the mobile device indicates a road sign bar in a three-dimensional manner through the point of interest sign display module 150, the mobile device displays a three-dimensional street sign on the road sign pole based on the orientation of the inner side of the screen plane to transmit three-dimensional road signs. The street sign points to the relative direction of the point of interest relative to the inside orientation of the screen plane.

For example, Figure 8 is a schematic illustration of a street sign pole in accordance with a second embodiment of the present invention. Referring to Figure 8, the mobile device displays the street sign bar 800 in its virtual three-dimensional space displayed on its screen to represent its location. Among them, seven three-dimensional street signs 801~807 are arranged on the road sign bar 800. These three-dimensional street signs point to the direction of their corresponding points of interest, and the names and distances of the corresponding points of interest are displayed on their cards. For example, the three-dimensional street sign 804 indicates that the "MRT station" is located 150 meters to the left of the direction the user is currently facing, and so on.

It is worth mentioning that, in an embodiment, the mobile device may also be divided into multiple categories according to the nature of the point of interest or the floor on which the point of interest is located. The mobile device is, for example, selectively displaying only three-dimensional street signs of one of the classified interest points, and hiding three-dimensional street signs of other classified interest points, and the user can slide the street sign by sliding up and down to slide out the other. Part of the 3D street sign.

For example, FIG. 9A and FIG. 9B are schematic diagrams of a sliding road sign bar according to a second embodiment of the present invention. Referring to FIG. 9A, the mobile device system displays the road sign bar 800 and the three-dimensional road signs 801 to 807 as shown in FIG. 8 and hides the three-dimensional road signs of other points of interest. At this time, if the user performs a downward sliding operation on the screen in the direction of the arrow, the three-dimensional road signs 801 to 807 on the road sign bar 800 also slide down at the same time, and the three-dimensional road signs 804~807 that slide out of the screen display range are It is hidden, and the three-dimensional road signs 808~811 originally arranged on the three-dimensional road sign 801 slide down from the screen. As a result, the road sign bar 800 and the three-dimensional road signs 801~803 and 808~811 shown in Fig. 9B are presented.

In another embodiment, when the user enters the shopping center, the mobile device can classify all the stores in the shopping mall according to the floor on which they are located, and display the three-dimensional street sign of the store where the user is currently located on the street sign. And hide the 3D street signs from other store floors. In addition, the user can slide out of the store on the next floor by sliding the street sign down, or sliding the street sign down to slide out of the store on the next floor.

By means of the above-mentioned sliding road sign, it is possible to avoid the image being too cluttered due to the excessive number of three-dimensional road signs on the screen, and by hierarchically displaying the three-dimensional road signs, the user can clearly distinguish different properties or floors. Three-dimensional street sign.

In addition to the above manner of displaying other three-dimensional street signs by sliding the road sign up and down, the embodiment further provides the user to rotate the three-dimensional street sign on the road sign by rotating the road sign left and right. In detail, since the three-dimensional street sign of the embodiment is presented in a three-dimensional manner, it is possible that the card surface of the three-dimensional street sign is not facing the user because of the angle of the angle to which it is pointed, and the user cannot see the three-dimensionally. The content of the street sign. At this time, the user can turn the three-dimensional street sign on the street sign by turning the drag on the left and right, and turn the face of the three-dimensional road sign to the user. It is worth mentioning that the state of rotating the three-dimensional street sign can be, for example, after a predetermined time (for example, 3 seconds) after the user performs the touch drag and release the touch operation, or after the user touches and drags and loosens. At the time of the touch operation, it immediately returns to the opposite direction indicating the first orientation of the point of interest in the three-dimensional space with respect to the second orientation, such as the relative direction previously pointed, and provides the user with continued reference to the three-dimensional street sign to the point of interest.

For example, FIG. 10A and FIG. 10B are schematic diagrams of a rotating road sign pole according to a second embodiment of the present invention. Referring to FIG. 10A, the mobile device displays the road sign bar 800 and the three-dimensional road signs 801 to 807 as shown in FIG. 8 and hides the three-dimensional road signs of other points of interest. Among them, the content of the three-dimensional street sign 803 may be too clear because the direction of the indication is too close to the inner side of the screen plane. At this time, if the user performs a rightward sliding operation on the screen in the direction of the arrow, the three-dimensional road signs 801-807 on the road sign bar 800 also rotate counterclockwise, and the card surface of the three-dimensional road sign 803 is turned to the front.
