## Background
GOVERNMENT RIGHTS
This invention was not made with United States Government support. The United States Government does not have certain rights in this invention.
TECHNICAL FIELD
The present disclosure relates to a system and method for map collaboration.
BACKGROUND
In many kinds of planning situations, multiple users need to remotely collaborate on a shared map. If the shared map is large enough, each user may have no idea what portions of the map the other users are currently viewing. The users may also have no way to quickly move to the locations other users are viewing. Current map collaboration systems display only the current location of each user, and permit only a single (i.e., either a two dimensional or a three dimensional) map environment.

DETAILED DESCRIPTION
The following description and drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.
In an embodiment of a map collaboration system, each user is provided with a customizable icon. The icon for each user is placed on the map at the location that he or she is currently viewing (or that is being displayed on a device that is associated with that user). In three dimensional map environments, the icon is also placed at the altitude of the user. This allows every user to be aware of what segments of the map that other users have displayed on their devices. A user can click on an icon, and jump to the portion of the map that is displayed on the device associated with the selected user icon. A user can also click on a user in a list of users and immediately jump to the portion of the map that is currently displayed on the selected user's device.
An embodiment can also display on the map a graphic that represents the portion of the map that is displayed to each user. As illustrated in FIG. 2, in two dimensional map environments, the graphic can be a polygon surrounding each user icon. As illustrated in FIG. 3, in three dimensional map environments, the graphic can be a pyramid that intersects with the earth, and that represents the volume of space that is displayed on the device of a user. These visualizations allow users to easily determine the areas of the world that are in each user's view range.
Additionally, an embodiment displays the real-time location of all users and also highlights the portion of the map that is currently displayed on a device associated with each user. An embodiment further allows some users to use two dimensional maps and at the same time or during the same session others to use three dimensional maps, with the two dimensional and three dimensional visualizations functioning in one or more map environments.
Consequently, one or more embodiments address the following issues with current map collaboration systems. First, an embodiment permits remotely located users to collaborate on a shared map in real time. Second, on large maps, an embodiment permits users to be aware of what portion of the map other users are viewing (or at least the portion of the map that is displayed on another user's device). Third, an embodiment permits a user to quickly jump to other users' locations. While prior map systems have attempted to provide these capabilities, such as by syncing the position of a map between two or more users, and/or collaboratively editing the map, such prior systems provide no visual representation of where all active users are located.
In an embodiment, each user has a customizable icon, and the icon for each user is placed at the location that is displayed on a device associated with that particular user. Users can click on the user name of other users to jump to the location of the other users (that is, display what is displayed to the other users). Such a display includes a visual representation of the area each user can see, and the area is displayed around each user's icon. As noted, users can instantly jump to the location of other users, can see the real-time location of other users, and can see what areas of the map are being displayed to other users. As noted, an embodiment can handle the differences between different types of maps during a collaboration session, that is, between two dimensional and three dimensional maps.
FIGS. 4 and 5 are block diagrams illustrating steps and features of two example embodiments of map collaboration processes and systems. FIGS. 4 and 5 include a number of process blocks 405-476 and 505-566 respectively. Though arranged serially in the examples of FIGS. 4 and 5, other examples may reorder the blocks, omit one or more blocks, and/or execute two or more blocks in parallel using multiple processors or a single processor organized as two or more virtual machines or sub-processors. Moreover, still other examples can implement the blocks as one or more specific interconnected hardware or integrated circuit modules with related control and data signals communicated between and through the modules. Thus, any process flow is applicable to software, firmware, hardware, and hybrid implementations.
At 405, a map of a geographic area is displayed on a device associated with a first user, and at 410, an icon is displayed on the device associated with the first user. The icon represents a second user. At 415, an indication is displayed on the device associated with the first user. The indication represents an area of the map displayed on a device associated with the second user.
At 420, input is received from the first user that selects the icon representing the second user. At 422, the map of the geographic area that is displayed on the device associated with the second user is displayed on the device that is associated with the first user. At 424, the entire map of the geographic area that is displayed on the device associated with the second user is displayed in full screen mode on the device associated with the first user. That is, the geographic area that is displayed on the device associated with the second user can be displayed on the device associated with the first user as either a thumbnail, as the entire display, or some intermediate sized display.
In an embodiment, the display of the indication on the device associated with the first user that represents the area of the map displayed on the device associated with the second user addresses situations wherein the first user and second user have different display capabilities. For example, at 430, in response to a display of a three-dimensional map on the device of the second user, the indication on the device of the first user is displayed as a three dimensional object or form on a two dimensional display of the device of the first user. As another example, at 432, in response to a two-dimensional map that is displayed on the device of the second user, the indication on the device of the first user is displayed as a two dimensional plane that intersects a three dimensional display of the device of the first user. In another embodiment, two dimensional maps can be displayed with different projections. That is, an embodiment can translate a view visualization from one two dimensional projection to another two dimensional projection.
At 440, the display of the map on the device associated with the first user, the display of the icon representing the second user on the device associated with the first user, and the display of the indication on the device associated with the first user, occur in real time or near real time. At 445, the display of the map of the geographic area on the device associated with the first user includes a display of the entire geographic map and a display of an icon for each user whose device has displayed thereon at least a portion of the geographic map. This feature provides a landscape of the location of all the users who are using the map collaboration system. At 450, it is noted that the device associated with the first user is a mobile communications device. The devices associated with the other users can also be mobile communication devices. Also, one or more users can use a lap top computer or other less mobile device, especially in instances wherein the user has managerial, operator, or commander types of responsibilities.
At 455, the display of the indication includes a three dimensional display of the indication. At 457, the display of the indication includes one or more of a location, an area, and an altitude.
At 460, a user's own icon is displayed on the device that the user is using. In embodiments in which the user is displaying the icons of other users, the display of the user's own icon provides information to the user about the relative location of other users.
An embodiment that uses a location manager server is illustrated in FIG. 1. Referring to FIGS. 1 and 4, at 110 and 470, input is received from a user A. At 472, the geographic area of the map displayed on the device associated with user A is modified based on the input received from user A. At 120 and 474, the modified geographic area of the map displayed on the device associated with user A is transmitted to the location manager. Then, at 476, the devices 130 associated with users B, C, and D are modified such that the indication representing the area of the map displayed on the device associated with user A is now displayed in part or in whole on the devices 130 associated with users B, C, and D.
FIG. 5 illustrates another embodiment of a map collaboration process and system. At 505, a map of a geographic area is displayed on a device that is associated with a first user. At 510, a list of users is displayed on the device associated with the first user. The users on the list have communication devices that are associated with them. The communication devices associated with the users on the list are configured to display at least a portion of the map of the geographic area. At 515, input is received from the first user. The input received from the first user includes a selection of a user from the list. At 520, the portion of the map of the geographic area that is displayed on the device associated with the user selected from the list is displayed on the device that is associated with the first user.
At 525, an icon representing the user selected from the list is displayed on the device associated with the first user. At 527, the entire map of the geographic area that is displayed on the device associated with the user selected from the list is displayed on the device that is associated with the first user. That is, with this feature, the entire map of the geographic area can be displayed on only a portion of the display of the device that is associated with the first user (e.g., as a thumbnail). At 529, the entire map of the geographic area that is displayed on the device associated with the user selected from the list is displayed in full screen mode on the device associated with the first user. That is, with this feature, the entire map of the geographic area is displayed on the entire area of the display of the device that is associated with the first user.
At 530, the display of the portion of the map of the geographic area that is displayed on the device associated with the user selected from the list includes a three dimensional display. At 532, the three dimensional display includes one or more of a location, an area, and an altitude.
At 540, the display of the map on the device associated with the first user, the display of the icon representing the user selected from the list on the device associated with the first user, and the display of the portion of the map of the geographic area that is displayed on the device associated with the user selected from the list on the device associated with the first user, occur in real time or near real time. At 545, the display of the map of the geographic area on the device associated with the first user comprises a display of the entire geographic map and a display of an icon for each user whose device has displayed thereon at least a portion of the geographic map. As noted above in connection with FIG. 4, this feature permits a user to observe his or her location relative to the locations of others. At 550, it is noted that the device associated with the first user is a mobile communications device. At 555, an icon is displayed on the geographic map representing the first user. This feature, just like the previously discussed feature, permits a user to examine his or her location as it pertains to others.
At 560, input is received from the user selected from the list. At 562, the geographic area of the map displayed on the device associated with the user selected from the list is modified based on the input received from the user selected from the list (FIG. 1, No. 110). At 564, the modified geographic area of the map displayed on the device associated with the user selected from the list is transmitted to one or more of a location manager (FIG. 1, No. 120) or the device associated with the first user. At 566, the display of the device of the first user is modified with the new portion of the map of the geographic area that is displayed on the device associated with the user selected from the list (FIG. 1, No. 130).
