Embodiment Construction

[0012] In some embodiments described herein, navigation software can continuously generate a route to a moving object in real-time. For example, a target mobile device may automatically monitor its own location and issue location information updates in real-time when its location has changed by more than a threshold amount. Mapping software (located on a source device such as a mobile phone or a server computer) can receive real-time updates from the target device and generate new route directions from the source device to the target device. The target mobile device may include an option to send its Global Positioning System (GPS) coordinates or other position / location information directly to the server computer or source device. The direct peer option, which sends directly to the source device, prevents third-party services from tracking the target device for security reasons. A server-based sharing option may allow multiple source devices to more efficiently track a target'...

Abstract

A source device can navigate towards a moving destination target device, such as when two mobile phones are moving towards each other. The source device can receive an initial position of the target and a route to the target. As the source device and target device simultaneously move, the route can be updated. For example, if a distance of movement exceeds a threshold (e.g., 1 mile) the route can be updated. In another embodiment, a target device can switch between position tracking devices so as to provide less accurate position information, but save power, or provide high accuracy position information at the cost of higher power consumption. Generally, the switching between position tracking devices and the frequency at which the route to the destination point can be based on the distance apart between the source device and target device.

Description

Background technique [0001] The incorporation of location and navigation technologies, such as Global Positioning System (GPS) technology, into mobile phones and similar wireless portable devices has created a class of "location-aware" devices that allow users to communicate with other users as well as determine or Even see where other users are. Such devices may be configured to display area maps and locations of other users and / or points of interest on their devices. However, techniques have generally been limited to navigating to fixed locations. Little has been done to address navigation to another client device that itself is moving. Contents of the invention [0002] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of ...
