Proactive Recording of Locations for Backtracking - A simplified explanation of the abstract
This abstract first appeared for US patent application 18299011 titled 'Proactive Recording of Locations for Backtracking
Simplified Explanation
- This patent application describes methods, mediums, and systems for providing historical positioning information. - The device is able to detect certain conditions in user contextual data that trigger the collection of a set of historical positions within a specific time frame called a lookback window. - The device then receives at least one historical position from the set of historical positions within the lookback window. - The received historical position is classified by the device based on one or more features to determine if it can be considered as a candidate location for a backtrack route. - Based on this classification, the device decides whether to provide the historical position as part of the lookback window. - The purpose of this innovation is to provide accurate historical positioning information to assist users in retracing their steps or navigating back to a specific location.
Original Abstract Submitted
Methods, non-transitory machine-readable mediums, and system to provide historical positioning information are described. In an embodiment, a device detects one or more conditions in user contextual data that trigger collection of a set of historical positions for a lookback window, the device receives at least one historical position from the set of historical positions for the lookback window, the device classifies the at least one historical position based on one or more features as a candidate location for a backtrack route, and the device determines to provide the at least one historical position as part of the lookback window based on the classification.
