• a system in which the present concepts can be implemented need to necessarily involve a tracking device or a driver device traveling to a destination or to a customer device but can simply be a server such as server 112 tracking a moving object such as tracking device 104, driver device 208, etc.
• server 112 is tasked with tracking a moving object associated with user 102.
• Information regarding a tracked object may be utilized for various purposes including, but not limited to, content conversion tracking, providing arrival alerts to an intended destination for an impending arrival of the moving object at the intended destination (e.g., in order to provide an alert to destination 106 at a threshold time ahead of user 102’ s arrival at destination 106, so that operator 108 at destination 106 can prepare and ready order(s) for user 102 to pick up when he or she arrives at destination 106), etc.

• Various statistic data can include, but is not limited to, past completed trips of users to destination 106, past completed trips of user 102, traffic conditions, modes of transportation, types of moving objects associated with user 102 (and/or driver 206 in FIG. 2), weather conditions, times of days, events taking place en route to destination 106 or at destination 106, speed of the moving object, any construction, road closures and improvement, historical stops made by user 102 on such route and/or purchases made en route, etc.
• the statistical data can be stored in database 118.

Accordingly, in determining location information of user 102 as user 102 travels to the downtown location of the brick-and-mortar store and depending on the time of day, server 112 can augment its prediction and improve the determination of location information of user 102 using the corresponding destination specific model and/or other historical data in database 118 corresponding to visits/stops of user 102 en route. For example, user 102 may typically stop at a particular gas station or a particular convenient store whenever user 102 visits the brick-and-mortar store. Such information is also taken into consideration by server 112 in determining location information of user 102.
• FIG. 3 illustrates an example method of creating destination specific models, in accordance with one aspect of the present disclosure.
• FIG. 3 will be described with reference to FIG. 1. However, the concepts described are equally applicable to the system of FIG. 2 as well.
• the method illustrated in FIG. 3 begins after one or more notifications have been provided to destination computing device 110 regarding an arrival prediction of user 102 at destination 106 to pick up order(s) (or one or more trips to destination 106 have been completed).
• Server 112 can store a collection of data in database 118.
• the data can be any one or more of statistical data examples provided above.
• server 112 can store information regarding the quality of past notifications and an identifier of the past notifications.
• server 112 every time server 112 has provided an arrival alert to destination 106 indicating that user 102 will arrive in 8 minutes, server 112 compares this estimated arrival time to an actual time it took user 102 to arrive at destination 106. For example, while server 112 predicted, at time TO, that user 102 will arrive at destination 106 in 8 minutes, in reality, it may take user 102 6 minutes from TO to arrive at destination 106. This indicates a prediction error of 25%. Server 112 stores this prediction error in database 118. During the next round of prediction and in providing the arrival alert, server 112 adjusts its prediction by 25% before providing the arrival alert (e.g., in the particular example described above, instead of providing the arrival alert at TO, server 112 now provides the arrival alert at Tl which is 2 minutes earlier than TO).
• server 112 adjusts its prediction by 25% before providing the arrival alert (e.g., in the particular example described above, instead of providing the arrival alert at TO, server 112 now provides the arrival alert at Tl which is 2 minutes earlier than TO).
• server 112 queries computing device 110 of destination 106 for rating a quality of a recently provided arrival alert. Operator 108 operating destination computing device 110 can respond to the query. Upon receiving the response, server 112 stores the rating at S306. In addition to, simultaneous with or instead of querying computing device 110 for rating, at S304, server 112 can calculate a rating or prediction error regarding the arrival alert, as described above. Similarly, the calculated rating is received at S306.
• server 112 can record the received rating(s), per S302 and S304, in database 118 in association with an identification (ID) of the notification.
• ID can be an identification of a particular transaction between user 102 and a merchant at destination 106, can be an identification associated with user 102, can be an identification associated with destination 106 or any combination thereof.
• Server 112 can also store in database 118, information regarding a route taken by user 102 in connection with a recently completed trip to destination 106, and any other data pertinent to the trip that resulted in the notification.
• the route taken by user 102 can be learned from data reported by location service 105 to server 112 while user 102 and associated computing device 104 were traveling to destination 106. In some examples, from this route information, server 112 can determine if user 102 made any stops while in route to destination 106.
• Server 112 can also record a time of day, day of week, and date associated with the notification in database 118. Server 112 can aggregate the above data for trips by many users.
• server 112 applies machine learning algorithm(s) to the historical data specific to destination 106 stored in database 118.
• server 112 generates destination specific model for destination 106 based on the machine learning algorithm(s) applied to stored data at S310.
• destination specific model may be created or trained by analyzing factors associated with notifications that were considered of good quality and factors associated with notifications that were considered of poor quality. Since the destination specific model is generated through machine learning, some dimensions of destination specific model may not have any semantic meaning while some dimensions may have a semantic significance. For example, those dimensions having a semantic meaning can include likelihood that a user will make other stops along the route, likelihood that a user will encounter traffic along the route, the most likely routes to the destination, etc.
• machine learning may initially be trained on all data in database 118 regardless of destination to result in a location non-specific model.
• destination specific model may be the result of tuning the location non-specific model for factors relevant to the specific destination 106.
• server 112 relies on location updates received from tracking device 104 in order to determine current location of user 102.
• the location updates received from tracking device 104 can be GPS signals (satellite signals) readings obtained by a GPS backing device embedded in tracking device 104.
• Server 112 by relying on data obtained from external sources such as a public database, may have a record of precise geographical coordinates of any given geographical location (latitude and longitude values). Such precise geographical coordinates may be referred to as registered geographical coordinates or simply registered coordinates of a given geographical location. Therefore, every time server 112 receives a GPS signal reading from tracking devices, server 112 can compare the GPS reading received, which includes latitude and longitude values of the corresponding geographical location, with the registered geographical coordinates of the same location.
• the server 112 would then consider the received coordinates as“precise”.
• a threshold e.g., less than 5 meters, 10 meters, within a margin of error of less than 5%, 10%, etc.
• server 112 can build up a database of geographical areas in which average error of received GPS signals readings from backing devices are not “precise”. These geographical areas may be stored at server 112 and may be referred to as high error zones. Thereafter, whenever a tracking device is located within a high error zone, and as will be discussed below, any sparse“precise” GPS readings received from said tracking device may be used as a reference point after which determination of movement and hence the location of the tracking device may be augmented using on-board sensors and displacement/location calculations (information) of the tracking device. This can improve the location updates of the tracking device received at the server 112.
• GPS signal readings While using on-board sensor data can accommodate for inaccuracies in GPS signal readings when tracking device 104 is located in a high error zone, even when such GPS signal readings are“precise,” reliance on GPS signal readings alone may be insufficient to track and record relatively small movements of tracking device 104. For example, GPS signal readings may be insufficient to differentiate between a tracking device’s presence in two adjacent stores or two stores located on top of each other on different levels of a mall, etc.
• This deficiency can translate into missing user l02’s presence in one store (for which an advertisement was pushed/provided to tracking device 104) and inadvertently determining user l02’s presence in an adjacent store (for which no advertisement was pushed/provided to tracking device 104), which can in turn result in inaccurate determination of content conversion rates for the advertisement pushed/provided to tracking device 104.
• Augmenting GPS signal readings with data from on-board sensors of a tracking device not only provides the above described advantage, it can also be used to send more targeted content to the tracking device as will be described below.
• FIG. 4 illustrates an example method of location determination using on-board sensor- data, in accordance with one aspect of the present disclosure.
• FIG. 4 will be described from the perspective of server 112 and with reference to FIGs. 1-3.
• processors such as processor 114 of server 112 executes computer readable instructions stored on or more memories such as memory 116 to implement the functionalities described below.
• server 112 detects that tracking device 104 is in a high error zone. In one example, server 112 detects the presence of tracking device 104 in the high error zone based determining that the latest location update (or average of a predetermined number of location updates recently received from tracking device 104) corresponds to one or more geographical areas identified as high error zones by server 112, as described above.
• server 112 receives a location update (e.g., a GPS signal reading) from tracking device 104 that may be indicative of a current location (geographical coordinates) of tracking device 104.
• a location update e.g., a GPS signal reading
• server 112 determines if the location update (GPS signal) received from tracking device 104 at S402, after detecting the presence of the tracking device 104 in the high error zone, is accurate (“precise”). In one example, this accuracy determination is based on comparing the coordinates of a current location of the tracking device indicated in the received location update to registered coordinates of the same location at server 112.
• server 112 determines that the location update is accurate.
• server 112 determines that the recently received location update is accurate, at S406, server 112 updates its record of current location of tracking device 104 using the received current location and registers (stores) the current location as the“latest precise location” or the“latest reference point”. Thereafter, the process proceeds to S408, which will be described below.
• server 112 determines that the received location update is not accurate, then server 112 simply uses the last received accurate or precise location update as the“latest reference point.”
• server 112 sends commands to tracking device 104 to turn on (activate) its on-board sensors to be used for tracking movement of the tracking device 104.
• on-board sensors include, but are not limited to, gyroscope, accelerometer, magnetometer, etc.
• tracking device 104 enables said sensors and can collect movement and location data to perform calculations on-board in order to determine the amount of displacement of tracking device 104 since activation of the sensors. These calculations can be done according to any known or to be developed method.
• server 112 At S410 and at the time of providing next location update by tracking device 104, server 112 also receives the calculations performed on board tracking device 104 (may be referred to as displacement information)
• server 112 retrieves the “latest reference point” (e.g., stored at S406 described above) and updates the same with the displacement information received at S410.
• server 112 uses the location update of S402 instead of the“latest reference point of S406 and updates the location update from S402 with the displacement information received at S410.
• the updating may also be based on the destination specific model for destination 106 that sever 112 may have generated for destination 106 per the process of FIG. 3.
• the specific destination model for destination 106 may include information on correlation between traffic (e.g., average speed and time) on a current route of which user 102 and tracking device 104 are travelling to destination 106 and time of day. Therefore, if a particular time period (e.g., afternoon rush hour between 4PM to 6PM) is associated with a 10% slower traffic on the current route and the current time (as the user 102 is traveling to destination 106) falls within such time period, then server 112 may update the“latest reference point” with the displacement information and/or an additional factor of 10% due to the relatively slower traffic.
• a particular time period e.g., afternoon rush hour between 4PM to 6PM
• server 112 may update the“latest reference point” with the displacement information and/or an additional factor of 10% due to the relatively slower traffic.
• a high error zone may not necessarily be in a downtown area or an area with structures that block GPS signals. Instead a high error zone may be a geographical area (may be an open field or a remote region), where signal reception and strength of GPS signals are weak or less than a threshold amount of strength. Accordingly, the process of FIG. 4 is equally applicable to such remote or open field example of a high error zone.
• server 112 can act as a content provider, where examples of contents include, but are not limited to, advertisements, coupons, promotions etc. Additionally, server 112 can act as an intermediary for providing (pushing) content provided by third party platform 122 to tracking device 104.
• content providing systems target users with advertisements or coupons based on an estimated geographical location of a tracking device. For example, when a user is detected to be present in a mall, existing content providers provide the user with advertisements, coupons, promotions, etc. for all merchants operating in the shopping mall, regardless of the exact location of the user. Location determination based on on-board sensor data can improve the accuracy of a user’s determined location and thus help provide more targeted advertisements to the user.
• FIG. 5 is an example method of content providing based on location determination using on-board sensor data, in accordance with an aspect of the present disclosure.
• FIG. 5 will be described from the perspective of server 112 and with reference to FIGs. 1-4.

• server 112 receives a call from user 102 via tracking device 104.
• the call may be the same as a location update provided by the tracking device 104 to the server 112, as described above.
• server 112 determines a tile (geographical tile) associated with the location update of tracking device 104 received at S500 and provides the same to the tracking device 104.
• a tile identifies coordinates/boundaries of a geographical location.
• Server 112 may have a database of tiles stored thereon.
• a tile can identify a specific geographical area. For example, server 112 can divide a city or a downtown area into several tiles/sections (e.g., square tiles, polygon tiles, etc.) spanning the entire city or downtown area.
• Server 112 determines (selects) the tile to be provided to tracking device 104 based on the location update received from tracking device 104 as part of the call at S500.
• a tile can include polygons of user l02’s interests. For example, such polygons include a foot print of a particular store, foot prints of locations that offer a particular type of product or services of interest to user 102, etc. Polygons of interest can also be referred to as zones of interest.
• server 112 performs the process of FIG. 4 to determine a location of tracking device 104 within the tile assigned to tracking device at S502, based on GPS signals and on board sensors of tracking device 104. More specifically and per FIG. 4, the location of tracking device 104 within the tile assigned thereto at S502 is determined based on received GPS signal readings from tracking device 104 and on-board sensors of tracking device 104 turned on for data collection and on-board movement/displacement determination ⁇ Accordingly, at S504, server 112 determines an exact location of tracking device 104 within the tile assigned to tracking device 104 at S502 by augmenting the GPS signals with displacement information determined using on-board sensors of tracking device 104.
• server 112 determines whether tracking device 104 and user 102 are detected to be within a particular polygon or zone of interest. This can be done by comparing location coordinates of tracking device 104 based on the location determined at S504 and determining if the coordinates fall within (and/or on or within a threshold percentage) of perimeters or boundary of the tile of S502.
• a polygon of interest can be, but is not limited to, a particular store location, a restaurant, any type of business location, a museum, a point of interest, etc.
• server 112 determines that the tracking device 104 is not in a polygon of interest associated with the tile, the process reverts back to S506 and server 112 repeats S504 and S506 until tracking device 104 is detected in a polygon of interest.
• server 112 can perform a series of content (or at least one content) pushes to tracking device 104 and/or another electronic device associated with user 102 that is capable of receiving notifications, pushes containing contents, etc.
• the content pushed to tracking device 104 includes specific promotions and coupons associated with the polygon of interest.

• the content pushed can be a specific action to be taken by user 102 within the polygon of interest such as making payment for an order, scheduling next appointment, completing paperwork, etc.
• zone/polygon specific content can be provided to tracking device 104 at S502. Accordingly, tracking device 104 and server 112 need not communicate when tracking device 104 is detected within a polygon of interest. In other words, example contents to be provided to tracking device 104 at S508 can instead be provided to tracking device 104 at S502. Therefore, user 102, through tracking device 104, can automatically get a notification of content, take a particular action such as making an automatic payment, as soon as tracking device 104 is within a particular polygon of interest, without having the content, payment reminders, etc., be pushed to tracking device 104 after tracking device 104 is detected within the corresponding polygon of interest.
