AI Technical Summary

Benefits of technology

This patent is about a system and method for improving navigation instructions. It can compute new navigation instructions based on previous ones or a previously traveled route. It can also analyze the new instructions and generate notifications if there are any differences. These notifications can be provided based on the locations. The technical effect of this patent is to provide more accurate and efficient navigation instructions.

Problems solved by technology

The effectiveness of these laws alone, without an effective means of enforcement, is questionable.
Being that cellular phones are generally small and discreet and drivers are frequently in motion, it is often difficult for law enforcement personnel to effectively police for such violations.
Indeed, statistics show that crashes arising from cellular phone-based distractions are increasing as the popularity of such devices increases.
Given the easy accessibility of cell phones to drivers, many drivers' apparent desire to operate their cellular phones while driving, and the difficulties attendant with enforcing laws prohibiting cellular phone use, it is likely that drivers will continue to use cellular phones for texting, talking, and / or other activities (e.g., playing games or running applications), for the foreseeable future.
Moreover, it can be appreciated that the usage of mobile devices in various locations and / or settings can be detrimental on a number of levels.
Additionally, many students have become adept at using such devices discreetly, resulting in many instances of cheating being facilitated through the use of mobile devices.

example 1

[0460]There are a number of inputs that can be utilized in various arrangements in order to identify one or more user determination characteristics, such as the location of a mobile device 105 and / or if a mobile device 105 is being operated by the driver or by the passenger of a car / truck / bus, such as:

[0461]As also noted above, various arrangements preferably incorporate identification of one or more of the user determination characteristics referenced above and herein. In certain arrangements, each user determination characteristic (e.g. error proportion, correlation of typing speed to acceleration etc.) can be considered as a point in a K-dimensional space. Classification algorithms based on supervised learning, as are well known to those of ordinary skill in the art, can then be applied to the resulting K-dimensional signature(s) to determine the probability that the in-vehicle role of the user of mobile device 105 is a driver or a passenger.

example 2

[0528]As noted above, such as at steps 222 and 223, considering multiple inputs can increase the accuracy of one or more of the determinations described herein, such as the determination of an in-vehicle role of a user of a mobile device 105, 160. This advantage is further illustrated above at steps 225 and 226, wherein inputs from multiple devices are considered in order to compute such determinations. Further illustrations of such inputs / determinations include, but are not limited to:

[0529]In-Vehicle Location—In the United States and in most other countries in the world, drivers are the left-front most occupant in a vehicle, relative to the front end of the vehicle. By identifying whether a particular mobile device 105, 160 is or is not the left-front most device within a vehicle, a determination can be made that such device 105, 160 is or is not being operated by the driver.

[0530]It should be understood that the referenced in-vehicle identification / determination is preferably ach...

example 3

[0534]As noted above, the processing of the various inputs discussed herein is preferably enhanced by incorporating various additional processing operations which serve to further enhance the accuracy of the determinations that are made. Examples of such further processing operations include, but are not limited to:

[0535]Clock synchronization—As noted above, in arrangements where inputs originating from multiple devices 105, 160 are processed together (such as several of those referenced above in EXAMPLE 2), it is preferable that simultaneous timing measurements originating at the respective devices 105, 160 are compared as well. In one arrangement, this can be effectively achieved by synchronizing the internal clocks of the respective devices 105, 160. By way of illustration, a relative displacement can be estimated, and this estimate can be used to process all relevant inputs such that they are synchronized to the same clock.

[0536]Examples of such synchronization methods include: ...

Abstract

Systems and methods are provided for improved navigation instructions. In one implementation instructions between two locations can be computed, the instructions can be processed in relation to previously computed instructions between the same locations and / or a previously traveled route between the same locations to determine disparitie(s) therebetween, and a notification can be generated based on the disparitie(s). In another implementation, one set of instructions between two locations can be received, another set of instructions between two other locations can be received, the sets of instructions can be processed to determine disparities between them with respect to one or more locations, a notification can be generated based on the one or more disparities, and the notification can be provided in relation to the location(s).
