Problems solved by technology

Some turns are easy to execute in some situations, but more difficult in others, such as heavy traffic or rain
Current personal navigation devices do not have the ability to consider any of these contextual factors when prompting the user for an upcoming turn

Embodiment Construction

[0013] Various aspects will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the invention or the claims.

[0014] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0015] As used herein, the term "personal navigation device" refers to a variety of computer devices that can be configured with a navigation system capable of providing turn-by-turn turn-by-turn directions, including but not limited to global positioning system (GPS) receivers, vehicles (e.g., GPS receivers in automobiles), cellular phones, smart phones, pers...

Abstract

Embodiment methods and systems enable personal navigation devices to warn drivers during turn-by-turn navigation directions when they are approaching a difficult turn. Personal navigation devices may report to a server when a turn is missed during turn-by-turn directions, including identifying the turn and situation information. The server may aggregate missed turn reports from many personal navigation devices to generate a difficult turn database. Personal navigation devices may access the difficult turn database when generating turn-by-turn directions to identify turns requiring enhanced directions. The difficult turn database may be stored on personal navigation devices, and/or may be maintained on the server. Personal navigation devices may be configured to recognize when turns are intentionally missed, and only report missed turns when they determined that the turn was missed unintentionally. Indications of turn difficulty may be correlated to situation information received in missed turn reports to more accurately reflect when turns are difficult.

Description

Background technique [0001] Personal navigation devices, such as global positioning systems, in use today provide turn-by-turn directions from the device's current location to a destination selected and entered by the user. While some personal navigation devices allow the user to determine the level of prompts provided by the device, most devices do not allow such customization and always provide the same level of prompts for each turn along a specified route. Even devices that allow the user to select a desired level of prompting provide the selected level of prompting for all turns and do not have the ability to change the level of prompting provided without further user input. [0002] A problem with the current state of the art is that not all turns along a given route require the same level of cues from the personal navigation device. Some turns are simply easier to execute than others. Some turns are easy to execute in certain situations, but more difficult to execute ...
