A navigation system may provide route guidance to a driver in order to provide routing instructions. Given that the driver may be occupied with other distractions, route guidance can be difficult for the driver to comprehend in certain scenarios. The distractions may cause a driver to miss maneuvering instructions related to the route guidance. When maneuvering instructions are missed, re-routing can lead to additional frustration, as well as a lengthier commute time. The disclosure below discusses various embodiments that may be utilized to help a driver identify the maneuvering instruction, even during a distracted situation. As discussed below, certain portions of the navigation screen that are used to aid the driver in maneuvering may flash at a predetermined rate to focus the driver's attentions on those aids. Additionally, a turn signal may be activated and flash the portions, similar to those of the navigation screen.

The display apparatus 207 may be equipped with the head-up display 209 that is disposed in the vicinity of the front of the driver seat in the vehicle 201. The display apparatus 207 may display the map or route guidance information obtained from the navigation apparatus 205 on the head-up display 209. Since the display apparatus 207 may be disposed in the vicinity of the front of a user, the display apparatus 207 may require less movement of user's visual line compared to the situation where the user looks at a display 203 included in the navigation apparatus 205 that is disposed in the center console or similar area of the vehicle cabin.
However, since the head-up display 209 is disposed in the vicinity of the front of the driver seat, the display size of the head-up display 209 must be small to not to hinder the front visual field of the user. Thus, it may be difficult to display the whole image on the head-up display 209, as opposed to the display 203 of the navigation apparatus 205. Further, since the head-up display 209 may be a transparent glass optical element, the head-up display 209 may provide a different image than that of the display 203. The display 203 may be a liquid crystal display (or similar type of display) in the navigation apparatus 205.
In one embodiment of the image display system 100, an image displayed on the display 203 of the navigation apparatus 205 may be obtained, and a part of the image may be extracted based on layout information relevant to the layout of the image. Then, by use of the extracted part of the image, an image to be displayed on the head-up display 209. The navigation image may be displayed on the head-up display 209. The navigation image may be generated from the image originally for the navigation apparatus 205 that may be one of various models, or it can be recreated.
At step 303, the system may exceed a first threshold distance that is associated with the flashing that may be associated with the maneuvering street sign image. As explained further below, another embodiment may include a second threshold distance that may be less than the first threshold distance. However, in yet another embodiment, only one threshold distance may be utilized to activate a pulsation of various portions of the navigation screen. The threshold distance may trigger activation of various portions of the navigation screen to pulsate when the distance between the vehicle and maneuvering point falls below the threshold (e.g., the vehicle is closer to approaching the maneuvering point), as explained below. For example, if the threshold distance is 100 feet, the system may begin to send instructions to pulsate various portions of the navigation screen when the vehicle is 99 feet away from the maneuvering point. However, if the vehicle does not fall below the threshold distance (e.g., above 100 feet), the system may continue to monitor the distance at which the vehicle is approaching a maneuver during route guidance mode.
At step 305, the system may cause a pulsation of certain areas of the navigation screen at a first rate. The pulsation may be associated with the maneuvering image and street sign image. The maneuvering image and street sign image may be programmed to flash at a predetermined rate (e.g., the first rate) upon approaching the upcoming maneuver. The maneuvering image may be associated with a turn arrow that is associated with the upcoming maneuver during route guidance. In another embodiment, the street image (e.g., street geometry) may also flash at a predetermine rate upon approaching the maneuver. The flashing may be a portion of the route guidance that is overlaid on the street associated with the maneuver. In yet another embodiment, both the street image and the maneuvering action may pulsate in coordination, or in an out-of-sync fashion.
At step 307, the system may fall below a second threshold distance between the vehicle to the maneuver point. The second threshold distance may be associated with causing the maneuvering street sign image to flash or pulsate. The second threshold distance may cause activation of various portions of the navigation screen to pulsate when the distance between the vehicle and maneuvering point falls below the second threshold. The second threshold distance may be less than the first threshold distance. Thus, the system may speed up the pulsation of the maneuvering action and/or street sign image. For example, if the second threshold distance is 25 feet, the system may send instructions for various portions of the navigation screen to pulsate when the vehicle is 24 feet away from the maneuvering point. However, if the vehicle does not fall below the second threshold distance (e.g., above 25 feet), the system may continue to monitor the distance at which the vehicle is approaching a maneuver during route guidance mode. The predetermine rate at which the various portions flash may increase after the vehicle falls below the second threshold distance until the maneuver (e.g., the vehicle is closer to the maneuver point). While the system discloses two different thresholds to change the pulsation rate, any number of thresholds may be utilized that causes changes to the pulsation rate. Furthermore, the pulsation rate may also coordinate directly with the distance to the maneuvering point upon passing a first threshold (or any other threshold).
In another embodiment, the pulsation may occur when a user activates a turn signal during route guidance. Thus, the turn signal may eliminate the need for either a first or second threshold in one embodiment or may be utilized in addition to the thresholds. For example, the driver or occupant may activate a turn signal to output a left turn or right turn to the associated lights of the vehicle. The interface may allow the pulsation to have the same rate as the rate of the turn signal lights. Furthermore, the pulsation may be coordinated with the turn signal light to “flicker” at the same time or same rate as the portions of the navigation screen.
The interface screen 400 may also include a maneuvering image portion 403. The maneuvering image portion 403 may indicate a graphical image associated with the upcoming maneuver that is required to keep the vehicle on route guidance. As shown in
The interface screen 400 may also include a maneuvering street sign image portion 405. The maneuvering street sign image portion 405 may indicate a graphical image associated with the street (e.g., or road geometry) for upcoming maneuver that is required to keep the vehicle on route guidance. As shown in
The interface screen 400 may also include a route guidance portion 407 that may be highlighted. The route guidance highlighted portion 407 may be overlaid onto the road geometry to display to a driver the route information to the destination. Thus, the route guidance highlighted portion 407 may be highlighted if the user is going to maneuver on a portion of the map, as opposed to an unhighlighted portion of the map (e.g., road geometry) that is not affiliated with the route. In another embodiment, the pulsation may also occur at the route guidance highlighted portion 407. The interface screen may also include a graphical image associated with a current vehicle position (“CVP”), sometimes called a CVP icon 409. The CVP icon 409 may display the vehicle's location relevant to the map data. The CVP icon 409 may be an arrow or any other graphical image utilized to represent the vehicle.
The interface screen 450 may also include a maneuvering image portion 404. The maneuvering image portion 404 may indicate a graphical image associated with the upcoming maneuver that is required to keep the vehicle on route guidance. As shown in
The interface screen 450 may also include a maneuvering street sign image portion 406. The maneuvering street sign image portion 406 may indicate a graphical image associated with the street (e.g., or road geometry) for upcoming maneuver that is required to keep the vehicle on route guidance. As shown in
The interface screen 450 may also include a route guidance highlighted portion 407. The route guidance highlighted portion 407 may be overlaid onto the road geometry to display to a driver the route information to the destination. Thus, the route guidance highlighted portion 407 may be highlighted if the user is going to maneuver on a portion of the map, as opposed to an unhighlighted portion of the map (e.g., road geometry) that is not affiliated with the route. In another embodiment, the pulsation may also occur at the route guidance highlighted portion 407. The interface screen may also include a graphical image associated with a current vehicle position (“CVP”), sometimes called a CVP icon 409. The CVP icon 409 may display the vehicle's location relevant to the map data. The CVP icon 409 may be an arrow or any other graphical image utilized to represent the vehicle.
