Definitions
- the present invention relates to a navigation apparatus of the type that displays navigation information to a user.
- the present invention also relates to a method of displaying information to a user of a navigation apparatus.
- Portable computing devices for example Portable Navigation Devices (PNDs) that include GPS (Global Positioning System) signal reception and processing functionality are well known and are widely employed as in-car or other vehicle navigation systems.
- GPS Global Positioning System
- a modern PND comprises a processor, memory (at least one of volatile and non-volatile, and commonly both), and map data stored within said memory.
- the processor and memory cooperate to provide an execution environment in which a software operating system may be established, and additionally it is commonplace for one or more additional software programs to be provided to enable the functionality of the PND to be controlled, and to provide various other functions.
- these devices further comprise one or more input interfaces that allow a user to interact with and control the device, and one or more output interfaces by means of which information may be relayed to the user.
- output interfaces include a visual display and a speaker for audible output.
- input interfaces include one or more physical buttons to control on/off operation or other features of the device (which buttons need not necessarily be on the device itself but could be on a steering wheel if the device is built into a vehicle), and a microphone for detecting user speech.
- the output interface display may be configured as a touch sensitive display (by means of a touch sensitive overlay or otherwise) additionally to provide an input interface by means of which a user can operate the device by touch.
- Devices of this type will also often include one or more physical connector interfaces by means of which power and optionally data signals can be transmitted to and received from the device, and optionally one or more wireless transmitters/receivers to allow communication over cellular telecommunications and other signal and data networks, for example Bluetooth, Wi-Fi, Wi-Max, GSM, UMTS and the like.
- PNDs of this type also include a GPS antenna by means of which satellite- broadcast signals, including location data, can be received and subsequently processed to determine a current location of the device.
- the PND may also include electronic gyroscopes and accelerometers which produce signals that can be processed to determine the current angular and linear acceleration, and in turn, and in conjunction with location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- electronic gyroscopes and accelerometers which produce signals that can be processed to determine the current angular and linear acceleration, and in turn, and in conjunction with location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- PNDs The utility of such PNDs is manifested primarily in their ability to determine a route between a first location (typically a start or current location) and a second location (typically a destination). These locations can be input by a user of the device, by any of a wide variety of different methods, for example by postcode, street name and house number, previously stored "well known” destinations (such as famous locations, municipal locations (such as sports grounds or swimming baths) or other points of interest), and favourite or recently visited destinations.
- the PND is enabled by software for computing a "best” or "optimum” route between the start and destination address locations from the map data. A “best" or “optimum” route is determined on the basis of predetermined criteria and need not necessarily be the fastest or shortest route.
- the selection of the route along which to guide the driver can be very sophisticated, and the selected route may take into account existing, predicted and dynamically and/or wirelessly received traffic and road information, historical information about road speeds, and the driver's own preferences for the factors determining road choice (for example the driver may specify that the route should not include motorways or toll roads).
- the device may continually monitor road and traffic conditions, and offer to or choose to change the route over which the remainder of the journey is to be made due to changed conditions.
- Real time traffic monitoring systems based on various technologies (e.g. mobile phone data exchanges, fixed cameras, GPS fleet tracking) are being used to identify traffic delays and to feed the information into notification systems.
- PNDs of this type may typically be mounted on the dashboard or windscreen of a vehicle, but may also be formed as part of an on-board computer of the vehicle radio or indeed as part of the control system of the vehicle itself.
- the navigation device may also be part of a hand-held system, such as a PDA (Portable Digital Assistant), a media player, a mobile phone or the like, and in these cases, the normal functionality of the hand-held system is extended by means of the installation of software on the device to perform both route calculation and navigation along a calculated route.
- PDA Portable Digital Assistant
- Route planning and navigation functionality may also be provided by a desktop or mobile computing resource running appropriate software.
- the Royal Automobile Club provides an on-line route planning and navigation facility at http://www.rac.co.uk, which facility allows a user to enter a start point and a destination whereupon the server with which the user's computing resource is communicating calculates a route (aspects of which may be user specified), generates a map, and generates a set of exhaustive navigation instructions for guiding the user from the selected start point to the selected destination.
- the facility also provides for pseudo three-dimensional rendering of a calculated route, and route preview functionality which simulates a user travelling along the route and thereby provides the user with a preview of the calculated route.
- the user interacts with the navigation device to select the desired calculated route, optionally from a list of proposed routes.
- the user may intervene in, or guide the route selection process, for example by specifying that certain routes, roads, locations or criteria are to be avoided or are mandatory for a particular journey.
- the route calculation aspect of the PND forms one primary function, and navigation along such a route is another primary function.
- PNDs During navigation along a calculated route, it is usual for such PNDs to provide visual and/or audible instructions to guide the user along a chosen route to the end of that route, i.e. the desired destination. It is also usual for PNDs to display map information on-screen during the navigation, such information regularly being updated on-screen so that the map information displayed is representative of the current location of the device, and thus of the user or user's vehicle if the device is being used for in- vehicle navigation. An icon displayed on-screen typically denotes the current device location, and is centred with the map information of current and surrounding roads in the vicinity of the current device location and other map features also being displayed.
- navigation information may be displayed, optionally in a status bar above, below or to one side of the displayed map information, examples of navigation information include a distance to the next deviation from the current road required to be taken by the user, the nature of that deviation possibly being represented by a further icon suggestive of the particular type of deviation, for example a left or right turn.
- the navigation function also determines the content, duration and timing of audible instructions by means of which the user can be guided along the route. As can be appreciated a simple instruction such as "turn left in 100 m" requires significant processing and analysis.
- user interaction with the device may be by a touch screen, or additionally or alternately by steering column mounted remote control, by voice activation or by any other suitable method.
- a further important function provided by the device is automatic route recalculation in the event that: a user deviates from the previously calculated route during navigation (either by accident or intentionally); real-time traffic conditions dictate that an alternative route would be more expedient and the device is suitably enabled to recognize such conditions automatically, or if a user actively causes the device to perform route re-calculation for any reason.
- a route to be calculated with user defined criteria; for example, the user may prefer a scenic route to be calculated by the device, or may wish to avoid any roads on which traffic congestion is likely, expected or currently prevailing.
- the device software would then calculate various routes and weigh more favourably those that include along their route the highest number of points of interest (known as POIs) tagged as being for example of scenic beauty, or, using stored information indicative of prevailing traffic conditions on particular roads, order the calculated routes in terms of a level of likely congestion or delay on account thereof.
- POIs points of interest
- Other POI-based and traffic information-based route calculation and navigation criteria are also possible.
- the memory of the PND stores map data used by the PND not only to calculate routes and provide necessary navigation instructions to users, but also to provide visual information to users through the visual display of the PND.

- the GPS is a satellite-radio based navigation system capable of determining continuous position, velocity, time, and in some instances direction information for an unlimited number of users.
- NAVSTAR the GPS incorporates a plurality of satellites which orbit the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.
- the GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal allows the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

- the autostereoscopic display device 206 is utilised to draw a viewer's attention to specific visual objects. Attention is drawn to specific visual objects by presenting those objects at a lower depth, thus closer to the user, than other objects, such as map data. In other words, the perception of depth may be utilised to display important visual objects which require a user's attention forward of other information or visual objects. Depth information associated with important objects or information which is required to be quickly perceived by a user indicates that the object is to be displayed at a lower depth than other less important information.
- one or more of emergency information may be displayed at a lower depth, thus appearing closer to the user, than other information or visual objects deemed less important.
- navigation guidance may be displayed at a lower depth than a map display. In this way, a user may be more likely to obtain guidance information with a short glance at the display device 206.
- a map may be displayed at a depth which is lower than that of the surface of display device 206 in order to provide a view which reduces eye strain of a user.
- depth-perception provided by the display device 206 is utilised to provide a more realistic display of geographical features. For example, a building which is further away from the user is displayed having a greater depth on display device 206 than another building which is closer to a current location of the navigation device 200. That is, a depth at which a geographical feature is displayed on display device 206 is related to a distance of that geographical object from the current location of the navigation device 200. The depth may be proportional to the distance in some embodiments. In some embodiments of the present invention, depth information is utilised to provide an indication of a speed at which a user is driving.
- a horizon of a map displayed on the display device is displayed at a depth related to a speed of travel. That is, as the speed of travel increases, the depth of the horizon increases providing a visual indication of speed. Geographical items displayed on the map may also vary in depth in relation to the horizon to provide a realistic map view.
- navigation information such as direction, lane change information etc.
- a display depth corresponds a time at which the navigation information is required.
- three items of navigation information are shown 710, 720, 730 each indicating an instruction to a user.
- the navigation item 710 indicates to go straight ahead, the second 720 to turn right, and the third to go straight ahead again.
- the three navigation items 710, 720, 730 are displayed for use by a user in chronological order. That is, the first navigation item 710 is required to be performed first, the second 720 second, and so on.
- the three items 710, 720, 73 are simultaneously displayed. However each has a depth relating to its order in the sequence.
- the first item 710 is displayed at a lower depth than the second item 720
- the third item 730 is displayed at a lower depth than the second item 720.
- the user may see all three items 710, 720, 730 and be able to have advance notice of navigation instructions, but also it is easier to perceive immediately upcoming navigation items 710.
- the first navigation item 710 may be displayed at a depth which is projected in front of the screen 260, making it easily appreciated by the user. It will be realised that fewer or more than three navigational items may be displayed to the user.
- depth information is used to enhance a visual appeal of a graphical user interface (GUI) of the navigation device 200.
- GUI graphical user interface
- user controls such as buttons, sliders and the like are displayed on the display device 206 at a different depth to other information, such as map data.
- a control plane having a predetermined may be utilised upon which user controls are displayed. This more easily enables users to discern controls which are to be operated from other displayed information.
- the control pane may be displayed at a surface of the display screen 206 in front of map information.
- user controls are displayed at a first depth and, when operated by a user, are moved to a second depth. For example, a button may be displayed at a first depth on the display device.
- the button when pressed by a user the button is moved to be displayed at a second depth to indicate the user pressing on the button using the touch sensitive screen.
- the display of information on the autostereoscopic display device 206 having depth perception is utilised in combination with 3D audio effects.
- 3D audio effects are utilised to place or project sounds generated by audio output device 208 at a location in three dimensional space to assist in directing the user to an appropriate source of information. For example, when a navigational instruction is provided by the navigation device 200 instructing a user to turn right an accompanying sound effect may be projected to a right hand side of the navigation device 200, thus assisting the user with navigation.
- 3D audio effects may be utilised to warn the user by directing them to a source of warning information, such as by outputting a warning sound projected in front of an instrument dial when a predetermined speed is exceeded, thus directing the user to view a speed instrument dial of a vehicle.
- Embodiments of the present invention improve a display of information to a user of a navigation device by the application of visual depth to displayed information.
- the navigation device may utilise any kind of position sensing technology as an alternative to (or indeed in addition to) GPS.
- the navigation device may utilise using other global navigation satellite systems such as the European Galileo system. Equally, it is not limited to satellite based but could readily function using ground based beacons or any other kind of system that enables the device to determine its geographic location.
- Alternative embodiments of the invention can be implemented as a computer program product for use with a computer system, the computer program product being, for example, a series of computer instructions stored on a tangible data recording medium, such as a diskette, CD-ROM, ROM, or fixed disk, or embodied in a computer data signal, the signal being transmitted over a tangible medium or a wireless medium, for example, microwave or infrared.
- the series of computer instructions can constitute all or part of the functionality described above, and can also be stored in any memory device, volatile or non-volatile, such as semiconductor, magnetic, optical or other memory device.
