Definitions

  • This invention relates to Global Positioning Satellite (GPS) receivers that generate voice messages.
  • GPS Global Positioning Satellite
  • GPS Global Positioning Satellite
  • GPS refers to a navigation technology that relies on a constellation of earth orbiting satellites each of which continuously broadcasts messages that contain the precise time of transmission. From knowledge of the time at which each of a set of satellites transmits its respective message, a receiver can compute the distance to each satellite. The receiver can then determine its own position from the distances to the satellites using Geometric trilateration.
  • GPS receivers While originally developed by the US Department of Defense, civilian use of GPS navigation has proliferated. Advances in technology have made GPS receivers extremely affordable. Indeed GPS receivers for consumer use have become commonplace. Many manufacturers now offer portable GPS receivers useful in motor vehicles. Such GPS receivers include a display that depicts a moving map indicating the position of the motor vehicle during travel. The display can also provide routing information generated by the GPS receiver to direct the driver to a selected location.
  • GPS receivers include text-to speech capability to enable users to hear voice messages typically in the form of driving directions. In this way, the driver of the motor vehicle does not need to monitor the screen constantly in order to follow the driving directions provided by the GPS receiver.
  • most GPS receivers generate voice messages that offer as much information as possible. For example, such voice messages often announce complete street names. For most GPS receivers, the frequency and duration of such voice messages remains fixed, which can prove annoying, especially if voice conversations occur at the time the receiver provides voice messages. Similarly, voice messages from GPS receivers can prove annoying when the messages predominate over audio from a motor vehicles entertainment system.
  • a method for modifying voice messages generated by a Global Positioning Satellite receiver commences with the step of checking whether a voice message established in the GPS receiver can undergo modification. If so, the message undergoes modification when audio above a threshold level is present that could interfere with the voice message.
  • such audio can include, but is not limited voice conversations, such as between the driver and one or more passengers or sound from the vehicle entertainment system (e.g., radio or CD player).
  • Voice message modification can include shortening or delaying the message when appropriate.
  • FIGURE 1 depicts a block schematic drawing of a GPS receiver that practices the voice message modification technique of the present principles
  • FIGURE 2 depicts in flow chart form the steps of a method for modifying voice messages in the GPS receiver of FIG. 1 in accordance with the present principles.
  • FIGURE 1 depicts a block schematic diagram of a Global Positioning Satellite (GPS) receiver 10, which advantageously modifies its voice messages in the presence of audio (e.g., voice conversations and/or music) which would otherwise interfere with the message in accordance with a preferred embodiment of the present principles.
  • the receiver 10 includes an antenna 11 tuned to receive signals transmitted by GPS satellites (not shown) in orbit above the earth.
  • An Intermediate Frequency (IF) circuit 12 processes the satellite signals for input to a processor 14 programmed to establish measure the time of each received signal and then calculate the distance to each satellite. Using the distances from the satellites, the processor 14 can continuously establish its own position.
  • IF Intermediate Frequency
  • the processor 14 communicates with both a Random Access Memory (RAM) 16 and a Read- Only Memory (ROM) 18 to access both stored information, including stored programs and display information, including, but not limited to map data.
  • the processor can execute one or more of programs stored in the ROM 18 to generate display information indicative of the of the GPS receiver position on a moving map using the distance information calculated by the processor and stored in the RAM 16.
  • information and programming stored in the RAM 16 and ROM 18 enable the processor to display location information as well as to generate routing data, e.g., driving directions, to guide a user from one location to another.
  • the processor 14 typically generates voice messages related to the position information via an on-board or an external text- to speech engine (not shown).
  • GPS receivers such as receiver 10
  • a display 20 often in the form of a liquid crystal display (LCD) having touch screen so that a user can both receive and enter data.
  • LCD liquid crystal display
  • the user can enter information in the form of a destination address, triggering the GPS receiver 10 to generate driving instructions that change dynamically based on the displacement of the receiver during vehicle movement.
  • the user can also enter preference and/or profile information as well.
  • the LCD display 20 can display information, including, but not limited to, the instantaneous GPS receiver position, as well as driving instructions to the user-designated destination.
  • the GPS receiver 10 includes an audio reproduction device in the form of a speaker 22 for reproducing the voice messages.
  • the voice messages can include routing information such as, but not limited the names of streets and highways for transiting in order to reach the user-entered destination.
  • GPS receivers To determine the duration and frequency of voice messages generally work well but certain problems exist. In some instances, a road or street can have different names and GPS receivers will generate several voice messages announcing each of the different name. Usually, GPS receivers generate such multiple voice messages when Interstate Highways and State roads intersect and overlap, even though a single voice message announcing one name would suffice.
  • GPS receivers provide one or more voice messages to alert the driver of a next action (waypoint) immediately after the previous waypoint.
  • GPS receivers then repeat the voice message(s) a short distance before the next waypoint to remind the driver to turn.
  • GPS receivers will generate frequent voice messages since the next waypoint typically lies very close to the previous waypoint.
  • the frequency and duration of such voice messages under such circumstances can prove particularly annoying if the driver is engaged in a conversation with one or more passengers or is listening the vehicle entertainment system.
  • a driver can only control voice messages from present day GPS receivers by either reducing the volume or turning off such messages entirely. Turning down the volume or completely muting such voice message could cause the driver to miss an important message.
  • most drivers endure every GPS voice message, including those that are unnecessarily, repetitive or lengthy, thus interrupting any ongoing conversations or listening to the vehicle entertainment system.
  • the GPS receiver 10 advantageously modifies the voice messages in the presence of audio above a threshold to the extent such modification proves feasible.
  • the GPS receiver 10 includes an audio pick-up device 24, typically in the form of a microphone, for sensing audio within the same listening space as the message and for providing such audio to the processor 14.
  • the microphone 24 will pickup any voice conversations and/or audio from the vehicles entertainment system (not shown) and provide corresponding signals to the processor 14 of FIG. 1.
  • the processor 14 will take account of the audio and determine whether modification of voice messages should occur when the audio level exceeds a threshold value.
  • Modification of the voice messages can occur in one or more of the following ways:
  • the voice message could announce only major roadways and not the minor roadways.
  • the voice message could omit announcements for roadways that do not require an action by the driver.
  • the GPS receiver 10 of FIG. 1 could delay delivering a voice message before or after a turn instruction until the level of the audio falls below the threshold value, as typically occurs upon the cessation of a voice conversation or when the driver turns off the vehicle entertainment system. 3. Reduce the volume of non-critical messages
  • the GPS receiver 10 could 5 automatically reduce the audio volume of non-critical instructions upon the detecting that the level of the audio exceeds the threshold value, as will occur during a voice conversation or during playing of the vehicle entertainment system.
  • the GPS receiver 10 of FIG. 1 When delivering a voice message in the presence when the level of audio exceeds the threshold value, the GPS receiver 10 of FIG. 1 also could deliver a supplementary voice message, such as an apology.
  • FIGURE 2 depicts in flow chart form the steps of a method 200 for modifying voice messages of the GPS receiver 10 of FIG. 1 in accordance with a preferred embodiment of the present principles.
  • the method 200 of FIG. 2 commences upon execution of step 202, which occurs when the processor 14 in the GPS receiver 10 of FIG. 1 finds it necessary to generate a voice message, such as when the processor needs to alert a driver to take a certain action.
  • step 204 undergoes execution, whereupon a check occurs whether the level of the audio picked up by the microphone 24 exceeds a threshold value. If the audio level lies below the threshold, the processor 14 of FIG. 1 generates a normal voice message, that is, a voice message not modified any manner.
  • the GPS receiver 10 of FIG. 1 announces the voice message. 5 If the audio level exceeds the threshold value during step 204, the execution of step
  • step 210 occurs and a check occurs during whether the message possesses sufficient importance (i.e., sufficient criticality) to warrant announcement immediately.
  • An important message constitutes a message, which requires prompt action, such as a message instructing the driver to make a turn within in a very short distance. Obviously, the driver should receive such0 messages irrespective of the presence of any audio. However, even though the voice message possesses sufficient importance to warrant immediate announcement, a shortened form of the message could convey the needed information.
  • a check occurs during step 212 whether the message can undergo shortening. If so, the voice message undergoes shortening during step 214 prior to announcing the message during step 208.
  • the message is generated in its entirety during step 206 of FIG. 2.
  • the processor 14 could generate a supplementary message, such as an apology, for interrupting an ongoing conversation or the listening of the vehicle's entertainment system.
  • the voice message When checked during step 210, the voice message might not possess sufficient importance to warrant immediate announcement. Ordinarily, unimportant voice messages should undergo a delay until a determination that the level of the audio no longer exceeds the threshold. However, some voice messages, while not important, cannot undergo a delay.
  • the GPS receiver 10 of FIG. 1 could provide a voice message announcing the distance to a certain intersection to warn the driver of the need to turn the vehicle. If the elapsed distance to the intersection has sufficiently decreased owing so that delaying the message would render it moot (the vehicle has passed the intersection), then the GPS receiver 10 should announce the distance with no further delay.
  • step 216 a check occurs during step 216 whether the voice message can undergo a delay. If so, then the method branches to step 202 for re-execution, thereby delaying the message. Otherwise, the method branches to step 212 for re-execution to announce the message immediately.
  • the foregoing describes a technique for selectively modifying voice messages announced by a GPS receiver upon detecting audio above a threshold level.

Abstract

La présente invention concerne un récepteur de positionnement global par satellite (10) ou "GPS" pourvu d'un micro (24) servant à capter des sons de façon à permettre à un processeur (14) équipant le récepteur de déterminer les cas où le niveau des sons, notamment d'une conversation vocale dans la plage de niveaux d'écoute du récepteur, dépasse un seuil faisant qu'il interfèrerait avec les messages vocaux produits par le récepteur. Tant que le niveau sonore reste au-dessus de la valeur du seuil, le processeur vérifie si les messages vocaux peuvent subir une modification telle qu'un retardement ou un raccourcissement, de façon à ne pas interférer avec une telle conversation vocale.
