How to perform quiz function in interactive navigation {methods of implementing quiz function for interative navigation}

The present invention relates to a method for executing by adding a quiz function to the interactive navigation using the voice recognition function, and more particularly, the vehicle maintains a certain speed or more for a predetermined time while running the driving mode for driving guidance in the navigation. If you have made a quiz to the driver in the navigation to run the quiz function to check the answer, the quiz function in the interactive navigation to pause the quiz function and output the driving guidance when the driving guidance occurs while running the quiz function It is about how to perform quiz function.

Navigation is a device that receives GPS data and displays a map on the screen while guiding the road through voice output. Detailed functions for this include various functions that help the driver drive the car, such as short-range guidance, fast way guidance, speed limit information on the road, speed camera location, speed bumps, etc. Are implemented.

In addition to its normal functions, the navigation also has functions such as DMB, video player, music player, karaoke, games, etc. to prevent driver's drowsiness and reduce freeness while driving.

As an example, there is a 'car navigation system with a game machine' function of Korean Patent Application Publication No. 10-1998-029646 (July 25, 1998). The prior art has a game program embedded in the car navigation system, the front wheel sensor is installed to detect whether the vehicle is running or stationary through the front wheel sensor and transmits this signal to the microprocessor, and only when the vehicle is in the stopped state. Navigation system that allows the user to visually recognize the game program by displaying the game program on the liquid crystal display through the liquid crystal driving unit and output the volume through the speaker so that the user can recognize the sound and enjoy the game. to be.

However, the above-described conventional technology allows the game to be played only when the vehicle is parked and cannot be used while driving. Because of this, it can not relieve boredom when driving for a long time, and also can not be used as a function for preventing drowsy driving on monotonous highway driving. In addition, since the game function is directly driven by the driver, the function is not performed unless the driver's active will.

As another example, the Republic of Korea Patent Publication No. 10-2009-0040995 (2009.04.28.) 'Interactive navigation' is. The prior art is configured to integrate a voice storage system and a voice transmission system in which a voice recognition system for recognizing a driver's voice and a voice storage memory for answering a driver's question are installed inside the navigation. The voice recording memory is configured to store the maximum contents of answers in consideration of various questions that may arise according to the driver's situation, so that the driver may immediately respond to a corresponding question when the driver asks a question while driving or starting the vehicle.

However, since the prior art cannot store all the answers to the various words spoken by the person in the memory, and is configured in a way that the driver asks questions, the driver must go through a thought process for this despite the fact that the driver is driving. Can be.

KR Publication No. 10-1998-029646 Car navigation system equipped with the function of a game machine 1998.07.25. KR Publication No. 10-2009-0040995 Interactive Navigation 2009.04.28.

The present invention has been proposed to solve the above problems, the driver does not directly execute the additional function when driving using navigation, but when the predetermined condition is satisfied, execution starts in the system, relieving drowsiness and drowsiness of the driver The purpose of the present invention is to provide a method of performing a quiz function in the interactive navigation, in which the driver answers the question when the navigation asks a question.

In an interactive navigation system that enables two-way communication with a driver, the driver is given a quiz when it is determined that (a) activating and executing the driving mode of the navigation and (b) the driving speed of the vehicle is longer than a predetermined speed and lasts for a predetermined time. It consists of a step of activating and executing the quiz function to check the answer to the question, (c) if it is determined in step (b) that the driving guidance of the driving mode has occurred the quiz function of step (b) And pause the execution of the driving guidement, and releasing the pause of the quiz function when the driving guidement ends.

In addition, the step of executing the quiz function of the step (b), (b1) outputting the quiz, (b2) the driver's response to the quiz and (b3) in the step (b2) Comparing the voiced driver's answer with the set correct answer, if the driver's answer is correct, outputting a correct answer message, and if the driver's answer is incorrect, outputting an incorrect notification message and (b4) the incorrect answer in step (b3). If the notification message is output, it is determined whether there is a response opportunity that can answer the correct answer. If the answer opportunity remains, go back to step (b2) to recognize the driver's answer again, and if the answer opportunity does not remain, output the correct answer. And (b5) if the total time required for the quiz was determined by determining the total time required for the quiz, the quiz was randomly excluded except for the quiz questions. Then it occurs if the re-run from the (b1) step, at a predetermined time characterized in that it comprises end quizzes.

Quiz function in the interactive navigation of the present invention is a navigation vehicle driving guidance function running the driving mode of the vehicle is running a predetermined quiz to the driver if the driving speed is more than a certain speed for a certain time to check the answer By implementing the quiz function, the quiz function can be executed without the driver's separate operation. When the driving guidance occurs during the quiz function execution, the quiz function can be paused to continue to receive the driving guidance of the navigation.

In addition, when driving on a monotonous road such as a highway, the driver's boredom can be prevented and drowsiness can be prevented, and when the navigation asks a question, the driver can answer the question so that the driving can be safely performed. You can also build common sense by fitting quizzes as a side effect.

1 is a flowchart illustrating a method of executing a quiz function during execution of a driving mode of navigation according to an exemplary embodiment of the present invention.
2 is a flowchart illustrating a procedure of executing a quiz function of navigation according to an exemplary embodiment of the present invention.

Hereinafter, a method of performing a quiz function in the interactive navigation in which a quiz is made when a certain condition is met during the running of the navigation guide function, which is a technical idea proposed by the present invention, will be described with reference to the accompanying drawings.

1 is a flowchart illustrating a method of executing a quiz function when a predetermined condition is determined by determining a predetermined condition during execution of a driving mode for driving a vehicle of navigation according to an exemplary embodiment of the present invention. 2 is a flowchart illustrating a procedure of executing a quiz function of navigation according to an exemplary embodiment of the present invention.

As shown in Figure 1, the method of performing a quiz function in the interactive navigation according to an embodiment of the present invention is a driving mode activation step (S10), driving mode execution step (S20), driving speed and time determination step ( S30), quiz function activation step (S40), quiz function execution step (S50), driving guidance generation determination step (S60), quiz function pause step (S70), driving mode driving guide step (S80), quiz function pause It comprises a release step (S90). However, the flowchart of FIG. 1 is merely an embodiment for describing the technical idea of the present invention, and various modifications and substitutions may be made by a person having ordinary skill in the art, various components, and the like. Will be implemented.

First, the driving mode activation step (S10) is a step of preparing to run by booting the driving mode to start the driving information guide function of the navigation. In this case, the driving mode according to the present invention refers to a mode for providing a driving information guide function, which is a main function of navigation, such as road guidance, speed limit information in the road, speed violation camera position notification, speed bump, and the like during vehicle driving.

Next, the driving mode execution step (S20) is a step of performing a driving information guide function. The driving information of the navigation may be output from both the speaker device and the display device of the navigation, which will be the same as the general output method of the navigation driving guide. In addition, since the main function and the main purpose of the navigation is the vehicle driving guide, this step is preferably carried out throughout the entire step of the method of performing the quiz function in the interactive navigation of the present invention.

Next, the driving speed and the driving time determination step (S30) is a step of determining whether the traveling speed of the vehicle is a predetermined speed or more and continues for a predetermined time. The method of performing the quiz function in the interactive navigation according to the present invention has the purpose of reducing the boredom of the driver and preventing the drowsiness during the driving of the highway, so that the vehicle speed during the driving of the highway is used as a criterion. Since the driver usually drives for a long time at a speed of 80km / h or more on the highway, it is desirable to determine whether the vehicle running speed is more than 80km / h and lasted about 10 minutes.

If it is determined that the driving speed of the vehicle has not been maintained for a predetermined time of less than 80 km / h or about 10 minutes, the driving mode execution step S20 is continued. Therefore, when the driving speed of the vehicle is higher than the predetermined speed but does not last for a predetermined time or the driving speed of the vehicle is maintained below the predetermined speed, the navigation continues to perform the driving information guide function in the driving mode execution step (S20).

On the other hand, if it is determined that the traveling speed of the vehicle is 80km / h or more and lasts for a predetermined time of about 10 minutes, the process proceeds to the next step.

Next, the quiz function activation step (S40) is a step to prepare the execution by booting the quiz function of the navigation. However, as described above in the driving mode execution step (S20), it is preferable that the driving mode continues to be executed, similar to a kind of multitasking concept in which several tasks can be simultaneously performed.

Next, when the quiz function execution step (S50) outputs a quiz that the navigation is stored in the memory unit, the driver speaks the answer, and the navigation executes a function of screening the correct answer or the wrong answer by recognizing the driver's answer. to be. The flow of the quiz function internal execution will be described later.

Next, the driving guide generation determination step (S50) is a step of determining whether the driving guide of the driving mode occurs during the quiz function execution. For this purpose, when the driving guide occurs, the driving mode will transmit the driving guide generation signal to the quiz function and the quiz function will receive the signal.

If it is determined that the driving guidance generation signal does not generate the driving guidance, and maintains the quiz function execution step (S50), and if the driving guidance occurs, the process proceeds to the next step.

The method of judging the occurrence of the driving guidance may be a method of continuously checking whether the driving guidance has occurred at a certain period in the control unit of the navigation, or waiting until the driving guidance occurs, and then checking the change at the time of generating the driving guidance. It can be implemented in a variety of ways, such as.

Next, the quiz function pause step (S70) is a step of stopping not to perform the quiz function for a predetermined time outputting the driving guidance when it is determined that the driving guidance of the driving mode has occurred. In this case, in the quiz function pause release step (S90) to be described later, the current position paused may be stored in the memory unit in order to return the function to the same point as the point in time at which it was paused in this step.

Next, the driving mode driving guidance step (S80) is a step of outputting driving guidance such as road guidance, speed limit information in the road, speed limit camera position notification, speed bump warning, etc. to be. During the quiz function execution, the driving mode is given priority so that the driver can be provided with vehicle driving guidance and information.

Next, the quiz function pause release step (S90) is a step of executing the quiz function paused again after the driving guidance is completed. In the present invention, when re-executing the paused quiz function, it is preferable to perform the first step of the quiz function, but when the quiz function is paused, the execution position of the paused time point is stored in the memory unit, and the quiz function is paused. It is also possible to recall the quiz execution step that was remembered at the time and execute it again from the execution position that was originally stopped.

Hereinafter, a method of performing a quiz function during running mode in the interactive navigation according to an exemplary embodiment of the present invention will be described according to the flow of each step.

First, the driving guidance is executed in the driving mode execution step (S20) through the driving mode activation step (S10) of the navigation, and the driving speed of the vehicle in the driving speed and time determination step (S30) exceeds a predetermined speed and has been maintained for a predetermined time. If it is determined through the quiz function activation step (S40) to perform a quiz function execution step (S50).

If it is determined that the driving guidance of the driving mode has occurred in the running guidance generation determination step (S60) while executing the quiz function, the quiz function is paused in the quiz function pause step (S70), and the driving guidance step of the driving mode (S80). After outputting the vehicle driving guidance through, the quiz function paused again in step (S90) to execute the pause quiz function again.

On the other hand, the above-described quiz function will be described in detail below.

As shown in Figure 2, the order flow of the quiz function according to an embodiment of the present invention is the quiz output step (S51), driver answer voice recognition step (S52), driver answer and correct answer comparison step (S53), correct answer Congratulations message output step (54), incorrect notification message output step (S55), answer opportunity determination step (S56), correct answer output step (S57), quiz time check step (S58), quiz generation step (S59) desirable. However, the flowchart of FIG. 2 is merely an embodiment for describing the technical idea of the present invention, and various changes and replacements may be made by a person having ordinary skill in the art, components, and configuration steps. Will be implemented.

Before describing each quiz function, it is also possible to add a step for selecting a quiz type before outputting the quiz, although not shown in the drawing. For example, a user may select one genre among quizzes classified by genres such as nonsense, sports, social science, music, art, or a method in which various genres are mixed in various genres.

First, the quiz output step (S51) is a step to ask a quiz to the driver. The quiz is preferably output through the speaker device of the navigation, but may be displayed on the display device or both the speaker device and the display device. At this time, the output of the quiz through the speaker device should be applied to a known TTS (Text to Speech) engine. TTS is a function that a computer converts text to speech and reads it. The module that converts text to speech with the TTS function is called TTS engine. These TTS engines can be variously prepared by manufacturer, language (English, Korean, etc.) and voice (male, female, etc.) so that the quiz output can be presented in various versions.

Driver answer voice recognition step (S52) is a step of voice recognition in the navigation of the driver's answer to the quiz questions. Speech recognition is a technology that finds the closest result from the input list of recognition by extracting and analyzing features from the voice of a person delivered to a computer or a voice recognition system through a telephone or a microphone. In contrast to the above-described text to speech (TTS), it may be referred to as a process of connecting an acoustic signal to text. Speech recognition technology is divided into various types according to the classification criteria, and it is divided into speaker dependent recognition technology and speaker independent recognition technology according to the user's scope. According to the word recognition technology, continuous speech recognition technology, dialogue recognition technology. In the present invention, the method of performing a quiz function in the interactive navigation is preferable to use the above-mentioned voice recognition technology.

Next, the driver answer and the correct answer comparing step (S53) is a step of comparing whether the driver answer recognized in the navigation and the quiz correct answer stored in the memory unit of the navigation match.

Next, the correct answer congratulation message output step (S54) is a step of outputting a message for celebrating the correct answer when the driver answer and the quiz answer is compared to the driver answer and the correct answer in step S53 compares the correct answer. The correct answer message is, for example, "Congratulations. You answered correctly." Or "Well done. You're a quiz master." It is preferable that the correct answer congratulatory message is output, and the output phrase can be variously changed.

Next, the incorrect notification message output step (S55) compares the driver answer and the quiz answer in the driver response and the correct answer step (S53) and outputs a message indicating that the driver's answer is incorrect if the driver's answer does not match the correct answer Step. Incorrect notification message, for example, "Wrong. Think again." Or "Not correct. Try again." It is preferable that a message informing that an incorrect answer is outputted, and the output phrase can be variously changed.

Next, the answer opportunity determination step (S56) is a step of determining whether there is a response opportunity that can be corrected again if the driver answer is determined to be incorrect. If there is still an opportunity to return to the driver answer voice recognition step (S52) will give the driver a chance to say the correct answer again. On the other hand, if there are no more opportunities for reply, proceed to the next step.

At this time, the answer opportunity is preferably set to N times, such as 1, 2, 3 times, for this purpose, the answer opportunity may be preset to a fixed value in the control unit of the navigation, so that the user can set the opportunity to match It could be implemented.

On the other hand, although not shown in the drawings, the internal counter is implemented to calculate the answer opportunity, each time the answer opportunity is exhausted. The counter can be calculated in various ways, such as by incrementing the counter, and it is desirable to initialize the counter when the correct answer is correct or when a new quiz is output.

Next, the correct answer output step (S57) is a step that tells the correct answer of the quiz questions when all the opportunities for correct answers are exhausted. For example, "Sorry. The answer to this question is OOO." Or "You lost all your chances. The answer is OOO." It is preferable that a phrase such as is output, and the output phrase can be variously changed.

Next, the quiz time check step (S58) is a step of determining whether a predetermined time has elapsed by checking the time required from the start time of the quiz to the present time. If the quiz function has been progressed for a predetermined time, the quiz function ends and returns to the aforementioned driving mode. On the other hand, if the quiz function is conducted for less than a predetermined time, the next step continues.

Finally, the quiz generation step (S59) is a step for generating a quiz randomly among the remaining problems, except for the quiz that has already been asked among quizzes stored in the memory unit when the quiz mode is less than a predetermined time.

Hereinafter, a method of performing a quiz function in the interactive navigation according to an exemplary embodiment of the present invention will be described according to the flow of each step.

First, in the quiz output step (S51) to convert the quiz problem stored in the navigation to the question to quiz the driver. Next, the driver recognizes the answer to the quiz in the driver answer voice recognition step (S52) and then determines whether the driver answer is the correct answer in the driver answer and the correct answer step (S53). If the driver's answer is recognized as the correct answer, the correct answer congratulatory message output step (S54) outputs the correct answer congratulation message, and if the driver's answer is recognized as an incorrect answer error message output step (S55) incorrect to inform that the driver's answer is incorrect Print a notification message. At this time, if there is an opportunity to determine the correct answer remains in the answer opportunity determination step (S56), if there is a chance to return to the driver answer voice recognition step (S52) and try again to match the quiz, if all the opportunities lost correct answer output In step S57, the driver is notified of the correct answer. In addition, if the predetermined time has not elapsed by calculating the total time that the quiz has been progressed in the quiz time checking step (S58), the quiz that is already out of the quiz stored in the memory unit is excluded from the quiz generation step (S59), and the rest of the quiz is performed. Select randomly to return to the quiz output step (S51) to question the next quiz. If a predetermined time has elapsed, the quiz ends and the vehicle returns to the navigation mode.
