Description

  The present invention relates to an information presentation system capable of presenting information and inputting information to be presented.

  Conventionally, an information presentation system for presenting information to a driver driving a vehicle has been proposed. Among such information presentation systems, there is a chat-type information presentation system that presents a plurality of information in a chained manner, particularly in the form of a chat (conversation) by a plurality of agents (see, for example, Patent Document 1).

  In this chat-style information presentation system, for example, “There are more shops around here”, “There is a popular Italian restaurant near here,” “That is run by a young couple. Information is presented in a chained fashion in the form of conversation between agents.

  A driver who is a user of an information presentation system can acquire information if he / she listens to a chat by an agent, and does not need to ask the information presentation system to obtain information, but responds to the inquiry from the information presentation system. There is no need. Therefore, such a chat-type information presentation system is suitable for information presentation to a driver who has to pay attention to driving like information presentation in a vehicle.

  Thus, according to the chat-type information presentation system, the user is not forced to ask or respond, but the user can also input in order to obtain more useful information. This input is an input for guiding the development direction of the conversation by the agent so that the user can obtain desired information by intervening in the conversation of the agent. By performing such input, when the user is interested in the conversation by the agent, the conversation can be developed in the direction desired by the user, and more useful information for the user can be obtained.

  Note that the following prior art documents are listed as documents describing the prior art related to the present invention.

  However, in the conventional chat-type information presentation system, when the conversation by the agent is being developed, since the conversation does not directly ask the user, the user can intervene (that is, the user's own input). The timing is difficult to understand.

  In addition, when applying the conventional chat-type information presentation system as an information presentation system for a vehicle driver, in order to reduce the burden of the user's input operation from the viewpoint of ensuring the safety of driving of the driver as a user. In addition, it is conceivable that the input from the user is input by voice. However, due to the imperfection of speech recognition technology, it is difficult to realize highly accurate speech input in a noisy environment such as in a car.

  The present invention has been made in view of the above problems, and can know the timing at which a user can input information that is provided in a chained manner, and can perform input with high accuracy and with a small operation burden.

  In the information presentation system of the present invention, the interface shape control may change the shape of the deformed interface to a shape corresponding to a rotation angle of the steering of the vehicle.

  According to this configuration, when the user rotates the steering wheel, the deformation interface can be deformed so as to reduce the influence on the safe driving, such as forming an input effective area while avoiding a position that is difficult to operate.

  Further, in the information presentation system of the present invention, the interface shape control unit, when there are a plurality of branch points within a predetermined time, the deformation interface is a plurality of ways according to the contents of the plurality of branch points. You may change to a shape in order.

  According to this configuration, the user can know that input is possible for a plurality of branch points.

  According to this configuration, the user can know that input cannot be performed by confirming that the deformation interface is a reference shape by touching the deformation interface with a finger.

  In the information presentation system of the present invention, the presentation information management unit may notify the user that the shape of the deformation interface is to be changed immediately before the shape of the deformation interface is changed.

  According to this configuration, the user need only pay attention to the shape of the deformed interface after receiving the notification, and does not always need to pay attention to the change in the shape of the deformed interface.

It is suitably applied as a system that accepts input.

  FIG. 1 is a block diagram showing a configuration of an information providing system according to an embodiment of the present invention. The information providing system 100 is a system that provides information to users in a chained manner. In particular, the information presentation system 100 of the present embodiment used as an in-vehicle system selects information to be presented based on the position of the vehicle and the processing of the vehicle navigation system. As shown in FIG. 1, the information presentation system 100 according to the present embodiment includes a presentation information database 10, a presentation information management unit 20, an information presentation unit 30, an interface shape control unit 40, a deformation interface 50, an input processing unit 60, and A finger position detector 70 is provided.

  FIG. 2 is a diagram illustrating a transition structure of presentation information stored in the presentation information database 10. As shown in FIG. 2, the presentation information database 10 stores a plurality of pieces of presentation information. The presentation information of the present embodiment is expressed in the XML format. The presentation information is audio data. The plurality of presentation information has a transition structure including a plurality of branch points as a whole. The branch point presentation information includes branch metadata including branch destination information and interface shape information. The presentation information database 10 stores a plurality of presentation information transition structures as shown in FIG.

  In the present embodiment, a stream is formed by the presentation information stored in the presentation information database 10. In the example of FIG. 2, a main stream of presentation information 1-1, presentation information 1-2,... Presentation information 1-5,..., Presentation information 2-1 branched from the presentation information 1-2, presentation A substream of information 2-2,..., A presentation information 3-1 branched from the presentation information 2-2, a substream of presentation information 3-2,..., And a presentation branched from the presentation information 1-3 A substream of information 4-1, presentation information 4-2,... Is illustrated.

  In the present embodiment, when there is no input from the user, the presentation information is presented one after another in the stream, and when there is a branch input from the user, it branches to another substream. The branch metadata is attached to presentation information that can branch to another substream. In the example of FIG. 2, since the presentation information 1-2 can be transferred to the stream of the presentation information 2-1, the presentation information 1-2 is given branch metadata, and the branch destination is the presentation information. 1-3.

  In the example of FIG. 2, each branch point branches only to one different substream, but there may be presentation information that can branch to a plurality of substreams. Further, the presentation information for a plurality of streams may be included in the last presentation information of the stream. In this case, if the user does not make any input, the presentation of the presentation information is stopped.

  In order to provide information to the user in a chained manner, the presentation information management unit 20 follows the transition structure of the presentation information stored in the presentation information database 10 and the input from the user according to the presentation information stored in the presentation information database 10. Manage which ones to present. The presentation information management unit 20 outputs information to be presented to the information presentation unit 30.

  The information presentation unit 30 presents the presentation information received from the presentation information management unit 20. The information presentation unit 30 according to the present embodiment includes a display panel and a speaker, and audio data as presentation information is output as sound from the speaker. In addition, the information presentation part of this invention consists only of a display panel, and presentation information may be text and image information. Moreover, the information presentation part of this invention may consist only of a speaker.

  The interface shape control unit 40 controls the deformation interface 50 to change the shape of the deformation interface 50 based on the presentation information that the presentation information management unit 20 presents to the information presentation unit 30.

  FIG. 3 is an external view of the steering equipped with the deformation interface 50. The deformation interface 50 is provided at a position near the wheel SW on the lateral spoke SS of the steering S. As shown in FIG. 3, this installation position of the deformation interface 50 corresponds to a position where the user can touch with the thumb when the driver as the user grips the steering wheel S at a normal position.

  In the example of FIG. 3, the deformation interface 50 is provided on each of the left and right lateral spokes, but the installation position is not limited to this. One deformation interface 50 may be met. Furthermore, as shown in FIG. 3, the deformation interface 50 of the present embodiment is circular, but may be any shape such as a rectangle.

  The deformation interface 50 can change its own shape and can be mechanically input by the user. That is, the user can perform mechanical input to the deformation interface 50, and the deformation interface 50 is deformed by this input, but the deformation interface 50 is independent of such deformation and is not dependent on external force. You can change the shape yourself.

  FIG. 4 is a cross-sectional view showing the internal structure of the deformation interface 50. The deformation interface 50 includes push-up members 51 arranged two-dimensionally inside. The push-up member 51 is supported by the upper support member 52 and can be freely moved upward (surface direction). A deformation cover 53 serving as a surface of the deformation interface 50 is put on the push-up member 52 supported by the upper support member 52. The deformation cover 53 pushes the push-up member 51 downward, and the push-up member 51 is held at the standard position (lower position) of the upper support member 52 in a state where no push-up force is applied from below.

  The push-up member 51 is pushed up against the deformation cover 53 by the polymer actuator 55 supported by the lower support member 54. The polymer actuator 55 pushes the push-up member 51 upward (surface direction) by the deformation. The polymer actuator 55 shown in FIG. 4 is laminated, but may be a single body.

  The interface shape control unit 40 deforms the shape of the surface of the deformation interface 50 (the surface of the deformation cover 53) into an arbitrary shape by individually controlling the plurality of polymer actuators 55 in the deformation interface 50 having such a structure. Let Specifically, the interface shape control unit 40 can be deformed such that an arbitrary region on the surface of the deformation interface 50 is slightly protruded by being pushed up by the push-up member 51.

  Thus, the area | region which protruded in the surface of the deformation | transformation interface 50 becomes a button. The user can input by pressing the formed button. That is, an area that protrudes on the surface of the deformation interface 50 is set as an input valid area that can be input by pressing it, and an area that does not protrude cannot be input even if it is pressed. It becomes. The deformation interface 50 can set an input effective area having an arbitrary shape under the control of the interface shape control unit 40.

  FIG. 5 is a diagram illustrating a modification of the surface shape of the deformation interface 50. FIG. 5A shows a reference shape in which none of the areas protrudes and no input effective area is formed, and FIG. 5B shows four buttons (input effective area) on the top, bottom, left, and right. FIG. 5C shows an example in which one button (input effective area) is formed in the center, and FIG. 5D shows two buttons (input) on the top and bottom. FIG. 5E shows an example in which a cross-shaped button (input effective region) is formed.

  Returning to FIG. 1, the input processing unit 60 receives and processes an input made by the user to the deformation interface 50, and outputs it to the constant information management unit 20. The finger position detection unit 70 is configured by a contact detection sensor provided on the surface of the deformation interface 50. The finger position detection unit 70 detects which position on the surface of the deformation interface 50 is touched by the finger. The finger position detected by the finger position detection unit 70 is output to the interface shape control unit 40 and the presentation information management unit 20.

  Next, operation | movement of the information presentation system 100 of this Embodiment is demonstrated. FIG. 6 is an operation flowchart of the information presentation system 100. First, the presentation information management unit 20 acquires presentation information to be presented from the presentation information database 10 in order to present information stored in the presentation information database 10 in a chain using the information presentation unit 30 (step S61). ).

  As described above, the presentation information database 10 stores a plurality of transition structures of presentation information as shown in FIG. 2, and the presentation information management unit 20 is based on the position of the vehicle and the processing of the vehicle navigation system. , Select a corresponding one from a plurality of transition structures. When the transition structure shown in FIG. 2 is selected, the presentation information management unit 20 first acquires presentation information 1-1 that is the first presentation information of the main stream of the transition structure.

  Then, the presentation information management unit 20 determines whether or not branching metadata is included in the presentation information acquired from the presentation information database 10 (step S62). If the branch information is not included in the presentation information (NO in step S62), the process returns to step S61 to acquire the next presentation information in the current stream. In the example of FIG. 2, since the branch information is not included in the presentation information 1-1, the process returns to step S61 to obtain presentation information 1-2 that is the next presentation information.

  The presentation information management unit 20 determines whether or not branch metadata is included in the obtained presentation information. If branch metadata is included (YES in step S62), the branch metadata is determined. Is output to the interface shape controller 40, and the interface shape controller 40 deforms the deformed interface 50 in accordance with the acquired interface shape information to set an input effective area (step S63).

  Next, the input processing unit 60 monitors whether there is an input in the input effective area of the modified interface by the user (step S64). If there is no input (NO in step S64), the presentation information management unit 20 returns to step S61 and acquires the next presentation information in the current stream without branching from the current stream. In the example of FIG. 2, the presentation information management unit 20 acquires the next presentation information 1-3 without branching from the presentation information 1-2.

  After the deformation interface 50 is deformed, when an input operation is performed on the deformation interface 50 and the input processing unit 60 receives an input (YES in step S64), the input processing unit 60 displays the input as presentation information. Notify the management unit 20. The presentation information management unit 20 branches the stream according to the input received from the user (step S65).

  In the example of FIG. 2, when the presentation information 1-3 is input to the deformation interface 50 in steps S64 through S61 to S63 and the input processing unit 60 receives an input (step S64). And YES), the input processing unit 60 notifies the presentation information management unit 20 of the input. The presentation information management unit 20 branches the stream according to the input received from the user, and then presents the presentation information 4-1.

  As described above, when there is no input from the user, the information presentation system 100 presents the presentation information one after another in the stream, and when there is input from the user at the branch point, Branch the stream.

  At this time, at the branch point, the interface shape control unit 40 deforms the shape of the deformed interface 50 so as to correspond to the stream branch candidate. For example, when selecting one of up, down, left and right, the deformation interface 50 is deformed so as to form protrusions on the top, bottom, left and right as shown in FIG. When inquiring YES or NO, the deformation interface 50 is deformed so that only one protrusion is formed at the center as shown in FIG. Further, when selecting one of the upper and lower sides, the deformation interface 50 is deformed so as to form protrusions on the upper, lower, left and right as shown in FIG. In these cases, the deformation interface 50 sets an area corresponding to the protrusion as an input effective area.

  Furthermore, when there is no branch metadata in the presentation information presented by the information presentation unit 30, the interface shape control unit 40 sets the modified interface 50 as the reference shape of FIG. In this case, the input valid area is not set in the deformation interface 50, and all user operations on the deformation interface 50 are invalid. That is, the user's input can be rejected by setting the deformation interface 50 as the reference shape.

  Next, an application example of finger position information (finger position information) detected by the finger position detection unit 70 will be described.

(Utilization example 1 of finger position information)
The interface shape control unit 40 acquires finger position information from the finger position detection unit 70 when the deformation interface 50 is deformed. The interface shape control unit 40 determines a position where the protrusion is formed according to the position of the user's finger. For example, when the user's finger is on the edge of the deformed interface 50 and when one protrusion is formed as shown in FIG. 5C, the interface shape control unit 40 moves the user's finger toward the edge on which the user's finger is located. One projecting portion is formed, and an input effective area is set therein.

(Utilization example 2 of finger position information)
The interface shape control unit 40 acquires finger position information from the finger position detection unit 70 when the deformation interface 50 is deformed. The interface shape control unit 40 deforms the deformation interface 50 so that the user's finger is guided to the center of the deformation interface 50 when the user's finger is on the edge of the deformation interface 50. Specifically, when the user's finger is on the edge of the deforming interface 50, the user's finger is directed toward the center by forming a protrusion in order from the region where the user's finger is located toward the center. To do.

(Utilization example 3 of finger position information)
As described above, when the presentation information includes branch metadata, the presentation information management unit 20 outputs this to the interface shape control unit 40. The interface shape control unit 40 changes the shape of the deformed interface 50 based on this branching metadata. At this time, when finger position information is not input from the finger position detection unit 70 to the presentation information management unit 20, or When the notification that the finger cannot be detected is output from the detection unit 70 to the constant information management unit 20, the presentation information management unit 20 alerts the user through the information presentation unit 30. Specifically, the information presentation unit 30 emits a notification sound. In addition, when the information presentation system 100 is provided with the vibration mechanism provided in the steering wheel S, the presentation information management unit 20 may activate the vibration mechanism as an alert to the user.

(Example 4 of using finger position information)
When the shape of the deformation interface 50 is changed by the interface shape control unit 40 and the protrusion is formed on the surface of the deformation interface 50, the presentation information management unit 20 is in the protrusion where the user's finger is formed. When the finger position information is acquired, the information presenting unit 30 is made to output that explains the meaning of pressing the button. Specifically, the information presentation unit 30 explains the meaning of the button touched by the user by voice.

  As described above, according to the information presentation system 100 of the present embodiment, the user is presented with the presentation information in order according to the transition structure, and the user is not asked directly but the user is not asked. When the user can make any input, the shape of the deformation interface 50 is changed to allow the user to input. Therefore, the user does not need to respond to each question. Therefore, when the user does not want to be actively involved in the presentation information (for example, when the user concentrates on driving the vehicle), the information is presented one after another without any user input.

  On the other hand, when the user wants to actively input information to be presented, the deformed interface 50 that is an interface for performing the input is deformed at a timing when the user can input the information. Can know when input is possible. Since the deformation of the deformation interface 50 is deformed corresponding to the input effective area, the user can know how many options can be selected and input.

  Various modifications can be made to the information presentation system 100 described above. Hereinafter, modified examples will be described.

(Modification 1)
For example, the information presentation system 100 may further include a driving load detection unit that detects the driving load of the user. The driving load detection unit notifies the interface shape control unit 40 of detection values related to the driving load such as the vehicle speed and the steering rotation angle. The interface shape control unit 40 changes the shape of the deformed interface 50 regardless of the branching metadata when the vehicle speed and the steering rotation angle are larger than a predetermined threshold, that is, when the driving load is larger than the predetermined threshold. Control not to let it. Thus, when the driving load is large, the shape of the deformation interface 50 is changed, so that the user pays attention to it, and inputs to the deformed deformation interface 50 affect the safe driving. Can be avoided.

(Modification 2)
When there are a plurality of branch points within a predetermined time, the interface shape control unit 40 may sequentially change the deformed interface 50 into a plurality of shapes according to the contents of the plurality of branch points. At this time, the presentation information management unit 20 causes the information presentation unit 30 to output the meaning of each shape of the deformation interface 50. Specifically, the information presentation unit 30 explains the meaning of the shape of the deformed interface 50 deformed by the interface shape control unit 40 by voice.

(Modification 3)
When the input processing unit 60 receives an input from the user, the interface shape control unit 40 may change the deformed interface into another shape according to the content of the input. By doing so, it is possible to cause the user to input in stages.

  For example, when the user first performs an input to select either volume adjustment or frequency adjustment, and volume adjustment is selected, next, input the volume level by forming input effective areas above and below, respectively. When frequency adjustment is selected, the frequency can be adjusted by forming input effective areas on the left and right sides.

  The present invention can notify a user that input can be made to a branch point of information, and has an effect that the user can input with high accuracy, and presents information as well as presenting information. It is useful as an information presentation system or the like that allows input.
