Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information presenting apparatus which, when other information is acquired during information presentation, stops the information being presented and resumes the information presentation after the interruption information is completely presented.

[0002]

2. Description of the Related Art There is known a device for interrupting and presenting other interrupt information while presenting information presented in a predetermined order (see Japanese Patent Laid-Open No. 2001-28183). In this device, the presentation of information is temporarily stopped while other interrupt information is being output, and when the output of the interrupt information is completed, the reproduction of the temporarily stopped information is restarted.
Accordingly, other interrupt information can be presented even while the information is being presented.

However, when the temporary stop of the information is released and the reproduction of the information is restarted after the output of the interrupt information, the restart is performed from the position where the temporary stop was made. That is, if the place temporarily stopped by the output of the interrupt information is in the middle of the music, the reproduction is restarted from the middle of the music. As described above, there is a problem that the user feels uncomfortable due to the reproduction that suddenly starts in the middle of the music.

It is an object of the present invention to provide an information presenting apparatus and a program for resuming information presented after interruption information is output without a feeling of strangeness.

[0004]

(1) According to the invention of claim 1, presenting means for sequentially presenting a plurality of information read according to a presenting instruction, and presenting by interrupting the sequentially presented information. Information acquisition means for acquiring interrupt information, and when the information acquisition means acquires the interrupt information, the presentation of the information is stopped, the interrupt information is presented, and the information is presented after the interrupt information is presented. And a control unit that detects at least one of an interrupt point and an interrupt time of the interrupt information acquired by the information acquisition unit, and the detection unit detects the interrupt point. The information for restarting the presentation of the interrupt information according to at least one of the interrupt point and the interrupt time. Information presentation device having a resumption point determination unit for determining a restart point is provided.

According to another aspect of the present invention, there is provided a step of causing a computer to sequentially present a plurality of pieces of information read according to a presentation command, and interrupt information presented by interrupting the sequentially presented information. A step of stopping the presentation of the information and presenting the interruption information when the interruption information is obtained, and a step of resuming the presentation of the information after the presentation of the interruption information. A program for, the step of restarting the presentation of the information after the presentation of the interrupt information, a step of detecting at least one of the interrupt point of the acquired interrupt information and the interrupt time of the interrupt information, Interrupt point of this detected interrupt information and interrupt of interrupt information Depending on at least one of the while, the program comprising the step of determining the resumption point of the information is provided.

In the present invention, "information" sequentially presented in accordance with a presentation command is information presented in accordance with a predetermined reproduction order or program, and is a RAM, a ROM, or a carrier provided in a means for providing information. Possible CD, M
D, DVD, MO, semiconductor disk, and other information that can be stored in a hard disk. Not only information that is stored in advance on a CD, but also programs that are acquired by radio broadcasting, television broadcasting, wireless broadcasting, Internet distribution, etc. Including etc. Of course, the content is not limited, and may be music information, image information, or character information. The information may be stored in a compressed format.

The "interruption information" is information presented by interrupting sequentially presented information. Specifically, it is information generated according to the situation, such as traffic information, accident information, weather information, map information, store guide information, tourist information around the own vehicle, message information, and other information.

The "interruption point" is a point at which the interrupt information interrupts the sequentially presented information.
It is possible to specify using an absolute time axis,
It is also possible to specify it as a relative position with respect to the information presented one by one. The position with respect to the information can be expressed by using the time relative to the reference point specified in the information, the relative amount of data, or the address of the information.

Further, the "interruption time" is the time at which the interrupt information is presented, or the data amount of the interrupt information, and can be approximated by the time at which the sequentially presented information is interrupted. The detection of the interrupt time may be performed by measuring the time at which the interrupt information is actually presented, may be calculated from the amount of data included in the interrupt information in advance, or the presented bit rate, or may be detected in advance. The interrupt time included in can be read and detected.

The "restart point" is determined according to at least one of the "interruption point" and the "interruption time". The “restart point” is the position of information restarted after the presentation of interrupt information, and it is possible to specify it using an absolute time axis, or to a reference point (for example, start point) specified in the information. It can be displayed using relative time, relative amount of data, or address of information.

The "interruption point" of the interrupt information is
This is information that indicates where the interrupt information is interrupted in the sequentially presented information. When the interruption information is presented immediately after the presentation of certain information is started and when the interruption information is presented just before the completion of the presentation of certain information, the impression given to the user by the point of restarting the information is It will be different.
For example, assume that the information is music. When the music is just started and interrupted, it is considered that the user feels less uncomfortable if he / she listens again from the beginning. On the other hand, when most of the music is presented and the music is interrupted at the end, it is considered that the user feels less uncomfortable starting from the next music.

Further, the "interruption time" is the length (time,
It is the information that displays whether or not it is interrupted by (including the amount of data). The impression given to the user should be different depending on the point at which the information is restarted, depending on whether the interrupt information is presented for a long time or when the interrupt information is presented for a moment. For example, assume that the information is music. When interruption information is presented for a long time during music reproduction, it is considered that the user feels less uncomfortable when starting to listen from the beginning of the interrupted song or the next song. On the other hand, when the interruption information is presented for only a moment, it is considered that the user does not feel uncomfortable even if he / she starts listening from the place where the interruption was made.

The inventors of the present application pay attention to this point, determine the restart point according to at least one of the interrupt point and the interrupt time, and restart the presentation of the information from the restart point determined after the presentation of the interrupt information. The restart point may be determined based on at least one of the interrupt point and the interrupt time, may be determined based on either one, or may be determined based on both the interrupt point and the interrupt time. Good.

According to the present invention, it is possible to provide an information presenting device and a program for resuming the information presented after the output of the interruption information without a feeling of strangeness.

Also in the program according to claim 8, the terms "information sequentially presented", "interruption information", "interruption point", "interruption time", and "restart point" are the same as those described in claim 1. It is significant.
With this program, the computer achieves the same effect by the same operation as the information presenting apparatus according to claim 1.

(2) According to the second aspect of the present invention, when the interrupt time detected by the detection unit is shorter than the first predetermined time, the restart point determination unit causes the stopped point to be stopped. A program is provided for determining the point of stop of the information as the restart point. Also,
When the interrupt time detected by the detection unit is longer than the first predetermined time and shorter than the second predetermined time that is longer than the first predetermined time, the restart point determination unit is It is desirable to determine a predetermined break point in the stopped information as the restart point (claim 3). In addition, when the interrupt time detected by the detection unit is longer than the second predetermined time, the restart point determination unit is presented to the start point of the stopped information or next to the information. It is desirable to determine one of the start points of information as the restart point (claim 4).

According to another aspect of the invention, when the detected interrupt time is shorter than a first predetermined time, the step of determining the restart point is the stopped operation. A program is provided for determining the point of the information stop as the restart point. In addition, the detected interrupt time is longer than the first predetermined time and is longer than the first predetermined time.
When it is shorter than the predetermined time of, the step of determining the restart point preferably determines a predetermined break point in the stopped information as the restart point (claim 9). In addition, if the detected interrupt time is longer than a second predetermined time, the step of determining the restart point may include a start point of the stopped information or information presented next to the information. It is preferable that any one of the starting points is determined as the restart point (claim 10).

According to the present invention, the restart point after presentation of the interrupt information is determined according to the interrupt time (including time and data amount) of the interrupt information. Interrupt time is first
If it is shorter than the predetermined time, the information stop point is set as the restart point, and the information presentation is restarted from the stopped position. This is because if the interrupt time is relatively short, it is considered that the user will not feel uncomfortable if the reproduction is started from the stop point of the information.

When the interrupt information is longer than the first predetermined time and shorter than the second predetermined time (first predetermined time <second predetermined time), a predetermined information division point is set. The presentation of information is restarted from a point where information is separated well as a restart point. This is because when the interrupt time is neither long nor short, it is considered that the user's discomfort can be suppressed by restarting from a point where the information is separated well.

Further, when the interrupt information is longer than the second predetermined time, the presentation of information is resumed from the start point of the stopped information or the start point of the information presented next to the stopped information. . This is because when the interruption time is long, it is more comfortable for the user to present the information again from the start point of the information rather than to start the information halfway. The first predetermined time and the second predetermined time in claims 2 to 4 and claims 8 to 10 do not have to have the same value, and unless otherwise specified, the first predetermined time and the second predetermined time. The size relationship of is not limited.

[0021] According to the present invention, it is possible to provide an information presenting device and a program for resuming the information presented after the interruption information is output without a feeling of strangeness.

(3) According to the fifth aspect of the invention, when the restart point determining section is the front part of the stopped information, the stop point is stopped. It is preferable to determine a start point of the information that has been set as the restart point, and the restart point determination unit may determine that the interrupt point detected by the detection unit is a rear part of the stopped information. It is preferable that the start point of the information presented after the stopped information is determined as the restart point (claim 6).

According to another aspect of the present invention, in the step of determining the restart point, if the detected interrupt point is a front part of the stopped information, the stop is executed. It is preferable that a start point of the information obtained is determined as the restart point. In addition, the step of determining the restart point, when the detected interrupt point is a rear part of the stopped information, sets a start point of information to be presented next to the stopped information. It is preferable to determine it as the restart point (claim 1
2).

In the present invention, the judgment "when the interrupt point is the front part of the stopped information" or "when the interrupt point is the rear part of the stopped information" is based on the time of the stopped information. It is performed based on the length or the data amount of stopped information. That is, it is determined whether the interrupt point belongs to the predetermined amount portion of the front portion or the predetermined amount portion of the rear portion with reference to the predetermined amount of time of the information and the predetermined amount of data amount of the information. Since the front part or the rear part is preferably determined according to the discomfort felt by the user, the start point or the end point of the information is set as the reference point, and 1 / time (data amount) from the reference point is set. It is also possible to define any quantity such as 2, 1/3, 1/4 as the front part or the back part.

When the interruption point is the front part of the stopped information, it is considered that presenting the stopped information again can reduce the user's discomfort. Therefore, the restart point is the start point of the stopped information, and the restart is performed from the beginning of the stopped information. On the other hand, when the interruption point is the rear part of the stopped information, it is possible to reduce the user's discomfort by presenting the next presented information rather than presenting the stopped information. it is conceivable that. Therefore, the restart point has the information next to the stopped information as the start point, and restarts from the beginning of the information presented after the stopped information.

According to the present invention, it is possible to provide an information presenting apparatus and a program for resuming the information presented after the interruption information is output without a feeling of strangeness.

[0027]

According to the first to twelfth aspects of the present invention, it is possible to provide an information presenting apparatus and a program for resuming the information presented after the interruption information is output without a feeling of strangeness.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The information presentation device 100 of this embodiment is mounted on a vehicle. As shown in FIG. 1, the information presenting apparatus 100 according to the present embodiment includes a presenting unit 3 having a display and / or a speaker for presenting information, and a presenting unit 3.
2 is provided with a control unit 2 for controlling the presentation of the information and an information acquisition unit 1 having a communication function and acquiring interrupt information. The information presented to the presentation means 3 is the information read from the memory according to the presentation command. This memory may be a hard disk (storage medium 4) built in the information presenting apparatus 100, or a transportable CD, MD, DV.
It may be a storage medium 4 such as a D, MO or semiconductor memory. The information presentation device 100 includes a storage medium reading unit 31 that accesses the storage medium 4 to read information and reproduce the information. In this embodiment, the music information stored in the CD is sequentially presented. The presented order is the order according to the presented command and may be the stored order, or the presented command (random reproduction command, skip reproduction command, etc.) input by the user through the audio device including the presentation unit 3.
The order may be according to. The form of the presented information may be any of music data, image data, and character data.

The information acquisition unit 1 interrupts the sequentially presented information and acquires the interrupt information presented. The information acquisition unit 1 has a communication function and a reception function, and interrupt information distributed via a telephone line or the Internet, interrupt information received via a television or radio, wireless communication, an interrupt received from VICS, or the like. Get information. Information handled as interruption information includes traffic information, accident information, weather forecast, tourist information,
Facility information, store information, etc. can be illustrated.

When the information acquisition unit 1 acquires the interrupt information, the control unit 2 stops the sequentially presented information, presents the acquired interrupt information, and stops the information after the interrupt information is presented. Control to restart the presentation of.

Regarding this control, the control means 2 is provided with a detection section 21 for detecting at least one of the interrupt point and the interrupt time of the interrupt information. The detection unit 21 has a timer function and detects a point (timing) at which interrupt information is interrupted and a time (length) at which the interrupt information is presented. The interrupt point and the interrupt time can be calculated based on the absolute time axis, or can be calculated relatively to the information presented sequentially. Further, not only the method of directly detecting the time but also the interrupt point and the interrupt time (length) can be detected based on the data amount, the presented bit rate, and the data address.

Further, the control means 2 has a restart point deciding unit 22 for deciding a restart point at which presentation is restarted after presentation of the interrupt information, in accordance with at least one of the detected interrupt point and interrupt time. is doing. The restart point 22 is a point at which information is presented after presentation of interrupt information. This restart point can be expressed by using an absolute time axis, or can be expressed as a relative point with respect to sequentially presented information. Also, not only time, but the amount of data,
It can also be expressed using a data address.

Next, the operation of this embodiment will be described with reference to FIG. In this embodiment, upon starting (S10
1) The presenting means 3 reads the music information stored in the CD of the storage medium 4 and sequentially presents the music information (S10).
2). It is assumed that the information acquisition unit 1 acquires the interruption information during the presentation of the music information (S103). Control means 2
Stops the presentation of the music information in order to present the interruption information (S104), and then starts the presentation of the interruption information (S105). Interrupt information is presented (S10
6) When the presentation is completed, the presentation of the interrupt information ends (S107).

The control means 2 controls the presentation of the interrupt information, and at the same time, determines the restart point of the presentation of the information after the presentation of the interrupt information. This processing is preferably performed in parallel with the control of presentation of interrupt information. Specifically, when the information acquisition unit 1 acquires interrupt information (S103), the detection unit 21 detects an interrupt point (S108). This interrupt point is the timing at which the presentation of the interrupt information is started, but it can be approximated to the timing at which the information being presented is stopped to present the interrupt information. The restart point determination unit 22 determines the restart point of the music information based on the detected interrupt point (S109). Based on the determined restart point, restart of presentation of music information is instructed, and the presentation unit 3 restarts presentation of music information (S110).

FIG. 3 shows a subroutine of the process for determining the restart point performed in S109 of FIG. When the process for determining the restart point is started (S201), the interrupt point is detected (the interrupt point already detected and temporarily stored may be read) (S202), and the interrupt time t is detected (S203). Be seen.

The determination of the restart point according to the interrupt time will be described. The detected interrupt time is stored in advance in association with the information restart point. An example thereof is shown in FIG. In the example shown in FIG. 4, the interrupt time length is short (t <30 seconds), and the interrupt time length is medium (3
0 second <t <2 minutes), long interrupt time (t> 2)
The interruption time is divided into three stages of "minutes", and the restart point is associated with the interruption time. Specifically, when the interruption time is short, the presentation is restarted from the interruption point. This is because, since the interruption time is short, the interruption of information is also short, and it is considered that presenting again from an interrupted point does not make the user feel uncomfortable. If the interruption time is medium, the presentation is restarted from a point in the information where the connection is good. The point where the connection is good is the point where the information is well separated so that the user does not feel uncomfortable even if the information is suddenly restarted. For example, it is between No. 1 and No. 2 of music information, or an interlude part. If the interrupt time is longer, restart the presentation from the start point of the interrupted song,
The presentation is resumed from the start point of the song presented after the interrupted song. This is because if interruption information is presented for a long time, the user does not feel uncomfortable when restarting from the beginning of the song rather than restarting from the middle of the song. However, in this example, 30 seconds and 2 minutes are used as the threshold values, but this time can be appropriately determined according to the discomfort felt by the user. Of course, the interrupt time length may be divided into any number of steps, and is not limited to the three steps as in this example.

Returning now to FIG. 3, the length of the detected interrupt time is judged. In step 204, it is determined whether the interrupt time is shorter than 30 seconds (S204). If it is shorter than 30 seconds, it is determined that the interruption time is short, and the restart point is determined as the restart point based on the correspondence relationship shown in FIG. 4 (S20).
5).

Subsequently, at step 206, it is judged whether or not the interruption time is included between 30 seconds and 2 minutes. Three
If the time is from 0 second to 2 minutes, it is determined that the interrupt information has a medium length, and the restart point is determined as the restart point, which is a point where the restart point is well connected based on the correspondence relationship in FIG. 4 ( S207). The classification points in the present embodiment are determined in advance according to the content of the information, and the information includes an identifier indicating the classification. Specifically, the interlude part of the music, the narration part, Nos. 1 and 2
Between the number and the like are designated as the division points.

The interrupt time flowing from step 204 and step 206 to step 208 is a time of 2 minutes or more. In this case, it is determined that the interrupt time is long. Referring to the correspondence relationship in FIG. 4, the restart point is the start point of the interrupted song or the start point of the song presented next to the interrupted song.

Which one is determined as the start point is determined according to the interrupt point. This is determined in step 209 from the viewpoint of whether the detected interruption point belongs to the front portion or the rear portion of the music information. In this embodiment, the front part of the music information is defined as the time or data amount of the first half of the whole music information,
The latter part is defined as the time or data amount of the latter half of the entire music information. Of course, the front part and the rear part can be arbitrarily defined.

According to this definition, it is determined whether the detected interrupt point belongs to the front portion or the rear portion of the stopped music information (S209). If the interrupt point belongs to the front part, go to step 211,
The restart point is determined as the start point of the stopped music information. On the other hand, if the interrupt point belongs to the rear part, the process proceeds to step 210, and the restart point is determined to be the start point of the music information presented next to the stopped music information. At the determined restart point, presentation of music information is restarted (S109, S11 in FIG. 2).
0). This restart may be presented by cutting in from the restart point of the music information, by fading in, or by presenting narration. By arranging such a starting method, the user's discomfort can be further reduced.

In the present embodiment, both the interrupt point and the interrupt time are detected, but the restart point can be determined by detecting either one. If only the interrupt time is detected, depending on the length of the interrupt time, S205, S207 and S210 or S2
Determine the restart point according to 11. S210 and S2
It may be determined in advance which step should be followed, as to which of 11 is followed. For example, when the interrupt time is longer than a predetermined time, the start point of the stopped information may be set as the restart point. On the other hand, if only the interrupt point is detected, S202
From S to S209, the restart point is determined to be either the start point of the stopped music piece or the start point of the music piece presented next to the stopped music piece.

As described above, according to this embodiment, the restart point at which the presentation of information is resumed is determined according to the interrupt point and the interrupt time of the interrupt information, so that the interrupt information is presented again. The user can view the information without feeling discomfort.

The above-described embodiments are described for facilitating the understanding of the present invention, and not for limiting the present invention. Therefore, each element disclosed in the above-described embodiment is intended to include all design changes and equivalents within the technical scope of the present invention.
