Description

  The present invention relates to an information presentation apparatus that presents information to a user.

  2. Description of the Related Art A speech reading apparatus that reads out text data of an electronic mail received by a mobile phone or the like by voice is known. When such a voice reading device is mounted on a vehicle and used by a driver, the driver sometimes misses a voice message because he / she is concerned about ambient noise and the like.

Therefore, a speech reading apparatus has been proposed that detects the magnitude of noise generated during driving and adjusts the speed of reading text data in accordance with the magnitude of the noise (see, for example, Patent Document 1). According to this conventional speech reading apparatus, text data is read out slowly when the noise is large, so that the problem that the driver misses the voice message can be solved somewhat.
JP 2003-99080 A

  However, in the conventional speech reading apparatus, if the noise generated during driving increases, listening to the voice message is hindered. That is, when the user's action (driving) and the user's viewing of the presented information (listening of the voice message) are incompatible, the user's action is always given priority and the user views the presented information. (Hereinafter referred to as “information viewing”) is hindered. Therefore, there is also a problem that information viewing is suppressed and important information is missed even when the action is not necessarily highly important, such as during walking.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide an information presentation device in which information viewing is not excessively hindered in a situation where user behavior and information viewing are not compatible.

  In order to achieve the above object, an information presentation apparatus according to the present invention is an information presentation apparatus that presents information to a user, and is an action information acquisition unit that acquires action information related to the user's action, and is important for the user's action. Action importance estimation means for estimating the degree of action importance indicating degree, presentation information acquisition means for acquiring presentation information to be presented to the user, and estimation of viewing importance indicating the importance of the user viewing the presentation information Viewing importance level estimation means, and based on the behavior importance level and the viewing importance level, a compatibility determination means for determining whether the user's behavior and the user viewing the presentation information are compatible, Action changing means for performing a process of changing the action of the user when the action of the user is determined to be incompatible with the user's viewing of the presentation information Characterized in that it comprises a. As a result, in a situation where the user's behavior and information viewing are not compatible, the user is allowed to change the behavior, and thus information viewing is not hindered excessively.

  Specifically, the compatibility determination means, when the action importance is a value greater than a first threshold and the viewing importance is a value greater than a second threshold, It is determined that viewing presentation information is not compatible. Thereby, for example, when both the action importance and the viewing importance are larger than a predetermined value, the user is allowed to change the action.

  Here, the compatibility determination means determines a compatibility indicating the degree of compatibility between the user's behavior and the user viewing the presentation information based on the behavior importance and the viewing importance, The behavior changing means may cause the user to change the behavior based on the compatibility level. Accordingly, not only two determinations of whether or not both are compatible, but also three or more determinations can be made, and the user can change the behavior in three or more ways.

  The information presentation device may further cause the user to change the behavior when the compatibility determination means determines that the user's behavior and the user viewing the presentation information are not compatible, or the presentation information A change determination unit that determines whether to change the presentation method of the display method, a presentation method change unit that changes the presentation method of the presentation information when the change determination unit determines to change the presentation method of the presentation information, You may provide the information presentation means which presents the said presentation information to a user with the presentation method changed by the presentation method change means. As a result, in a situation where the user's behavior and information viewing are not compatible, the user is allowed to change the behavior or the presentation information presentation method is changed. The user's behavior is not excessively hindered.

  In addition, the information presentation device further includes behavior flexibility estimation means for estimating behavior flexibility indicating flexibility for changing the user's behavior, and flexibility for changing the viewing mode of the presentation information. Viewing flexibility estimation means for estimating viewing flexibility, wherein the change determination means causes the user to change the behavior based on the behavior flexibility and the viewing flexibility, or the presentation information You may determine whether to change the presentation method. Accordingly, whether to change the behavior of the user or the method of presenting the presentation information is determined from the viewpoint of behavioral flexibility and viewing flexibility.

  Specifically, the change determination unit determines that the user changes the behavior when the behavior flexibility is higher than the viewing flexibility, and when the viewing flexibility is higher than the behavior flexibility, It determines with changing the presentation method of presentation information. As a result, of the user's behavior and information viewing, the higher flexibility is changed, so that the problem that the lower flexibility is changed can be avoided.

  Here, the compatibility determination means determines a compatibility indicating the degree of compatibility between the user's behavior and the user viewing the presentation information based on the behavior importance and the viewing importance, The change determination means is a behavior change degree indicating a degree of changing the behavior of the user based on the compatibility level, the behavior flexibility and the viewing flexibility, and a presentation indicating a degree of changing the presentation method of the presentation information. At least one of the law change degrees is determined, and the behavior changing unit performs a process of causing the user to change the behavior based on the behavior change degree, and the presentation method changing unit determines the previous presentation method change degree. Based on this, the presentation method of the presentation information may be changed. Accordingly, the combination of the compatibility level, the behavioral flexibility level, and the viewing flexibility level can change the degree to which the user changes the behavior and the degree to change the presentation method of the presentation information. It is possible to change the behavior of the user or change the method of presenting the presentation information.

  In addition, the behavior flexibility estimation means estimates that the behavior flexibility is higher as the number of alternatives for the user's behavior is larger or the influence on the user when the alternative is taken is smaller. Thus, if the number of alternatives and the influence due to the change are taken into account, the accuracy of the estimation process can be increased.

  Further, the viewing flexibility estimation means estimates that the viewing flexibility is higher as the number of alternatives for the viewing mode of the presentation information is larger or when the influence on the user is smaller when the alternative is adopted. To do. Thus, if the number of alternatives and the influence due to the change are taken into account, the accuracy of the estimation process can be increased.

  In addition, the presentation method changing means includes the presentation information presentation size, presentation position, presentation resolution, presentation color, presentation transparency, presentation depth, presentation volume, presentation voice type, playback time, playback state, playback portion, playback granularity, You may change the presentation method about at least one of these. Thus, since the presentation information is presented by various presentation methods, it is possible to present the presentation information by a method suitable for the user's action.

  Further, the behavior changing means causes the user to change the behavior by presenting information indicating that the user is prompted to change the behavior, or by stimulating the user's body. As a result, information indicating that the user is prompted to change the behavior is presented or the user's body is stimulated, so that the user can be surely changed the behavior.

  The present invention can be realized not only as such an information presentation apparatus, but also as an information presentation method using characteristic means provided in such an information presentation apparatus as a step, or by performing these steps as a computer. It can also be realized as a program to be executed. Needless to say, such a program can be distributed via a recording medium such as a CD-ROM or a transmission medium such as the Internet.

  Each functional block in the block diagram (FIG. 3) is typically realized as an LSI which is an integrated circuit. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration.

  Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after the manufacture of the LSI or a reconfigurable processor that can reconfigure the connection and setting of the circuit cells inside the LSI may be used.

  Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology. Biotechnology can be applied.

  In other words, the information presentation apparatus according to the present invention performs an action on a user in a situation where an action having an action importance of a predetermined value or more overlaps with viewing of presentation information having an audience importance of a predetermined value or more. Information to be changed is presented, the presentation information presentation method is changed, or information for changing the behavior of the user is presented and the presentation information presentation method is changed.

  Also, the information presentation device according to the present invention has a predetermined behavioral flexibility in a situation in which an action having an action importance of a predetermined value or more overlaps with viewing of presentation information having a view importance of a predetermined value or more. When the value is greater than or equal to the value or greater than the viewing flexibility, a process for causing the user to change the behavior is performed.

  As is clear from the above description, according to the information presenting apparatus according to the present invention, in a situation where the user's behavior and information viewing are not compatible, the user is allowed to change the behavior, and thus information viewing is excessive. I can't interfere. Therefore, it is avoided that important information is missed due to an unimportant action, and the user can surely obtain appropriate information at an appropriate timing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a state in which a user wears an HMD (Head Mounted Display) according to the present invention. The HMD is an information presentation device shaped like a goggle or a helmet, and includes a computer 11 that performs various controls for presenting information to the user, a display device 12 such as an LCD (Liquid Crystal Display), and a user's An optical element (presentation curtain) 13 disposed in front of the eyes, a headphone 14 for voice guidance, a mounting member 15 for mounting the HMD on the head of the user 1, and for receiving presentation information from the Internet or the like A receiver 16.

  One surface of the optical element 13 is a concave aspherical surface, and a half mirror film is applied thereon to reflect information displayed on the display device 12 to form a virtual image. Further, since the other surface of the optical element 13 is a convex aspherical surface so that the outside world can be observed, the user can visually recognize the information displayed on the display device 12 so as to overlap the outside world. become.

  FIG. 2 is a diagram illustrating a state in which the user is wearing another HMD according to the present invention. The HMD includes a storage unit 18 that stores presentation information in advance and a cable 17 that connects the storage unit 18 to the computer 11 instead of the receiver 16 shown in FIG. The storage unit 18 may be realized by a personal computer, for example, and the personal computer may be connected to a LAN (Local Area Network), the Internet, or the like.

  FIG. 3 is a functional block diagram of a main part of the HMD (information presentation device) shown in FIG. This information presentation device is a device that presents information to the user. Functionally, the information presentation device 101, the behavior importance level estimation unit 102, the presentation information acquisition unit 103, and the viewing importance level estimation unit 104 are functionally presented. And a compatibility determination unit 105, a change determination unit 108, a behavior flexibility estimation unit 106, a behavior change unit 109, a presentation method change unit 110, and an information presentation unit 111.

  The behavior information acquisition unit 101 is a camera, GPS (Global Positioning System), acceleration sensor, tilt sensor, magnetic sensor, electronic tag sensor, or the like that acquires behavior information. The behavior information is information related to the user's behavior. Specifically, the current position of the user, the direction and speed of the user's movement, the physical state of the user (the position, orientation, posture, and position of each part of the body such as the head and eyes) Heart rate, body temperature, etc.) and surrounding conditions that affect the user's behavioral state (type and state of the road while walking, type and state of the vehicle being used, type and state of what you are wearing, surroundings This is information on the type of object, person, sound, sight, air, sunlight, etc. and its state), past action history, future action schedule (destination and commuting route), and the like.

  The behavior importance level estimation unit 102 estimates the behavior importance level based on the behavior information. The action importance is a degree indicating how unsuitable the user's action is for viewing information. The action importance becomes higher as the action requires information processing ability such as attention and judgment and physical ability such as muscle strength and instantaneous power. When the action importance level is represented by five levels from “1” to “5”, the highest action importance level is set to “5” and the lowest action importance level is set to “1” (described below). The same applies to viewing importance, compatibility, behavioral flexibility, and viewing flexibility).

  The presentation information acquisition unit 103 is a communication I / F that acquires presentation information. The presentation information is information presented to the user, and specifically, is a moving image such as a TV program or a camera-captured image acquired by broadcasting or communication, text, a still image, a message, a signal, or the like.

  The viewing importance level estimation unit 104 estimates the viewing importance level based on the presentation information. The viewing importance is a degree indicating how important viewing information is for the user. The importance of viewing increases as the information on the main points and the information that the user is interested in.

  The compatibility determination unit 105 determines the compatibility based on the action importance and the viewing importance. The degree of compatibility is a degree indicating a low level of obstacle when simultaneously performing user behavior and information viewing. By simultaneously performing the user's action and information viewing, the degree of compatibility increases as the number of troubles such as a decrease in speed or failure of the user's action actually increases or increases. Similarly, when the user's action and information viewing are performed at the same time, the degree of compatibility increases as the number of troubles such as lack of understanding or oversight of the information viewing actually increases or becomes more likely to occur. The degree of compatibility may be expressed as a numerical value, but may be expressed in two levels, such as “compatible” when the numerical value is greater than or equal to a predetermined value and “incompatible” when the numerical value is less than the predetermined value.

  The behavior flexibility estimation unit 106 estimates the behavior flexibility based on the behavior information. The behavior flexibility is a degree indicating the ease of the user's behavior change. The greater the number of alternatives for the user's behavior, or the smaller the effect on the user when the alternative is taken, the higher the behavioral flexibility.

  The viewing flexibility estimation unit 107 estimates the viewing flexibility based on the presentation information. The viewing flexibility is a degree indicating the ease of changing the viewing mode. The viewing flexibility increases as the number of alternatives regarding the viewing mode of the presented information increases, or as the influence on the user when adopting the alternative is small.

  The change determination unit 108 performs a change determination process based on the compatibility level, behavioral flexibility, and viewing flexibility. The content of the change determination process is based on the premise that only one of the user's behavior or the presentation information presentation method is changed. On the premise that both are changed, it may be determined how much of which is changed.

  The behavior changing unit 109 performs processing for causing the user to change the behavior based on the result of the change determination processing. The mode of changing the behavior is not limited. That is, you may start an action that you are not currently doing, you may want to stop an action that you are currently doing, you may not want to start an action that is scheduled to start, or you can continue an action that is scheduled to be stopped It is also possible to change the degree of current or future action (strength, interval, etc.). The method for changing the behavior is not limited. In other words, the state of the device used at the time of action may be changed, information that affects the user's psychological state such as a message or video may be presented, and the user's physical state such as electrical stimulation or temperature stimulation You may give the stimulus which influences.

  The presentation method changing unit 110 changes the presentation method of the presentation information based on the result of the change determination process. The presentation method here includes display method (display size, display position, resolution, color, transparency, depth, etc.), audio presentation method (volume, voice type, etc.), playback method (pause, fast forward, slow play, Frame advance, digest playback, summary playback, partial playback, etc.). The change of the presentation method here includes conversion, summarization, processing, addition, and deletion of all or part of the presentation information.

The information presentation unit 111 is a display device that presents presentation information to the user.
Hereinafter, the operation of the HMD will be described on the assumption that a user wearing the HMD (information presentation device) shown in FIG. 1 is watching a TV drama on a train. FIG. 4 is a flowchart showing the operation of the HMD, and FIG. 5 is a diagram showing a state where a user wearing the HMD is watching a TV drama on the train.

  First, the behavior information acquisition unit 101 acquires behavior information (S1). That is, the user's current position is acquired by the GPS mounted on the HMD, and action information is acquired from the user's schedule based on the current position (for example, near station A) and the current time (for example, 18:00). . FIG. 6 is a diagram showing the contents of the user schedule. As shown in FIG. 6, when the action information acquisition unit 101 holds a schedule L1 in which a schedule “change from each black-out car to an express train at station A” at 18:00 is held, The action information meaning “train transfer” is acquired from the table L1. Such behavior information may be acquired using a service on the Internet, for example.

  Next, the behavior importance level estimation unit 102 estimates the behavior importance level (S2). That is, it is estimated how important the user's action of “transfer train” is (to what extent it is not suitable for information viewing). FIG. 7 is a diagram illustrating an internal configuration example of an action importance list in which user actions and action importance are associated in advance. As shown in FIG. 7, when the behavior importance level estimation unit 102 holds a behavior importance level list L2 in which a user's behavior is associated with a behavior importance level in advance, the behavior importance for “train transfer” is determined. The degree will be estimated to be “3”.

  The behavior importance level list L2 may be created in advance, or the behavior importance level estimation unit 102 may calculate a value when referring to the list. When calculating values, it is necessary to detect the state of body parts such as feet, arms, and eyeballs, movement sensing information, intersections, ticket gates, bicycles, etc. It is preferable to consider the progress status.

  On the other hand, the presentation information acquisition unit 103 acquires presentation information (S3). Here, information on the current scene of the TV drama being played by the HMD is acquired. For example, the metadata given to a TV drama is acquired, and the current scene being reproduced is the introduction part, development part, CM, or central part of the current scene being reproduced from the information described in the metadata. It is determined whether it is a part. The determination method using metadata is described in the id attribute value of the AudioVisualSegment element that defines a plurality of sections included in a drama program in an XML file containing a description based on MPEG-7 (Moving Picture Experts Group 7). A determination method using a character string may be used, or a determination method may be used based on whether or not the character string is referenced in the High Segment Element element. Here, the description will be continued on the assumption that it was found that the “center” of drama A was being reproduced.

  Next, the viewing importance level estimation unit 104 estimates the viewing importance level (S4). That is, it is estimated how important it is for the user to view the “center” of the drama A. FIG. 8 is a diagram illustrating an internal configuration example of a viewing importance list in which presentation information and viewing importance are associated in advance. As shown in FIG. 8, when the viewing importance level estimation unit 104 holds a viewing importance level list L3 in which presentation information (drama A) and viewing importance levels are associated in advance, “ The viewing importance for the “center” is estimated to be “3”.

  Next, the compatibility determination unit 105 determines whether the user's action and information viewing are compatible (S5). For example, when both the action importance level and the viewing importance level are 3 or more, it is determined that the user's action and information viewing are not compatible (hereinafter simply referred to as “incompatible”). Here, since the action importance level and the viewing importance level are both “3”, it is determined that the compatibility is impossible.

  The method of determining whether or not both are compatible is not limited to the method of determining whether or not the behavioral importance and viewing importance are equal to or higher than a predetermined value. For example, a function having the action importance level and the viewing importance level as input values may be defined and determined based on the output value of the function. Or you may make it determine whether it is incompatible or compatible using information (behavior information, presentation information, information showing the presentation method, etc.) other than action importance and viewing importance.

  Here, the behavior flexibility estimation unit 106 estimates the behavior flexibility (S6). That is, a small influence is estimated when the user's action of “train transfer” is changed. FIG. 9 is a diagram illustrating an internal configuration example of a behavior flexibility list in which user behavior and behavior flexibility are associated in advance. As shown in FIG. 9, when the behavior flexibility estimation unit 106 holds the behavior flexibility list L4 in which the user's behavior and the behavior flexibility are associated in advance, the behavior important for “train transfer” is important. The degree will be estimated to be “3”.

  The behavior flexibility list L4 may be created in advance, or the behavior flexibility estimation unit 106 may calculate a value when referring to the list. When calculating the value, whether you can change trains, whether you can reach the destination if you do not change trains, the increased fare to pay, the delay in the time to reach the destination, the severity level when the arrival is delayed, etc. Is preferably taken into account. Here, it is assumed that the behavior flexibility estimation unit 106 holds a timetable, and if it is found that it can be found that it catches up to the express train at the next transfer station without referring to the timetable by referring to this timetable. Yes. That is, since the arrival at the destination is not delayed even if there is no transfer at station A, a relatively large value “3” is calculated as the behavior flexibility.

  On the other hand, the viewing flexibility estimation unit 107 estimates viewing flexibility (S7). That is, the influence of changing the viewing of the “center” of the drama A is estimated. FIG. 10 is a diagram illustrating an internal configuration example of a viewing flexibility list in which presentation information and viewing flexibility are associated in advance. As shown in FIG. 10, when the viewing flexibility estimation unit 107 holds the viewing flexibility list L5 in which the presentation information and the viewing flexibility are associated in advance, the “center” of the drama A The viewing flexibility is estimated to be “2”.

  The viewing flexibility list L5 may be created in advance, or the viewing flexibility estimation unit 107 may calculate a value when referring to the list. When calculating the value, it is easy to understand the content when presented only by voice, easy to recognize the subject when the display size or resolution is reduced, whether or not to pause, and resume playback after pausing It is preferable to consider the ease of remembering the contents until it is done. Here, when the “center” of the drama is presented only by voice, the content is relatively difficult to understand, so a relatively large value “2” is calculated as the viewing flexibility.

  Next, the change determination unit 108 determines whether to change the behavior of the user or to change the presentation method of the presentation information (S8). For example, the behavior flexibility “3” for “train transfer” is compared with the viewing flexibility “2” for “center” of drama A. Here, since the behavioral flexibility “3” is higher than the viewing flexibility “2”, it is determined that the user changes the behavior (behavior change in S8).

  Thereby, the behavior change unit 109 causes the user to change the behavior (S9). FIG. 11 is a diagram illustrating a state where the center of the TV drama is presented to the user. As shown in FIG. 11 (A), when the center of the TV drama is presented on the presentation curtain 13, as shown in FIG. The message M "OK even if continued" is superimposed and presented to the user.

  Thus, when both the action importance level and the viewing importance level are 3 or more, the compatibility determination unit 105 determines that the compatibility is not possible. Here, since the action importance level and the viewing importance level are both “3”, it is determined that the compatibility is not possible.

  When it is determined that the compatibility is not possible in this way, the change determination unit 108 compares the behavior flexibility and the viewing flexibility, and if the behavior flexibility is higher than the viewing flexibility, the behavior change unit 109 Let the user change behavior. Here, since the behavioral flexibility “3” is higher than the viewing flexibility “2”, the user is allowed to change the behavior.

  On the other hand, when the viewing flexibility is higher than the behavior flexibility, the information presenting unit 111 changes the presentation information presentation method (presentation method change in S8 → S10). In this case, for example, the TV drama being played is paused to play the CM, and the TV drama is resumed when the user completes the transfer.

  As is clear from the above description, in the information presentation device according to the present invention, in the situation where compatibility is not possible, when the viewing flexibility is higher than the behavior flexibility, the presentation information presentation method is changed, and conversely When the behavioral flexibility is higher than the viewing flexibility, the user is allowed to change the behavior, so that the user's behavior is excessively prevented as well as preventing the information viewing from being excessively disturbed This can also be prevented.

  Therefore, it is avoided that important information is missed due to an unimportant action, and the user can surely obtain appropriate information at an appropriate timing. Moreover, it is avoided that important actions are restricted for viewing information that is not necessarily important, and the user can surely take appropriate actions at appropriate timing.

  Here, in the case where the compatibility is impossible, it is determined whether to change the behavior of the user or to change the presentation method of the presentation information, but the present invention is not limited to this. That is, when the compatibility is not possible, the user may be allowed to change the behavior. Thus, the conventional problem that information viewing is excessively hindered can be solved even by a configuration in which the presentation information presentation method is not changed. Of course, when this configuration is adopted, the change determination unit 108, the presentation method change unit 110, and the information presentation unit 111 are not necessarily required.

  Here, based on the behavior flexibility and viewing flexibility, it is determined whether to change the behavior of the user or to change the presentation method of the presentation information, but the present invention is not limited to this. It is not something. For example, you may make it determine whether a user changes action based on action importance and viewing importance, or changes the presentation method of presentation information. In this case, the user may change the behavior when the viewing importance is higher than the behavior importance, and conversely, the presentation information presentation method may be changed when the behavior importance is higher than the viewing importance. Of course, when the behavior flexibility and the viewing flexibility are not used, the behavior flexibility estimation unit 106 and the viewing flexibility estimation unit 107 are not necessarily required.

  Further, the change determination unit 108 is based on the compatibility level, the behavioral flexibility level, and the viewing flexibility level, and the behavioral change level indicating the degree to which the user changes the behavior and the presentation method indicating the degree to change the presentation method of the presentation information. The degree of change may be determined. That is, the degree to which the user changes the behavior and the degree to change the presentation method of the presentation information may be changed depending on the combination of the compatibility level, the behavior flexibility, and the viewing flexibility. In this way, for example, when the behavioral flexibility and the viewing flexibility are the same value, by setting the behavioral change degree and the presentation method change degree to the same value, both the user's behavior and the presentation method are set. It can be changed by the same amount. Even if the behavioral flexibility and the viewing flexibility are different values, both the user's behavior and the presentation method are minimally required, such as changing the presentation method of the presentation information complementarily while changing the behavior mainly by the user. It can be changed to a limited extent. Furthermore, either of the operations of S2 and S4 in FIG. 4 may be performed first. That is, it is sufficient that the operations of S2 and S4 are completed by the operation of S5. Similarly, either of the operations of S6 and S7 in FIG. 4 may be performed first. That is, it is sufficient that the operations of S6 and S7 are completed by the operation of S8. Of course, each operation shown in FIG. 4 may be performed immediately one after another, may be performed in parallel, or may be performed at intervals.

  Furthermore, although the action importance / viewing importance / behavior flexibility / viewing flexibility is represented by an integer value such as 1 or 2 here, the present invention is not limited to this. That is, the importance and flexibility may be information indicating the degree, may be a degree classification, may be a numerical value such as a decimal number, or may be “1 with 20% probability and 80% probability” An expression form with a probability such as “2” is also possible.

  Furthermore, although the transmission type HMD is exemplified here, the present invention is not limited to this. That is, the present invention can also be applied to a sealed HMD that displays an image of the outside world photographed by a camera or the like on a display device such as an LCD while being superimposed on a virtual image. Further, the information presentation unit 111 may include a head-mounted display, a face-mounted display, a glasses-type display, a transmissive display, a retinal scanning display, an information presentation unit 111 of a mobile phone, a mobile TV or a mobile terminal, a projector, and the like. Of course, the present invention can be applied as long as the apparatus includes not only the HMD but also each unit shown in FIG.

  Furthermore, each unit in FIG. 3 may be on one computer or not on one computer. For example, the presentation method change unit 110 and the information presentation unit 111 may be in different devices, and the presentation information acquisition unit 103 may be a server device on the Internet. Moreover, each part may be disperse | distributed on a some computer, and each part (for example, information presentation part 111) in FIG. 3 may exist in multiple numbers on one computer. Of course, each user in FIG. 3 may be shared by a plurality of users.

  Furthermore, although the method for managing the behavior information is not particularly mentioned, a method in which the behavior information acquisition unit 101 itself holds all or part of the behavior information itself may be adopted as this method. A method of holding the position of behavior information so that information can be acquired may be adopted, or a method of holding the position of another behavior information acquisition unit that holds the position of behavior information may be adopted. The same applies to the method of managing the presentation information. That is, the presentation information acquisition unit 103 itself may employ a method of retaining all or part of the presentation information itself, or a method of retaining the position of the presentation information so that the presentation information can be acquired. And the method of holding the position of another presentation information acquisition part which holds the position of presentation information may be employ | adopted.

  The information presenting apparatus according to the present invention is useful as an information presenting apparatus that presents information to a user, particularly as an HMD that does not unduly hinder information viewing in a situation where user behavior and information viewing are not compatible. .
