  Embodiments of an information processing apparatus, an operator determination program, and a projection system according to the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited by the following embodiment. Further, the embodiments can be appropriately combined within a range in which the contents are not contradictory.

(Embodiment 1)
[Configuration of Information Processing Device According to Embodiment 1]
The configuration of the information processing apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram illustrating a configuration example of the information processing apparatus according to the first embodiment. 1 will be described using FIG. 2 as appropriate. FIG. 2 is a diagram for explaining the operator determination process according to the first embodiment.

  As illustrated in FIG. 1, the information processing device 100 includes a projection device 10 such as a projector, an imaging device 20 such as a camera, a determination unit 110, a detection unit 120, a storage unit 130, a determination unit 135, and a generation The unit 140 and the output unit 150 are used in scenes such as presentations. In addition, a user who participates in the presentation can operate the projection apparatus 10 as an operation target device by performing a gesture which is an operation performed to operate the projection apparatus 10. Further, the trigger of processing by the information processing apparatus 100 is when the projector 10 is turned on or a setting for using the function of the information processing apparatus 100 is performed.

  The projection device 10 includes a projection unit 11 that projects the image output by the output unit 150 onto a projection surface such as a screen, and a focus state detection unit 12 that detects a focus state with respect to the image projected on the screen. It is a device to be operated. Further, the focus state detection unit 12 obtains the distance from the information processing apparatus 100 to the screen (see FIG. 2) and outputs the distance to the determination unit 110 in the detection of the focus state. The imaging device 20 captures the periphery of the information processing device 100 with a camera and outputs the captured image to the detection unit 120. The detection unit 120 detects the position of each user in the video imaged by the imaging device 20, and outputs the detected position of each user to the determination unit 110.

  The determination unit 110 determines an operator who has an operation right that is a user's right to operate the projection apparatus 10. More specifically, the determination unit 110 acquires the position from the information processing device 100 to each user, which is output by the detection unit 120, and the screen from the information processing device 100 that is output by the focus state detection unit 12. Get the distance to. Then, the determination unit 110 includes a position from the information processing apparatus 100 to each user, a distance from the information processing apparatus 100 to the screen, a position of each user from the information processing apparatus 100 and a position from the information processing apparatus 100 to the screen. And the distance from the screen to each user (see FIG. 2). In FIG. 2, for convenience of explanation, a solid line or a broken line for obtaining the distance to the user closest to the screen is illustrated, but the distance to each of the other users is also obtained in the same manner. Subsequently, the determination unit 110 determines the user closest to the screen as the operator having the operation right. The determination unit 110 that has determined the operator stores information such as the position related to the determined operator in the storage unit 130.

  The detection unit 120 detects a gesture that is an operation performed to operate the projection device 10 among the operations performed by each user, from the video imaged by the imaging device 20. In detection of a gesture performed by each user, the movement of a hand or a finger, which is a part where the gesture is performed, is detected from the difference in user characteristics for each predetermined frame imaged by the imaging device 20, and the movement matches the gesture. Arbitrary techniques, such as a method of detecting a gesture as a gesture, are used. In addition, the detection of the gesture by the detection unit 120 detects not only the gesture by the operator but also the gestures by all users shown in FIG.

  The storage unit 130 stores each gesture and an operation on the projection apparatus 10 corresponding to each gesture in association with each other. More specifically, the storage unit 130 shifts the projection of the image by the projection apparatus 10 to the next page, the previous page, or a specific page, or executes an animation effect in response to a user gesture. Memorize the operation. The storage unit 130 also stores information such as the position related to the operator determined by the determination unit 110.

  The determination unit 135 determines whether or not the gesture detected by the detection unit 120 is a gesture made by the operator determined by the determination unit 110. In determining whether or not the gesture is made by the operator, the information on the position or the like related to the operator stored in the storage unit 130 and the position of the user who performed the gesture detected by the detection unit 120 are within a predetermined distance range. It is determined by whether or not there is (substantially coincides).

  When the determination unit 135 determines that the gesture is a gesture by the operator, the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130. Then, the generation unit 140 generates an image to be projected on the projection device 10 according to the acquired operation, and outputs the generated image to the output unit 150. The output unit 150 outputs the image output by the generation unit 140 to the projection device 10. In response to this, the projection unit 11 of the projection apparatus 10 projects the image output by the output unit 150 onto the screen.

[Flow of operator determination processing according to Embodiment 1]
Next, the flow of the operator determination process according to Embodiment 1 will be described using FIG. FIG. 3 is a flowchart illustrating an example of the flow of the operator determination process according to the first embodiment.

  As illustrated in FIG. 3, the determination unit 110, when starting the process (Yes in step S101), determines the distance from the information processing apparatus 100 to the screen, the distance from the information processing apparatus 100 to each user, and the information processing apparatus. The distance from the screen to each user is calculated from the angle between the position of each user from 100 and the position from the information processing apparatus 100 to the screen (step S102). Here, the trigger for starting the process is when the projector 10 is turned on, or the setting for using the function of the information processing apparatus 100 is performed. Note that the distance from the information processing apparatus 100 to the screen is acquired from the projection apparatus 10, and the distance from the information processing apparatus 100 to each user is obtained from information obtained from the imaging apparatus 20.

  On the other hand, when the process is not started (No at Step S101), the determination unit 110 waits for power-on of the projection apparatus 10 or setting for using the function of the information processing apparatus 100. Then, the determination unit 110 determines the user closest to the screen as an operator who has the operation right of the projection apparatus 10 (step S103).

  Further, the detection unit 120 determines whether a gesture is detected from the video output by the imaging device 20 (step S104). At this time, when it is determined that the gesture is detected by the detection unit 120 (Yes in Step S104), the determination unit 135 determines whether the gesture is determined by the operator determined by the determination unit 110 (Step S105). ). On the other hand, when it is determined by the detection unit 120 that no gesture is detected (No at Step S104), the determination unit 110 executes the process at Step S102 again.

  Further, when the determination unit 135 determines that the gesture is made by the operator (Yes in step S105), the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130, and performs projection according to the acquired operation. An image to be projected on the apparatus 10 is generated (step S106). Thereafter, the output unit 150 outputs the image generated by the generation unit 140 to the projection device 10 (step S107).

[Effects of Embodiment 1]
As described above, the information processing apparatus 100 appropriately obtains the distance from the screen to each user, uses one user who is closest to the screen as an operator, and generates and outputs an image corresponding only to the gesture by the operator. . In response to this, the projection device 10 projects an image corresponding to only the operation according to the gesture of the operator onto the screen. That is, the information processing apparatus 100 gives the operation right of the projection apparatus 10 only to the user who is closest to the screen. As a result, the information processing apparatus 100 progresses the presentation using the projection apparatus 10 as compared with the conventional technique that may impede the progress of the presentation by giving an operation right to a user who is not giving a presentation. Can be made smooth.

(Embodiment 2)
In the first embodiment, the case where the user who is closest to the screen is the operator has been described. However, a user who exists within a predetermined range may be the operator. Therefore, in the second embodiment, a case will be described in which a user in a predetermined range is an operator. In the second embodiment, the function, configuration, and processing of each unit other than the determination unit 110 described below are the same as those in the first embodiment.

[Operator determination processing according to Embodiment 2]
The operator determination process according to the second embodiment will be described using FIG. 4 as appropriate. FIG. 4 is a diagram for explaining an operator determination process according to the second embodiment.

  The determination unit 110 according to Embodiment 2 determines a user who exists within a predetermined range according to the distance from the screen as an operator. More specifically, the determination unit 110 acquires the position from the information processing device 100 to each user, which is output by the detection unit 120, and the screen from the information processing device 100 that is output by the focus state detection unit 12. Get the distance to. Then, the determination unit 110 includes a position from the information processing apparatus 100 to each user, a distance from the information processing apparatus 100 to the screen, a position of each user from the information processing apparatus 100 and a position from the information processing apparatus 100 to the screen. And the distance from the screen to each user (see FIG. 4). In FIG. 4, for convenience of explanation, a solid line for obtaining the distance to the user existing within a predetermined range corresponding to the distance from the screen is shown, but the distance to each of the other users is obtained in the same manner. It is done.

  Subsequently, the determination unit 110 determines a user who exists within a predetermined range (a dashed ellipse shown in FIG. 4) determined according to the distance from the screen as an operator having the operation right. The predetermined range is, for example, a circle with a radius of 70 centimeters centered at a position 1 meter away from the screen in a predetermined direction. Also, as shown in FIG. 4, a plurality of predetermined ranges may exist at any position, and any shape such as an ellipse or a rectangle may be used as long as it has a suitable size. Further, the operator who is a user existing within a predetermined range is determined from the distance (direction) from the screen to each user. In the example of FIG. 4, there is one user for each predetermined range, so these two are operators. However, when there is no user within the predetermined range, there is no user as an operator.

[Flow of operator determination processing according to Embodiment 2]
Next, the flow of the operator determination process according to the second embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of the flow of operator determination processing according to the second embodiment. Note that description of processing similar to the operator determination processing according to Embodiment 1 may be omitted. Specifically, step S201 and step S202 are the same as the processing in step S101 and step S102. Steps S205 to S208 are the same as the processes in steps S104 to S107.

  As shown in FIG. 5, the determination unit 110 determines whether or not the user exists within a predetermined range determined according to the distance from the screen (step S203). Whether or not the user exists within the predetermined range is determined using a distance from the screen to each user, a distance (direction) from the information processing apparatus 100 to the user, or the like. At this time, when the determination unit 110 determines that the user exists within the predetermined range (Yes in step S203), the determination unit 110 performs an operation having an operation right that is an authority to operate the projection apparatus 10 on the user existing within the predetermined range. (Step S204). On the other hand, when determining that the user does not exist within the predetermined range (No at Step S203), the determination unit 110 executes the process at Step S202 again. In the second embodiment, there are cases where the number of operators is not only one but also a plurality of persons. Thereafter, when a gesture by one or a plurality of operators is detected, an image corresponding to the gesture is generated, and the generated image is output to the projection apparatus 10.

[Effects of Embodiment 2]
As described above, since the information processing apparatus 100 uses a user who exists within a predetermined range determined according to the distance from the screen as an operator, when a presentation by a plurality of users using the projection apparatus 10 is performed. , Can make the presentation progress smoothly. In other words, the information processing apparatus 100 sets a predetermined range in the vicinity of a screen in which there are many users who make presentations, and sets all users in the predetermined range as operators. It is possible to facilitate the progress of the presentation using.

(Embodiment 3)
In the first embodiment, the case where the user who is closest to the screen is the operator has been described. However, when the operator is away from the screen by a predetermined distance or more, the gesture by the operator can be invalidated. Therefore, in the third embodiment, a case will be described in which a gesture made by the operator is invalidated when the operator is away from the screen by a predetermined distance or more. In the third embodiment, the functions, configurations, and processes of the units other than the determination unit 110, the determination unit 135, the generation unit 140, and the setting unit described below are the same as those in the first embodiment.

[Operator determination processing according to Embodiment 3]
The operator determination process according to Embodiment 3 will be described using FIG. 6 as appropriate. FIG. 6 is a diagram for explaining an operator determination process according to the third embodiment. In addition, the information processing apparatus 100 according to Embodiment 3 enables the operation of the projection apparatus 10 for each user, which is performed by the user or the system administrator when the operator's operation right is invalidated. A setting unit (not shown) for receiving a setting as to whether or not to set.

  The determination unit 110 according to Embodiment 3 invalidates the operator's operation right (the gesture by the operator) when the operator is away from the screen by a predetermined distance or more. Then, the determination unit 110 sets each user to be different from the operation right when the setting is made to enable the operation of the projection apparatus 10 for each user when the operation right of the operator is invalidated. It is determined as a sub-operator having the sub-operation right that is an authority.

  As illustrated in FIG. 6, when the user who is an operator because the user is the closest user to the screen is separated from the screen by a predetermined distance (for example, 2 meters) or more, the determining unit 110 Disable the operation right you have. As a result, there is no operator. Here, whether or not the operator is away from the screen by a predetermined distance or more depends on the position from the information processing apparatus 100 acquired from the imaging apparatus 20 to each user and the information processing apparatus 100 acquired from the projection apparatus 10 to the screen. It is determined using the distance from the screen to each user obtained from the distance.

  Then, the determination unit 110 determines that the sub operation right for all users is set when the sub operation right that is different from the operation right is set for each user in a state where no operator exists. And each user is determined as a sub-operator. However, if the sub-operation right is not set to be valid for each user, none of the users has the operation right and sub-operation right. Note that the setting as to whether to enable the sub-operation right for each user is set in advance. Further, the sub operation authority may be more limited than the operation authority, and the same operation as the operator may be possible. That is, for convenience of explanation, the names “operator” and “sub-operator” are used differently, but even a sub-operator may be able to perform the same operation as the operator. As a result, when the operator is set to enable the sub-operation right of each user when the operator is away from the screen by a predetermined distance or more, all users including the user who has been the operator until then are It will be decided as a sub operator.

  The determination unit 135 determines whether or not the gesture detected by the detection unit 120 is a gesture made by the sub operator determined by the determination unit 110 in a state in which the sub operation right is set to be valid for each user. Determine whether. In determining whether or not the gesture is made by the sub-operator, the information on the position related to each user stored in the storage unit 130 and the position of the user who performed the gesture detected by the detection unit 120 are within a predetermined distance. It is determined by whether or not there is (substantially coincides).

  When the determination unit 135 determines that the gesture is a gesture by the sub operator, the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130. Then, the generation unit 140 generates an image to be projected on the projection device 10 according to the acquired operation, and outputs the generated image to the output unit 150.

[Flow of operator determination processing according to Embodiment 3]
Next, the flow of the operator determination process according to Embodiment 3 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of the flow of operator determination processing according to the third embodiment. Note that description of processing similar to the operator determination processing according to Embodiment 1 may be omitted. Specifically, steps S301 to S303 are the same as the processes in steps S101 to S103.

  As illustrated in FIG. 7, the determination unit 110 determines whether or not the operator has moved after the operator is determined in Step S303 (Step S304). At this time, when determining that the operator has moved (Yes at Step S304), the determining unit 110 determines whether or not the operator has moved away from the screen by a predetermined distance or more (Step S305). Whether or not the operator has moved or whether or not the operator has moved away from the screen by a predetermined distance or more is obtained from the imaging device 20 or the projection device 10 as appropriate, from the information processing device 100 to each user, and information The determination is made using the distance from the screen to each user obtained from the distance from the processing apparatus 100 to the screen.

  If the determination unit 110 determines that the screen is separated from the screen by a predetermined distance or more (Yes in step S305), is a gesture made by a user other than the operator, that is, a setting for enabling the sub operation right for each user? It is determined whether or not (step S306). On the other hand, when the determining unit 110 determines that the operator is not moving (No at Step S304), when it is determined that the operator is not separated from the screen by a predetermined distance or more (No at Step S305), the process of Step S308 is performed. Executed.

  At this time, when the setting unit 110 is set to enable the sub operation right for each user (Yes in step S306), the determining unit 110 sets all the users as sub operators having the sub operation right. The user's gesture is validated (step S307). On the other hand, when the setting to enable the sub-operation right for each user is not made (No at Step S306), the determination unit 110 executes the process at Step S302 again.

  In addition, the detection unit 120 determines whether or not a gesture has been detected by determining whether or not a user gesture has been acquired from the video obtained from the imaging device 20 (step S308). At this time, when it is determined that the gesture is detected by the detection unit 120 (Yes in step S308), the determination unit 135 determines whether the gesture is determined by the operator determined by the determination unit 110 (step S309). ). On the other hand, when the detection unit 120 determines that a gesture has not been detected (No at Step S308), the determination unit 110 executes the process at Step S302 again.

  In addition, when the determination unit 135 determines that the gesture is made by the operator (Yes in step S309), the generation unit 140 acquires the operation corresponding to the gesture from the storage unit 130, and projects according to the acquired operation. An image to be projected on the apparatus 10 is generated (step S311). On the other hand, when the determination unit 135 determines that the gesture is not an operator gesture (No at step S309), the generation unit 140 determines whether the gesture other than the operator is valid, that is, whether the gesture by the sub-operator is valid. It is determined whether or not (step S310).

  At this time, when the generation unit 140 determines that the gesture by the sub operator is valid (Yes in step S310), the generation unit 140 acquires an operation corresponding to the gesture by the sub operator from the storage unit 130, and responds to the acquired operation. Then, an image to be projected on the projection apparatus 10 is generated (step S311). On the other hand, when the generation unit 140 determines that the gesture by the sub-operator is not valid (No at Step S310), the determination unit 110 executes the process at Step S302 again. After these, the output unit 150 outputs the image generated by the generation unit 140 to the projection device 10 (step S312).

[Effects of Embodiment 3]
As described above, the information processing apparatus 100 invalidates gestures by an operator away from the screen by a predetermined distance or more, and at this time, when the setting by the sub-operator to be valid is made, all users are notified. A sub operation right is given, and an image corresponding to a gesture by each user is generated and output. In other words, the information processing apparatus 100 gives the operation right (sub-operation right) to all users as the presentation by the operator is ended or temporarily interrupted when the operator is away from the screen by a predetermined distance or more. As a result, the information processing apparatus 100 suitably changes the operation right of each user according to the presentation status, and therefore the progress of the presentation using the projection apparatus 10 can be made smoother.

(Embodiment 4)
In the second embodiment, the case where the user who is within the predetermined range is the operator has been described. However, when the operator deviates from the predetermined range, the gesture by the operator can be invalidated. Therefore, in the fourth embodiment, a case will be described in which a gesture made by an operator is invalidated when the operator is out of a predetermined range. In the fourth embodiment, the function, configuration, and processing of each unit other than the determination unit 110, the determination unit 135, the generation unit 140, and the setting unit described below are the same as those in the second embodiment.

[Operator determination processing according to Embodiment 4]
The operator determination process according to the fourth embodiment will be described using FIG. 8 as appropriate. FIG. 8 is a diagram for explaining the operator determination process according to the fourth embodiment. Further, the information processing apparatus 100 according to the fourth embodiment enables the operation of the projection apparatus 10 for each user performed by the user or the system administrator when the operator's operation right is invalidated. A setting unit (not shown) for receiving a setting as to whether or not to set.

  The determination unit 110 according to the fourth embodiment invalidates the operator's operation right (the gesture by the operator) when the operator is out of the predetermined range. Then, when the operation right of the operator is invalidated, the determination unit 110 sets each user as an operation right when the setting of enabling the operation of the projection apparatus 10 is made for each user. It is determined as a sub operator having a sub operation right which is a different authority.

  As shown in FIG. 8, when the user who has been an operator deviates from the predetermined range because it exists within the predetermined range, the determination unit 110 invalidates the operation right possessed by the operator. Here, whether or not the operator is out of the predetermined range is determined based on the distance from the screen to each user, the distance (direction) from the information processing apparatus 100 to each user, or the like.

  Then, the determination unit 110 is set to enable the sub-operation right, which is an authority different from the operation right, for each user in a state where all the operators are out of the predetermined range, that is, there is no operator. In such a case, the sub-operation right for all users is enabled and each user is determined as a sub-operator. However, if the sub-operation right is not set to be valid for each user, none of the users has the operation right and sub-operation right. Note that the setting as to whether to enable the sub-operation right for each user is set in advance. Further, the sub operation authority may be more limited than the operation authority, and the same operation as the operator may be possible. That is, for convenience of explanation, the names “operator” and “sub-operator” are used differently, but even a sub-operator may be able to perform the same operation as the operator. As a result, when all the operators are out of the predetermined range, if the setting for enabling the sub-operation right of each user is made, all the users including the users who have been operators until then are It will be decided as a sub operator.

  The determination unit 135 determines whether or not the gesture detected by the detection unit 120 is a gesture made by the sub operator determined by the determination unit 110 in a state in which the sub operation right is set to be valid for each user. Determine whether. In determining whether or not the gesture is made by the sub-operator, the information on the position related to each user stored in the storage unit 130 and the position of the user who performed the gesture detected by the detection unit 120 are within a predetermined distance. It is determined by whether or not there is (substantially coincides).

  When the determination unit 135 determines that the gesture is a gesture by the sub operator, the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130. Then, the generation unit 140 generates an image to be projected on the projection device 10 according to the acquired operation, and outputs the generated image to the output unit 150.

[Flow of operator determination processing according to Embodiment 4]
Next, the flow of the operator determination process according to Embodiment 4 will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of the flow of operator determination processing according to the fourth embodiment. Note that description of the same processing as the operator determination processing according to Embodiment 2 may be omitted. Specifically, steps S401 to S404 are the same as the processes in steps S201 to S204.

  As illustrated in FIG. 9, the determination unit 110 determines whether or not the operator has moved after the operator is determined in Step S <b> 404 (Step S <b> 405). At this time, when the determination unit 110 determines that the operator has moved (Yes at Step S405), the determination unit 110 determines whether all the operators are out of the predetermined range (Step S406). Whether the operator has moved or whether the operator has moved out of the predetermined range is determined using a distance from the screen to each user, a distance (direction) from the information processing apparatus 100 to the user, or the like. .

  When the determination unit 110 determines that all the operators are out of the predetermined range (Yes in step S406), the determination by the user other than the operator, that is, the setting for enabling the sub operation right for each user is made. It is determined whether or not (step S407). On the other hand, when it is determined by the determining unit 110 that the operator has not moved (No at Step S405), when it is determined that all the operators are not out of the predetermined range (No at Step S406), Step S409 is performed. The process is executed.

  At this time, when the setting unit 110 is set to enable the sub-operation right for each user (Yes in step S407), the determining unit 110 sets all the users as sub-operators having the sub-operation right. The user's gesture is validated (step S408). On the other hand, when the setting for enabling the sub-operation right for each user has not been made (No at Step S407), the determination unit 110 executes the process at Step S402 again.

  Further, the detection unit 120 determines whether or not a gesture has been detected by determining whether or not a user gesture has been acquired from the video obtained from the imaging device 20 (step S409). At this time, when it is determined that the gesture is detected by the detection unit 120 (Yes in step S409), the determination unit 135 determines whether the gesture is determined by the operator determined by the determination unit 110 (step S410). ). On the other hand, when it is determined by the detection unit 120 that no gesture has been detected (No at Step S409), the determination unit 110 executes the process of Step S402 again.

  When the determination unit 135 determines that the gesture is made by the operator (Yes in step S410), the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130, and performs projection according to the acquired operation. An image to be projected on the apparatus 10 is generated (step S412). On the other hand, if the determination unit 135 determines that the gesture is not an operator gesture (No at step S410), the generation unit 140 determines whether the gesture other than the operator is valid, that is, whether the gesture by the sub-operator is valid. It is determined whether or not (step S411).

  At this time, if the generation unit 140 determines that the gesture by the sub operator is valid (Yes in step S411), the generation unit 140 acquires an operation corresponding to the gesture by the sub operator from the storage unit 130, and responds to the acquired operation. Then, an image to be projected on the projection apparatus 10 is generated (step S412). On the other hand, when the generation unit 140 determines that the gesture by the sub-operator is not valid (No at Step S411), the determination unit 110 executes the process at Step S402 again. After these, the output unit 150 outputs the image generated by the generation unit 140 to the projection device 10 (step S413).

[Effects of Embodiment 4]
As described above, the information processing apparatus 100 invalidates a gesture made by an operator who is out of a predetermined range, and at this time, when the setting is made to validate the gesture made by the sub-operator, the sub-operation is performed for all users. A right is generated and an image corresponding to a gesture by each user is generated and output. In other words, the information processing apparatus 100 gives the operation right (sub-operation right) to all users as the presentation by the operator is ended or temporarily interrupted when the operator is out of the predetermined range. As a result, the information processing apparatus 100 suitably changes the operation right of each user according to the presentation status, and therefore the progress of the presentation using the projection apparatus 10 can be made smoother.

(Embodiment 5)
In the first or second embodiment, the case where the gesture by the user other than the operator is invalid has been described, but a specific gesture by the user other than the operator can also be validated. In the fifth embodiment, a case where a specific gesture by a user other than the operator is validated will be described. In the fifth embodiment, the function, configuration, and processing of each unit other than the generation unit 140, the determination unit 110, and the determination unit 135 described below are the same as those in the first or second embodiment.

[Operator determination processing according to Embodiment 5]
The generation unit 140 according to Embodiment 5 generates an image corresponding to a specific gesture when the detected gesture is a specific gesture that can be interrupted even if the gesture is not an operator gesture. More specifically, the determination unit 135 determines whether or not the gesture detected by the detection unit 120 is a gesture made by the operator determined by the determination unit 110. Further, the determination unit 135 determines whether or not the gesture detected by the detection unit 120 is a specific gesture that can be interrupted. In determining whether or not a gesture is capable of being interrupted, an interrupt table that stores whether the operation corresponding to the gesture is interruptible or cannot be interrupted is used.

  FIG. 10 is a diagram illustrating an example of an interrupt table. As illustrated in FIG. 10, the interrupt table stores whether each operation corresponding to the gesture is interruptible or interruptible. For example, the interrupt table stores an operation “next page” corresponding to a gesture and an interrupt “impossible” in association with each other. As another example, the interrupt table stores an operation “enlargement” corresponding to a gesture and an interrupt “permitted” in association with each other. Specifically, according to the example of the interrupt table shown in FIG. 10, when the operation corresponding to the gesture by the user other than the operator is “next page” or “previous page”, the interrupt becomes “impossible” When the operation corresponding to the gesture by the user other than the operator is “enlarge” or “reduced”, the interruption is “permitted”. That is, even for a user who does not have the operation right, an operation such as enlargement or reduction of a page, which is considered not to hinder the presentation, is possible.

  Thus, when the determination unit 135 determines that the gesture is not a gesture by the operator, and the determination unit 135 determines that the gesture is a specific gesture that can be interrupted, the generation unit 140 determines a specific gesture. The corresponding operation is acquired from the storage unit 130. Then, the generation unit 140 generates an image to be projected on the projection device 10 according to an operation corresponding to the acquired specific gesture, and outputs the generated image to the output unit 150.

[Flow of operator determination processing according to Embodiment 5]
Next, the flow of the operator determination process according to the fifth embodiment will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of the flow of operator determination processing according to the fifth embodiment. In addition, FIG. 11 demonstrates the flow of an operator determination process in case the user nearest to a screen is made into an operator. Further, the description of the same processing as the operator determination processing according to Embodiment 1 may be omitted. Specifically, steps S501 to S504 are the same as the processes in steps S101 to S104.

  As illustrated in FIG. 11, when the determination unit 135 determines that a gesture has been detected by the detection unit 120 (Yes in step S <b> 504), the determination unit 135 determines whether the gesture is performed by the operator determined by the determination unit 110. (Step S505). At this time, when the determination unit 135 determines that the gesture is made by the operator (Yes in step S505), the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130, and according to the acquired operation An image to be projected on the projection device 10 is generated (step S507).

  On the other hand, when determining that the gesture is not a gesture by the operator (No at Step S505), the determination unit 135 acquires the operation corresponding to the gesture from the storage unit 130, and uses the interrupt table for the operation corresponding to the acquired gesture. Then, it is determined whether the gesture is a specific interruptable gesture (step S506). At this time, when the determination unit 135 determines that the gesture is a specific interruptable gesture (Yes in step S506), the generation unit 140 generates an image to be projected on the projection device 10 in accordance with an operation corresponding to the gesture. (Step S507). On the other hand, when the determination unit 135 determines that the gesture is not a specific interruptable gesture (No at Step S506), the determination unit 110 executes the process of Step S502 again. After these, the output unit 150 outputs the image generated by the generation unit 140 to the projection device 10 (step S508).

  Next, the flow of the operator determination process according to the fifth embodiment will be described with reference to FIG. FIG. 12 is a flowchart illustrating an example of the flow of operator determination processing according to the fifth embodiment. In addition, FIG. 12 demonstrates the flow of an operator determination process in case the user who exists in a predetermined range is made into an operator. In addition, the description of the same process as the operator determination process according to the second embodiment may be omitted. Specifically, steps S601 to S605 are the same as the processes in steps S201 to S205.

  As illustrated in FIG. 12, when the determination unit 135 determines that a gesture has been detected by the detection unit 120 (Yes in step S <b> 605), the determination unit 135 determines whether the gesture is performed by the operator determined by the determination unit 110. (Step S607). At this time, when the determination unit 135 determines that the gesture is made by the operator (Yes in step S606), the generation unit 140 acquires an operation corresponding to the gesture from the storage unit 130, and according to the acquired operation An image to be projected on the projection device 10 is generated (step S608).

  On the other hand, when determining that the gesture is not a gesture by the operator (No at Step S606), the determination unit 135 acquires the operation corresponding to the gesture from the storage unit 130, and uses the interrupt table for the operation corresponding to the acquired gesture. Then, it is determined whether or not the gesture can be interrupted (step S607). At this time, when the determination unit 135 determines that the gesture is a specific interruptable gesture (Yes in step S607), the generation unit 140 generates an image to be projected on the projection device 10 in accordance with an operation corresponding to the gesture. (Step S608). On the other hand, when the determination unit 135 determines that the gesture is not a specific interruptable gesture (No at Step S607), the determination unit 110 executes the process at Step S602 again. After these, the output unit 150 outputs the image generated by the generation unit 140 to the projection device 10 (step S609).

[Effects of Embodiment 5]
As described above, the information processing apparatus 100 can interrupt an operation by a specific gesture of a user who does not have an operation right other than the operator even while the operator exists. The progress of the presentation using the apparatus 10 can be made smoother. In other words, the information processing apparatus 100 permits an interruption of an operation by a specific gesture that does not hinder the progress of the presentation, and thus the progress of the presentation using the projection apparatus 10 can be made smoother.

(Embodiment 6)
Although the embodiment of the information processing apparatus 100 according to the present invention has been described so far, the present invention may be implemented in various different forms other than the above-described embodiment. Accordingly, different embodiments will be described with respect to (1) changing the operator over time, (2) reappearance of the operator, (3) configuration, and (4) program.

(1) Changing the operator over time In the third or fourth embodiment, when the operator moves away from the screen by a predetermined distance or the operator moves out of the predetermined range, the operator's operation right is invalidated. In the above description, the operation by the gesture of each user is validated. However, the operator may be changed over time. Here, the change of the operator does not change the operation right among the determined operators, but means that the operation based on the gesture of the user who does not have the operation right is made effective over time.

  The flow of the operator determination process when changing the operator over time will be described with reference to FIG. FIG. 13 is a flowchart illustrating an example of the flow of the operator determination process when the operator is changed over time. FIG. 13 illustrates the flow of the operator determination process when the user closest to the screen is the operator. In addition, the description of the same processing as the operator determination processing according to Embodiment 3 may be omitted. Specifically, steps S701 to S703 are the same as the processes in steps S301 to S303. Steps S707 to S713 are the same as the processes in steps S306 to S312.

  As illustrated in FIG. 13, the determination unit 110 determines whether or not the operator has moved after the operator is determined in step S703 (step S704). At this time, when determining that the operator has moved (Yes at Step S704), the determining unit 110 determines whether or not the operator has moved away from the screen by a predetermined distance or more (Step S705). Whether or not the operator has moved or whether or not the operator has moved away from the screen by a predetermined distance or more is obtained from the imaging device 20 or the projection device 10 as appropriate, from the information processing device 100 to each user, and information The determination is made using the distance from the screen to each user obtained from the distance from the processing apparatus 100 to the screen.

  If the determination unit 110 determines that the screen is separated from the screen by a predetermined distance or more (Yes in step S705), whether or not a gesture by a user other than the operator, that is, a setting for enabling the sub-operation right for each user is made. Is determined (step S707). On the other hand, when determining that the operator has not moved (No at Step S704), when determining that the operator has not moved away from the screen by a predetermined distance or more (No at Step S705), whether or not the interrupt disabled time has passed. Is determined (step S706). The interruption impossible time refers to a time during which an interruption operation, which is an operation based on a gesture of a user other than the operator, is impossible. For example, the interruption impossible time is set as 20 minutes when the presentation time is 20 minutes and the question and answer is 10 minutes. That is, after the presentation is finished, an operation right (sub operation right) is given to each user. And if the setting which validates the sub operation right of users other than an operator is made, the progress of subsequent question and answer can be made smooth, without preventing the progress of presentation.

  At this time, when the determination unit 110 determines that the interrupt-disabled time has passed (Yes in step S706), whether or not a gesture by a user other than the operator, that is, a setting for enabling the sub-operation right for each user is made. Is determined (step S707). On the other hand, when it is determined by the determination unit 110 that the interruption impossible time has not passed (No in step S706), the detection unit 120 determines whether or not the user's gesture has been acquired from the video obtained from the imaging device 20. By determining, it is determined whether or not a gesture has been detected (step S709).

  Next, the flow of the operator determination process when the operator is changed over time will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of the flow of operator determination processing when the operator is changed over time. Note that FIG. 14 describes the flow of operator determination processing when a user existing within a predetermined range is an operator. In addition, the description of the same process as the operator determination process according to Embodiment 4 may be omitted. Specifically, steps S801 to S804 are the same as the processes in steps S401 to S404. Steps S808 to S814 are the same as the processes in steps S407 to S413.

  As illustrated in FIG. 14, the determination unit 110 determines whether or not the operator has moved after the operator is determined in Step S804 (Step S805). At this time, when the determination unit 110 determines that the operator has moved (Yes at Step S805), the determination unit 110 determines whether all the operators are out of the predetermined range (Step S806). Whether the operator has moved or whether the operator has moved out of the predetermined range is determined using a distance from the screen to each user, a distance (direction) from the information processing apparatus 100 to each user, or the like. The

  If the determination unit 110 determines that all the operators are out of the predetermined range (Yes in step S806), is a setting made to enable a gesture by a user other than the operator, that is, a sub operation right for each user? It is determined whether or not (step S808). On the other hand, when determining that the operator is not moving (No at Step S805), when the determining unit 110 determines that all the operators are not out of the predetermined range (No at Step S806), the determination unit 110 sets the interruption impossible time. It is determined whether or not it has passed (step S807).

  At this time, if the determination unit 110 determines that the interruption disabled time has passed (Yes in step S807), whether or not a gesture by a user other than the operator, that is, a setting for enabling the sub-operation right for each user is made. Is determined (step S808). On the other hand, when it is determined by the determination unit 110 that the interruption disabled time has not passed (No in step S807), the detection unit 120 determines whether or not a user's gesture has been acquired from the video obtained from the imaging device 20. By determining, it is determined whether or not a gesture has been detected (step S810).

  As described above, the information processing apparatus 100 provides an operation right (sub-operation right) to a user other than the operator as a predetermined time elapses after the presentation starts, and thus provides a question and answer session after the presentation. When such a time is set, it is possible to facilitate the subsequent progress of questions and answers without hindering the progress of the presentation.

(2) Reappearance of operator In the first or second embodiment, the case where the user who is closest to the screen is the operator or the user who is within the predetermined range is the operator has been described. When the operator is away from the screen by more than a predetermined distance or is out of the predetermined range, the screen at that time is recorded, and the screen that is recorded when the operator appears is displayed again. It may be output. Here, the operator who reappears may be a different user from the operator who disappeared when recording a screen.

  A configuration of an information processing apparatus having a function of outputting a recorded screen again will be described with reference to FIG. FIG. 15 is a functional block diagram illustrating a configuration example of an information processing apparatus having a function of outputting a recorded screen again. In FIG. 15, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description of the same components may be omitted.

  As illustrated in FIG. 15, the information processing device 200 includes a projection device 10 such as a projector, an imaging device 20 such as a camera, a determination unit 110, a detection unit 120, a storage unit 130, a generation unit 140, and an output. Unit 250, image information recording unit 260, and regeneration unit 270.

  The image information recording unit 260 records image information regarding the image being projected in the storage unit 130. More specifically, the image information recording unit 260 records image information related to the image projected by the projection device 10 in the storage unit 130 when all the operation rights are invalidated by the determination unit 110. The case where all the operation rights are invalidated is, for example, a case where the operator is away from the screen by a predetermined distance or all operators are out of the predetermined range. The image information is, for example, a display state such as a page number of an image being projected, an enlargement ratio, or a reduction ratio, and is acquired from the projection apparatus 10.

  The regeneration unit 270 acquires image information from the storage unit 130, and regenerates an image based on the acquired image information. More specifically, the regeneration unit 270 displays image information such as a page number and display state from the storage unit 130 when the operator is determined again after the operation right is invalidated by the determination unit 110. get. Then, the regeneration unit 270 regenerates an image based on the acquired image information. Here, the operator who appears again (determined again) may not be the same person as the operator when the image information recording unit 260 records the image information. Thereafter, the output unit 250 outputs the image regenerated by the regenerating unit 270 to the projection device 10. In response to this, the projection unit 11 of the projection apparatus 10 projects the image output by the output unit 250 on the screen.

  Next, the flow of a recorded image re-output process for outputting a recorded image again will be described with reference to FIG. FIG. 16 is a flowchart illustrating an example of the flow of a recorded image re-output process. The recorded image re-output process is executed in parallel with the process flow of each embodiment described above.

  As illustrated in FIG. 16, the image information recording unit 260 determines that the operator determined by the determination unit 110 has moved away from the screen by a predetermined distance or deviated from the predetermined range, and has no operator (Step S <b> 901). (Yes), the image information related to the image being projected is acquired from the projection device 10, and the acquired image information is recorded in the storage unit 130 (step S902). On the other hand, the image information recording unit 260 executes the process of step S901 again while the operator exists (No in step S901). As long as there is no operator, various operations may be performed by gestures of users other than the operator as described in the above embodiment.

  Further, after the operator disappears, the regeneration unit 270 determines whether the operator is determined again by the determination unit 110, that is, whether the operator has appeared (step S903). At this time, when it is determined that an operator has appeared (Yes at Step S903), the regeneration unit 270 acquires image information from the storage unit 130, and regenerates an image based on the acquired image information (Step S904). ). On the other hand, the regeneration unit 270 performs the process of step S903 again while the operator does not appear (No in step S903). The output unit 250 outputs the image regenerated by the regenerating unit 270 to the projection device 10 (step S905).

  As described above, the information processing apparatus 200 records the image information at that time when the operator disappears or the operator changes due to the interruption of the presentation or the operator's break, etc. An image is regenerated and output based on the image information recorded when the person reappears. As a result, the information processing apparatus 200 can make the progress of the presentation using the projection apparatus 10 smoother.

(3) Configuration In addition, information including processing procedures, control procedures, specific names, various data, parameters, and the like shown in the document and drawings can be arbitrarily changed unless otherwise specified. For example, the information stored in the interrupt table is not limited to that shown in the figure, and can be changed as appropriate according to the application.

The projection apparatus 10 and the imaging apparatus 20 are connected to the information processing apparatus 100 or the information processing apparatus 200 via a network, a cable, or the like, and can also be realized as a projection system including these.

  In the first embodiment and the like, an example has been described in which the user who is closest to the screen is the operator, but the user who is closest to the screen and within a predetermined distance from the screen may be the operator. In other words, even if you are in the closest position from the screen, you may not be giving a presentation, such as sitting in a seat, so the user who is closest to the screen and within a predetermined distance from the screen And

  Moreover, although the case where an operator was determined according to the distance from a screen to each user was demonstrated in the said embodiment, you may determine an operator according to the distance from a predetermined position to each user. That is, a user who is closest to a predetermined position that is not a screen, a user who is within a predetermined range corresponding to a distance from the predetermined position, or the like is determined as an operator.

(4) Program FIG. 17 is a diagram illustrating that the operator determination program is realized using a computer. As shown in FIG. 17, a computer 1000 as an information processing apparatus 100 includes a control device such as a CPU (Central Processing Unit) 1001, a ROM (Read Only Memory) 1002, and a RAM (Random Access Memory) connected by a bus 1009.
