Operation of Information Processing Device
With reference to FIGS. 1 to 11, a description will now be given of the function of the present embodiment, as divided into (1) basic operation, (2) content retrieval operation, and (3) content reproduction operation.
(1) Basic Operation
The information processing device 1 is carried by the user 2. When the user 2 enters a range in which guidance is provided on the guidance target 3, the content reproducing unit 100 of the information processing device 1 reproduces the content information 111 previously registered in the storage unit 11 to provide guidance on the guidance target 3. The content reproducing unit 100 acquires the position information from the position information acquiring unit 17. If any item of the latitude/longitude in the content information 111 illustrated in FIG. 3 is close to the position information, the content reproducing unit 100 outputs guidance content in audio from the audio output unit 14.
Then, if the content reproducing unit 100 reproduces the content information 111, the reproduction history recording unit 101 records, in the reproduction history information 112 illustrated in FIG. 4, the content ID reproduced by the content reproducing unit 100 and the start time and the end time of the reproduction by adding thereto the reproduction history ID.
Further, the user 2 photographs the guidance target 3 by using the imaging unit 16 of the information processing device 1. The photographing unit 102 of the information processing device 1 generates the image information 113 by imaging the guidance target 3 or the like with the imaging unit 16 in accordance with the operation performed by the user 2. The generated image information 113 is stored in the storage unit 11.
Then, the photographing unit 102 records the time of photographing, the storage destination of the generated image information 113, and the position information of photographing in the photographing history information 114 illustrated in FIG. 5.
A description will be given below of an operation performed by the information processing device 1 when the user 2 operates the operation unit 15 of the information processing device 1 to select and display an item of the image information 113 on the display unit 13 and reproduce an item of the content information 111 associated with the selected item of the image information 113.
FIG. 7 is a flowchart illustrating an example of the basic operation of the information processing device 1.
Firstly, the image information selecting unit 105 of the information processing device 1 displays a list of the image information 113 on the display unit 13 in accordance with the operation performed on the operation unit 15 by the user 2, and receives the selection of an item of the image information 113 from the list (S1).
FIG. 11A is a schematic diagram illustrating an example of a configuration of the display unit 13 when displaying the list of the image information 113.
A list display 130a is displayed on the display unit 13, and displays thumbnails 130a1, 130a2, 130a3, and so forth of the image information 113.
Then, the content retrieving unit 103 retrieves an item of the content information 111 corresponding to the selected item of the image information 113 (S2). The retrieval operation of the content retrieving unit 103 will be described in detail in “(2) Content Retrieval Operation.”
Then, if an item of the content information 111 corresponding to the selected item of the image information 113 exists (S3; Yes), the outputting unit 106 displays the selected item of the image information 113 on the display unit 13, and outputs the corresponding item of the content information 111 from the audio output unit 14 (S4). The output operation of the outputting unit 106 will be described in detail in “(3) Content Output Operation.”
FIG. 11B is a schematic diagram illustrating an example of the configuration of the information processing device 1 that displays the selected item of the image information 113 and reproduces the item of the content information 111 corresponding to the selected item of the image information 113.
A selected image display 130b displays the image information 113 selected from the thumbnails 130a1, 130a2, 130a3, and so forth in FIG. 11B. The audio output unit 14 of the information processing device 1 reproduces the corresponding item of the content information 111.
(2) Content Retrieval Operation
Details of the operation at step S2 in FIG. 7 will be described below.
FIG. 8 is a flowchart illustrating an example of the content retrieval operation of the information processing device 1.
Firstly, the content retrieving unit 103 acquires the photographing history information 114 of the item of the image information 113 selected by the image information selecting unit 105 (S20).
If the image information ID of the selected item of the image information 113 described above is “001,” the photographing time is “2012/03/15 10:07:00” according to the photographing history information 114 illustrated in FIG. 5.
Then, the content retrieving unit 103 creates a content retrieval condition based on the acquired photographing history information 114 (S21).
Since the photographing time in the acquired photographing history information 114 is “2012/03/15 10:07:00,” the content retrieving unit 103 sets, as an example of the content retrieval condition, a time period “2012/03/15 10:04:00” to “2012/03/15 10:10:00” ranging from 3 minutes before the photographing time to 3 minutes after the photographing time to the time period in which the content information 111 is retrieved.
The content retrieving unit 103 then retrieves the corresponding item of the content information 111 from the reproduction history information 112 based on the created content retrieval condition (S22).
If a retrieval result is obtained by the retrieval at step S22 (S23; Yes), the correspondence information 115 is created which associates the selected item of the image information 113 with the item of the content information 111 as the retrieval result (S24).
FIG. 9 is a schematic diagram illustrating an example of the relationship between the content retrieval time period as the content retrieval condition and a content reproduction time obtained from the reproduction history information.
According to the reproduction history information 112 illustrated in FIG. 4, there is an overlap between the range from the reproduction start time “2012/03/15 10:00:00” to the reproduction end time “2012/03/15 10:05:00” of the reproduction history ID “0001” and the range “2012/03/15 10:04:00” to “2012/03/15 10:10:00” of the created content retrieval condition. Therefore, a content ID “01003” is associated with the image information ID “001.”
If a plurality of retrieval results are obtained at step S23, the correspondence information 115 associating a plurality of items of the content information 111 with a single item of the image information 113 is created at step S24, as illustrated in FIG. 6.
Further, the operation of retrieving the content information 111 described in “(2) Content Retrieval Operation” may also be performed similarly based on the position information expressed in “latitude/longitude.” In this case, a predetermined range centering on the “latitude/longitude” in the photographing history information 114 is set as the content retrieval condition at step S21, and the correspondence information creating unit 104 associates an item of the content information 111 having “latitude/longitude” included in the content retrieval condition with the item of the image information 113.
(3) Content Output Operation
Details of the operation at step S4 in FIG. 7 will be described below.
FIG. 10 is s flowchart illustrating an example of the content output operation of the information processing device 1.
Firstly, the outputting unit 106 acquires the correspondence information 115 of the selected item of the image information 113 (S40).
If a plurality of content IDs “01003” and “01006” correspond to a single item of the image information 113 (S41; Yes), as in the correspondence information 115 illustrated in FIG. 6, the outputting unit 106 displays titles of the plurality of items of the content information 111 on the display unit 13 (S42) to allow the user to select an appropriate item of the content information 111. The titles of items of the content information 111 are presettable. For example, “Tokyo Tower” is displayed for “01003,” and “Shiba Park” is displayed for “01006.”
If the user performs an operation of selecting an item of the content information 111, the outputting unit 106 receives the operation of selecting an item of the content information 111 (S43), and acquires the selected item of the content information 111 (S44). For example, if “Tokyo Tower” is selected, an item of the content information 111 for the content ID “01003” is acquired.
If a single item of the content information 111 corresponds to a single item of the image information 113 at step S41 (S41; No), the corresponding item of the content information 111 is acquired.
Then, the outputting unit 106 outputs the selected item of the image information 113 and the acquired item of the content information 111 (S45). Herein, as illustrated in FIG. 11B, the outputting unit 106 displays the selected item of the image information 113 on the display unit 13, and outputs the corresponding item of the content information 111 from the audio output unit 14.
In the foregoing embodiment, the time of creating the correspondence information 115 corresponds to the time of selection of the image information 113 by the image information selecting unit 105. The creation of the correspondence information 115, however, may be performed at any time after the generation of the image information 113 and the recording of the photographing history information 114. The any time may be immediately after the generation of the image information 113 and the recording of the photographing history information 114, or the creation of the correspondence information 115 may be performed periodically.
