  The operation unit 32, the audio output unit 33, the first detection unit 34, and the second detection unit 35 are connected to the control unit 23 as shown in FIG.

[Operation of Digital Signage Device 1]
Next, the operation of the digital signage apparatus 1 will be described.
FIG. 3 shows a flowchart of content evaluation processing executed in the digital signage apparatus 1. The content evaluation process is executed in cooperation with the control unit 23 and the program stored in the program storage unit 251 when the digital signage device 1 is powered on.

  First, the control unit 23 causes the projector 24 and the audio output unit 33 to output content (step S1). In the present embodiment, the control unit 23 reads the content information stored in the content information storage unit 252 according to a predetermined schedule, and the content image is displayed on the screen 271 by the projector 24 based on the moving image data of the read content information. Project. Further, the audio output unit 33 outputs the audio of the content based on the audio data of the read moving image data. Note that content output continues even during the processing of steps S2 to S7.

  FIG. 4 is a diagram illustrating an example of the content projected on the screen 271 and the arrangement of the operation buttons of the operation unit 32. As shown in FIG. 4, button-type operation guides 32 a indicating functions assigned to the operation buttons are displayed at positions corresponding to the operation buttons of the operation unit 32 of the content projected on the screen 271. .

  Next, the control unit 23 determines whether or not the movement of the screen 271 is detected by the first detection unit 34 (step S2). For example, the control unit 23 determines that the movement of the screen 271 is detected by the first detection unit 34 when the value detected by the first detection unit 34 is equal to or greater than a predetermined value.

When it is determined that the movement of the screen 271 is detected by the first detection unit 34 (step S2; YES), the control unit 23 determines whether the movement of the pedestal 28 is detected by the second detection unit 35 (step S2). S3). For example, the control unit 23 determines that the movement of the pedestal 28 is detected by the second detection unit 35 when the value detected from the second detection unit 35 is equal to or greater than a predetermined value.
When it is determined that the movement of the base 28 is detected by the second detection unit 35 (step S3; YES), the control unit 23 returns to step S1.
When determining that the movement of the base 28 is not detected by the second detection unit 35 (step S3; NO), the control unit 23 sets the number of points corresponding to the content ID of the content being output from the evaluation result storage unit 253. Then, a predetermined point (in this case, 3 pt) indicating that the viewer is interested in the content being output is “high” (step S4), and the process proceeds to step S7.

  Here, as shown in FIG. 5, when the viewer views the content operation guide 32a and accidentally presses the operation guide 32a displayed (projected) on the screen 271 with the finger F, the screen 271 swings back and forth. The detection value by the first detection unit 34 becomes equal to or greater than a predetermined value. However, even if the operation guide 32a displayed on the screen 271 is not pressed with the finger F, the detection by the first detection unit 34 is performed, for example, when an earthquake occurs or the entire digital signage device 1 is moved. The value may be a predetermined value or more. Therefore, when the movement of the screen 271 is detected by the first detection unit 34, the control unit 23 determines whether the movement of the pedestal 28 is detected by the second detection unit 35, and the movement of the pedestal 28 is detected. If it is determined that the content is not, the viewer evaluates that the content being output is “high” and gives a predetermined number of points (here, 3 pt).

On the other hand, when it is determined in step S2 that the movement of the screen 271 has not been detected by the first detection unit 34 (step S2; NO), the control unit 23 determines whether or not the operation button of the operation unit 32 has been pressed. Judgment is made (step S5).
When it is determined that the operation button of the operation unit 32 has been pressed (step S5; YES), the control unit 23 outputs the viewer to the number of points corresponding to the content ID of the content being output in the evaluation result storage unit 253. A predetermined point (in this case, 1 pt) indicating that the interest in the content is “medium” is added (step S6), and the process proceeds to step S7.
When it is determined that the operation button of the operation unit 32 has not been pressed (step S5; NO), the control unit 23 proceeds to step S7.

  Here, when the operation guide 32a displayed on the screen 271 is pressed, it is considered that the operation guide 32a was pressed without noticing the presence of the operation button. In this case, it is considered that the user concentrated on the contents of the screen 271 and did not notice the operation buttons. Therefore, in this embodiment, when the screen 271 is pressed, the viewer evaluates that the viewer is highly interested in the content, and gives a higher point than when the operation button of the operation unit 32 is pressed. To do.

In step S7, the control unit 23 determines whether or not the content has ended (step S7).
When it is determined that the content has not ended (step S7; NO), the control unit 23 returns to step S2.

When it is determined that the content has ended (step S7; YES), the control unit 23 determines whether or not the preset output stop time of the content has arrived (step S8). In step S8, for example, it is determined whether or not the content output stop time specified in the schedule has arrived, such as the end time of the business hours of the day.
When it is determined that the content output stop time has not arrived (step S8; NO), the control unit 23 returns to step S1, and sends the next content (which may be the same content or different content) to the projector 24 and the audio output unit. In step 33, the content is output.

  On the other hand, when it is determined that the output stop time of the content has arrived (step S8; YES), the control unit 23 evaluates each content based on the number of points stored for each content stored in the evaluation result storage unit 253. Is calculated (step S9). For example, by dividing the number of points of each content by the number of times each content is output (the number of reproductions), the evaluation result is calculated by adjusting the variation in the output conditions between the contents. When the number of times of reproduction of each content is set to be the same due to a schedule or the like, the point number of each content stored in the evaluation result storage unit 253 may be used as the evaluation value of each content as it is.

  And the control part 23 outputs the evaluation result for every content (step S10), and complete | finishes a content evaluation process. In step S10, for example, the content evaluation result is transmitted to an external PC (Personal Computer) or the like by the communication unit 26. Alternatively, the digital signage apparatus 1 may be provided with a printer, and the evaluation result for each content may be printed out by the printer.

  As described above, according to the digital signage apparatus 1, the operation guide 32a indicating the function assigned to the operation button in the content being output is displayed on the screen 271 and the control unit 23 is outputting the content. The content is evaluated based on the detection result of the first detection unit 34 that detects the movement of the screen 271 and the detection result of the second detection unit 35 that detects the movement of the base 28. Therefore, it is possible to use the viewer's action on the screen, such as pressing the operation guide displayed on the screen by mistake, for content evaluation.

  Further, the control unit 23 can evaluate the content more accurately by evaluating the content based on whether or not the operation button is pressed.

  In addition, the description content in the said embodiment is a suitable example of the digital signage apparatus 1 which concerns on this invention, and is not limited to this.

  For example, in the above-described embodiment, the example in which the operation buttons of the operation unit 32 are arranged on the lower side of the screen 271 has been described. However, the operation buttons may be arranged on any of the upper, lower, left, and right sides of the screen 271.

  Moreover, in the said embodiment, although demonstrated taking the case of detecting the motion of the screen 271 accurately using the detection result of the 1st detection part 34, and the detection result of the 2nd detection part 35, and evaluating a content, as an example, As a simple example, only the first detection unit 34 may be used. In this case, for example, the detection result (such as the waveform of the output value) of the first detection unit 34 when the operation guide 32a displayed on the screen 271 is pressed is stored in advance in the storage unit 25 or the like, and the first detection unit Based on the comparison between the detection result 34 and the result stored in the storage unit, it may be determined whether the operation guide 32a of the screen 271 is pressed or whether the digital signage device 1 itself is moved by an earthquake or movement. Good.

In the above embodiment, points are given when the operation guide 32a is pressed and when the operation button is pressed. However, points are given only when the operation guide 32a is pressed. Also good.
Moreover, in the said embodiment, although it was set as the digital signage apparatus using the screen 271, it is not restricted to this, The digital signage apparatus using display parts, such as a display, may be used.

  In addition, the detailed configuration and detailed operation of the digital signage apparatus can be changed as appropriate without departing from the spirit of the invention.
