Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seating apparatus for objectively predicting how interesting the content of a work such as a movie or video is to an audience before the work is released.

[0002]

2. Description of the Related Art When releasing a new movie or video work, a business operator should objectively determine which part of the work is interesting to the audience and whether or not the whole work is interesting. I want to know. This is because, if you know that in advance, it will be a reference for future work production, and it will also be a great reference for the release scale of the work and the way of advertising in advance. For that reason, in the past, when it was released, there were methods such as following the works that were well received in the past, and holding a preview session in advance to hear the reputation of the work.

[0003]

However, recently, the tastes of the spectators have been diversified, and it becomes difficult for the business operators themselves to grasp what kind of works are popular with the above-mentioned conventional methods. In other words, even if a movie or video production expert makes a new work that follows a well-received work in the past, it often fails because it has already been overwhelmed by the audience. In addition, there was a problem that it was difficult to get an objective evaluation of which part was interesting even if we held a preview and heard the reputation of the new work in advance.

The present invention solves the above-mentioned problems, and when the audience is very interested in the work, the words "become nailed", "heart-beating", "breathtaking", etc. As shown by, the unconscious movement of the body (hereinafter referred to as body movement) is temporarily stopped, and a large change appears in the heartbeat and respiration. Therefore, by detecting a biological signal such as a natural body movement, heartbeat, or respiration while the audience is watching the work, and displaying the result, the degree of interest in the work of the audience is objectively calculated and displayed. Then, by knowing the degree of this interest, it will be used as a reference for future work production, and the sales of new movies and videos will be predicted in advance,
The purpose is to help businesses to rationalize the scale of sales of works and advance advertising methods.

[0005]

In order to achieve the above object, the present invention provides a body movement detecting means installed in a seat for detecting body movement of the body of an occupant, and a body obtained from the body movement detecting means. First signal processing means for processing a moving signal, at least one biological signal detecting means for detecting a biological signal of the occupant, and second for processing a biological signal obtained from the biological signal detecting means. A signal processing means, a computing means, and a display means are provided.

[0006]

According to the present invention, the body movement detecting means installed in the seat detects the body movement of the seated person who is viewing the work.
The body movement signal obtained from the body movement detecting means is processed by the first signal processing means. Further, the biological signal other than the body movement of the occupant is detected by the biological signal detecting means, and the signal processing is performed by the second signal processing means. The calculation means performs various calculations on these processed signals and displays the results on the display means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a seat installed in a facility such as a movie theater or a theater, and a body motion detecting means 4 is provided between a cushion material (not shown) in a seat surface 2 and a cover 3. It is provided. Further, in order to easily detect biological signals such as heartbeat and respiration, a cushion material (not shown) in the backrest portion 5 of the seat 1, which is a position close to the heart and lungs of the human body, and a cover fabric 6 of the backrest portion. The biological signal detection means 7 is installed between them. The body movement detecting means 4 and the biological signal detecting means 7 are electrically connected to a control box 8 installed below the seat surface 2 in order to process the obtained signals.

Next, the structures of the body movement detecting means 4, the biological signal detecting means 7 and the control box 8 will be described with reference to FIG. In the figure, the body movement detecting means 4 and the biological signal detecting means 7 are composed of piezoelectric elements. A polymer piezoelectric material such as polyvinylidene fluoride (PVDF) is formed into a thin film, and flexible electrode films are formed on both sides. It is a tape-shaped product to which is adhered. The control box 8 contains a first signal processing means 9 and a second signal processing means 10. The first signal processing means 9 responds to the body movement signal from the body movement detecting means 4 by 4-5 Hz generated by the body movement.
Low-pass filter 11, first amplifier 12, first integrator 13, first A
It has a D converter 14. The second signal processing means 10 allows the second low-pass filter 15 to pass only a low frequency component of about 1 Hz with respect to the signal generated from the biological signal detecting means 7 with respect to the biological signal such as heartbeat or respiration. Amplifier 16, second integrator 17, second AD converter 18
Have. The control box 8 including these is the computing means 1
9, connected to the display means 20.

In the above structure, when a human body is present on the seat 1, the body movement detecting means 4 and the biological signal detecting means 7 are provided.
Is deformed by body movements such as limb movements of the human body and heartbeats and respirations, and a minute voltage is generated by the piezoelectric effect. Then, only a predetermined frequency component of the generated voltage output passes through the first or second low-pass filter 11 or 15 in the control box 4, and the amplifier 12 or 1
After being amplified by 6, it is integrated by the integrator 13 or 17.

An example of a general output signal after passing through the integrator 13 or 17 is shown in FIG. As shown in FIG. 3 (A), a large output occurs when a human body makes a large body movement such as sitting on or leaving the seat 1. Also,
In the case of body movement such as limb movement, as shown in (B), a level output corresponding to the magnitude of the movement is obtained. On the other hand, in the stationary state, as shown in (C),
Low level output based on the human body's heartbeat and respiration continues. This low-level output signal is mainly obtained from the biological signal detecting means 7 installed in the backrest part 5. If the human body is not present in the seat 1, the signal output is 0 as shown in (D). Calculation means 1 for these signal patterns
If the threshold value V is set in FIG. 9 as shown in FIG. 3, when a signal equal to or higher than V is obtained, it means that a large body movement such as a movement of a trunk or a limb is occurring. If it is V or less, the motion of the body is stationary, and a small body motion based on heartbeat and respiration occurs. Then, these body movement signals from the body movement detecting means 4 are converted into digital amounts by the AD converters 14 or 18 according to their respective magnitudes, calculated as body movement amounts by the calculating means 19, and displayed on the display means 20. It

In contrast to the above basic body movement pattern, the body movements of the audience seated in the seat 1 and viewing the work are observed in various ways. As shown in FIG. 4 by the time T, when the work is boring or uninteresting for the audience, body movements due to body movements frequently occur, A large output equal to or higher than the threshold value V is obtained from the body movement detecting means installed on the seat surface 2. On the other hand, since the mental state is not the excited state, the biological signal detecting means 7 can obtain a stable heartbeat or respiration waveform. However, when the work reaches a state that attracts the audience, such as after the time T, the body motion is stopped, and therefore the body motion detection means 4
The output from is continuing at a small value below V. Then, the biological signal detecting means 7 obtains a waveform indicating that the heart rate is rising or the breathing is disturbed. Therefore, by calculating these signals by the calculation means 19 and displaying them on the display means 20, it is possible to evaluate which part of the work the viewer is interested in and how much. In addition, the calculation means 19 accumulates the body motion stillness in which the threshold value of the body motion is V or less over the entire time during the viewing of the work, the accumulated time in which the heart rate is increased, or the accumulated time in which the breathing is disturbed. By calculating and comparing various works, it is possible to objectively know whether the work was interesting to the audience.

In the embodiment, the calculation means 19 and the display means 2
Although 0 is connected by wire to indicate the calculation result, the body movement detecting means 4, the biological signal detecting means 7, the control box 4 and the calculating means are installed in a theater or a movie theater in various places, and a wireless communication means ( It is also possible to evaluate the work in real time by using (not shown) to communicate the calculation result to the display means 20 installed in a collection center or the like.
