Description

The present invention relates to a seating device that objectively predicts how interesting a content of a work such as a movie or a video is to a viewer before the work is released.

When launching a new movie or video, operators want to know objectively what parts of these works are interesting to the audience and whether the whole work is of interest. This is because, if you know this in advance, it will be a good reference for future work production, as well as the scale of release of the work and the way of advertising in advance. For this reason, in the past, there have been methods of following works that have been well received in the past, and holding previews in advance to hear the reputation of the works.

However, recently, the tastes of the audience have been diversified, and it has become difficult for the business operator to grasp what kind of work gets a good reputation by the above-mentioned conventional method. In other words, even if a movie or video production expert follows a work that has been well received in the past, it often fails because the audience has already been rejected. In addition, there was a problem that it was difficult to obtain an objective evaluation such as which part was interesting even if a preview was held and the reputation of the new work was heard in advance.

The present invention solves the above-mentioned problem, and when the audience is very interested in the work, as the words such as "become caught", "pounding chest", "hold breath" etc. In addition, unconscious movement of the body (hereinafter referred to as body movement) temporarily stops, and a large change in heartbeat and breathing appears. Therefore, by detecting a natural signal such as a physical movement or a heartbeat or breathing while watching the work of the spectator, the degree of interest in the spectator's work is objectively calculated and displayed by displaying the result. By knowing this degree of interest, it can be used as a reference for future work production and predicting the sales of new movies and videos in advance, and the business can rationalize the scale of release of works and the way of advertising in advance. It is intended to provide support for doing so.

In order to achieve the above object, the present invention provides a body movement detecting means which is installed on a seat where a work such as a movie or a video can be watched and detects a body movement based on a body movement of a occupant who is watching the work; At least one biological signal detecting means for detecting a biological signal due to a small body movement such as a heartbeat or breathing of the occupant who is installed in the work and watching the work, and an output signal of the body movement detecting means and the biological signal detecting means. Display means capable of displaying a body motion signal, a heartbeat signal, and a breathing signal of the occupant who is watching the work based on which part of the work the occupant was interested in based on the display information of the display means. Can be evaluated.

明 ら か As is clear from the above description, according to the seated device of the present invention, the following effects can be obtained.

Body motion detection means installed on a seat that can appreciate works such as movies and videos, and biological signal detection means to detect the body movement and biosignal of the audience while watching the work, and calculate the amount of body motion and biosignal Means and display means for displaying the calculation results,
(1) It is possible to know which part of the work the audience was interested in, and this can be used as a reference for future productions for film and video creators.

(2) It is possible to know the degree of interest of the audience over the entire time of viewing the work, and it is possible for the business operator to reasonably sell the work and advertise it.

According to the present invention, with the above-described configuration, the body movement detecting means installed on the seat detects the body movement of the occupant who is watching the work. Further, a small body movement such as a heartbeat or breathing of the occupant is detected by the biological signal detecting means while the work is being watched. By displaying the detected body motion signal, heartbeat signal, and respiration signal by the display means, it is possible to evaluate which part of the work the interested person was interested in, based on the signal.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a seat installed in a facility such as a movie theater or a theater, and a body movement detecting means 4 is provided between a cushion material (not shown) in a seat surface 2 and a top cloth 3. I have. In addition, a cushion (not shown) in the backrest portion 5 of the seat 1 and a surface cloth 6 of the backrest portion are located near the heart and lungs of the human body so as to easily detect biological signals such as heartbeat and breathing. Between them, a biological signal detecting means 7 is provided. The body movement detecting means 4 and the biological signal detecting means 7 are each electrically connected to a control box 8 installed below the seating surface 2 for processing the obtained signals.

Next, the configurations 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, a body movement detecting means 4 and a biological signal detecting means 7 are constituted by piezoelectric elements, and a polymer piezoelectric material such as polyvinylidene fluoride (PVDF) is formed into a thin film, and flexible electrode films are formed on both surfaces. Is formed into a tape shape. The control box 8 has a first signal processing means 9 and a second signal processing means 10 built therein. The first signal processing unit 9 includes a first low-pass filter 11, a first amplifier 12, and a first low-pass filter 11 that pass only a frequency component of 4 to 5 Hz generated by the body motion with respect to the body motion signal from the body motion detection unit 4. It has a first integrator 13 and a first AD converter 14. The second signal processing unit 10 includes a second low-pass filter 15 that allows only a low frequency component of about 1 Hz to pass through a signal generated from the biological signal detecting unit 7 with respect to a biological signal such as a heartbeat or respiration, It has an amplifier 16, a second integrator 17, and a second AD converter 18. The control box 8 including these is connected to the calculation means 19 and the display means 20.

In the above configuration, when a human body is present on the seat 1, the body movement detecting means 4 and the biological signal detecting means 7 are deformed by the movement of the limbs of the human body and body movements such as heartbeat and breathing, and are caused by the piezoelectric effect. A very small voltage is generated. 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 is amplified by the amplifier 12 or 16 and then the integrator 13 or 17 Is integrated by

FIG. 3 shows an example of a general output signal after passing through the integrator 13 or 17. As shown in FIG. 3A, a large output is generated when the human body performs a large body motion such as taking a seat on or leaving the seat 1. In the case of a body movement such as a limb movement, an output of a level corresponding to the magnitude of the movement is obtained as shown in FIG. On the other hand, in the stationary state, as shown in (C), a low-level output based on the heartbeat and respiration of the human body continues. This low level output signal is obtained mainly from the biological signal detecting means 7 installed in the backrest portion 5. If the human body is absent from the seat 1, the signal output becomes 0 as shown in (D). If a threshold value V is set in the arithmetic means 19 for these signal patterns as shown in FIG. 3, when a signal of V or more is obtained, large body movement such as movement of the trunk or limbs occurs. Will be. If it is equal to or less than V, the motion of the body is stationary, and a small body motion based on the heartbeat / respiration occurs. These body movement signals from the body movement detecting means 4 are converted into digital quantities by the AD converters 14 or 18 according to their magnitudes, calculated by the arithmetic means 19 as body movement quantities, and displayed on the display means 20. You.

に 対 し In contrast to the basic body movement pattern described above, the body movements of the audience while sitting on the seat 1 and watching the work are observed in various forms. In FIG. 4, if the work is boring or uninteresting to the audience, as seen before time T, body movement due to body movement frequently occurs, A large output equal to or larger than the threshold value V is obtained from the body movement detecting means provided on the seat surface 2. On the other hand, since the mental state is not an excitable state, a stable heartbeat or breathing waveform is obtained from the biological signal detecting means 7. However, if the work reaches the audience, as shown after time T, the body motion stops, and the output from the body motion detecting means 4 continues to be a small value of V or less. Then, a waveform indicating that the heart rate has risen or breathing has been disturbed is obtained from the biological signal detection means 7. Therefore, by calculating these signals by the calculating means 19 and displaying the signals 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 arithmetic means 19 calculates the accumulated time of the body motion stationary, the accumulated time of the increase of the heart rate, or the accumulated time of the disturbance in the breathing, in which the threshold value of the body motion is V or less over the entire time of viewing the work. By calculating and comparing various works, it is possible to objectively know whether or not the work was interesting to the audience.

In the embodiment, the calculation means 19 and the display means 20 are connected by wire to indicate the calculation result. However, the body movement detection means 4, the biological signal detection means 7, the control box 4 and the calculation means are connected to theaters and movies in various places. The work can be evaluated in real time by installing it in a museum or the like and communicating the calculation results to a display means 20 installed in a tallying center or the like using a wireless communication means (not shown).
