Description

[Technical Field]

[0001] The present invention relates to a body temperature measuring device for measuring the temperature of a subject's face. [Background technology]

[0002] It is known that when a user experiences physical changes due to emotional movements, autonomic nervous activity causes vasoconstriction and dilation, resulting in changes in blood flow. For example, when a person is experiencing pleasant emotions, the activity of the sympathetic nervous system weakens while the activity of the parasympathetic nervous system strengthens, causing blood flow in the blood vessels to speed up and blood flow to increase. In contrast, when a person is experiencing unpleasant emotions, the activity of the sympathetic nervous system strengthens while the activity of the parasympathetic nervous system weakens, causing blood flow in the blood vessels to slow down and blood flow to decrease.

[0003] When blood flow increases, skin temperature rises, and when blood flow decreases, skin temperature drops. In particular, in the nose, where blood vessels pass through the small gap between the skin and the nasal bone, skin temperature is easily affected by changes in blood flow. Therefore, there have been many reports that acquiring a user's nose temperature is useful for estimating the user's emotions. Continuously measuring a user's nose temperature on a daily basis is expected to create a database for estimating the user's emotions (Non-Patent Document 1, Non-Patent Document 2, Non-Patent Document 3).

[Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a perspective view showing a partial configuration of a body temperature measuring device according to an embodiment of the present invention. [Figure 2] FIG. 2 is a diagram showing a partial configuration of the body temperature measuring device according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] A body temperature measuring device according to an embodiment of the present invention will be described below with reference to Figures 1 and 2. This body temperature measuring device includes a holding mechanism 121, a first temperature sensor 101a, a second temperature sensor 101b, a third temperature sensor 102, a fourth temperature sensor 103, a fifth temperature sensor 104a, and a sixth temperature sensor 104b.

[0011] The holding mechanism 121 is attached to the subject. The first temperature sensor 101a and the second temperature sensor 101b are provided on the holding mechanism 121 and measure the temperatures (skin surface temperatures) of the left and right sides of the bridge of the subject's nose. For example, the first temperature sensor 101a measures the temperature of the right side of the bridge of the subject's nose. The second temperature sensor 101b measures the temperature of the left side of the bridge of the subject's nose.

[0012] The third temperature sensor 102 is provided in the holding mechanism 121 and measures the temperature (skin surface temperature) of the tip of the nose of the person being measured. The fourth temperature sensor 103 is provided in the holding mechanism 121 and measures the temperature (skin surface temperature) between the eyebrows of the person being measured.

[0013] The fifth temperature sensor 104a and the sixth temperature sensor 104b are provided in the holding mechanism 121 and measure the temperatures (skin surface temperatures) behind the left and right ear helices of the subject. For example, the fifth temperature sensor 104a measures the temperature behind the right ear helix of the subject. For example, the sixth temperature sensor 104b measures the temperature behind the left ear helix of the subject.

[0014] This body temperature measuring device also includes a processing circuit 105, a transmission circuit 106, and a power supply circuit 107. The processing circuit 105 acquires measurements taken by the first temperature sensor 101a, the second temperature sensor 101b, the third temperature sensor 102, the fourth temperature sensor 103, the fifth temperature sensor 104a, and the sixth temperature sensor 104b. The transmission circuit 106 transmits the measurement values acquired by the processing circuit 105 to a preset destination in accordance with a preset format. The transmission circuit 106 transmits the measurement values to an external device, such as a smartphone, tablet terminal, or personal computer, as the destination, via wireless communication such as Bluetooth (registered trademark) or a wireless LAN (Local Area Network) or by wired communication.

[0015] The power supply circuit 107 supplies power to the first temperature sensor 101a, the second temperature sensor 101b, the third temperature sensor 102, the fourth temperature sensor 103, the fifth temperature sensor 104a, the sixth temperature sensor 104b, the processing circuit 105, and the transmission circuit 106. The processing circuit 105, the transmission circuit 106, and the power supply circuit 107 can be built into the holding mechanism 121.

[0016] The processing circuit 105 and the transmission circuit 106 can be configured from a computer device equipped with a CPU, a main storage device, an external storage device, a network connection, etc. Each function can be realized by the CPU operating according to a program loaded in the main storage device.

[0017] For example, the holding mechanism 121 can be an eyeglass frame worn by the subject. The first temperature sensor 101a and the second temperature sensor 101b are provided on pads 122a and 122b of the eyeglass frame, respectively, and measure the skin temperature of the subject facing the pads 122a and 122b.

[0018] The third temperature sensor 102 is provided at the tip of a support rod 131 that extends downward from the bridge 123 of the eyeglass frame, and measures the skin temperature of the person being measured at the tip of the support rod 131. The fourth temperature sensor 103 is provided on the bridge 123, and measures the skin temperature of the person being measured that the bridge 123 faces.

[0019] The fifth temperature sensor 104a and the sixth temperature sensor 104b are provided on both end pieces 124a and 124b of the eyeglass frame, respectively, and measure the skin temperature of the person to be measured, where the end pieces 124a and 124b face each other.

[0020] In addition, the first temperature sensor 101a, the second temperature sensor 101b, the third temperature sensor 102, the fifth temperature sensor 104a, and the sixth temperature sensor 104b are used in contact with the skin of the person being measured and can be composed of thermocouples, and the fourth temperature sensor 103 can be composed of an infrared sensor (thermopile).

[0021] Of course, the individual temperature measurement results from the first temperature sensor 101a, second temperature sensor 101b, third temperature sensor 102, fourth temperature sensor 103, fifth temperature sensor 104a, and sixth temperature sensor 104b are useful, but by combining these, it is possible to obtain signals related to emotions and physiological states, such as changes in the autonomic nervous system that controls the left brain by obtaining temperature changes at the root and tip of the left nose, and changes in the autonomic nervous system that controls the right brain by obtaining temperature changes at the root and tip of the right nose.

[0022] For example, it is possible to obtain (estimate) changes in the autonomic nervous system that controls the left brain from temperature changes at the root and tip of the left nose. Also, it is possible to obtain (estimate) changes in the autonomic nervous system that controls the right brain from temperature changes at the root and tip of the right nose. Also, it is possible to obtain (estimate) changes in the autonomic nervous system that controls the left-right center from temperature changes between the eyebrows and the tip of the nose. From asymmetric temperature changes and temperature gradients, it is possible to determine whether an individual is intuitive or logically emotionally dominant.

[0023] The holding mechanism 121 is not limited to an eyeglass frame, and can be, for example, a face shield worn by the subject. In this case, the subject can continuously obtain body temperature data in their daily lives while wearing the face shield, which is effective in preventing infection.

[0024] Furthermore, the holding mechanism 121 can be goggles (for example, VR goggles) worn by the subject. In this case, continuous changes in body temperature can be fed back into the virtual reality, which can improve the sense of reality and unity of the virtual reality.

[0025] As described above, according to the present invention, the holding mechanism attached to the person being measured is provided with a first temperature sensor, a second temperature sensor, a third temperature sensor, a fourth temperature sensor, a fifth temperature sensor, and a sixth temperature sensor, so that the temperature of the face, including the nose, can be measured easily and continuously without disrupting the person's daily life.
