DETAILED DESCRIPTION

The terms used in the embodiments are selected from among common terms that are currently widely used, in consideration of their function in the embodiments. However, the terms may become different according to an intention of one of ordinary skill in the art, a precedent, or the advent of new technology. Also, in particular cases, the terms are discretionally selected by the applicant of the disclosure, and the meaning of those terms will be described in detail in the corresponding part of the detailed description. Therefore, the terms used in the disclosure are not merely designations of the terms, but the terms are defined based on the meaning of the terms and content throughout the disclosure.

It will be understood that when a certain part “includes” a certain component, the part does not exclude another component but may further include another component, unless the context clearly dictates otherwise. Also, terms such as “unit,” “module,” etc., as used in the specification may refer to a part for processing at least one function or operation and may be implemented as hardware, software, or a combination of hardware and software.

For example, expressions “at least one of a, b, or c” and “at least one of a, b, and c” should be construed as referring to “a,” “b,” “c,” “a and b,” “a and c,” “b and c,” or “a, b, and c.”

FIG. 1 is a diagram illustrating a wearable device 100 according to an embodiment, and FIG. 2 is a diagram schematically illustrating a use state of the wearable device 100 according to an embodiment.

Referring to FIGS. 1 and 2, the wearable device 100 may provide a smoking effect, and the wearable device 100 may include a first stimulus member 111, a second stimulus member 112, a link 113, and a controller.

The first stimulus member 111 may be disposed on a position corresponding to a first region of a user to provide electrical stimulation. The first region may be a posterior (e.g., the side in the −X direction of FIG. 2) of an auricle of an ear (e.g., a right ear ER of FIG. 2) of the user.

The first stimulus member 111 may include an electrode that performs electrical stimulation. The electrode may be connected to a power supply and the controller accommodated in the wearable device 100.

The second stimulus member 112 may be disposition in a position corresponding to a second region of the user to provide sound stimulation. The second region may be the auricle or a surface of an external auditory canal of the ear of the user.

For example, the second stimulus member 112 may include an earpiece. The earpiece may be a device capable of receiving sound data from the wearable device 100 and may include a device that may be worn on the ear of the user and that may receive sound data, such as an earbud, an earphone, hearing electronics, and the like.

The link 113 may connect the first stimulus member 111 to the second stimulus member 112 and may be configured to be hooked to the auricle of the user.

The link 113 of the wearable device 100 may be worn on the body of the user (e.g., the right ear ER of FIG. 2) with the first stimulus member 111 and the second stimulus member 112 in contact with the first region and the second region of the user, respectively. The link 113 may be made of metal or plastic material. A portion of the link 113 (e.g., an edge) may be made of metal material and the other portion of the link 113 may be made of plastic material.

The wearable device 100 may have a button B on an outside, and operations of the wearable device 100 may be controlled through the button B. For example, when the operation of the wearable device 100 is initiated, brain stimulation may be performed for a preset period of time. After the preset period of time, the brain stimulation may be stopped and a notification may be sent to the user indicating the brain stimulation has stopped.

An internal space of the wearable device 100 may additionally accommodate a memory, a communication unit, and the like.

For example, the memory may be hardware for storing various pieces of data that are processed in the wearable device 100 and may store data that has been processed by the controller and data to be processed by the controller. The memory may include at least one type of storage medium of flash memory-type memory, hard disk-type memory, multimedia card micro-type memory, card-type memory (e.g., a secure digital (SD) or extreme digital (XD) memory), random-access memory (RAM), static random-access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, a magnetic disk, or an optical disk. The memory may store an operating time, a maximum use time, and a current use time of the wearable device 100, and data on a smoking pattern of the user.

For example, the communication unit may include a short-range wireless communication unit and a wireless communication unit. The short-range wireless communication unit may include a Bluetooth communication unit, a Bluetooth Low Energy (BLE) communication unit, a near field communication unit, a wireless local area network (WLAN) (e.g., wireless fidelity (Wi-Fi)) communication unit, a ZigBee communication unit, an infrared data association (IrDA) communication unit, a Wi-Fi direct (WFD) communication unit, an ultra-wideband (UWB) communication unit, an Ant+ communication unit, and the like. However, embodiments are not limited thereto. The wireless communication unit may include a cellular network communication unit, an Internet communication unit, a computer network (e.g., a local area network (LAN) or a wide-area network (WAN)) communication unit, and the like. However, embodiments are not limited thereto.

The controller of the wearable device 100 may control the first stimulus member 111 and/or the second stimulus member 112 so that the first stimulus member 111 and/or the second stimulus member 112 may generate a stimulus signal that induces a state of alertness that may implement a smoking effect. For example, the controller may be accommodated in the internal space of the wearable device 100 and connected to the first stimulus member 111 and/or the second stimulus member 112. In another example, the controller may be accommodated in another electronic device (e.g., a mobile communication terminal) outside of the wearable device 100 and may provide a control signal to the first stimulus member 111 and/or the second stimulus member 112 through the communication unit.

The first stimulus member 111 and/or the second stimulus member 112 may generate the stimulus signal that may stimulate the brain of the user. For example, the stimulus signal may include electrical stimulation and/or sound stimulation.

The controller of wearable device 100 may control the first stimulus member 111 and/or the second stimulus member 112 to provide a brain stimulus signal that may increase a beta waves region of electroencephalogram (EEG) of the user. The first stimulus member 111 and/or the second stimulus member 112 may provide the stimulus signal (e.g., a stimulus signal that may increase beta waves of the EEG of the user) that induces a state of alertness that may implement a smoking effect.

A frequency range of delta waves may be from 1 Hz to 4 Hz, and delta waves are associated with an involuntary physical activity, such as the heartbeat and digestion. When power associated with delta waves is increased, a state of rest and sleep may be induced in a user O and a situation such as relaxation may be implemented. On the contrary, when the power associated with delta waves is decreased, a state of alertness may be induced. A frequency range of theta waves may be from 4 Hz to 8 Hz, and theta waves may mainly occur during meditation or when a hippocampus is activated. The hippocampus may be a region that controls a memory. When power associated with theta waves is increased, a state of inspiration, insight, or connecting pieces of memory may be induced. On the contrary, when the power associated with theta waves is decreased, a state of anxiety, stress, and low emotional self-awareness may be induced. A frequency range of beta waves may be from 12 Hz to 25 Hz, and since beta waves normally occur during alertness, an increase in beta waves may indicate alertness. When power associated with beta waves is increased, a state of alertness such as a situation of cognitive thought activity may be induced. On the contrary, when the power associated with beta waves are decreased, a state of relaxation may be induced.

FIG. 3 is a diagram illustrating EEG of a user before and after smoking a cigarette or an electronic cigarette (e-cigarette), and FIG. 4 is a diagram illustrating EEG of a user before and after stimulation by the wearable device 100 or a system for providing a smoking effect.

Referring to FIG. 3, the graph in FIG. 3 shows a measurement of the EEG of a subject before and after smoking a cigarette or an e-cigarette, and an electrophysiological method of recording electrical activity of a brain through an electrode was used. The detailed method of the experiment is as follows. EEG sensors (i.e., sensors for measuring EEG) were attached to a plurality of positions on the heads of subjects. The subjects were divided into two groups, a cigarette group and an e-cigarette group, and EEG was measured before and after smoking in each of the cases. Results of analysis of power spectral density (PSD) before and after smoking are shown in the graph of FIG. 3. Referring to FIG. 3, as a result of analysis of pieces of power of all bands, it is confirmed that the low-frequency (e.g., delta waves and theta waves) range tends to decrease and the high-frequency (e.g., beta waves) range tends to increase after smoking. For example, it is confirmed that PSD of the EEG of the user in a frequency range of 10 Hz or higher tends to increase in general.

Referring to FIG. 4, a same or similar result as actual smoking shown in FIG. 3 was implemented using the wearable device 100 by configuring the first stimulus member 111 and/or the second stimulus member 112 to perform brain stimulation such as electrical stimulation and/or sound stimulation so that the low-frequency range of the EEG of a user may decrease and the high-frequency range of the EEG of the user may increase after the brain stimulation.

As shown in FIG. 4, electrical stimulation and/or sound stimulation by the wearable device 100 may implement an actual smoking effect by changing the power of the EEG band (e.g., increasing the power of beta waves).

In addition, electrical stimulation from the first stimulus member 111 may be transcranial alternating current stimulation (tACS), and the tACS may affect a change in periodic excitability of a neuron in a cerebral cortex with a maximum current within 2 mA of a sine waveform at various frequencies and may induce a change in a brain function such as cognition and memory. An applied frequency may be 10 Hz, and a stimulation time may be 10 to 30 minutes.

Sound stimulation from the second stimulus member 120 may induce beta waves stimulation of the EEG of the user by utilizing a binaural beat. The binaural beat may send different frequency signals to the ears of the user so that the brain may perceive a difference between the two frequencies. Here, the difference between the two frequencies may be 12 Hz to 25 Hz, which corresponds to beta waves.

The controller of the wearable device 100 may control the first stimulus member 111 and/or the second stimulus member 112 so that the first stimulus member 111 and/or the second stimulus member 112 may provide a brain stimulus signal that may increase the frequency of an EEG region of the user corresponding to 10 Hz or higher.

The controller of the wearable device 100 may control the first stimulus member 111 so that the first stimulus member 111 may provide electrical stimulation that may cause the PSD of the EEG of the user to increase by 0.1 to 1.1 dB in a frequency range of 12 Hz to 25 Hz.

In addition, the controller of the wearable device 100 may control the first stimulus member 111 so that the first stimulus member 111 may provide electrical stimulation that may cause the PSD of the EEG of the user to decrease by 0.3 to 0.9 dB in a frequency range of 1 Hz to 4 Hz. Furthermore, the controller of the wearable device 100 may control the first stimulus member 111 so that the first stimulus member 111 may provide electrical stimulation that may cause the PSD of the EEG of the user to decrease by 0.2 to 0.5 dB in a frequency range of 4 Hz to 8 Hz.

The controller of the wearable device 100 may control the second stimulus member 112 so that the second stimulus member 112 may provide sound stimulation that may cause the PSD of the EEG of the user to increase by 0.1 to 1.1 dB in a frequency range of 12 Hz to 25 Hz.

The controller of the wearable device 100 may simultaneously control the first stimulus member 111 and the second stimulus member 112 so that the first stimulus member 111 and the second stimulus member 112 may cause the PSD of the EEG of the user to increase by 0.1 to 1.1 dB in a frequency range of 12 Hz to 25 Hz.

The controller of the wearable device 100 may determine whether to perform brain stimulation using the first stimulus member 111, perform brain stimulation using the second stimulus member 112, or perform brain stimulation using both of the first stimulus member 111 and the second stimulus member 112, depending on a surrounding environment or a state of the user.

For example, when a sound noise around the wearable device 100 is greater than or equal to a set value, the controller of the wearable device 100 may provide a smoking effect to the user by performing brain stimulation by electrical stimulation through the first stimulus member 111 instead of the second stimulus member 112.

In another example, when an area around the wearable device 100 is in a state of over-humidity such as in a rainy season or when sweat is detected on a skin of the user above the set value, the controller of the wearable device 100 may determine that the condition is unfavorable to electrical stimulation and may provide a smoking effect to the user by performing brain stimulation by sound stimulation through the second stimulus member 112.

In another example, when an increased smoking effect needs to be provided in a short period of time, the controller of the wearable device 100 may simultaneously operate the first stimulus member 111 and the second stimulus member 112 to perform rapid and intense brain stimulation.

The wearable device 100 may further include a verification member that verifies a smoking effect. The verification member may measure a heart rate variability (HRV).

An HRV may refer to a comprehensive combination of indicators, such as a heart rate (HR), a mean interval between electrocardiogram (ECG) peaks (mean R-R interval), a standard deviation of normal to normal R-R intervals (SDNN), which indicates stress resistance (physiological resilience), a root mean square of successive heartbeat interval differences (RMSSD), which is a parasympathetic index that is involved in electrical stability of the heart, low frequency (LF), which is a relatively low-frequency component and an indicator of a sympathetic nervous activity, high frequency (HF), which is a relatively high-frequency component and related to a respiratory activity, and the like. A healthier person may have a complex HRV. Here, an increase in an HR may indicate an excitement and an increase in load (physical activity), a decrease in an SDNN may indicate a monotonous HR fluctuation signal, a decrease in an ability to cope with stress, and a decrease in overall health, a decrease in an RMSSD may indicate a heart abnormality, and an increase in an LF may indicate a decrease in an HRV.

FIGS. 5A to 5E are diagrams illustrating indicators of an HRV of a user before and after smoking a cigarette or an e-cigarette. In the case of an e-cigarette, effects of an e-cigarette containing nicotine on ECG indicators before and after smoking are shown. FIG. 5A illustrates a mean HR, FIG. 5B illustrates an RMSSD, FIG. 5C illustrates an SDNN, FIG. 5D illustrates an LF band, and FIG. 5E illustrates an HF band. Referring to FIGS. 5A to 5E, the mean HR and the LF band increased, while the SDNN, the RMSSD, and the HF band decreased. This may indicate a physiological and psychological state similar to an alertness in response to stimulation.

FIGS. 6A and 6B are diagrams illustrating a change in HRV indicators (e.g., an autonomic balance) caused by electrical stimulation through the wearable device 100. FIG. 6A illustrates the autonomic balance before the electrical stimulation and FIG. 6B illustrates the autonomic balance after the electrical stimulation. As shown in FIGS. 6A and 6B, it may be confirmed that the autonomic balance improves after the electrical stimulation compared to before the electrical stimulation. This may indicate a physiological and psychological state similar to an alertness in response to stimulation.

The alertness effect after stimulation (providing a smoking effect) by the wearable device 100 may be confirmed through a verification member. For example, the verification member may utilize an SDNN or an RMSSD among the HRV indicators to confirm a decrease in the SDNN or the RMSSD and/or a degree of decrease in the SDNN and the RMSSD before and after the stimulation and may thus verify whether a sufficient alertness effect (i.e., a smoking effect) has been achieved.

The controller of the wearable device 100 may determine a degree of activation of the first stimulus member 111 and/or the second stimulus member 112 based on a smoking indicator (e.g., the HRV indicators) signal transmitted from the verification member. For example, when a degree of decrease in the SDNN or the RMSSD confirmed by the verification member is sufficient enough to be equivalent to a prestored degree of decrease in the SDNN or the RMSSD in actual smoking, the controller may maintain a control state of the first stimulus member 111 and/or the second stimulus member 112. On the contrary, when a degree of decrease in the SDNN or the RMSSD confirmed by the verification member is not sufficient enough to be equivalent to the prestored degree of decrease in the SDNN or the RMSSD in actual smoking, the controller may increase or decrease a stimulation intensity of the first stimulus member 111 and/or the second stimulus member 112.

FIG. 7 is a diagram illustrating a system for providing a smoking effect. The system for providing a smoking effect may include a first wearable device 110 (e.g., the wearable device 100 of FIG. 1) that may be worn on the right ear ER of the user O and a second wearable device 120 that may be worn on a left ear EL of the user O.

The first wearable device 110 may include a first stimulus member (e.g., the first stimulus member 111 of FIG. 1) disposed at the rear of the right ear ER to provide electrical stimulation and a second stimulus member (e.g., the second stimulus member 112 of FIG. 112) disposed on an auricle or a surface of an external auditory canal of the right ear ER to provide first sound stimulation.

The second wearable device 120 may include a third stimulus member disposed at the rear of the left ear EL to provide electrical stimulation and a fourth stimulation member disposed on an auricle or a surface of an external auditory canal of the left ear EL to provide second sound stimulation. Since the third stimulus member may be configured to be identical or similar to the first stimulus member 111 and the fourth stimulus member may be configured to be identical or similar to the second stimulus member 112, a detailed description of the third stimulus member and the fourth stimulus member is omitted herein for simplicity. At least one of the first stimulus member 111, the second stimulus member 112, the third stimulus member, or the fourth stimulus member may provide a stimulus signal that may implement a smoking effect.

For example, a controller of the first wearable device 110 may control the first stimulus member 111 and the second stimulus member 112, and a controller of the second wearable device 120 may control the third stimulus member and the fourth stimulus member. In this case, the controller of the first wearable device 110 and the controller of the second wearable device 120 may be synchronized with each other. Alternatively, a controller may be provided on one of the first wearable device 110 or the second wearable device 120, wherein the controller may control all of the first stimulus member 111, the second stimulus member 112, the third stimulus member, and the fourth stimulus member.

The first stimulus member 111 and the third stimulus member may provide electrical stimulation to the rear of the ear of the user. For example, the first stimulus member 111 may include an anode (+), and the third stimulus member may include a cathode (−). The controller may cause an electric current to flow from the anode of the first stimulus member 111 to the cathode of the third stimulus member and to flow from the rear of the right ear ER of the user O through the brain of the user O to the rear of the left ear EL of the user O. Here, an excitability of neurons in the cortex of the brain adjacent to the first stimulus member 111 may increase and an excitability of neurons in the cortex of the brain adjacent to the third stimulus member may decrease so that an alertness effect of the user may be maximized.

The controller may provide an alertness effect to the user O by causing the second stimulus member 112 of the first wearable device 110 and the fourth stimulus member of the second wearable device 120 to form a binaural beat that provides beta waves. For example, the controller may adjust EEG according to a frequency difference of music or white noise injected into both ears of the user and create beta waves that may provide an alertness effect to the user O.

For example, the controller may cause a difference between a frequency of sound stimulation of the second stimulus member 112 of the first wearable device 110 and a frequency of sound stimulation of the fourth stimulus member of the second wearable device 120 to be from 12 to 25 Hz.

According to the wearable devices 110 and 120 and the system 10 for providing a smoking effect, a smoking effect may be provided to the user O without an act of smoking. In this case, a smoking effect may effectively be provided through stimulation of the brain of the user O. The wearable devices 110 and 120 and the system 10 for providing a smoking effect may selectively and/or simultaneously perform brain stimulation by electrical stimulation or brain stimulation by sound stimulation to allow brain stimulation optimized for a use environment. As the wearable devices 110 and 120 and the system 10 for providing a smoking effect may adjust a degree of stimulus activation based on feedback (e.g., the HRV of the user) from the user, the degree of brain stimulation may effectively be controlled.

The descriptions of the above-described embodiments are only examples, and it will be understood by one of ordinary skill in the art that various changes and equivalents may be made therefrom. Therefore, the scope of the disclosure should be defined by the appended claims, and all differences within the scope equivalent to those described in the claims will be construed as being included in the scope of protection defined by the claims.
