The EEG measurement device 710 may be a wearable device capable of being worn on the head of a user, which may be manufactured in the form of a headband. The EEG measurement device 710 may measure EEG of the user using a dry EEG measurement scheme. The EEG measurement device 710 may measure EEG using a first sensor 711 in contact with an ear area and a second sensor 712 in contact with a scalp (e.g., a forehead).
The EEG measurement device 710 may further include a microphone 713 for measuring a breathing rate and/or a breathing sound of the user. The breathing rate may be used to measure a health state of the user. The breathing sound may be used to determine a stress degree of a driver or diagnose an emotional state depending on a pattern analysis of a sound source. The EEG measurement device 710 may determine a stress degree and/or an emotional state of the driver based on the loudness and roughness of the breathing sound.
When the palm of the user is in contact with a sensor (or an electrode) installed on a handle portion, the haptic controller 720 may measure a heart rate (or a maximum heart rate) of the user. The heart rate may also be measured on the wrist or ear. The heart rate may be used to determine a stress degree of the user or diagnose an emotional state of the user.
The biometric signal measurement device 700 may develop emotional content of a smart healing concept based on a user's body information analysis technology. In other words, the biometric signal measurement device 700 may develop an immersion enhancement technology for analyzing EEG, a heart rate, a breathing sound, and/or the like of the user, determining whether cyber sickness occurs based on the analyzed result, and preventing cyber sickness.
A service platform server 100 of
The service platform server 100 may classify a natural sound pattern based on the result of analyzing the biometric signal. For example, when an EEG fluctuation width is large, when the heart rate is high, and the breathing rate has an over-breathing pattern, the service platform server 100 may classify the natural sound pattern into regular hitting sounds (e.g., the sound of rain, the sound of waves, the sound of mountain temple bells, or the sound of birds). When the EEG fluctuation width is small, when the heart rate is low, and the breathing rate has a stable breathing pattern, the service platform server 100 may classify the natural sound pattern into calm and tranquil sounds (e.g., the sound of the forest, the sound of the stream, the sound of the wind, or the sound of grass insects). The service platform server 100 may analyze a correlation between biometric information and a natural sound and may derive (or determine) an emotional concept. When the natural sound pattern is classified into the regular hitting sounds by analyzing the correlation between the biometric information and the natural sound, the service platform server 100 may determine an emotional concept as “stress mitigation”. When the natural sound pattern is classified into the calm and tranquil sounds by analyzing the correlation between the biometric information and the natural sound, the service platform server 100 may determine an emotional concept as “meditation”.
The embodiment is not limited to the case where the user state is determined using the biometric information in the present embodiment. An embodiment may be implemented to determine a user state using a user face expression recognition technology and/or a user voice interaction technology. The service platform server 100 may generate an emotional care sound based on a natural sound using a sound design tool. The natural sound may include white noise and pink noise. The white noise is noise in an electronic device due to electron free motion and has a uniform spectrum for a frequency. The white noise may be associated with regular hitting sound (s), such as the sound of rain, the sound of waves, the sound of mountain temple bells, and/or the sound of birds. Because of having a non-constant sound band width and a wide spectrum characteristic, the white noise may relieve stress and may improve mental stability and concentration. The pink noise is noise, which has the same amount of energy every octave and is used as a sound source for test, such as sound characteristic measurement. The pink noise is associated with calm and tranquil sounds, such as the sound of the forest, the sound of the stream, the sound of the wind, and/or the sound of grass insects. The pink noise helps to sleep in conjunction with an autonomous sensory meridian response (ASMR), which is a sound configured to stimulate the brain and induce psychological stability and is highly related to meditation which gives psychological stability.
The service platform server 100 may recommend an AI-based personalized healing sound in a virtual environment and/or a vehicle environment. The service platform server 100 may provide an emotional care sound based on white noise or an emotional care sound based on pink noise depending on a user state. The service platform server 100 may recommend the emotional care sound as a healing sound and may block ambient noise, which is not desired by the user to listen, by means of sound masking.
The service platform server 100 may develop sound masking emotion content by means of white noise and pink noise. The sound masking may block unwanted ambient noise by neutralizing sounds that the user does not want to hear or disturbing sounds. The service platform server 100 may provide a spatial sound technology based on mixed reality (MR) using the sound masking.
When providing a user (e.g., a driver) with the emotional care sound based on the white noise or the emotional care sound based on the pink noise, the service platform server 100 may apply a sound masking technology to a vehicle such that a passenger (e.g., a passenger who sits on a passenger seat or a rear seat) except for the user (e.g., the driver) does not feel the sound as annoying noise.
As an embodiment, the service platform server 100 may measure a sound level (or a noise level) using a sensor installed on a front upper end in the interior of the vehicle with regard to an operation mode (e.g., a normal mode and a sleep mode) of a seat and a situation where users ride in all of front seats and rear seats. The service platform server 100 may play a masking sound source based on the measured sound level. The service platform server 100 may output the played masking sound to the outside through a front mid-range speaker of the vehicle.
As another embodiment, the service platform server 100 may sense a sound (or a sound level or a noise level) using a sensor installed (or located) at a user's ear position. The service platform server 100 may play a masking sound source based on the sensed sound. The service platform server 100 may output the played masking sound through a speaker installed (or located) at the user's ear position.
