I. Project overview

The project relies on the scientific research achievements of top cognitive psychology experts at home and abroad, combined with the technology of artificial intelligence and Internet of Things expert teams, to develop innovative emotional technology products and comprehensively analyze emotions in multiple dimensions. The smart multi-mood bracelet has been introduced as a scientific research tool by Peking University, Zhejiang Normal University, Soochow University, Southeast University and other universities. At the same time, as a new tool and unique technology for psychological awareness and psychological screening, it is widely used in schools, enterprises, organs and communities. With the increase of people with anxiety and depression tendencies screened by intelligent multidimensional emotional bracelet, more and more hospitals have included intelligent multidimensional emotional bracelet in physical examination projects. Chengdu Mental Health Center, Zhejiang Mental Health Center, Beijing National Olympic Mental Hospital, Nanning Second Maternal and Child Health Hospital, Mentougou Maternal and Child Health Hospital, Guangzhou Shengquan Mental Health Institute, Good Mood Clinic, etc.

Second, the main product

Intelligent multi-dimensional emotional bracelet - a new tool for psychological awareness and psychological screening. Emotional assessment and early warning system to meet the needs of users self-testing, self-training, consultant observation, manager screening, global macro data and other use scenarios!

1. Scenario 1: Know yourself

Focusing on themselves to understand themselves, the multi-dimensional intelligent emotional bracelet reminds users to pay attention to their emotions and stress states, and has emotional explosive shock warning function and emotional regulation method learning and training function. A brief 5 to 6 minutes to understand their emotional stress state, it is recommended that you can be measured several times a day to pay attention to themselves, and according to the intelligent report training to adjust themselves.

2. Scene 2: Mood lamp

Focusing on observation, the intelligent multi-dimensional emotion bracelet is connected with the emotion lamp, the emotional state is presented through the color change of the light, and the emotion that can not be touched is seen through an intuitive way! It has become a new favorite of psychological counselors for observation in the process of psychological conversation.

3. Scenario 3: Group screening

Focus on group testing, group screening. As a new tool for efficient psychological screening and a unique technology in the country, the intelligent multi-dimensional emotional bracelet is widely used in the psychological screening evaluation of students, employees and residents. Participants only need to wear an emotional bracelet and complete the screening assessment in 20 minutes while attending class or working. The group report and individual report are automatically generated, and the manager can intuitively see the people needing attention and the existing problems. At present, the way to carry out the group assessment of emotional bracelet simultaneously in psychological lectures has also been welcomed and widely adopted by schools and units.

Third, the working principle of intelligent multi-dimensional emotional bracelet

Through photoelectric acquisition, various HRV (heart rate variability) indicators and pressure indicators are analyzed by observing the change characteristics of the interval between wave peaks. Emotional psychological state is analyzed by the comprehensive analysis model of emotional stress with a unique patent. According to the crisis warning model with a unique patent, people in need of attention are screened.

Popular understanding: electrocardiogram crest, how many in a minute, the heart rate is how much, if two people are 73, the heart rate is 73. But between the two peaks, one person is big and small and one person is very average, and the two people are completely different psychological states.

Iv. Report Analysis:

1. Indicators: HRV (Heart Rate Variability), pressure and other comprehensive indicators

Indicators include:

SDNN is the standard deviation of the sinus heart beat RR interval (NN interval for short), which is used to evaluate autonomic nerve activity. The higher the value, the better the activity.

rMSSD, which is the root mean square of the difference between adjacent RR periods, is used to assess parasympathetic nerve activity, with higher values indicating more relaxation.

PNN50, the percentage of the number of intervals between adjacent RRS greater than 50 milliseconds in the total number of cardiac muscles, is used to assess the degree of heart rate variability. The greater the value, the greater the heart rate variability, the better the status.

Stress index, used to assess the degree of stress, the lower the value, the less stress.

Autonomic balance, which is used to assess the proportion of sympathetic and parasympathetic nerves, is the best balance.

2. Emotional state:

Real-time state: People's emotions are constantly fluctuating and changing, and real-time state is a real-time reflection of inner fluctuations.

Result status: According to the change of RR interval (the time limit R-R interval between two R-waves on the ECG),

Comprehensive HRV (heart rate variability), pressure and other indicators change characteristics, in sufficient time range of measurement, analysis of human status characteristics.

The difference between the 5 main result status categories:

Anxiety: The brain keeps running, worrying, worrying will produce anxiety (if it is short thinking, short anxiety is fine, but anxiety will slowly develop in the direction of too much pressure).

Excessive pressure: anxiety has been going up, do not relax and adjust, there may be overpressure, overpressure for a long time, you need others to help decompress, and you can not relax. Low, depressed, not active enough: not people are not active enough, but autonomic nervous activity, regulation is not active enough, need to improve activity, such as expanding interests, enhancing sports and so on. Relaxed and full which is good: relaxed, the state of mind is very good, the pressure is very small, many things are nothing to him, so the pressure on him will be offset a lot. Full, stressed, but adjusted, the whole person is in a productive state of work. Both are good, each has its advantages.

3. Analysis and summary: Build a comprehensive model of multiple indicators of HRV and stress index to analyze people's emotional state,

Psychological state -- a unique domestic patented technology.

Emotions, like human character, have their own characteristics and characteristics.
