On June 26th, 9:00am-12:00pm, Professor Zhu Jianhua from the Department of Media and Communication and School of Data Science, City University of Hong Kong gave a fascinating lecture on "Computational Methods and Intelligent Communication", hosted by Associate Professor Yang Ya from the School of Journalism and Communication, Beijing Normal University.
On June 26, 2:00-4:30 pm, the workshop invited Beijing Hengzhi Technology Co., Ltd. to train the participants on experimental techniques of cognitive neurocommunication, which was hosted by Mr. Xiu Lichao from the School of Journalism and Communication.
The training is divided into two parts, the first part isHengzhi TechnologyThe technicians explained the principle and application of EEG technology and NIR spectroscopy technology, and the second part was: experience and practical operation of Cortivision NIR brain imaging equipment in Poland and SmartBCI portable EEG equipment in Russia.
Firstly, technical engineer Jin Can, the technical theoretical consultant of Beijing Hengzhi Technology Co., Ltd. explained the EEG principle explanation and application demonstration.
In the EEG technology section, theJin CanTechnical EngineerThe participants were first introduced to the principles and extraction of EEG (electroencephalogram), which is the spontaneous, rhythmic and integrated electrical activity of brain cells, and ERPs, which are event-related potentials with two important characteristics: constant waveform and constant latency.
Next, the classical ERPs components and studies are mainly explained, introducing ERPs naming rules and classification, P300 components and Oddball paradigm, miss-matching negative wave (MMN) and N400.Jin CanTechnical EngineerFrom the perspective of experimental design in communication, the application context and influencing factors of P300 under the context updating (context updating) theory model are introduced, while N400 can be applied to the field of PR, and experiments can be designed according to the characteristics of each ERPs component in the field of news communication research.
Finally, the integration of EEG with communication science is presented, such as the ability to apply EEG techniques to measure the communication effect (with what effect) in Lasswell's 5w theory of communication.
SecondlyTechnical engineer Shan Keqiu, technical theoretical consultant of Beijing Hengzhi Technology Co.ExplainedNear-infrared spectroscopyPrinciple and application of the technology.
How to use the difference in absorbance of NIR light by two hemoglobins to detect the corresponding changes in bleeding oxygen is described, and finally the spatial resolution characteristics of NIR are combined.
In the section on principles and applications of functional near-infrared spectroscopy (fNIRS), Shan KeqiuTechnical EngineerThe four parts of fNIRS imaging principle, advantages and limitations, advantageous research areas and case study sharing are introduced.
Current dominant research areas of fNIRS are infant brain function studies and simulated driving, among others. And in the field of communication research, fNIRS may be applied in the communication mode dimension, such as comparing the neural synchronization and the difference in teaching effectiveness between face-to-face and computer-mediated teaching.
After the explanation, Jin Can technical engineer demonstrated for the participants through the angle of electrode cap wearing and removal method.
In the AGI era, the formation of a new communication ecology will certainly lead to new communication methods and concepts. Academia is also facing brand new challenges and breakthroughs. We believe that through joint efforts and exchanges, we can create a more open, innovative and inclusive academic environment.
Hengzhi Technology will continue to be committed to promoting the development and application of human factors engineering technology and neurocommunication, bringing more innovative and cutting-edge content to the communication and academic fields. Thank you for your support and participation, and we look forward to meeting you again in the future to discuss together!Human Factors Engineering andNeuropropagationNew challenges and opportunities in this era.
I wish you all the best in your academic and research endeavors!
