    摘要： Embodiments of this application provide a human-computer interaction method, a human-computer interaction apparatus, and a storage medium. The method includes: displaying a human-computer interface, where the human-computer interface includes an operable object and a visual stimulus region; and executing a first operational command on the operable object, where the first operational command is determined based on a first signal, the first signal is an electroencephalography signal generated when a user gazes at a first region, the first region is one of a plurality of regions around the visual stimulus region, different electroencephalography signals are generated when the user gazes at different regions of the plurality of regions, and the different electroencephalography signals indicate to execute different operational commands related to the operable object. According to this application, the user does not need to gaze directly at a visual stimulus and can deliver different operational commands quickly, which improves user experience.

    摘要： The present invention relates to an electrochemical sensing intelligent chamber with integrated environmental parameters, comprising a chamber body of the intelligent chamber for electrochemical sensing and detection. A communication control unit, a temperature monitoring unit, a gas detection unit and an electrochemical sensing and detection unit are arranged in the chamber body. An environmental parameter monitoring unit that can monitor temperature and gas is integrated; and all monitored environmental variables may be uploaded to a smart phone for a user to view. Operation steps in the electrochemical sensor measurement process conducted in the chamber body are fully automated.

    摘要： The present invention provides an asymmetric EEG-based coding and decoding methods for BCIs, the BCI system includes an evoked stimulus module, an acquisition module and an EEG signal data set including a training set Xk and a testing sample Y, and an EEG signal decoding module; the evoked stimulus module sends a hybrid coding visual stimulus to subjects to evoke a specific EEG signal as required; the acquisition module obtains data information by amplifying and filtering the EEG signal so as to constitute EEG signal module; the decoding module coverts the data information into an instruction set for outputting the coding method of the present invention uses asymmetric characteristics of brain electrophysiological activity response to stimulus, combines with coding strategies such as SDMA, CDMA, FDMA and phase division multiple access coding.
