    Abstract: 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.

    Abstract: The present disclosure provides a drain-gate voltage excitation and source-drain current acquisition system and method for gas-sensitive organic field effect transistors (OFETs). The system includes an acquisition device and a gas-sensitive OFET array. The device includes a microcontroller module, a power supply management module, a voltage excitation module, a voltage regulation module, a transimpedance amplifier (TIA) module, a fully-differential low-side current detection module, a voltage acquisition module, a signal transmission module and an array switching module. In the present disclosure, the real-time monitoring of various harmful gases and the performance testing of the gas-sensitive OFETs are realized. The device has two current detection modes, thereby not only stabilizing drain electric potentials, but also enabling drain-source currents to be measured with sufficient accuracy.
