Embodiments of this application provide a method for displaying a two-dimensional code and an electronic device. The method is performed by an electronic device, and includes: obtaining first sensor data, where the first sensor data is collected at a first moment; if it is determined, based on the first sensor data, that a first action of a user corresponding to the first moment is a preset action, determining whether the user performs a wrist turning action within a preset duration range starting from the first moment; and displaying a preset two-dimensional code page when the user performs a wrist turning action within the preset duration range. In the method, a process of presenting a two-dimensional code by the user can be simple and efficient.

Method for displaying two-dimensional code and electronic device

This application relates to the field of artificial intelligence technologies, and provide a knuckle operation identification method and an electronic device. According to this application, when a knuckle performs an operation on different touch regions of a touch panel, an acceleration signal may have different change trends. A touch feature is extracted from a touch signal for determining a contact area and a contact location, and an acceleration feature is extracted from the acceleration signal for determining a magnitude of a touch on a screen. A capacitor binary classification model is used at the front, to extract a confidence score indicating a correlation to a knuckle from a capacitor signal. Then, feature fusion is performed on the acceleration feature, the confidence score, and the touch feature, and a fused feature is input into a knuckle classification model, to obtain a better classification effect.
