Abstract: A gesture recognition method and a related apparatus are provided, to obtain a first point cloud data set by filtering an original point cloud data set collected by a radar apparatus. The first point cloud data set includes a plurality of frames of first point cloud subsets, the first point cloud subset includes a first cluster center, the first cluster center is a cluster center of a plurality of pieces of point cloud data in the first point cloud subset, a maximum horizontal distance between any two first cluster centers meets a first preset condition, and duration of the first point cloud data set meets the first preset condition. Point cloud data whose motion track does not match gesture motion can be effectively filtered out. Gesture recognition is performed by using the first point cloud data set obtained by filtering.

Abstract: A method for customizing a key of a foldable device, a device, and a storage medium are provided. When the foldable device is in a folded state, a touchscreen of the foldable device is divided into three regions: a primary screen, a back screen, and a secondary screen. According to the method for customizing a key, the foldable device receives a first user operation used to indicate the foldable device to add a custom key on the back screen or the secondary screen, and then obtains a physical state of the foldable device. If the foldable device is in a folded state, the custom key is added on the back screen or the secondary screen based on the first user operation.
