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.

Abstract: A method is implemented by an electronic device to mark a position of a home device. The method includes that the electronic device receives a first operation of a user, where the first operation is used to trigger the electronic device to mark a position of a first home device in a plurality of home devices. In response to the first operation, the electronic device obtains, by using a UWB chip, spatial position-attitude information of the electronic device when the electronic device separately points to the first home device in n orientations, and calculates spatial position information of the first home device based on the spatial position-attitude information of the electronic device in the n orientations.

Abstract: A method includes a device in an area 1 that requests a ultra-wideband (UWB) base station in the area 1 to measure an initial position, and starts inertial measurement unit (IMU) measurement. The device moves to an area 2, and the device requests to measure distances between each UWB base station in the area 2 and at least three locations. The device returns to the area 1, and requests the UWB base station in the area 1 to measure an end point position. The device corrects coordinates of the device in the area 2 calculated using data obtained through the IMU measurement based on the measured end point position. Calculate the coordinates of each UWB base station in the area 2 based on the corrected coordinates in the area 2 and the measured distances between each UWB base station and the device in the area 2.
