AI summary

An electronic device may include: a rotation detection module configured to detect rotation parameters of a rotating body; a haptic module configured to generate vibration according to a vibration pattern; a display configured to display a user interface; a memory; and a processor electrically connected with the rotation detection module, the haptic module, the display, and the memory. The memory may store instructions that, when executed, cause the processor to: determine vibration parameters based on the rotation parameters detected by the rotation detection module; generate a vibration pattern based on the vibration parameters; and output a user interface corresponding to the generated vibration pattern on the display.
