Wearable device based interactive method, wearable device based interactive device and wearable device

An embodiment of the invention discloses a wearable device based interactive method, a wearable device based interactive device and a wearable device. The interactive method includes the steps: respectively acquiring receiving frequency information of a receiving wave signal and original frequency information of a transmitting wave signal corresponding to the receiving wave signal; determining position adjusting data of the wearable device relative to a wearing surface in the position adjusting process of the wearing surface of the wearable device according to Doppler effect, the receiving frequency information and the original frequency information; meeting at least one set condition at least responding to the position adjusting data, and executing at least one operation. Corresponding operations are automatically executed by acquiring position adjusting information of the wearable device relative to the wearing surface, and a convenient and natural mode for interacting with the wearable device is provided for users.
