Operation identification method and device

The present invention relates to the field of mobile terminals and discloses an operation identification method and device. The method comprises: acquiring a data sequence collected by a sensor in a mobile terminal, wherein the data sequence comprises n pieces of data collected in predetermined time intervals; high-pass filtering the data sequence to obtain n pieces of filtered data; detecting whether the filtered data exceeds a predetermined threshold for each of the filtered data; and if the filtered data exceeds the predetermined threshold, generating an identification result for indicating an occurrence of a shaking operation of the mobile terminal. The present invention solves the problem in which an identification process is interfered due to factors such as the gravitational acceleration, and the constant acceleration occurred when riding in a car resulting in a high possibility of false identification of shaking operations, and therefore provides the effects of an elimination of interferences such as the constant acceleration using the high-pass filtering and an improved identification accuracy for shaking operations.
