  • Publication number: 20240419249
    Abstract: A method for creating tactile effect in real time through a gesture and a related device includes: acquiring a target graphic file, automatically splitting the target graphic file into tracks, and displaying track parameter of the track; identifying whether the track has the track parameter; detecting an inputted gesture tactile signal in real time, generating a corresponding real-time vibration signal according to a preset rule, synchronously writing the real-time vibration signal as input parameter to track parameter, and simultaneously driving a vibration unit to produce a corresponding vibration feedback effect; and binding all the real-time vibration signals generated within a playback duration of the target graphic file to the target graphic file to form a final vibration signal of the target graphic file. In the method, a user can customize tactile effects for target audio and video files, which is convenient to operate and brings better user experience.

  • Patent number: 7941298
    Abstract: An apparatus, computer program product and method of analyzing complex signals. Independent versions are generated for the complex signal, e.g., by adding multiple instances of white noise. Intrinsic mode functions (IMFs) are extracted from each of the independent versions, e.g., using Empirical Mode Decomposition (EMD). Corresponding IMFs from each independent version are combined into Ensemble IMFs (EIMFs), e.g., taking the mean of the corresponding IMFs.
