  • Tactile sensation presentation device, display device, data terminal device, and tactile sensation presentation method
    Patent number: 12510969
    Abstract: A signal processing device includes: a fundamental frequency calculation unit for calculating a fundamental frequency from the touch location; a target waveform calculation unit for modulating a waveform of the fundamental frequency by an envelope waveform of a vibration according to the stimulation type to be presented at the touch location, to calculate a target waveform for the vibration to be presented at the touch location. The fundamental frequency calculation unit calculates the fundamental frequency based on a first distance so that the shorter the first distance is, the higher the fundamental frequency is, the first distance being a minimum distance among distances between touch locations and between a touch location and a support of a panel.
