Abstract:
Haptic effects are dynamically generated for content presentation on a device through analysis of the content. During content playback, audio data for the content may be analyzed to determine low frequency audio data. The low frequency audio data is mapped from a low frequency range to a haptic control frequency range of one or more haptic actuators included in the device. This mapping may be used to generate a control signal to drive the one or more haptic actuators. The haptic effects and the content may be synchronized to one another during the presentation of the content on the device. The haptic actuator control signal may be amplified proportionally to the amplitude of the low frequency audio data.
