AUDIO AND HAPTIC SIGNAL PROCESSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17880508 titled 'AUDIO AND HAPTIC SIGNAL PROCESSING

Simplified Explanation

The patent application describes a method for generating haptic drive signals based on an input audio signal. The method involves analyzing the audio signal to derive data components that represent the behavior of an audio speaker when driven by the input audio signal. Each data component is associated with a specific frequency range. From these data components, haptic drive components are determined, and a gain is selected for each frequency range. The selected gains are then applied to the haptic drive components to produce gain-adjusted haptic drive components. Finally, a haptic drive signal is determined from the gain-adjusted haptic drive components, which can be used to drive a haptic actuator and produce a desired mechanical behavior.

• The method analyzes an input audio signal to derive data components representing the behavior of an audio speaker.
• Haptic drive components are determined from the data components.
• Gains are selected for each frequency range to adjust the haptic drive components.
• The gain-adjusted haptic drive components are used to determine a haptic drive signal.
• The haptic drive signal can be used to drive a haptic actuator and produce a desired mechanical behavior.

Potential applications of this technology:

• Enhancing virtual reality experiences by providing haptic feedback synchronized with audio.
• Improving gaming experiences by adding realistic haptic effects based on audio cues.
• Enabling immersive multimedia content by integrating haptic feedback with audiovisual presentations.
• Assisting individuals with hearing impairments by providing tactile feedback based on audio signals.

Problems solved by this technology:

• Lack of synchronized haptic feedback with audio content.
• Limited realism in gaming experiences due to the absence of haptic effects.
• Inability to provide tactile feedback for individuals with hearing impairments.
• Difficulty in creating immersive multimedia experiences without haptic feedback.

Benefits of this technology:

• Enhanced user experience through synchronized audio and haptic feedback.
• Increased realism and immersion in virtual reality and gaming applications.
• Improved accessibility for individuals with hearing impairments.
• Expanded possibilities for creating immersive multimedia content.

Original Abstract Submitted

Audio and haptic signal processing systems and methods are provided. There is provided a method for haptic drive signal generation. The method comprises receiving an input audio signal for driving an audio speaker. The method further comprises deriving, from the audio signal, data components indicative of behaviour of the audio speaker when being driven by the input audio signal, each data component being associated with a respective frequency range. The method further comprises determining a haptic drive component from each data component. A gain is selected to provide to each of the haptic drive components, the gain being selected for each respective frequency range. Each selected gain is applied to the respective haptic drive component to produce gain adjusted haptic drive components. A haptic drive signal is determined from the gain adjusted haptic drive components, the haptic drive signal being so as to produce a mechanical behaviour of the haptic actuator when the haptic drive signal is used to drive the haptic actuator
