Combined Audio Vibration Waveform Generation for Realistic Feedback
Solution Overview
Problem
Conventional techniques for providing vibration feedback in information processing systems lack realism, as they primarily rely on positional vibration control without effectively integrating audio and vibration waveforms to enhance user experience.
Innovation Solution
An information processing system that combines vibration and audio waveforms, allowing for realistic vibration feedback by generating a combined waveform based on input signals, which can be output simultaneously with sound, and adjusting vibration patterns based on specific conditions or object interactions.

Engineering Contradiction Analysis
1Reliability
If conventional positional vibration control is used, then the system is simple to operate, but the vibration feedback lacks realism
Solution Approach 1:
The patent combines audio waveforms and vibration waveforms into a unified waveform signal that is processed and output together. The waveform generation unit integrates both audio data and vibration pattern data into a single combined waveform, which is then output to both the audio output unit and vibration output unit, ensuring synchronized and realistic feedback.
Solution Approach 2:
The waveform generation unit serves multiple functions: it processes audio waveforms, generates vibration waveforms, combines both waveforms, and outputs them to different devices. This multi-functional approach eliminates the need for separate processing systems for audio and vibration, reducing overall system complexity while improving realism.
2Reliability
If audio and vibration waveforms are combined, then realistic vibration perception is achieved, but synchronization timing becomes complex
Solution Approach 1:
The system performs preliminary processing of both audio and vibration waveforms in the waveform generation unit before output. By pre-combining the waveforms and preparing the synchronized signal in advance, the system eliminates timing delays and ensures that both audio and vibration outputs are perfectly synchronized when delivered to the user.
3Reliability
If vibration feedback is enhanced with audio integration, then user experience is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts vibration parameters (amplitude, frequency, duration) based on the audio waveform characteristics and game conditions. By changing vibration parameters to match the audio content, the system provides high-quality synchronized feedback while consuming only the necessary amount of energy, avoiding excessive power usage.

AI summary
A determination section determines whether or not contact of an object has occurred, based on an orientation, of a controller, calculated by an orientation calculation section. A first waveform generation section generates a first vibration waveform when the determination section determines that the contact of the object has occurred. An audio vibration waveform generation section generates an audio vibration waveform based on a sound signal. An output section outputs the sound signal and outputs a signal representing a combined waveform obtained by the first vibration waveform and the audio vibration waveform based on the sound signal being combined with each other, when the determination section determines that the contact of the object has occurred.
