Tactile Bass Response via Playback Delay Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User computing devices and audio output devices often fail to provide sufficient tactile bass response, and generating low bass tones can drain battery life, leading to suboptimal audio experiences.
Innovation Solution
A method where a first user device determines the playback delay between itself and a second user device, synchronizing the output of an audio signal with a tactile bass response representation using haptic actuators, ensuring that the tactile feedback is coordinated with the audio output, and adjusting volume based on device positioning to conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an audio output device generates low bass tones to provide tactile bass response, then the tactile bass response is improved, but the battery life is reduced due to significant power consumption
Solution Approach 1:
The system divides the bass response generation task between two devices: the audio output device (second user device) generates the audio bass signal, while a separate computing device (first user device) with haptic actuators generates the tactile bass response. This segmentation allows the audio device to avoid power-intensive low-frequency amplification while still providing tactile feedback through the haptic device.
Solution Approach 2:
The computing device acts as an intermediary that receives the audio signal, processes it to extract bass frequencies, and converts them into haptic feedback through actuators. This intermediary approach allows tactile bass response to be generated without requiring the audio output device to consume excessive power for low-frequency sound generation.
2Reliability
If the audio output device provides sufficient bass response, then the audio experience is improved, but the device complexity increases due to additional components required
Solution Approach 1:
The computing device performs multiple functions: it processes audio signals, extracts bass frequencies, generates tactile feedback patterns, and synchronizes output with the audio device. By making the computing device multi-functional, the system avoids adding dedicated specialized components to the audio output device, thereby reducing overall system complexity.
Solution Approach 2:
The computing device uses its own existing haptic actuators and processing capabilities to generate the tactile bass response, rather than requiring the audio output device to incorporate additional hardware. The system leverages resources already available in the computing device to provide enhanced audio experience.
3Reliability
If the tactile bass response is synchronized with the audio signal, then the audio experience is improved, but the time delay measurement and coordination complexity increases
Solution Approach 1:
The system uses feedback mechanisms to measure and compensate for time delays. The computing device monitors the audio signal playback timing and adjusts the haptic feedback timing accordingly to achieve synchronization. This feedback-based approach provides accurate synchronization without requiring overly complex pre-coordination protocols.

AI summary
Example aspects of the present disclosure are directed to providing tactile bass response by a user device. For instance, a first audio signal can be caused to be output by a first user device and a second user device. A playback delay can be determined between the output of the first audio signal by the first user device and the output of the first audio signal by the second user device. At a first time, the second user device can be caused to output a second audio signal. The first user device can be caused to execute a tactile bass response representation associated with the second audio signal, such that the tactile bass response is executed at a second time, the second time being determined based at least in part on the temporal delay.
