Haptic and Audio UI Synchronization Through Delayed Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in harmonizing different types of user interfaces, such as vibrations and sounds, leading to asynchronous outputs that degrade user experience and hinder efficient information transfer.
Innovation Solution
The implementation of a harmonious interaction between user interfaces through synchronized output of vibrations and sounds, where the processor delays vibration output and changes sound output modes to ensure timely synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If vibration and sound are output simultaneously using different hardware and software logics, then the output speed of each interface is improved, but synchronization between vibration and sound deteriorates
Solution Approach 1:
The patent applies preliminary action by delaying the vibration output timing to align with sound output. The processor intentionally postpones the vibration signal generation until after the sound has been output, ensuring that both interfaces are synchronized in terms of user perception. This resolves the contradiction by maintaining fast sound output while adjusting vibration timing to achieve harmony between the two interfaces.
2Adaptability or versatility
If different hardware and software logics are used for vibration and sound output, then the functionality and versatility of the device is improved, but the complexity of coordinating and synchronizing these interfaces increases
Solution Approach 1:
The patent introduces an intermediary approach by using a unified timing reference or synchronization mechanism that coordinates between the vibration and sound output systems. The processor acts as an intermediary that manages the timing and coordination of different hardware components, allowing them to operate independently with their own optimized logics while maintaining overall synchronization through centralized timing control.
3Reliability
If vibration output is delayed to synchronize with sound, then synchronization is improved, but the response time of the vibration interface deteriorates
Solution Approach 1:
The patent applies inversion by reversing the conventional approach of simultaneous output. Instead of trying to make vibration respond immediately and waiting for sound to catch up, the system delays vibration output until after sound has been delivered. This inverted timing strategy ensures that both interfaces are perceived as synchronized by the user, while maintaining the natural fast response characteristics of sound output.

AI summary
An electronic device may include: a memory, a display, a haptic module comprising haptic circuitry, a sound module comprising audio circuitry, and a processor. The processor may be configured to: detect an event for an output of vibration and sound, delay the output of the vibration, change a sound output mode from a first mode to a second mode for fast output while the output of the vibration is delayed, output the sound using the sound module in the second mode, and output the delayed vibration through the haptic module to be synchronized with the output of the sound. As the sound output mode is changed to the second mode, a sound output path may be opened. The sound output path may be changed from the first path for non-fast output to the second path for fast output.
