Electronic Device Vibration Synchronization with External HMDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices lack the capability to provide immersive vibration experiences when mounted to external devices, such as Head-Mounted Devices (HMDs) or game pads, as they do not effectively synchronize vibration patterns between internal and external vibration devices based on content output.
Innovation Solution
An electronic device with a communication interface and at least one vibration device, which determines and transmits vibration information to an external device to synchronize the vibration of both internal and external vibration devices based on content, such as image and sound directionality, to create an immersive experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vibration information is transmitted to external devices to enable synchronized vibration, then user immersion is improved, but device complexity increases
Solution Approach 1:
The electronic device serves multiple functions: it acts as both a content output device and a vibration coordination device. The processor not only processes content but also generates and transmits vibration information to external devices, making the electronic device universal in its functionality and thereby improving user immersion without requiring separate dedicated vibration control systems
Solution Approach 2:
The communication interface acts as an intermediary between the electronic device and external vibration devices. It transmits vibration information (timing, intensity, patterns) to external devices, enabling synchronized vibration without direct complex integration between the electronic device and each external device, thus managing complexity while achieving coordinated vibration effects
2Ease of manufacture
If vibration synchronization is implemented based on content output, then user immersion is improved, but communication overhead increases
Solution Approach 1:
The vibration information (timing, intensity, patterns) is extracted from the content output process and transmitted separately to external devices. This allows the main content output to proceed independently while vibration synchronization is handled through a dedicated communication channel, reducing the communication overhead by separating these functions
Solution Approach 2:
The electronic device determines vibration information in advance based on the content to be output, before the actual content playback. This preliminary determination allows vibration patterns to be pre-synchronized with content timing, reducing real-time communication overhead during content playback while maintaining immersion
