HMD Image Sharing via Adaptive Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted devices (HMDs) provide personalized virtual reality content to each user, preventing simultaneous sharing of the same image with multiple users, as they are designed to display binocular image data specific to individual users.
Innovation Solution
An electronic device for HMDs that includes a processor to determine whether an external device stores virtual reality content and transmits appropriate data, such as binocular or mono image data, based on this determination, enabling image sharing between HMDs and other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If HMD provides personalized binocular image data to each user, then image quality and user experience are improved, but image sharing capability deteriorates
Solution Approach 1:
The patent segments image data into different types (binocular image data for HMDs and mono image data for non-HMD devices) and transmits appropriate segments to different devices. The processor determines device type and selectively transmits either binocular or mono image data, enabling both high-quality HMD experience and sharing capability with regular devices.
Solution Approach 2:
The patent changes the parameter of image data format based on the receiving device. When the external device is an HMD, binocular image data is transmitted; when it is a non-HMD device, mono image data is transmitted. This parameter adaptation resolves the contradiction between optimized HMD performance and broad sharing capability.
2Adaptability or versatility
If HMD transmits binocular image data to external devices, then sharing capability is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The patent extracts only the necessary image data type for each receiving device. Instead of always transmitting full binocular image data, the system extracts and transmits only mono image data to non-HMD devices that cannot utilize binocular format, thereby improving transmission efficiency while maintaining sharing capability.
Solution Approach 2:
The transmission efficiency is improved by changing the image data parameter (from binocular to mono) based on the receiving device's capabilities. This parameter adaptation ensures that data transmission is optimized for each device type, preventing unnecessary data transmission to devices that cannot process the full format.
3Adaptability or versatility
If HMD determines external device type and content storage, then image sharing compatibility is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the HMD processor determines the external device type and content storage status, then uses this information to select the appropriate image data format for transmission. This feedback loop enables automatic adaptation to different devices without requiring complex manual configuration, improving compatibility while managing complexity through automated decision-making.

AI summary
An electronic device for a head-mounted device (HMD) is provided. The electronic device includes a display, a memory configured to store virtual reality content, a processor configured to play back binocular image data based on the virtual reality content on the display, and a communication circuit configured to communicate with an external device. At this time, the processor is configured to determine whether the virtual reality content is stored in the external device and to determine data to be transmitted to the external device based on the determined result.
