Solution Overview

Problem

Content sharing from head-mounted display (HMD) devices to external devices often results in compatibility issues due to differences in attributes such as binocular management, screen ratios, and sound support, leading to abnormal reproduction and impaired user immersion.

Innovation Solution

An electronic device with a communication interface, memory, and processor that identifies attribute information of external devices and converts content formats to match the capabilities of the receiving device, ensuring optimized sharing and improved user immersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If content is shared directly from HMD device to external device without format conversion, then sharing speed is improved, but compatibility with external device attributes deteriorates

Engineering Contradiction:
Improvecontent sharing speedVSAvoidcompatibility with external device attributes
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary identification of external device attributes (screen ratio, binocular management capability, sound support) before content sharing. Based on this pre-identification, the content format is proactively converted to match the external device's characteristics, preventing compatibility issues before they occur during the sharing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent dynamically changes content parameters (format, resolution, stereo/monocular configuration) based on the identified attributes of the external device. The processor adjusts these parameters in real-time to ensure the shared content is compatible with the receiving device's capabilities while maintaining optimal sharing efficiency.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If content format is converted to match external device attributes, then compatibility is improved, but processing time increases

Engineering Contradiction:
Improvecompatibility with external device attributesVSAvoidformat conversion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system identifies external device attributes and determines the appropriate content format in advance, before the actual content sharing begins. This preliminary preparation minimizes the conversion time during the sharing process itself, as the transformation parameters are already determined based on pre-identified device characteristics.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If content is shared without considering external device attributes, then sharing simplicity is improved, but user immersion deteriorates due to abnormal reproduction

Engineering Contradiction:
Improvesharing simplicityVSAvoidcontent reproduction quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically identifies external device attributes and performs format conversion without requiring user intervention. The processor self-adapts the content format based on the receiving device's characteristics, maintaining sharing simplicity while ensuring reliable, high-quality reproduction on the external device.

Inventive Principle:
Principle #25Self-service

AI summary

An electronic device that interacts with a head mounted display (HMD) device is provided. The electronic device includes a communication interface, a memory, a display, and at least one processor electrically connected to the communication interface, the memory, and the display. The at least one processor is configured to receive an event signal related to sharing of contents with at least one external device or receive request information related to sharing of contents from the at least one external device through the communication interface, identify attribute information of the at least one external device, convert a format of some of one or more contents, which are stored in the memory, such that the format of one or more contents corresponds to the identified attribute information, and transmit the contents to the at least one external.
