Head-Mounted Display Content Reproduction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices struggle to allow users to immerse in virtual worlds while effectively responding to important events in the real world without interrupting their experience.
Innovation Solution
The integration of circuitry that controls content reproduction based on the importance of events detected by sensors and cameras, enabling users to monitor and respond to real-world events while maintaining immersion in virtual environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head-mounted display completely blocks the user's view of the outside world to enhance immersion, then the immersion in virtual world is improved, but the user's ability to respond to real-world events deteriorates
Solution Approach 1:
The display screen is divided into multiple regions: a first region for displaying virtual content and a second region for displaying real-world video. This segmentation allows simultaneous presentation of both virtual and real information without completely blocking either, resolving the contradiction between immersion and real-world awareness.
Solution Approach 2:
The patent merges virtual content display with real-world video display on the same screen. The video acquisition unit captures real-world scenes while the display unit simultaneously shows both the captured video and virtual content, combining both functions in one interface to maintain both immersion and situational awareness.
2Object-affected harmful factors
If the head-mounted display allows the user to see through the display screen to view the outside world, then the user's awareness of real-world events is improved, but the immersion in virtual world deteriorates
Solution Approach 1:
The display screen is segmented into distinct regions where virtual content and real-world video are displayed separately. This allows the user to access real-world information without completely breaking the virtual environment, as the virtual content remains visible in its designated region.
Solution Approach 2:
Instead of using a single transparent display mode, the patent introduces a spatial dimension by dividing the screen into multiple display regions. This dimensional approach allows layering of virtual and real content in different screen areas, maintaining immersion while providing real-world awareness.
3Object-affected harmful factors
If the head-mounted display interrupts content playback to show real-world events, then the user's ability to respond to important events is improved, but the immersion and continuity of virtual experience deteriorates
Solution Approach 1:
Rather than interrupting virtual content playback, the system segments the display to show real-world video alongside virtual content. This allows continuous presentation of both without breaking the virtual experience flow, while still enabling response to real-world events.
Solution Approach 2:
The patent maintains continuous playback of virtual content while simultaneously acquiring and displaying real-world video in a separate region. This continuity approach ensures the virtual experience flows uninterrupted while real-world information remains accessible, avoiding the need to pause or interrupt either stream.

AI summary
An apparatus may include circuitry configured to control reproduction, at a head-mounted display device, of content, based on a determination of importance of an event occurring around the head-mounted display device.
