Solution Overview

Problem

Virtual reality headsets create isolated environments, making it difficult to share immersive experiences with others.

Innovation Solution

Systems and methods for sharing virtual reality environments between master and follower devices, using head-mounted displays (HMDs) with transceivers, displays, and processors to synchronize and transmit field of view data, allowing for coordinated VR experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If virtual reality headsets create isolated environments, then immersive experience is improved, but shareability with others deteriorates

Engineering Contradiction:

Improveimmersive experienceVSAvoidshareability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments the VR experience into master and follower roles, where the master device maintains the primary isolated immersive environment while follower devices receive synchronized views. This segmentation allows the master device to preserve immersion while enabling multiple devices to participate in the shared experience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a communication system as an intermediary that transmits field of view data between master and follower devices. This intermediary enables sharing without breaking the isolation of individual VR headsets, as the synchronization occurs through data exchange rather than direct environmental sharing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If field of view data is transmitted between multiple HMDs, then shareability is improved, but computational resource consumption increases

Engineering Contradiction:

ImproveshareabilityVSAvoidcomputational resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system extracts only the essential field of view data needed for synchronization rather than transmitting complete environmental data. By taking out only the necessary components (FOV parameters, orientation data), the system enables sharing while minimizing computational and energy resources required for data transmission and processing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements partial action by synchronizing only the portions of the VR environment that are currently in the field of view of each device. Rather than synchronizing the entire virtual environment, the system focuses computational resources on transmitting and processing only the relevant FOV data, reducing overall resource consumption.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method and apparatus for coordinating a master/follower device arrangement in a virtual reality (VR) environment is disclosed. A head mounted display (HMD) includes a transceiver, a display, and a processor coupled to the transceiver and display. The processor is configured to control the transceiver to receive, from at least one other HMD, data related to a field of view (FOV) of the at least one other HMD in a virtual reality (VR) environment. The processor is further configured to generate, using the data related to the FOV of the at least one other HMD, an FOV of the HMD in the VR environment.
