Solution Overview

Problem

In multiplayer virtual reality applications, the influx of pose data from multiple players' head-mounted displays (HMDs) leads to performance issues due to excessive data transmission, impacting seamless user experiences.

Innovation Solution

A control device determines zones and relative positions to assign message transmitting frequencies, selectively transmitting pose data based on these frequencies to mitigate data overload, using a storage circuit and processor to manage message transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous synchronization of pose data from all players is implemented, then user experience quality is improved, but device performance deteriorates due to data overload

Engineering Contradiction:
Improveuser experience qualityVSAvoiddevice performance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements differential message transmission frequencies based on spatial zones. Players in distant zones receive messages at lower frequencies compared to players in nearby zones, creating localized quality adjustments that maintain overall system reliability while reducing individual device processing loads

Inventive Principle:
Principle #3Local quality

2Measurement precision

If message transmission frequency is increased for all players, then synchronization accuracy is improved, but data transmission load increases

Engineering Contradiction:
Improvesynchronization accuracyVSAvoiddata transmission load
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system assigns different message transmission frequencies to different spatial zones. Zones closer to the focal player receive higher frequency updates for better synchronization accuracy, while distant zones receive lower frequency updates, reducing overall data transmission load across the network

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The message transmission frequency is dynamically adjusted based on the relative position between players and zones. As players move through different zones, their message reception frequency changes automatically, optimizing the balance between synchronization accuracy and data load in real-time

Inventive Principle:
Principle #15Dynamics

AI summary

The embodiments of the disclosure provide a method for managing message transmission, a control device, and a computer readable storage medium. The method includes: determining a first zone where a first client device locates among a plurality of predetermined zones; determining a first relative position between the first zone and a second zone among the plurality of predetermined zones; determining a first message transmitting frequency associated with the second zone based on the first relative position; and in response to determining that a second client device locates in the second zone, providing at least a first part of a plurality of first messages from the first client device located in the first zone to the second client device based on the first message transmitting frequency.
