Solution Overview

Problem

Providing a consistent and enjoyable extended reality (XR) experience for multiple users in different physical environments is challenging due to varying layouts and obstacles, which can hinder seamless interaction and movement.

Innovation Solution

The system receives information about the different physical layouts of user environments and assigns each user a portion of a virtual map, adjusting perspectives based on their physical environment to create a cohesive XR experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single shared virtual space is provided for multiple users, then users can participate in a group XR experience together, but users in different physical environments experience inconsistent and difficult navigation due to varying layout sizes and obstacles

Engineering Contradiction:

ImproveXR experience consistencyVSAvoidvirtual map positioning

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by providing different virtual map positioning data to different XR devices based on their specific physical environments. Each user receives customized positioning information tailored to their local spatial constraints and layout characteristics, ensuring that the XR experience adapts to local conditions rather than applying a uniform positioning system to all users.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the virtual map positioning data according to different physical environments. Instead of providing a single unified positioning system, the system divides the positioning data into environment-specific segments, allowing each user to navigate their portion of the shared virtual space according to their local physical constraints.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If different physical environments are accommodated with customized virtual positioning, then each user experiences a consistent XR environment adapted to their space, but the system complexity and data processing requirements increase

Engineering Contradiction:

Improveuser movement freedomVSAvoidpositioning data management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring different virtual map positioning data for different physical environments before users enter the shared XR space. The system prepares environment-specific positioning configurations in advance, so that when users join, their XR devices are already configured with appropriate positioning data matched to their physical space characteristics, eliminating the need for real-time adaptation during the experience.

AI summary

Methods, systems, and apparatuses are described for providing XR experiences to multiple users. A plurality of XR devices might participate in a group XR experience. Physical environment data may be determined for each XR device. Virtual play areas for each of the XR devices may be determined. The different virtual play areas may be fit into different areas of a predefined virtual play area, and/or may be combined to form a combined virtual play area. Each XR device might be provided a different portion of the virtual play area. The XR devices may be sent different virtual map positioning data to provide the group XR experience.
