Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positional misalignment of users in a virtual space due to environmental differences in position and posture measurement, leading to reduced realism and discomfort during communication.
Innovation Solution
A system that sets a shared virtual object as a base point for relative positional relationships between users, switching this object based on changes in user positions and virtual object locations to maintain accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specific virtual object is used as a fixed reference point for determining user display positions, then the positional relationship between users and that specific object can be maintained, but positional misalignment occurs with other virtual objects due to environmental measurement differences
Solution Approach 1:
The patent applies dynamics by making the reference object selection dynamic rather than fixed. The system automatically selects different shared virtual objects as reference points based on the current spatial configuration of users and objects. When users approach different virtual objects, the system switches the reference object accordingly, allowing accurate positional alignment adapt to different scenarios and objects in the virtual space.
Solution Approach 2:
The patent uses shared virtual objects as intermediary reference points to mediate the positional relationship between multiple users. Instead of directly measuring and aligning user positions, the system uses the shared virtual object as an intermediate reference frame, calculating relative positions with respect to this mediator object, which resolves measurement inconsistencies between different users' environments.
2Reliability
If absolute position coordinates are used to represent user locations in virtual space, then the position information is simple to transmit, but environmental differences cause misalignment when users view each other's positions
Solution Approach 1:
The patent introduces shared virtual objects as intermediary reference points to mediate the positional relationship between multiple users. Instead of directly measuring and aligning user positions, the system uses the shared virtual object as an intermediate reference frame, calculating relative positions with respect to this mediator object, which resolves measurement inconsistencies between different users' environments.
Solution Approach 2:
The patent changes the parameter representation from absolute coordinates to relative position information. Instead of transmitting and processing absolute position coordinates that are subject to environmental variations, the system transmits relative position data with respect to shared virtual objects, fundamentally changing the coordinate reference parameter to achieve environment-independent alignment.
3Adaptability or versatility
If the reference virtual object is fixed, then the system is simple to implement, but it cannot adapt when users move to different locations or when different virtual objects become relevant
Solution Approach 1:
The patent applies dynamics by making the reference object selection dynamic rather than fixed. The system automatically selects different shared virtual objects as reference points based on the current spatial configuration of users and objects. When users approach different virtual objects, the system switches the reference object accordingly, allowing accurate positional alignment adapt to different scenarios and objects in the virtual space.
Solution Approach 2:
The patent implements feedback by continuously monitoring the positions of users and virtual objects, and automatically adjusting the reference object selection based on this feedback. The system detects when users move or when different virtual objects enter the relevant range, and responds by switching the reference object to maintain optimal positional alignment, creating a closed-loop adaptive system.

AI summary
[Problem] A technology is provided capable of reducing the positional misalignment of a user in a virtual space as appropriate according to the situation. [Means of Solution] An information processing device is provided, including a control unit that: sets, as a shared object for a first user and a second user, a virtual object located within a first range whose base point is the first user in a virtual space, with the second user being present within a second range whose base point is the virtual object; transmits relative information indicating a relative positional relationship between the shared object and the first user to a user terminal associated with the second user; and switches the setting of the shared object in response to a change in at least any of a position of the first user, a position of the shared object, and a position of the second user in the virtual space.
