Virtual Object Provision via Partial Condition Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality technologies fail to effectively provide virtual objects when changes in conditions, such as location or image, do not fully match predefined criteria, leading to incomplete or absent virtual object display.
Innovation Solution
An electronic device and method that compare received conditions to stored condition sets, providing a partially matching virtual object when no full match is found, allowing for diverse and individualized information display even with incomplete condition satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If strict condition matching is used for virtual object provision, then matching precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent applies partial action by introducing a partial matching mechanism that provides virtual objects even when not all conditions are satisfied. The system calculates a matching degree based on satisfied conditions and provides virtual objects when the degree exceeds a threshold, rather than requiring complete condition satisfaction. This resolves the contradiction by allowing adaptability to improve while maintaining acceptable matching precision through the threshold mechanism.
Solution Approach 2:
The patent changes the parameter of condition matching from binary (match/no match) to a continuous matching degree parameter. By calculating the proportion of satisfied conditions and using this as a continuous variable, the system can flexibly adjust virtual object provision based on the degree of match, thereby improving adaptability while preserving matching precision through configurable thresholds.
2Adaptability or versatility
If partial matching is implemented, then adaptability is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent implements feedback by calculating the matching degree and comparing it against a predetermined threshold. This feedback mechanism ensures that partial matching only occurs when the degree of match is sufficient, thereby maintaining manufacturing precision while improving adaptability. The threshold acts as a control parameter that prevents excessive relaxation of matching criteria.
3Reliability
If complete condition satisfaction is required, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies partial action by allowing virtual objects to be provided when a subset of conditions is satisfied, rather than requiring complete satisfaction. This improves ease of operation by making virtual object display more accessible, while reliability is maintained through the threshold mechanism that ensures sufficient condition satisfaction before provision.

AI summary
An electronic device and method for providing a virtual object are disclosed, including a processor and memory storing program instructions executable by the processor to implement the method, which includes receiving a request for a virtual object including a plurality of present conditions, searching a database for the virtual object by comparing the received plurality of present conditions to a plurality of condition sets, each set associated with at least one virtual object stored in the database; and when none of the plurality of condition sets matches all of the received plurality of present conditions, detecting a partially matching condition set matching at least one of the received plurality of present conditions and providing a partially matching virtual object corresponding to the partially matching condition set.
