Mixed Reality Interference Reporting via Time-Filtered Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mixed reality systems face issues with excessive reporting of virtual object interference, particularly when noise or reduction in position and orientation estimation accuracy leads to unstable interference determination, resulting in frequent and unnecessary interference reports to the user, especially when using head-mounted displays.
Innovation Solution
An information processing apparatus that determines the positional relationship between virtual and target objects and reports interference only if the distance between them is less than a predetermined value, with a mechanism to prevent excessive reporting by waiting for a predetermined time to elapse since the last report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interference reporting is performed continuously without time filtering, then all interference events are reported to the user, but the user experiences information overload and excessive reporting frequency
Solution Approach 1:
The patent applies periodic action by introducing a time-based filtering mechanism that reports interference events only when they occur after a predetermined time interval has elapsed since the last report. This periodic reporting approach filters out continuous or frequent interference events that occur within the time threshold, thereby reducing excessive reporting frequency while maintaining detection accuracy for significant interference events.
2Measurement precision
If position and orientation estimation is performed with high sensitivity, then interference detection accuracy is improved, but noise causes unstable determination and false interference reports
Solution Approach 1:
The patent applies beforehand cushioning by implementing a time-based threshold mechanism that cushions against the harmful effects of noise-induced instability. By requiring that interference events persist beyond a predetermined time interval before triggering a report, the system filters out transient false positives caused by noise while maintaining sensitivity to genuine interference events, thus stabilizing interference determination.
3Object-generated harmful factors
If interference reporting is suppressed to reduce frequency, then user overload is prevented, but important interference events may be missed
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the reporting decision based on the time interval parameter between consecutive interference events. Instead of uniformly suppressing or reporting all interference events, the system changes the reporting parameter (time interval) to distinguish between significant events worth reporting and transient events to be filtered, thereby preventing information overload while maintaining detection of important interference events.

AI summary
An information processing apparatus that causes a display unit to display a three-dimensional space in which a first virtual object and a second object are present includes a determination unit that determines a positional relationship between the first virtual object and the second object in the three-dimensional space and a report unit that reports that a distance between the first virtual object and the second object is less than or equal to a predetermined value based on a determination result obtained by the determination unit.
