Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Augmented and mixed reality devices struggle to prevent collisions between users and surrounding objects without interrupting the display of virtual objects, as users may not be aware of the position of virtual objects in real space, leading to potential collisions with objects or people.

Innovation Solution

An information processing system that includes a device for displaying virtual objects superimposed on real space, an acquirer to detect real objects, and a processor that moves virtual objects away from detected real objects within a predetermined range to avoid collisions without stopping the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display of virtual objects is stopped to avoid collisions with surrounding objects, then user safety is improved, but manipulation of virtual objects is interrupted

Engineering Contradiction:

Improveuser safetyVSAvoidmanipulation continuity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary detection of real objects and pre-calculates collision risk before the user interacts with virtual objects. By identifying potential hazards in advance and preparing avoidance strategies, the system prevents collisions without interrupting the user's manipulation workflow, thus maintaining both safety and productivity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary collision avoidance mechanism that mediates between the virtual object display and real-world environment. This intermediary layer detects real objects, calculates collision risks, and adjusts virtual object positions or provides warnings, allowing continuous manipulation while preventing harmful collisions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If virtual objects are displayed with high brightness and resolution to increase immersion, then user immersion is improved, but collision risk with surrounding objects increases

Engineering Contradiction:

Improveuser immersionVSAvoidcollision risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system implements real-time feedback by continuously detecting real objects in the user's environment and providing information about potential collisions. This feedback loop allows the system to maintain high-immersion virtual displays while warning users of real-world hazards, enabling them to adjust their behavior without reducing display quality

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary detection and risk assessment of real objects before collisions occur. By identifying hazardous objects in advance and notifying users or adjusting virtual display parameters, the system maintains high immersion while preventing collisions through advance warning rather than reducing display quality

Inventive Principle:

Principle #10Preliminary action

AI summary

An information processing system includes a device causing a user to see visual information in which a virtual object is superimposed onto information about a real space, an acquirer that acquires a position of a real object existing in the real space, and a processor configured to move the virtual object in a direction away from the real object in a case where the real object is positioned inside a predetermined range from the device.
