Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In Augmented Reality applications, displaying associated information for multiple objects in real space can be challenging due to frequent changes in the object of interest as the user moves, making it difficult for the viewer to maintain a clear display of relevant information.

Innovation Solution

An information processing device that acquires multiple pictures of objects in real space, determines relative positional relationships between object images, and continues displaying associated information if these relationships remain substantially unchanged, allowing for adaptive and continuous display of relevant information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If associated information is displayed for multiple objects in real space, then the information completeness is improved, but the display stability deteriorates due to frequent changes in object of interest as user moves

Engineering Contradiction:

Improveinformation completenessVSAvoiddisplay stability

Core Design Contradiction:

Loss of informationVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic display switching based on relative positional relationships. The display controller dynamically determines which object's associated information to show by comparing positional relationships between objects in sequential pictures. When the relationship changes beyond a threshold, the display automatically switches between objects, providing both information completeness and display stability through adaptive dynamic control

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses feedback from positional relationship detection to control display switching. The display controller continuously monitors relative positional relationships between objects and uses this feedback to determine when to switch displayed information. This closed-loop feedback mechanism ensures the display remains stable while adapting to user movement and maintaining information completeness

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the display switches frequently between different objects, then the adaptability to user movement is improved, but the ease of viewing deteriorates due to frequent switching of displayed information

Engineering Contradiction:

Improveadaptability to user movementVSAvoidease of viewing

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts display content based on detected positional relationships, providing adaptability to user movement. However, it maintains ease of viewing by implementing a threshold-based switching mechanism that prevents excessive switching, thereby balancing adaptability with viewing comfort

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the display parameter (which object's information is shown) based on detected positional relationship parameters. By monitoring changes in relative position parameters and comparing them against thresholds, the system adapts to user movement while maintaining stable display periods, improving ease of viewing

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the system monitors positional relationships between multiple objects, then the adaptability to user movement is improved, but the device complexity increases

Engineering Contradiction:

Improveadaptability to user movementVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the monitoring task by focusing on relative positional relationships between pairs of objects rather than tracking all objects independently. The display controller segments the decision-making process into discrete switching events triggered by threshold-based relationship changes, reducing overall system complexity while maintaining adaptability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary threshold mechanism that mediates between raw positional relationship data and display switching decisions. This intermediary threshold layer simplifies the control logic by converting continuous positional changes into discrete switching events, reducing device complexity while preserving adaptability to user movement

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

According to one embodiment, an information processing device includes processing circuitry. The circuitry acquires a first picture including a first object and a second object; and acquires a second picture including the first object and an object different from the first object. The circuitry generates first data to display first associated information; and generates second data to display the first associated information superimposed onto the second picture in response to a change between a first positional relationship in the first picture and a second positional relationship in the second picture, the first positional relationship being a relative positional relationship between the first and second objects in the first picture. The second positional relationship is a relative positional relationship between the first object and the object different from the first object in the second picture.
