Solution Overview

Problem

Current augmented reality technologies do not effectively display and navigate image data together with associated virtual information, particularly in relation to the location where the image data are recorded, limiting user experience and information accessibility.

Innovation Solution

A digital device method that records image data along with position and direction information, allowing for the display of image data with augmented reality information and navigation of virtual information based on the recorded location, using sensors like GPS and gyroscope to provide real-time updates and orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If augmented reality information is displayed together with image data, then information accessibility is improved, but device complexity increases

Engineering Contradiction:
Improveinformation accessibilityVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides the display content into distinct segments: original image data and augmented reality information. The processor separately handles image data from storage medium and AR information from communication interface, then composite them. This segmentation allows independent processing and display of each type of information, improving accessibility without overwhelming the device architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a communication interface as an intermediary component that receives AR information from external sources (servers, other devices) and a processor that acts as a mediator to composite this AR information with image data. This intermediary structure manages the complexity by creating dedicated data flow paths between external sources and the display unit.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If navigation of augmented reality information is enabled based on recorded location, then user experience is improved, but measurement precision requirements increase

Engineering Contradiction:
Improveuser experienceVSAvoidposition information accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent performs preliminary action by storing position information and direction information at the time of image recording. This pre-captured spatial data serves as a reference for subsequent AR information navigation, allowing the system to reconstruct the original viewing context without requiring high-precision real-time measurements during the display phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a copy of the spatial context by storing position and direction information when images are recorded. This copied spatial data is then used to navigate and orient AR information, allowing the system to reproduce the original recording perspective without requiring the device to be physically transported to the recorded location, thereby reducing precision demands.

Inventive Principle:
Principle #26Copying

3Loss of time

If real-time augmented reality information is provided, then information freshness is improved, but use of energy increases

Engineering Contradiction:
Improveinformation freshnessVSAvoidenergy consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by receiving AR information at scheduled intervals through the communication interface rather than continuously. The processor composites and displays this periodically updated AR information with stored image data, providing timely information updates while allowing the system to enter lower-power states between communication cycles, thus balancing freshness with energy conservation.

Inventive Principle:
Principle #19Periodic action
