AR Marker Display Continuity via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Augmented Reality (AR) technologies face challenges in continuously displaying object data when the AR marker is no longer recognized, especially in scenarios where direct user operation of the terminal is limited, such as with wearable computers.
Innovation Solution
A display control method that transitions to a mode for continuous display of object data when the AR marker is recognized within a predetermined range for a certain time, allowing the data to be displayed even after the marker is no longer visible, using a recognition frame to facilitate user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If object data is displayed only when AR marker is recognized, then display accuracy is maintained, but usability deteriorates when direct terminal operation is difficult
Solution Approach 1:
The system performs preliminary recognition of the AR marker and stores the associated object data before the marker disappears. When the marker is no longer detected, the previously stored object data is displayed based on the last known position, allowing continuous display without requiring real-time marker recognition.
Solution Approach 2:
The patent introduces an intermediary mechanism (display control unit) that mediates between marker detection and object data display. This intermediary stores marker information and object data temporarily, enabling display continuity even when the marker is not currently detected, thus resolving the contradiction between maintaining accuracy and ensuring usability.
2Ease of operation
If AR marker recognition is required for continuous display, then display reliability is maintained, but ease of operation deteriorates in wearable device scenarios
Solution Approach 1:
The system performs preliminary detection and storage of AR marker information and associated object data before the marker disappears from view. This preliminary action enables the display to continue showing the stored object data even after the marker is no longer detected, extending the duration of display without requiring continuous marker recognition.
Solution Approach 2:
The patent implements continuity of useful action by maintaining object data display based on previously detected marker information. The display control unit continues to display the stored object data at the last known position even when the marker is not currently detected, ensuring uninterrupted useful display action without requiring continuous marker presence.
3Ease of operation
If object data is displayed without AR marker recognition, then ease of operation improves, but display precision deteriorates
Solution Approach 1:
The system performs preliminary and accurate detection of the AR marker while it is still visible, storing the precise position information and associated object data. This preliminary accurate detection ensures that when the marker disappears and display continues without real-time recognition, the displayed object data maintains high precision based on the previously captured accurate position information.
Data Source
AI summary
A display control method is executed by a computer. The display control method includes acquiring an image captured by a camera; displaying first object data corresponding to a reference object on a screen, when an image of the reference object is detected as being included in a first range in the captured image; and transitioning to a mode of continuously displaying the first object data corresponding to the reference object, when the image of the reference object is continuously detected as being included in a second range in the captured image for a predetermined time, even after the image of the reference object is no longer detected as being included in the first range in the captured image.
