AR Object Editing via Provisional Tablet View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of editing augmented reality (AR) objects is hindered when a user wearing a wearable terminal moves, causing the display range on a tablet terminal to change, making it difficult to accurately add annotations to objects.
Innovation Solution
An augmented reality processing system that uses a head-mounted display (HMD) and a tablet terminal connected via a communication network, sharing a world coordinate system based on real-space GPS, allowing the HMD to transmit AR object information to the tablet for editing, where the tablet displays a provisional AR object for editing, and reflects the edits back to the HMD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user wears the wearable terminal and moves, then the AR object can be displayed in the real space, but the display range on the tablet terminal changes moment by moment making annotation addition difficult
Solution Approach 1:
The patent creates a copy of the AR object as a provisional AR object on the tablet terminal. This copy maintains its position and properties independently of the wearable terminal's movement, allowing the user to edit annotations on the stationary tablet display without the object disappearing or moving.
Solution Approach 2:
The provisional AR object acts as an intermediary between the AR object in real space and the user's annotation input. It translates edits made on the tablet into modifications of the original AR object, bridging the gap between the moving wearable terminal and the stationary editing interface.
2Ease of operation
If the user focuses on the tablet terminal to add annotation, then the annotation can be added, but the wearable terminal is displaced from the object direction causing the object to not be displayed
Solution Approach 1:
By creating a provisional copy of the AR object on the tablet, the system allows the user to focus on the tablet for editing while the original AR object continues to be displayed reliably on the wearable terminal's head-mounted display, independent of tablet interaction.
Solution Approach 2:
The system segments the AR object into two independent instances: one displayed on the wearable terminal for real-space navigation and another provisional copy on the tablet for editing. This segmentation allows each to function independently without interfering with the other's reliability.
3Adaptability or versatility
If the display range changes moment by moment, then the AR object can track user movement, but the work of adding annotation becomes inefficient
Solution Approach 1:
The provisional copy on the tablet maintains a fixed display position regardless of movement, allowing efficient annotation editing. After editing, the changes are reflected back to the original AR object, achieving both adaptability and efficiency.
Solution Approach 2:
The system performs preliminary action by creating the provisional AR object before editing begins. This preliminary copy serves as a stable working space that doesn't change with movement, enabling efficient annotation addition without continuous adjustment.

AI summary
An augmented reality processing system transmits information regarding an augmented reality object (ARO) arranged in a virtual space on the basis of a world-coordinate-system from an information display device to an information processing device. The information processing device arranges a provisional ARO on the basis of the received information about the ARO in a work space on the basis of a terminal-coordinate-system with the information processing device as a reference and displays the provisional ARO on a display of the information processing device, and accepts an edit operation for the displayed provisional ARO and transmits the same to the information display device. The information display device reflects the content of the edit operation in the ARO arranged in the virtual space on the basis of the world-coordinate-system and displays the ARO, on the basis of the received information regarding the edit operation for the provisional ARO.
