AR Terminal Device 3D Virtual Object Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems can only perform two-dimensional operations on virtual objects, limiting intuitive position adjustment in three-dimensional spaces.
Innovation Solution
A terminal device equipped with an image-capturing unit, display unit, and object control unit that detects the movement of the device to adjust the position and orientation of virtual objects in real-time, allowing for three-dimensional manipulation within an augmented reality space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indicator-based operation is used for virtual object manipulation, then the operation interface is simple and clear, but only two-dimensional operations are possible and intuitive three-dimensional position adjustment is impossible
Solution Approach 1:
The patent transitions from two-dimensional indicator manipulation to three-dimensional device movement-based control. By detecting the movement of the terminal device in three-dimensional space (including depth, angle, and position changes), the system enables intuitive spatial manipulation of virtual objects, allowing users to adjust virtual object positions naturally by moving the device in corresponding directions.
2Ease of operation
If device movement detection is implemented for virtual object control, then intuitive three-dimensional position adjustment is enabled, but the device complexity increases
Solution Approach 1:
The terminal device uses its own movement and orientation changes to control the virtual object, eliminating the need for separate control inputs. The device's natural movement in space directly translates to virtual object manipulation, making the system self-descriptive and reducing the need for additional control mechanisms.
Solution Approach 2:
The patent replaces manual indicator manipulation with automatic detection of device movement through sensors (accelerometers, gyroscopes, etc.). The mechanical movement of the device is automatically converted into control signals for virtual object positioning, reducing manual intervention complexity.

AI summary
A terminal device according to one aspect presents an augmented reality space to a user. The terminal device includes: an image-capturing unit configured to capture an image of a real space; a display unit configured to display an augmented reality space image representing the augmented reality space including the real space captured by the image-capturing unit and a virtual object; a determination unit configured to determine at least a part of the virtual object as an operation target; and an object control unit configured to control an operation of the operation target in the augmented reality space. The object control unit detects a direction and an amount of a movement of the terminal device after the operation target is determined and moves the operation target based on the detected direction and amount of the movement of the terminal device.
