Virtual Object Unfolding for Natural Augmented Reality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems, such as the game apparatus disclosed in Japanese Laid-Open Patent Publication No. 2006-260602, fail to create a natural augmented reality effect by suddenly displaying virtual objects in real space, disrupting the user's perception of the object's presence in the environment.
Innovation Solution
An information processing program that includes a computer-readable storage medium with features like photographed image data acquisition, virtual camera setting, object positioning, control mechanisms for moving and reshaping virtual objects, texture mapping, and display control to gradually reveal virtual objects within a real space, allowing them to appear as if they are unfolding from a closed shape into an open one, maintaining a natural augmented reality effect.

1Speed
If a virtual object is suddenly displayed on the screen when a game is started, then the game can begin quickly, but the natural augmented reality effect is spoiled and the user cannot feel as if the virtual object really exists in the real space
Solution Approach 1:
The virtual object is prepared in a closed shape state before being displayed. The system performs preliminary positioning and shape configuration so that when the object is finally displayed, it already has a natural appearance that blends with the real space, avoiding sudden appearance while maintaining quick game start
Solution Approach 2:
The virtual object's shape is dynamically changed from a closed shape to an opened shape after display. This dynamic transformation allows the object to reveal its contents gradually, creating a natural augmented reality effect where the user perceives the object as truly existing in the real space
2Device complexity
If a virtual object is displayed in a closed shape, then the initial display is simple, but the user cannot see the contents inside the virtual object
Solution Approach 1:
The virtual object is segmented into different shape states: a closed shape for initial display and an opened shape for revealing contents. This segmentation allows the system to maintain simplicity in the initial state while providing full visibility information when needed
Solution Approach 2:
The virtual object dynamically transforms from a closed shape to an opened shape, allowing the user to see internal contents such as game cards or other objects stored inside. This dynamic shape change provides information on demand without complicating the initial display
