Dynamic Virtual Object Visibility Control in Augmented Reality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality systems, virtual objects are often excessively shielded by real objects, leading to reduced visibility and an uncomfortable user experience, particularly when multiple real objects obscure the virtual object's view.
Innovation Solution
An information processing apparatus and method that dynamically adjust display parameters based on the number of real objects hiding the virtual object, shifting its display position or transmittance to ensure visibility, using different display parameters in first and second states depending on the degree of occlusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shielding processing is executed to shield the virtual object by the real object, then depth perception is improved and uncomfortable feeling is reduced, but the virtual object becomes excessively shielded and cannot be viewed
Solution Approach 1:
The patent applies dynamics by making the shielding processing adjustable rather than fixed. The control unit dynamically switches between executing shielding processing and not executing it, based on detected user preferences. This allows the system to adapt the degree of shielding in real-time, resolving the contradiction between maintaining depth perception and ensuring virtual object visibility.
Solution Approach 2:
The patent changes the parameter of shielding intensity by introducing a selectable mode system. Users can choose between different shielding levels (first mode with shielding, second mode without shielding), which changes the display parameter of the virtual object. This parameter change allows the system to balance depth perception requirements against visibility requirements based on user preference.
2Reliability
If the virtual object is displayed with shielding processing, then depth cue is provided to the user, but the virtual object is hidden by real objects and cannot be viewed when positional relationship varies
Solution Approach 1:
The system dynamically adjusts the shielding behavior based on user-selected modes. When the user selects the second mode, the control unit determines not to execute shielding processing, making the virtual object always visible regardless of positional relationships with real objects. This dynamic adjustment resolves the contradiction between providing depth cues and ensuring ease of viewing.
Solution Approach 2:
The patent changes the display parameter of the virtual object based on the selected mode. In the second mode, the shielding parameter is adjusted to prevent occlusion by real objects, ensuring the virtual object remains visible. This parameter change allows the system to prioritize visibility while still providing depth information through other means.
3Reliability
If shielding processing is always executed, then depth perception is maintained, but user experience becomes uncomfortable when virtual object is excessively hidden
Solution Approach 1:
The patent makes the shielding processing dynamic and user-controllable. The control unit switches between executing and not executing shielding processing based on the user's selected mode. This dynamic approach allows users to maintain depth perception when needed (first mode) while avoiding uncomfortable excessive shielding when visibility is prioritized (second mode), thus resolving the contradiction.
Solution Approach 2:
The system incorporates user feedback through mode selection. Users can indicate their preference for shielding behavior, and the control unit adjusts its operation accordingly. This feedback mechanism allows the system to adapt to user needs, resolving the contradiction between maintaining depth perception and ensuring user comfort by allowing users to choose their preferred viewing experience.

AI summary
The present disclosure relates to an information processing apparatus and an information processing method that enable to ensure visibility when a virtual object is shielded. An information processing apparatus is provided that includes a display control unit that controls a display so as to display a virtual object by using a first display parameter in a first state where it is determined that the virtual object displayed by the display is hidden by at least one real object as viewed from a first user of the display and display the virtual object by using a second display parameter different from the first display parameter in a second state where it is determined that the virtual object is hidden by real objects more than that in the first state as viewed from the first user.
