Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems face challenges in seamlessly integrating virtual objects across different spaces within an AR environment, particularly in enhancing the reading experience for children by providing interactive and engaging holographic visual aids that transition smoothly between two-dimensional and three-dimensional spaces.
Innovation Solution
The technology allows virtual objects to interact and transition between different spaces within an AR environment by assigning them to specific spaces with physics constraints, using dual representations to detect interactions and employing space transition events, such as reaching boundaries or gaze detection, to move objects between two-dimensional and three-dimensional spaces, with holographic visual aids being used to enhance reading experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are integrated into AR environment, then reading engagement is improved, but spatial integration complexity increases
Solution Approach 1:
The patent segments the AR environment into multiple distinct spaces (2D book page space, 3D world space, and intermediate transition spaces). Each space has its own physics constraints and rendering rules, allowing virtual objects to be managed independently in different spatial contexts. This segmentation reduces integration complexity by localizing spatial management tasks while maintaining high engagement through diverse interactive environments.
Solution Approach 2:
The patent implements transitions between two-dimensional book page space and three-dimensional world space, adding dimensional flexibility to the AR reading experience. Virtual objects can exist in 2D context during reading and transition to 3D for interactive exploration, enhancing engagement while managing complexity through dimension-specific rendering pipelines and physics engines.
2Ease of operation
If virtual objects transition between spaces, then interactivity is improved, but detection precision requirements increase
Solution Approach 1:
The patent introduces intermediate transition spaces that act as mediators between 2D book page space and 3D world space. These intermediate zones buffer the transition process, allowing gradual transformation of virtual objects and reducing the precision demands on detection systems. The intermediary spaces provide a buffer zone where objects can be partially transformed and detected with lower precision requirements before fully transitioning to the target space.
Solution Approach 2:
The patent employs parameter changes during space transitions, including scaling, positioning, and physics constraint modifications. Virtual objects undergo controlled parameter transformations as they move between spaces, with the system adjusting detection thresholds and precision requirements dynamically based on the transition state. This allows high interactivity through smooth transitions while managing detection precision through adaptive parameter adjustment.
3Reliability
If dual representation is used for virtual objects, then interaction detection is improved, but computational load increases
Solution Approach 1:
The patent segments the dual representation into space-specific components: 2D representation for book page interactions and 3D representation for world space interactions. The system activates only the representation relevant to the current space, reducing computational load while maintaining reliable interaction detection. When a virtual object is in 2D space, only 2D detection algorithms run; when in 3D space, only 3D algorithms are active, eliminating redundant computations.
Solution Approach 2:
The patent implements dynamic switching between dual representations based on the virtual object's current space and interaction context. The system dynamically activates or deactivates specific representation components rather than maintaining both representations continuously active. This dynamic approach ensures reliable interaction detection in each space while significantly reducing computational load by processing only the necessary representation data at any given moment.

AI summary
A system for allowing a virtual object to interact with other virtual objects across different spaces within an augmented reality (AR) environment and to transition between the different spaces is described. An AR environment may include a plurality of spaces, each comprising a bounded area or volume within the AR environment. In one example, an AR environment may be associated with a three-dimensional world space and a two-dimensional object space corresponding with a page of a book within the AR environment. A virtual object within the AR environment may be assigned to the object space and transition from the two-dimensional object space to the three-dimensional world space upon the detection of a space transition event. In some cases, a dual representation of the virtual object may be used to detect interactions between the virtual object and other virtual objects in both the world space and the object space.
