Fixed Path Transitions for Virtual Object Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual universe environments, objects can be obstructed from view due to their positioning and characteristics, making it difficult for users to see them, especially when they are hidden behind other objects or due to lighting and color issues.
Innovation Solution
A computer-implemented method and apparatus for fixed path transitions, where tracking data identifies an avatar's location relative to an object's viewable field, and upon a trigger condition, a predefined fixed path is initiated, allowing the object to move along that path with specified speed and orientation, enhancing visibility by modifying its position and orientation.

Engineering Contradiction Analysis
1Quantity of substance
If objects are positioned in the virtual universe environment, then the virtual universe can be populated with diverse elements, but objects may be obstructed from view by other objects
Solution Approach 1:
The patent applies dynamics by making objects movable along predetermined paths. Instead of static positioning, objects are dynamically repositioned along fixed paths to transition from obstructed to visible states. The system determines when objects enter viewable fields and triggers path-based movement to ensure visibility while maintaining the ability to populate the virtual universe with diverse elements.
2Stability of the object's composition
If objects remain stationary, then the virtual universe environment remains stable, but objects hidden behind other objects cannot be viewed by users
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple predetermined paths for object movement. Before objects become obstructed, the system has already established alternative paths that can be activated. When an object is detected to be outside the viewable field, the system triggers movement along a predetermined path to bring the object into view, thus proactively preventing visibility issues rather than reacting to them.
3Difficulty of detecting and measuring
If objects move freely to improve visibility, then user viewing experience improves, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the virtual universe into multiple viewable fields and defining discrete predetermined paths for object movement. Instead of allowing completely free movement, the system segments motion into specific path options (first predetermined path, second predetermined path, etc.). This segmentation simplifies the control system by providing structured movement options while still achieving visibility improvement.

AI summary
Fixed path transitions in a virtual universe environment are provided. In one embodiment, tracking data that identifies a location of an avatar in relation to a range of an object in a virtual universe is received. The range comprises a viewable field. In response to the tracking data indicating an occurrence of a trigger condition associated with a fixed path rule, a fixed path defined by the fixed path rule is identified. A speed of movement and an orientation of the object associated with the fixed path rule is identified. Movement of the object along the fixed path defined by the fixed path rule is initiated. The object then moves along the fixed path at the identified speed and with the orientation associated with the fixed path rule.
