3D Virtual Object Orientation for Natural AR Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with augmented and virtual reality environments are cumbersome, inefficient, and place a significant cognitive burden on users, requiring multiple inputs and manual adjustments to orient virtual objects, which wastes energy and detracts from the user experience.
Innovation Solution
The system automatically updates the orientation of virtual objects in a three-dimensional environment based on the user's viewpoint, modifies the appearance of real objects between the user and virtual objects, and selects user locations to enhance natural and efficient interaction, reducing the need for manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual methods are used to orient and manipulate virtual objects in augmented reality environments, then users have direct control over object positioning, but the cognitive burden increases and interaction efficiency decreases
Solution Approach 1:
The system automatically orients virtual objects to face the user based on detected head position and gaze direction, eliminating the need for manual rotation controls. The virtual object serves itself by autonomously adjusting its orientation to match the user's natural viewing direction, thereby simplifying interaction while maintaining precise control.
Solution Approach 2:
The system pre-positions and pre-orients virtual objects based on predicted user intent and head movement patterns before the user actually looks at them. This anticipatory adjustment reduces the cognitive load by having objects already in the desired state when the user focuses on them, rather than requiring the user to manually adjust them after placement.
2Productivity
If multiple input steps are required to achieve desired outcomes in augmented reality, then precise control is achieved, but energy consumption increases and interaction time is extended
Solution Approach 1:
The system maintains continuous tracking of head position and gaze direction to dynamically adjust virtual object orientation without requiring discrete input steps. This continuous adjustment mechanism eliminates the need for repeated manual interventions, thereby speeding up interaction and reducing the cumulative energy consumption associated with multiple input processing cycles.
Solution Approach 2:
The patent extracts and removes unnecessary intermediate input steps from the interaction sequence. By directly mapping head gaze direction to virtual object orientation, the system eliminates intermediate menu selections, rotation sliders, and confirmation steps, thereby streamlining the interaction path and reducing both time and energy expenditure.
3Adaptability or versatility
If virtual objects are placed in three-dimensional space, then spatial immersion is enhanced, but the complexity of locating and manipulating them increases
Solution Approach 1:
The system provides continuous visual feedback by rendering virtual objects with clear spatial cues and maintaining their orientation to face the user's gaze direction. This feedback mechanism helps users easily locate and track virtual objects in three-dimensional space by ensuring they always present their front surface to the user, making them visually identifiable and reducing the cognitive effort required to determine their orientation and position.
