Solution Overview
Problem
Existing virtual and holographic user interfaces that use optical elements to deform virtual images for user input can create disorienting effects due to mechanical motion, disrupting the user's perception when trying to interact with the image.
Innovation Solution
A user interface system that controls a display device to adapt virtual images in response to user input, eliminating the need for mechanical motion of optical elements, allowing for more versatile and intuitive interaction by scaling, distorting, or displacing the image within a constant image plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical motion of optical elements is used to deform virtual image, then user input detection is enabled, but user perception is disrupted and disoriented
Solution Approach 1:
The patent replaces the mechanical motion system (moving optical elements) with a graphical adaptation system. The display device dynamically modifies the visual characteristics of the virtual image (scaling, distortion, displacement) in response to detected user gestures, eliminating mechanical components while maintaining input detection capability and preserving perceptual stability.
Solution Approach 2:
The patent changes the parameters of the virtual image display (size, shape, position within image plane) based on detected user gestures. Instead of moving physical components, the system adjusts graphical parameters of the virtual image to provide feedback and enable interaction, resolving the contradiction between enabling input and maintaining perceptual stability.
2Adaptability or versatility
If optical element is moved to respond to user input, then interaction capability is improved, but image plane position changes causing disorientation
Solution Approach 1:
The patent separates the interaction functionality from the image plane positioning. User gesture detection and virtual image adaptation are decoupled from the physical/optical structure that defines the image plane. This allows the virtual image to be adaptively modified for interaction while the image plane remains stationary, preventing disorientation.
Solution Approach 2:
The patent creates a virtual copy of the interaction experience by graphically adapting the virtual image appearance rather than moving physical optical elements. The display device generates adapted visual representations that simulate interaction feedback while maintaining the stable image plane position, effectively copying the interaction effect without the disorienting side effects.
3Ease of operation
If sensitive mechanical components are used for virtual image deformation, then user input response is achieved, but device complexity increases
Solution Approach 1:
The patent eliminates sensitive mechanical components by substituting them with a software-based graphical adaptation system. The display device, controlled by processing unit, directly modifies virtual image parameters in response to detected gestures, achieving user input response without mechanical deformation mechanisms.
