CGR Display Segmentation for Smooth Positional Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer-generated reality (CGR) technologies lack efficient methods for users to smoothly transition between locations within a CGR environment while maintaining contextual awareness of their movement, often resulting in disorienting changes in perspective and field of view.
Innovation Solution
The implementation of techniques that allow users to display a magnified portion of a CGR environment from a first position alongside an unmagnified portion, with adjustable magnification and field of view, enabling seamless transitions to new positions within the environment by incrementally changing the displayed field of view and position, while maintaining context through concurrent display of both magnified and unmagnified views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a user moves quickly to distant locations in a CGR environment, then movement efficiency is improved, but contextual awareness and orientation are lost
Solution Approach 1:
The display is segmented into multiple portions showing different magnification levels and field of view simultaneously. A first portion displays a magnified view with narrow field of view for detailed exploration, while a second portion displays an unmagnified view with wide field of view for contextual awareness. This segmentation allows users to maintain orientation while exploring details at any location in the CGR environment.
Solution Approach 2:
The system adds a dimensional layer to the display by showing multiple views (magnified and unmagnified) concurrently. Instead of switching between single views, the system presents a multi-dimensional display layout where users can see both detailed and contextual information simultaneously, preventing disorientation during rapid movement.
2Loss of information
If the field of view is increased to show more environment, then contextual awareness is improved, but detail visibility is reduced
Solution Approach 1:
The display area is divided into multiple segments: a first portion showing magnified content with narrow field of view for detailed visualization, and a second portion showing unmagnified content with wide field of view for contextual awareness. This segmentation resolves the trade-off by providing both detail and context simultaneously in different display regions.
Solution Approach 2:
Different portions of the display have different qualities: the first portion provides high magnification and narrow field of view optimized for detail, while the second portion provides low magnification and wide field of view optimized for context. Each region is optimized for its specific function, allowing users to access both detail and context without compromise.
3Measurement precision
If the magnification is increased to explore details, then detail visibility is improved, but field of view and orientation are reduced
Solution Approach 1:
The display is segmented to show a magnified portion and an unmagnified portion simultaneously. The magnified portion allows detailed exploration while the unmagnified portion maintains orientation and contextual awareness, eliminating the need to choose between detail and orientation.
Solution Approach 2:
The unmagnified display portion acts as an intermediary that maintains the user's sense of orientation and location in the CGR environment while the magnified portion provides detailed exploration. This intermediary view prevents complete disorientation that would occur with full magnification.
4Adaptability or versatility
If the display switches between different positions and magnifications, then exploration capability is improved, but continuity and smooth transitions are lost
Solution Approach 1:
The system maintains continuous display of both magnified and unmagnified portions throughout the transition process. As the user moves to new positions or adjusts magnification, both portions update continuously, providing smooth transitions without abrupt changes or loss of contextual information, thereby maintaining display stability and continuity.

AI summary
A magnified portion and an unmagnified portion of a computer-generated reality (CGR) environment are displayed from a first position. In response to receiving an input, a magnified portion of the CGR environment from a second position is displayed with a magnification less than that of the magnified portion of the CGR environment from the first position and a field of view greater than that of the magnified portion of the CGR environment from the first position. A first unmagnified portion of the CGR environment from a third position is displayed with a field of view greater than that of the magnified portion of the CGR environment from the second position. Then, a second unmagnified portion of the CGR environment from the third position is displayed with a field of view greater than that of the first unmagnified portion of the CGR environment from the third position.
