Expandable Display Antenna Positioning for Accurate AR Anchors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flexible display devices, changes in the size of the display screen due to deformation affect the accurate positioning and posture of anchors, leading to incorrect display of augmented reality content.
Innovation Solution
An electronic device with a movable housing, expandable or retractable display, and an antenna system that estimates real-time coordinate values of the anchor's position and posture using phase offset values from lookup tables and sensor data, including ultra-wideband antennas for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen size is changed in flexible display devices, then the adaptability and versatility of the device is improved, but the measurement precision of anchor position and posture coordinate values deteriorates
Solution Approach 1:
The patent applies dynamics by making the housing movable relative to itself, creating variable display configurations. The housing includes a first housing and a second housing that can move relative to each other, enabling the display to transition between different sizes and shapes while maintaining accurate AR content positioning through real-time coordinate estimation adjustments.
2Adaptability or versatility
If the housing is made movable to enable display expansion or retraction, then the adaptability of the device is improved, but the device complexity increases
Solution Approach 1:
The patent merges the first housing and second housing into a single integrated movable housing structure. The housing includes both housings that can move relative to each other, combining multiple functions (display, AR positioning, movement mechanism) into one unified structure, thereby reducing overall device complexity while maintaining adaptability.
3Reliability
If real-time estimation of anchor position and posture is performed, then the reliability of AR content placement is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing the coordinate relationship between the antenna and camera in a reference state. The processor is configured to obtain information on a first position between the antenna and anchor, and information on position change between the antenna and camera, then estimate the second position based on these pre-established relationships, reducing real-time computational burden while maintaining accuracy.
