AR Magnified Overlays Triggered by Virtual Marker Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) technologies lack the ability to provide magnified overlays that enhance user interaction and precision during close work activities such as dentistry and surgery, limiting the effectiveness of AR devices in these applications.
Innovation Solution
An AR eyewear device with cameras and displays that register virtual markers in the physical environment, allowing for the presentation of magnified overlays when the marker is within the field of view, and enabling adjustment through voice commands, gestures, or touchpad inputs, with optional pointer guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If magnified overlays are presented continuously, then detailed view of structures is provided, but user freedom of movement and natural viewing is restricted
Solution Approach 1:
The magnified overlay transitions from static continuous display to dynamic conditional display. The overlay appears only when the marker is detected within the field of view, and disappears when the marker moves out of view. This dynamic behavior allows users to maintain natural viewing freedom while obtaining detailed views precisely when needed for close work tasks.
2Measurement precision
If magnified overlay is always displayed, then detailed view of structures is provided, but the device complexity increases
Solution Approach 1:
Instead of continuous display, the magnified overlay is activated periodically or intermittently based on detection events. The system continuously monitors for marker presence but only activates the magnified overlay when the marker enters the field of view, reducing unnecessary processing and display updates while maintaining detailed view capability when required.
3Measurement precision
If marker detection is implemented, then precise interaction is enabled, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent introduces a virtual marker as an intermediary element that simplifies detection. Rather than detecting complex physical structures directly, the system detects the simplified virtual marker representation. This intermediary marker serves as a reliable detection target that enables precise marker location tracking while reducing the complexity of direct structure detection and measurement.

AI summary
A magnification application for use with augmented reality (AR) eyewear devices. The magnification application enables a user of an eyewear device to activate a magnification overlay on a display whenever a camera on the eyewear device detects that the field of view includes a registered virtual marker. The magnified overlay includes one or more frames of the captured video data, presented according to a predefined and configurable magnification power. A pointer including a vector and a visual tether guides the user toward the virtual marker. When the eyewear device location is near a perimeter associated with the virtual marker, the magnified overlay appears in a predefined and configurable frame on the display.
