Camera-Display Positioning With Abstract Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for user positioning with front-facing cameras provide excessive visual feedback, disrupting alignment and causing anxiety, leading to lower success rates and slower processes in applications like face verification and recognition.
Innovation Solution
Systems and methods provide near real-time, abstracted visual feedback to guide users into optimal positions relative to the camera and display, using image processing techniques to extract essential edges and features, and display them in a way that avoids aesthetic distractions, ensuring quick and secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed visual feedback of the user's face is provided during positioning, then the user can see their image as it is being captured, but the user experiences anxiety and distraction from aesthetic considerations, disrupting alignment
Solution Approach 1:
The patent extracts only the essential alignment information from the full visual feedback, displaying abstracted geometric representations (lines, shapes, positions) rather than the complete facial image. This removes aesthetic distractions while preserving the functional information needed for proper positioning.
Solution Approach 2:
The patent uses color coding in the abstracted visual feedback to indicate alignment status and guide user positioning. Different colors represent different alignment states, providing intuitive visual guidance without showing the user's actual appearance that causes anxiety.
2Reliability
If the user is shown their own face during positioning, then they can monitor their appearance, but this induces anxiety and distraction leading to lower success rates
Solution Approach 1:
The patent removes the harmful aesthetic information (the user's actual facial appearance) from the visual feedback while retaining the functional alignment information. The abstracted display shows only geometric guides and positioning cues, eliminating the source of user anxiety.
Solution Approach 2:
The patent introduces an intermediary abstracted representation between the camera feed and the user. Instead of showing the raw facial image directly, the system processes it through abstraction algorithms that convert it into geometric guides, acting as a mediator that filters out harmful information while preserving useful alignment data.
3Ease of operation
If excessive visual feedback detail is provided to guide positioning, then the user has comprehensive information, but this disrupts the alignment process with extraneous detail
Solution Approach 1:
The patent extracts only the critical alignment parameters from the full visual feedback stream, displaying minimal essential information (geometric guides, position indicators) rather than comprehensive detailed feedback. This simplifies the visual interface while maintaining effective positioning guidance.
Solution Approach 2:
The patent segments the visual feedback into distinct functional elements (alignment guides, position indicators, boundary markers) rather than presenting a continuous detailed image. This segmentation allows the user to focus on specific positioning tasks without being overwhelmed by extraneous visual information.

AI summary
Systems, methods, and computer program products provide near real-time feedback to a user of a camera-enabled device to guide the user to capture self-imagery when the user is in a desired position with respect the camera and/or the display of the device. The desired position optimizes aspects of self-imagery that is captured for applications in which the imagery is not primarily intended for the user's consumption. One class of such applications includes applications that rely on illuminating the user's face with light from the device's display screen. The captured imagery is processed and displaced on the display.
