Non-mirrored Text Preview in Mirrored Webcam Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video communication systems using laptops or external webcams suffer from low-quality video images due to basic camera capabilities, and there is a need for improved video preview and control during video communication sessions.
Innovation Solution
An electronic device with an image capturing device and a video image segmentation and control module (VISCM) that segments a video image into primary and secondary segments, allowing for a touchless action center with virtual interfaces to be presented, enabling touchless user interfacing and control during video communication sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If front facing cameras are utilized to operate as webcam, then video quality is improved, but the video preview is presented as a mirror image making text and objects difficult to interpret correctly
Solution Approach 1:
The video image is segmented into multiple regions: a first region containing the mirror image and a second region containing the non-mirrored image with correctly oriented text and objects. This segmentation allows users to view both the mirror image for self-monitoring and the non-mirrored image for correct text interpretation simultaneously.
Solution Approach 2:
The solution adds a spatial dimension by dividing the video display into multiple regions or quadrants. Instead of choosing between mirror and non-mirrored views, the system presents both views in different spatial locations within the same video feed, allowing users to access both perspectives without switching modes.
2Area of stationary object
If laptop or external webcam is used for video communication, then larger display is available, but video image quality deteriorates due to basic camera capabilities
Solution Approach 1:
The system enables a smartphone (typically used for mobile communication) to function as a high-quality webcam for laptop use. By utilizing the smartphone's superior camera capabilities through a video communication application, the system achieves high video quality on a larger laptop display, making the smartphone universally functional for both mobile and desktop video communication scenarios.
3Ease of operation
If traditional touchscreen interface is used for video control, then user interaction is simple, but touch gestures may be inaccurate or require physical contact with the device
Solution Approach 1:
The system replaces physical touchscreen contact with air gesture recognition. Users can control video functions by making gestures in the air above the device without physically touching the screen. The system detects and interprets these airborne gestures through sensors, substituting the mechanical touchscreen interface with a contactless gesture recognition system that maintains simplicity while improving accuracy.

AI summary
A method provides non-mirrored preview of text-based demonstration objects in a locally captured video stream. The method includes identifying a demonstration object within the video stream. The demonstration object contains content that is best when pre-viewed in a non-mirrored orientation. The method includes spatially segmenting the video image into two or more segments, including a demonstration object preview (DOP) segment that encompasses the defined area with the demonstration object and at least one second segment encompassing a remaining portion of the video image. The method includes presenting a preview of the video image on the display device with the remaining portion of the video image mirrored within the preview and at least the DOP segment presented without mirroring in a correct spatial location relative to the remaining portion of the video image. A person presenting the demonstration object receives a non-mirrored presentation preview of the demonstration object.
