Solution Overview

Problem

Existing video generation technologies struggle to maintain a natural background illusion when the vantage point changes during video recording or streaming, especially in mobile settings where the background may not be appealing or relevant, and users are constrained by physical obstacles or mobility issues.

Innovation Solution

An electronic system that includes an image capturing device and a controller to detect movement and automatically reposition a spherical background image, maintaining the illusion of a natural background by updating its virtual orientation and location relative to the foreground image, and enabling gesture-controlled background repositioning for spatially constrained users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed background image is used for video generation, then the background can be appealing or relevant, but the natural background illusion breaks when the vantage point changes

Engineering Contradiction:

Improvebackground appeal and relevanceVSAvoidnatural background illusion

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies dynamics by transitioning from a static background image to a dynamic spherical background that can be rotated and repositioned. The spherical background allows the system to adapt to changing vantage points by rotating the background content while maintaining the illusion of a natural environment, thus resolving the contradiction between background adaptability and illusion reliability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a third dimension by using a spherical background structure instead of a flat 2D background image. This spherical geometry allows the background to be viewed from multiple angles and rotated seamlessly, enabling the background to adapt to different vantage points while maintaining visual consistency and the natural illusion

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the vantage point changes during video recording, then mobile settings are enabled, but the fixed background becomes visibly artificial

Engineering Contradiction:

Improvemobile video recordingVSAvoidbackground realism

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts the spherical background based on the device's movement and vantage point changes. As the user moves the device during mobile recording, the spherical background rotates and repositions accordingly, maintaining the illusion of a natural environment while enabling flexible mobile operation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback from motion sensors and camera data to detect vantage point changes, then automatically adjusts the spherical background positioning and rotation to compensate for the movement, preventing the background from appearing artificial while maintaining ease of mobile operation

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If users are spatially constrained by physical obstacles, then mobility is limited, but background repositioning becomes difficult

Engineering Contradiction:

Improvebackground varietyVSAvoidbackground control

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides self-service by automatically detecting the user's spatial constraints through sensor data and autonomously repositioning and rotating the spherical background without requiring physical user movement. This allows users with limited mobility to still access diverse background views through automated gesture control

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical requirement of physical user movement with electronic and software-based solutions. Gesture recognition and automated background repositioning algorithms substitute for the mechanical action of the user physically moving to change background views, making background control accessible to spatially constrained users

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An electronic system, a method, and a computer program product generate a video recording or stream with spherical background effects for video generation with automatic gesture-control background positioning for a spatially constrained user. The method includes extracting a foreground image from an image stream of the field of view captured by the image capturing device. The method includes generating a composite image stream of the foreground image superimposed on the spherical background image. The method includes identifying, within the image stream, that the foreground image is in a physically constrained space defined by physical constraint(s) around at least a portion of a background of the foreground image. In response to identifying that the foreground image is in a physically constrained space, the method includes activating a gesture-controlled background repositioning feature of the electronic system to automatically rotate a spherical background image based on receipt of a gesture control input.
