Foldable Screen Recording with Geometry-Aware Playback Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, particularly foldable devices, face challenges in accurately capturing and playing back screen content due to the lack of consideration for their geometric configuration during recording, leading to confusion and diminished user experience.
Innovation Solution
Incorporating folding angle information into the screen recording process, enabling devices to record and playback content with metadata that captures the device's deformation, and providing visual feedback to adjust the device's folding angle for accurate playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If foldable devices record screen content without capturing geometric configuration information, then the recording process is simple and fast, but the playback experience becomes confusing and inaccurate because users cannot understand the original device state
Solution Approach 1:
The system performs preliminary action by capturing and storing geometric configuration information (folding angle, device shape) at the moment of screen recording. This metadata is saved alongside the recorded content, enabling accurate playback representation without adding significant complexity to the recording process itself.
Solution Approach 2:
The patent introduces an intermediary element - visual indicators or overlays that represent the geometric configuration during playback. These visual cues act as mediators between the recorded content and the user, providing context about the original device state without requiring complex reconstruction of the physical device geometry.
2Loss of information
If foldable devices present screen content without visual indicators of geometric configuration, then the interface is clean and simple, but users cannot understand the original recording context and device state
Solution Approach 1:
The system applies local quality by placing visual indicators strategically within the user interface rather than overwhelming the entire display. These indicators provide geometric configuration information in localized areas (such as corners or borders) without disrupting the main content area, thus maintaining interface simplicity while conveying necessary context.
Solution Approach 2:
The patent utilizes color changes or visual styling variations to encode geometric configuration information. Different colors, opacity levels, or icon styles indicate different folding states or device geometries, allowing users to quickly understand the original recording context through intuitive visual cues without adding complex interface elements.
3Ease of operation
If foldable devices do not provide guidance for adjusting to original geometric configuration, then the interface remains simple, but users cannot achieve accurate playback experience matching the original recording conditions
Solution Approach 1:
The system implements feedback by providing real-time visual indicators that show the current device geometric configuration compared to the original recording configuration. When the device geometry matches the recorded state, the playback is optimized; when it differs, visual cues guide users to adjust the device to the correct configuration, creating a feedback loop that improves ease of operation.
Solution Approach 2:
The patent applies preliminary anti-action by proactively providing guidance indicators before users attempt playback. Rather than waiting for users to figure out the correct device configuration, the system preemptively displays instructions or visual cues that guide users to the proper geometric state, preventing playback issues before they occur.

AI summary
An electronic device with a deformable housing supports at least one display and includes sensors to detect the device's geometric configuration. Processors, operable with the sensors, present content with visual indicia that identify the deformed geometry at which the content was originally created, unless the current device configuration matches the original geometric configuration. The visual indicia may include instructions for adjusting the device to match the original geometry, enhancing the playback experience. The content's originating geometric configuration can be stored as metadata, allowing for accurate reconstruction during playback. This system addresses the challenges of screen recording and playback on foldable devices by incorporating the device's folding angle information into the screen recording process, thus ensuring playback reflects the original recording conditions.
