Rotatable Display Content Orientation Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in maintaining focused gaze while viewing content on display devices that require rotation, as the content and display rotate together, disrupting the viewing experience.
Innovation Solution
A method and device that control a rotatable display to maintain the orientation of content elements opposite to the display's rotation direction, ensuring the content's arrangement remains fixed while the display rotates, and includes features like fading out and fading in of elements to enhance the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is rotated to view horizontal or vertical content, then the content can be displayed in the correct orientation, but the user cannot maintain a focused gaze because the content rotates together with the display
Solution Approach 1:
The patent segments the rotation operation into two independent parts: the display hardware rotation and the content graphical rotation. The display can rotate to accommodate different content orientations, while the content itself rotates in the opposite direction to maintain its visual orientation relative to the user. This segmentation allows both display adaptability and gaze stability to be achieved simultaneously.
Solution Approach 2:
The patent applies inversion by rotating the content in the opposite direction to the display rotation. When the display rotates clockwise, the content rotates counter-clockwise by the same angle, effectively canceling out the rotational effect on the user's view. This inverse rotation maintains content orientation stability while allowing display orientation flexibility.
2Adaptability or versatility
If the content rotates together with the display, then the display can be rotated for different content orientations, but the user experience is disrupted and continuous viewing is not possible
Solution Approach 1:
The patent implements dynamic rotation control where the content rotation angle is dynamically adjusted based on the display rotation angle. The system continuously monitors display orientation changes and applies corresponding inverse rotations to the content, ensuring that the content remains visually stable relative to the user throughout the rotation process, thereby maintaining viewing experience continuity.
Solution Approach 2:
The patent creates a virtual copy of the content that rotates in opposition to the display rotation. Instead of rotating the original content directly, the system generates a transformed version of the content with adjusted rotation angles, allowing the display to rotate while the visual representation of the content maintains its orientation, thus preserving viewing continuity.

AI summary
A display device and a controlling method thereof are provided. The display device includes: displaying a plurality of objects on a rotatable display of the display device; based on an event occurring, rotating the rotatable display in a first direction; and based on the rotatable display being rotated in the first direction, rotating and displaying constituent elements included in the plurality of objects in a second direction, which is opposite to the first direction, while maintaining an arrangement of the plurality of objects.
