Rotatable Display UI Guidance for User Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in maintaining optimal user experience when switching between horizontal and vertical display modes, as main content may exceed the viewing angle, leading to interference in user interaction.
Innovation Solution
The electronic device includes a processor that identifies the user's gaze position and distance using a camera, determining the viewing angle area, and adjusts the display to provide a guide UI for optimal viewing angle adjustment, ensuring main content remains within the viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is rotated to vertical mode to provide vertical type content, then the display versatility is improved, but the viewing angle coverage deteriorates causing main content to exceed the user's viewing angle
Solution Approach 1:
The patent applies dynamics by making the UI layout adaptable and changeable based on real-time detection of user gaze position and distance. The interface dynamically adjusts element positions, sizes, and arrangements to ensure they remain within the user's viewing angle area, resolving the contradiction between display versatility and viewing angle coverage.
Solution Approach 2:
The patent changes UI parameters (position, size, arrangement of interface elements) based on detected viewing conditions. By adjusting these parameters according to the user's gaze position and distance, the system maintains optimal visibility while supporting both horizontal and vertical display modes.
2Quantity of substance
If the display area is increased to show more content, then the information quantity is improved, but the viewing angle coverage deteriorates causing interference in user interaction
Solution Approach 1:
The patent applies local quality by differentiating the treatment of UI elements based on their position relative to the user's viewing angle. Elements within the optimal viewing area are displayed with higher priority and appropriate sizing, while elements outside are adjusted or hidden, ensuring that frequently interacted content remains easily accessible.
Solution Approach 2:
The patent segments the display area into zones based on the user's viewing angle and interaction needs. By dividing the interface into priority levels and displaying critical interactive elements within the optimal viewing zone, the system maintains ease of operation while maximizing information presentation.
3Area of stationary object
If the UI elements are arranged to fill the entire display area, then the display area utilization is improved, but the viewing angle optimization deteriorates causing main content to be outside the threshold range
Solution Approach 1:
The patent uses dynamic adjustment of UI element positions and sizes based on real-time gaze detection. The system continuously monitors whether elements fall within the threshold viewing angle range and automatically repositions them, maintaining both high display area utilization and precise viewing angle optimization.

AI summary
An electronic device comprises: a display that is rotatable; a camera; a memory. The at least one processor is connected to the display, the camera, and the memory so as to control the electronic device to operate in one of a landscape mode and a portrait mode. The at least one processor is configured to identify a user's gaze position and a distance between the electronic device and the user, on the basis of a captured image obtained through the camera; identify a viewing angle area corresponding to a current display mode of the electronic device from among display areas of the display on the basis of the user's gaze position and the distance between the electronic device and the user; and control the display to display a guide UI to allow adjustment of the viewing angle area when the identified viewing angle area is outside viewing angle area.
