Display Control Apparatus Orientation Detection and Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems fail to easily allow users to view images in their desired direction, as they often require specific orientations or the use of cameras, and are limited by specific holding patterns of mobile terminals.
Innovation Solution
A display control apparatus with a display unit, orientation detection unit, and control unit that adjusts the display direction based on detected orientation and user input, allowing seamless switching between display objects without requiring specific operations or camera usage, and accommodating various holding forms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display control apparatus automatically adjusts display direction based on orientation detection, then the ease of operation is improved, but the device complexity increases due to the need for orientation detection units and control algorithms
Solution Approach 1:
The display control apparatus automatically detects its own orientation and adjusts the display direction without requiring user intervention. The orientation detection unit continuously monitors the apparatus orientation and the control unit automatically executes rotation control based on detected orientation changes, enabling the system to serve itself rather than requiring manual user input for each display adjustment.
Solution Approach 2:
The system implements a feedback loop where the orientation detection unit continuously monitors the actual orientation of the display apparatus, compares it with the expected orientation, and provides feedback to the control unit. The control unit then adjusts the display rotation based on this feedback, creating a closed-loop control system that automatically corrects display direction according to apparatus orientation.
2Device complexity
If the system requires specific holding patterns or camera usage to achieve desired display direction, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The orientation detection unit serves multiple functions: it detects apparatus orientation for display rotation control, determines appropriate display directions for different holding patterns, and enables the system to adapt to various usage scenarios without requiring separate mechanisms for each case. This multi-functional approach eliminates the need for separate camera systems or complex holding pattern requirements.
Solution Approach 2:
The patent replaces mechanical or manual orientation indication methods (such as physical orientation markers or camera-based face detection) with electronic orientation sensing. The orientation detection unit uses sensors to electronically detect apparatus orientation and converts this information into automatic display rotation control, eliminating the need for mechanical holding patterns or additional camera hardware.
3Adaptability or versatility
If the display direction changes automatically with orientation changes, then the adaptability is improved, but the loss of information increases when users need to switch between display objects
Solution Approach 1:
The control unit stores the previous display object information and rotation state before orientation changes occur. When the user switches display objects or performs a specific operation, the system retrieves the previously stored display object information and maintains the appropriate rotation state, ensuring that no information is lost during orientation transitions.
Solution Approach 2:
The system dynamically adjusts display rotation based on orientation changes while maintaining flexibility for user control. The control unit can switch between automatic rotation mode (for adaptability) and manual control mode (for information preservation), allowing the system to adapt to different user needs and prevent information loss when users intentionally switch display objects.

AI summary
In a case where an orientation of a display control apparatus is a first orientation, a first display object is displayed in a first direction; in a case where the orientation of the display control apparatus changes to a second orientation without a specific operation performed, the first display object is displayed in a second direction; when a switch instruction to switch a display object is given in this state, a second display object is displayed in the second direction; in a case where the orientation of the display control apparatus changes to the second orientation with the specific operation performed, the display direction of the first display object is not changed; and when the switch instruction is given in this state, the second display object is displayed in the first direction.
