Ring Display Position Adjustment for Rotational Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring-shaped display devices with curved surfaces face challenges in maintaining visibility of information as they rotate, as desired information may not remain at the intended position due to changes in the relative position of the display region with respect to the viewer's eye.
Innovation Solution
A ring-shaped display device equipped with a sensing unit, such as an acceleration sensor, that senses positional information and adjusts the display position in real-time to counteract rotation, ensuring information remains easily visible by moving it in the opposite direction of rotation, thereby maintaining a consistent display orientation relative to the viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If information is arranged along the circumference of a ring-shaped display device, then the display device can display a variety of information, but information displayed on display regions at sides or outer peripheral surfaces cannot be easily seen
Solution Approach 1:
The display position is dynamically adjusted based on the detected rotation angle. When the display device rotates, the control unit calculates the new display position by adding the rotation angle to the original position, ensuring information remains visible on the front display region rather than fixed on the display device structure.
2Adaptability or versatility
If a ring-shaped display device rotates in circumferential direction, then the display device can be worn on wrist, but the relative position of information with respect to viewer's eye changes and desired information may not appear at intended position
Solution Approach 1:
The acceleration sensor continuously detects the rotation angle of the display device, providing feedback to the control unit. The control unit uses this feedback to calculate and adjust the display position in real-time, compensating for rotation and maintaining accurate information positioning relative to the viewer's eye.
3Device complexity
If display position is fixed on the display device, then the display structure is simple, but information visibility changes when the device rotates
Solution Approach 1:
The control unit acts as an intermediary between the fixed display structure and the rotating display device. It receives rotation data from the acceleration sensor and dynamically adjusts which information is displayed at which position, effectively decoupling the physical display structure from the logical information positioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures that information remains easily visible and accessible even when the display device rotates, reducing the risk of burn-in and extending the device's lifespan by optimizing display positioning and reducing power consumption.
Implementation Method 1
The sensing unit may include an acceleration sensor. The positional information of the display device may include rotational positional information based on rotation in a circumferential direction of the display device.

AI summary
A display position of an image is moved in accordance with positional information of a display device having a curved display surface. Displacement of a display device is sensed by a camera portion and an acceleration sensor, and the display position is determined in accordance with the displacement, so that the image is displayed in the display position. In the case where the display device rotates and the like, a desired piece of information can be displayed automatically in a display region that can be easily seen.
