Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience eye fatigue while reading e-books on electronic devices due to difficulty in holding them steady, leading to a need for improved display adjustment methods.
Innovation Solution
An electronic device equipped with an acceleration sensor, storage unit, and processing unit that detects and compensates for movement by shifting display content to maintain a stable viewing position relative to the user's gaze, using displacement information to adjust the content's position on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users hold electronic devices steady while reading e-books, then reading comfort is improved, but it is difficult for users to hold devices completely steady
Solution Approach 1:
The patent applies dynamics by making the display content position adjustable and dynamic rather than fixed. The system automatically adjusts the display content position based on real-time device movement detected by the acceleration sensor, allowing the content to move with the device to maintain a stable viewing position relative to the user's gaze, thus resolving the contradiction between ease of operation and device stability
Solution Approach 2:
The patent implements feedback by using the acceleration sensor to continuously detect device movement and feed this information back to the processing unit, which then adjusts the display content position accordingly. This closed-loop feedback system compensates for user hand movements, maintaining reading comfort without requiring the user to hold the device perfectly steady
2Device complexity
If display content position is fixed, then device complexity is reduced, but eye fatigue increases due to device movement
Solution Approach 1:
The patent applies self-service by enabling the display system to automatically adjust content position based on device movement without requiring user intervention. The acceleration sensor continuously monitors device movement and the processing unit autonomously calculates and applies position corrections, making the system self-regulating and reducing eye fatigue while adding minimal complexity
Solution Approach 2:
The patent changes the parameter of display content position dynamically based on detected device movement. By adjusting the position parameter of displayed content in response to acceleration sensor data, the system compensates for device movement and reduces eye fatigue without requiring complex mechanical adjustments
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
The solution ensures that the content remains in the original position relative to the user's gaze, reducing eye fatigue by dynamically adjusting the display based on device movement, thereby enhancing reading comfort.

AI summary
An electronic device includes a display, an acceleration sensor, and a processing unit. The acceleration sensor detects displacement information of the electronic device. The processing unit compares the displacement information with an initial orientation information of the electronic device to determine directional movement of the electronic device. The processing unit shifts content of a display of the electronic device according to the directional movement.
