Mobile Device Display Control for Context-Aware Wake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices face challenges in optimizing the information displayed when the screen is lit up again after a predetermined operation, often showing a static home screen instead of relevant information based on the user's current moving state.
Innovation Solution
A mobile electronic device with a display and a controller that determines the moving state and adjusts the information displayed accordingly, using sensors like acceleration, direction, and GPS to provide context-specific information such as train schedules, traffic updates, or calorie consumption when the screen is activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static home screen is always displayed when the display is lit up, then the device structure remains simple and easy to manufacture, but the information provided to users lacks relevance and adaptability to their current situation
Solution Approach 1:
The controller determines the moving state of the device in advance before the display is lit up, and pre-selects appropriate information to be displayed based on the detected state. This preliminary determination allows the system to provide context-relevant information without requiring complex real-time processing when the display activates.
Solution Approach 2:
The display content transitions from a static home screen to a dynamic, state-adaptive information system. The controller dynamically adjusts the displayed information based on the detected moving state (e.g., walking, running, stationary), making the system flexible and context-aware while maintaining relatively simple hardware architecture.
2Ease of operation
If the display always shows a home screen, then the ease of operation is maintained, but the usefulness and relevance of information provided deteriorates
Solution Approach 1:
The system incorporates feedback from motion sensors and other detection means to continuously monitor the user's moving state. This feedback loop enables the controller to automatically adjust the displayed information based on real-time detection results, ensuring the information remains relevant without requiring manual user input or complex interaction.
Solution Approach 2:
The device automatically determines its own moving state and selects appropriate information for display without requiring user intervention. The system serves itself by autonomously adapting the display content based on detected conditions, maintaining ease of operation while improving information relevance.

AI summary
In one aspect of the present invention, a mobile electronic device determines, when it is in a sleep state, a moving state of the mobile electronic device based on detection results of an acceleration sensor, a direction sensor, and a gyroscope. For example, the mobile electronic device determines whether a user is moving in a train, is moving on foot, or is moving in a car. The mobile electronic device displays information corresponding to the moving state (for example, in a train or a car, or on foot) on the display when returning from the sleep state to light up the display again.
