Mobile Screen Control via Wearable Palm Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile phones often need to manually power on and off the screen, which can be inconvenient and wasteful of battery life, especially when the device is intended for viewing or not in use.
Innovation Solution
A method and device combination that uses a mobile terminal, smart glasses, and a wearable device to detect the moving direction, screen orientation, and user's palm orientation to automatically power on the screen when the user intends to view it and power off when not needed, eliminating the need for manual button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen is manually powered on and off, then user control is maintained, but user convenience deteriorates and battery life is reduced due to unnecessary activations
Solution Approach 1:
The system enables automatic screen control by detecting user actions through sensors (accelerometer, gyroscope, camera) and autonomously powering on/off the screen without manual intervention, allowing the device to serve itself in managing screen state based on detected user intent
Solution Approach 2:
The patent replaces the mechanical button-pressing action with sensor-based detection systems (accelerometer, gyroscope, camera) that automatically detect user intent and trigger screen state changes, eliminating the need for manual mechanical operation
2Ease of operation
If automatic screen detection is implemented, then user convenience is improved, but device complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The patent makes existing sensors (accelerometer, gyroscope, camera) perform multiple functions - they detect not only their primary purposes but also user lifting actions and screen viewing intent, allowing one set of components to serve multiple detection purposes and reducing the need for additional dedicated sensors
3Measurement precision
If screen recognition instruction is sent to smart glasses, then determination accuracy is improved, but communication overhead increases
Solution Approach 1:
The system performs preliminary local detection using onboard sensors (accelerometer, gyroscope) to assess basic user intent before engaging smart glasses for confirmation, reducing the frequency of communication events and optimizing the balance between accuracy and communication overhead

AI summary
A screen control method is provided. The method includes: detecting, by a mobile terminal, a moving direction of the mobile terminal; detecting, by the mobile terminal, an orientation of a screen of the mobile terminal; receiving, by the mobile terminal, posture information sent by a wearable device, the posture information including a palm orientation of a user of the mobile terminal; sending, by the mobile terminal, a screen recognition instruction to smart glasses when each of the moving direction, the orientation of the screen, and the palm orientation is in a first direction; powering on the screen when screen recognition success information sent by the smart glasses is received; and powering off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second direction being different from the first direction.
