Dual-Screen Terminal Lighting Control via Touch Region Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen terminals struggle to accurately determine which screen a user expects to be lit, leading to poor user experience due to incorrect lighting and the need for additional user operations.
Innovation Solution
The terminal detects the quantity of touch regions on each screen and uses this information, along with camera detection and sensing apparatuses, to determine which screen to light, ensuring the correct screen is illuminated based on user interaction and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal uses acceleration sensor to detect screen orientation for lighting, then the lighting function can be activated, but the terminal cannot accurately determine which screen the user expects to light when the user lies on back or side
Solution Approach 1:
The patent segments the detection task by combining multiple sensors (acceleration sensor, touch screen detector, camera) to collectively determine screen orientation and user position, rather than relying on a single sensor that cannot accurately identify the intended screen when the user lies on back or side
Solution Approach 2:
The patent introduces touch screen touch detection as an intermediary method to determine user position. When the user touches the screen, the system can identify which screen is being touched and light that screen, bypassing the ambiguity of acceleration sensor data alone
2Reliability
If the terminal lights the screen detected as upward by acceleration sensor, then the lighting function works in normal orientation, but it lights the wrong screen when the user lies on back or side
Solution Approach 1:
The patent uses touch screen touch detection as feedback to verify and correct the screen selection. When the user touches a screen, the system receives feedback about which screen the user intends to use, and adjusts the lighting decision accordingly, ensuring the correct screen is lit even when the user lies on back or side
Solution Approach 2:
The patent performs preliminary detection using multiple sensors (acceleration sensor, touch detector, camera) before lighting the screen, to pre-determine which screen the user expects to light, avoiding the need for users to perform additional operations to correct wrong screen lighting
3Measurement precision
If the terminal requires multiple operations via switching button to light the expected screen, then the correct screen can be lit, but user experience deteriorates due to additional operation steps
Solution Approach 1:
The patent enables the terminal to automatically identify and light the intended screen through self-service detection mechanisms (touch detection, camera detection, acceleration sensor fusion), eliminating the need for users to manually operate switching buttons to select which screen to light
Solution Approach 2:
The terminal performs preliminary detection and determination of the intended screen before the user needs to interact with it, so that when the user wants to light a screen, the terminal has already identified which screen the user expects and can light it immediately without requiring additional user operations

AI summary
The present invention discloses a screen lighting method for a dual-screen terminal and a terminal. In this method, after detecting an operation performed by a user to trigger lighting of a screen, the terminal detects a quantity of touch regions on a first screen of the terminal and a quantity of touch regions on a second screen of the terminal, and the terminal lights a screen with a smaller quantity of touch regions. By analyzing a gesture of handholding the terminal by the user, a generality between a touch status of a screen that the user expects the terminal to light and a touch status of a currently unused screen is found. Therefore, the screen that the user expects the terminal to light can be determined relatively accurately based on the touch statuses of the two screens.
