Lock Screen Device Control via Swipe Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart home systems, controlling devices from a locked control device is cumbersome, requiring users to unlock and input passwords frequently, which complicates and delays device operation.
Innovation Solution
A method and device that allow users to receive and display device identifiers on the lock screen when touched along a predetermined path, enabling direct control of corresponding devices without unlocking, by acquiring and transmitting control instructions based on user account log-in status and network connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device enters lock status automatically after a preset time without operation, then information security and misoperation prevention are improved, but device control operation becomes complicated and time-consuming
Solution Approach 1:
The system performs preliminary action by displaying device identifiers on the lock screen in advance. When a user swipes upward from the bottom of the lock screen, the system proactively shows available devices without requiring full unlocking, allowing quick selection and control. This preliminary display of control options resolves the contradiction by maintaining security (device remains locked) while enabling fast operation (direct device selection from lock screen).
Solution Approach 2:
The lock screen serves as an intermediary interface between the locked state and full device access. By embedding device identifier display and selection functionality within the lock screen itself, the system creates a middle ground that provides both security (maintaining locked state) and operational efficiency (enabling device control without full unlock). This intermediary interface resolves the contradiction by allowing controlled access to device selection while preserving security constraints.
2Reliability
If the user inputs lock password frequently to control devices, then information security is maintained, but control time and operational efficiency are reduced
Solution Approach 1:
The system performs preliminary action by displaying device identifiers on the lock screen before requiring password input. The upward swipe gesture from the bottom of the lock screen triggers immediate display of available devices, allowing users to select and control devices without completing the full password authentication process. This preliminary display mechanism reduces control time while maintaining security by keeping the device in locked state.
Solution Approach 2:
The system inverts the traditional control flow by allowing device selection from the lock screen rather than requiring full unlock first. Instead of the sequence: unlock → select device → control, the system enables: select device from lock screen → control (with device remaining locked). This inverted approach reduces time loss while maintaining information security through the locked state.
Data Source
AI summary
A method, device and computer-readable medium for controlling a device are provided. The method includes: receiving an identifier display instruction, the identifier displaying instruction being generated when a lock screen of the control device is touched along a predetermined path; acquiring a device identifier of a corresponding controlled device according to log-in status of a user account on the control device; displaying the acquired device identifier of each controlled device on the lock screen; transmitting a control instruction to a controlled device corresponding to a selected device identifier after the selected device identifier is determined.
