Multi-Device Unlocking via Virtual Line Arrangement Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the inconvenience of needing to individually unlock multiple smart devices, which can be time-consuming and inefficient, especially when trying to access multiple devices simultaneously.
Innovation Solution
A method and system for calculating arrangement data between devices, including distance and angle, to enable secure unlocking and data sharing by drawing virtual straight lines on touch screens, which can be used as a security key and to display content across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user unlocks multiple smart devices individually using traditional methods, then each device can be accessed securely, but the time required to access multiple devices increases significantly
Solution Approach 1:
The patent merges multiple device unlocking operations into a single unified action. By calculating arrangement data (distance and angle) between multiple devices and the user's smartphone, the system enables simultaneous unlocking of multiple devices through one gesture, combining what would traditionally require separate unlocking actions into a single efficient operation
Solution Approach 2:
The system performs preliminary calculation of arrangement data between devices before the actual unlocking is needed. By pre-establishing the spatial relationships and validation criteria, the system prepares the unlocking conditions in advance, allowing rapid execution when the user performs the unlocking gesture without requiring real-time complex calculations
2Ease of operation
If traditional individual unlocking methods are used for multiple devices, then each device maintains independent security control, but user convenience and efficiency decrease
Solution Approach 1:
The patent combines multiple device access operations into a single unified gesture. The user performs one unlocking action that simultaneously accesses multiple devices based on their calculated arrangement data, merging what would traditionally be separate operations into a single efficient action that improves both ease of operation and productivity
Solution Approach 2:
The system creates a universal unlocking mechanism that works across multiple different devices simultaneously. The arrangement data calculation enables a single gesture to function as a multi-device key, allowing one operation to perform the function of unlocking multiple different devices, thereby improving operational efficiency
3Adaptability or versatility
If virtual straight lines are drawn on touch screens to calculate arrangement data, then a unified security key can be created for multiple devices, but the system complexity increases
Solution Approach 1:
The system uses the user's smartphone as a reference copy to establish arrangement data for other devices. By calculating distance and angle relationships relative to the smartphone's position and orientation, the system creates a template that can be applied to multiple devices, enabling multi-device compatibility through a standardized reference framework that manages system complexity

AI summary
A method for calculating arrangement data between devices includes: receiving an input of a first point on a display of a first device; receiving an input of a second point on a display of a second device; and calculating arrangement data between the first device and the second device based on data of a virtual straight line connecting the first point and the second point, and the arrangement data include a distance between the first device and the second device and an angle between the first device and the second device.
