Touch Terminal Activation Through Pointer-Triggered Remote Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing input devices between computers and touch terminals, such as tablets or smartphones, require manual user interaction to unlock the touch terminal, which detracts from the user experience and reduces the value of device sharing.
Innovation Solution
A method and device that allow a first terminal to be activated from a second terminal via a communication network, using a detection zone on the second terminal's screen to trigger an unlocking command without manual user interaction, employing encryption keys for security and optimizing ergonomics by anticipating the unlock sequence based on pointer movement speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual unlocking action is required on the touch terminal, then security is maintained, but user experience deteriorates and the value of device sharing is reduced
Solution Approach 1:
The system performs preliminary association between the first terminal and second terminal in advance. When the pointer reaches the detection zone, the unlocking command is already prepared and can be transmitted immediately, eliminating the need for manual unlocking actions while maintaining security through pre-established cryptographic relationships.
Solution Approach 2:
The touch terminal automatically detects the pointer position in the detection zone and triggers the unlocking sequence without requiring user intervention. The system serves itself by monitoring input device actions and autonomously initiating the unlock process when conditions are met.
2Use of energy by moving object
If the terminal is in power-saving mode, then energy consumption is reduced, but the terminal cannot be controlled from shared input devices
Solution Approach 1:
The association between terminals is established in advance when both are active. This pre-configured relationship allows the terminal to be quickly reactivated from power-saving mode when needed, as the cryptographic keys and communication channels are already prepared, reducing both energy waste and activation delay.
3Reliability
If encryption keys are used for security, then terminal activation security is improved, but system complexity increases
Solution Approach 1:
The second terminal acts as an intermediary that holds and manages the cryptographic keys. Instead of each terminal managing its own complex key infrastructure, the trusted second terminal mediates the authentication process by verifying the first terminal's identity and transmitting the unlock command, simplifying the overall system architecture while maintaining strong security.

AI summary
The invention relates to a method of activating a first terminal from a second terminal, the first and second terminals being connected via a communication network, the method being such that it includes steps of associating the first terminal with the second terminal, detecting an action on an input device associated with the second terminal, and transmitting a notification to the first terminal, the notification including at least one command suitable for authorizing the unlocking of the first terminal.
