Controller-Based Unlocking for Locked Touchscreen Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience inconvenience when operating an electronic device to release a locking mode directly, especially when using a control device connected to the electronic device.
Innovation Solution
An electronic device equipped with a processor and a touch screen display that can store unlocking information and compare controller input signals with stored data to release the locking mode when a connected control device matches the unlocking information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking mode is set in the electronic device, then security is improved, but the ease of operation deteriorates when using a control device
Solution Approach 1:
The patent uses the control device as an intermediary to transfer the unlocking input from the electronic device's touch screen to the electronic device's locking mechanism. The control device receives input signals and transmits them to the electronic device, allowing users to unlock the electronic device without directly touching its touch screen, thus resolving the contradiction between maintaining security and improving ease of operation when using a control device.
2Reliability
If the user operates the electronic device directly to release locking mode, then the unlocking function is reliable, but the convenience deteriorates when a control device is connected
Solution Approach 1:
The control device serves as a mediator that captures user input and transmits it to the electronic device for authentication. This allows the unlocking function to remain reliable (verified through authentication) while improving convenience by enabling users to operate the electronic device through the control device rather than directly interacting with the electronic device's interface.
3Measurement precision
If the electronic device requires direct touch input for unlocking, then authentication accuracy is maintained, but usability deteriorates when using a control device
Solution Approach 1:
The control device acts as an intermediary that preserves authentication accuracy by transmitting input signals that can be validated against stored authentication data, while simultaneously improving usability by allowing users to interact with the electronic device through the control device's interface rather than requiring direct touch input on the electronic device's touch screen.

AI summary
An electronic device is disclosed. The electronic device comprises: a processor; a touch screen display electrically connected to the processor; an interface which is connected to a controller device and which transmits a first controller input signal received from the control device to the processor; a memory for storing first unlock information for releasing a lock mode of the electronic device on the basis of a touch input inputted through the touch screen display, wherein the memory stores instructions so that, when executed, the processor compares the first controller input signal with the first unlock information when the lock mode is set for the electronic device and the controller device is connected to the electronic device, and releases the lock mode of the electronic device when the first controller input signal matches the first unlock information. Other various embodiments identified through the specification are possible.
