Mobile Terminal Lock Screen Control for Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals require users to perform unlocking operations on a lock screen to give execution instructions to an image processing apparatus, resulting in unnecessary time and effort.
Innovation Solution
A mobile terminal that detects an image processing apparatus capable of wireless communication and displays a lock screen with an execution instruction button, allowing users to control the apparatus without unlocking the screen, thereby reducing the need for unlocking operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal requires unlocking operation to give execution instruction to image processing apparatus, then security of the terminal is improved, but user time and effort increase
Solution Approach 1:
The system performs preliminary authentication by detecting the image processing apparatus and preparing control instructions before the user needs to execute them. The control application pre-establishes the communication connection and validates the execution request, so that when the user provides input, the instruction can be executed immediately without requiring full screen unlocking.
2Reliability
If the lock screen restricts user input operations, then terminal security is improved, but ease of operation deteriorates
Solution Approach 1:
The control application segments the operation process into two distinct parts: authentication (handled by the lock screen security mechanism) and execution (handled by the control application). This allows the execution instruction to be processed independently of the full unlocking operation, enabling users to control the image processing apparatus while the lock screen remains displayed, thus improving ease of operation while maintaining security.
3Use of energy by moving object
If the mobile terminal switches from remote operation screen to lock screen, then power saving and security are improved, but productivity deteriorates
Solution Approach 1:
The control application provides self-service functionality by detecting when the user intends to execute a control instruction (through preliminary detection of the image processing apparatus and preparation of control data). The system automatically handles the execution process within the lock screen environment, eliminating the need for users to switch screens or perform additional unlocking operations, thus maintaining productivity while enabling power-saving lock screen mode.

AI summary
A mobile terminal that is capable of reducing time and effort of a user when the user gives an execution instruction to an image processing apparatus. A memory device stores a set of instructions. At least one processor executes the set of instructions to detect an image processing apparatus that performs wireless communication, display, on a display unit, a lock screen that accepts an unlocking operation by a user, display, on the display unit, a screen of a control application for controlling an image processing apparatus, after the unlocking operation is accepted, accept, while displaying the lock screen, an execution instruction for controlling the detected image processing apparatus, without accepting the unlocking operation by a user.
