Portable Terminal Lock State Cancellation via Notice Object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable terminals struggle to remember the correspondence between operation scenes and gestures, leading to difficulties in canceling a lock state when they forget the correct gesture to return the touch panel to a normal operation.
Innovation Solution
A portable terminal with a display and touch panel that displays a lock object for canceling the lock state, featuring a storing module for notice information, a display processing module to show a notice object, a determining module to assess touch operations, and a performance module to perform functions corresponding to the notice object when the lock state is canceled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation scenes and gestures are registered, then the functionality of the portable terminal is improved, but the ease of operation deteriorates because users have to memorize the correspondence relationships
Solution Approach 1:
The system automatically displays the notice object indicating the current operation scene on the lock screen, allowing the device to inform the user of the active scene without requiring the user to memorize gesture-scene correspondences. This self-service information display resolves the contradiction by maintaining multiple functional scenes while eliminating the need for user memorization.
2Reliability
If a lock state is set to restrict touch operations, then the security of the portable terminal is improved, but the ease of operation deteriorates because users cannot easily return to normal operation
Solution Approach 1:
The notice object displayed on the lock screen serves as an intermediary element that mediates between the locked state and normal operation. By displaying the current operation scene information and enabling scene switching through simple touch operations on this notice object, the system maintains security while providing an intuitive path for users to restore normal operation without needing to remember complex gestures.
3Reliability
If the touch panel is in a halt condition, then the security of the portable terminal is improved, but the productivity deteriorates because the user cannot perform operations efficiently
Solution Approach 1:
The system performs preliminary action by displaying the notice object with current operation scene information before the user needs to switch scenes or cancel the lock state. This advance display of information allows users to quickly understand the current state and perform the next operation without delay, thus maintaining security while improving operational efficiency and productivity.

AI summary
A mobile phone 10 comprises a display 14, a touch panel 16, etc., and can set a lock state restricting performance of predetermined processing based on a touch operation. If the display 14 is turned ON when the lock state is set, a lock screen comprising a lock object (RO), etc. is displayed. If the lock screen is displayed when there is a new arrival mail, a mail object (Oa) is further displayed in the lock screen. At this time, if the lock object is dragged and dropped onto the mail object, a mail function is performed while the lock state is canceled. At this time, the new arrival mail is displayed on the display 14.
