Event Container Lock Mode Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot intentionally select actions during the screen lock mode in mobile terminal devices, as they cannot predict whether an application corresponding to an event will be activated or a general menu will be displayed upon an unlock operation, and they are unaware of timeout occurrences.
Innovation Solution
A mobile terminal apparatus with a display unit, operation lock mode setting, event container display control, and a lock canceling operation unit that displays event containers and automatically activates application programs or shows a general menu based on user interactions, allowing users to preview event information while maintaining the screen lock mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screen lock mode is set to prevent unintended operations, then security is improved, but user ability to intentionally select actions during locked state deteriorates
Solution Approach 1:
The display screen is segmented into multiple independent event containers, each representing a different event or application. This allows the system to present multiple selectable options during lock mode, enabling users to intentionally choose specific actions while maintaining overall security through the locked state.
Solution Approach 2:
The event containers are designed to dynamically change state based on user interaction. When a user touches or hovers over an event container, it transitions to an active state with visual feedback, allowing users to intentionally select actions during lock mode while the system remains secured until a valid selection is made.
2Loss of information
If event information is displayed during lock mode, then user awareness of events is improved, but risk of unintended information disclosure deteriorates
Solution Approach 1:
Different event containers display different levels of information detail based on their activation state. Inactive containers show minimal information, while active containers (selected by user) reveal more detailed event information. This local differentiation allows user awareness without unintended disclosure.
Solution Approach 2:
The event container acts as an intermediary between the locked system and the user. It provides a controlled interface where users can preview event information through structured interactions (touch, hover) without fully accessing the underlying data, thus balancing awareness and security.
3Ease of operation
If multiple event containers are displayed during lock mode, then user control over action selection is improved, but interface complexity deteriorates
Solution Approach 1:
The interface is segmented into discrete, uniformly structured event containers rather than a complex monolithic display. Each container represents a single event with consistent visual characteristics, simplifying the overall interface structure while enabling multiple action selections.
Solution Approach 2:
The system displays only the essential information and controls needed for event selection during lock mode, avoiding excessive detail. Each event container shows sufficient information for recognition but omits unnecessary complexity, maintaining interface simplicity while providing user control.

AI summary
A mobile terminal apparatus including an operation lock mode setting unit that sets an operation lock mode; an event container display control unit that displays, when a predetermined event occurs, an event container indicating the occurred predetermined event on a display unit; an event container display change control unit that sets an event container between an active state and an inactive state; a lock canceling operation unit that cancels the operation lock mode; and a canceling operation handling control unit that, when an active-state event container is displayed on the display unit and the operation lock mode is canceled, performs automatic activation and display of an application program corresponding to the event of the active-state event container, and when all event containers on the display unit are in the inactive state and the operation lock mode is canceled, displays a predetermined display screen on the display unit.
