Mobile Terminal Attitude-Based Lock Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals with locked states cannot easily determine if their intended movements are correctly input, leading to difficulties in canceling the lock function smoothly.
Innovation Solution
A mobile terminal equipped with a detector to sense attitude changes and a display to show a moving object on the screen, allowing users to set a predetermined area and change the object's position based on these changes, determining if the object is within the area to cancel the locked state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locked state is set to prevent accidental operations, then security and reliability are improved, but ease of operation deteriorates because users cannot easily determine if their intended movements are correctly input
Solution Approach 1:
The patent implements a feedback mechanism by displaying the moving object's real-time position on the screen based on the detector's output. This visual feedback allows users to confirm whether their movement inputs are correctly interpreted by the system, enabling them to adjust their cancellation operation accordingly. The feedback loop includes: detector detecting attitude → changer updating object position → displayer showing position → user confirming cancellation based on visual feedback.
2Ease of operation
If the moving object position is continuously updated based on attitude changes, then ease of operation is improved by providing visual confirmation, but device complexity increases due to additional components and processing
Solution Approach 1:
The patent applies multi-functionality by utilizing existing components for multiple purposes: the detector (accelerometer) serves both to detect attitude changes for the locked state function and to drive the moving object position updates for the cancellation function; the displayer serves both to show locked state information and to provide visual feedback during cancellation. This reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
3Ease of operation
If visual feedback is provided during cancellation operation, then ease of operation is improved, but use of energy increases due to continuous display updates
Solution Approach 1:
The patent implements periodic action by updating the moving object position based on attitude changes rather than continuous updates. The system monitors attitude changes and updates the display object position periodically when significant changes occur, rather than continuously refreshing the display. This approach maintains visual feedback for user confirmation while significantly reducing the frequency of display updates and associated energy consumption.

AI summary
A mobile phone apparatus is provided with an accelerometer for detecting an attitude and a display for displaying a moving object. Furthermore, a key locked state is set to the mobile phone apparatus for the purpose of preventing an operating error in the key. When an arbitrary key is operated in the key locked state, the moving object and a pocket object representing a predetermined area, etc. are displayed on the display. Then, when the moving object changes in position in correspondence with the change of the attitude of the mobile phone apparatus and is put into the pocket object, the key locked state is cancelled.
