Mobile Terminal Icon Guidance via Camera Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face difficulties in quickly and easily accessing icon information due to limited input keys and display area, leading to cumbersome navigation through multiple hierarchies, especially for icons indicating predetermined states.
Innovation Solution
A mobile terminal configuration with a display unit, touch detection unit, and operation unit that enters a guidance display mode upon depressing a predetermined movable operation key, allowing for the display of a guidance screen related to any icon touched, enabling simple access to icon information without navigating through hierarchies and conserving power and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If icons are arranged on a wait screen and in application startup screens to indicate predetermined states and functions, then information can be displayed concisely, but it becomes difficult to reach the information of icons indicating predetermined states because they are located in deep hierarchies requiring multiple navigation steps
Solution Approach 1:
The patent introduces a camera as an intermediary tool to capture the wait screen display. The captured image serves as a mediator between the user and the icon information, allowing users to view icon details without navigating through deep menu hierarchies. The camera function bridges the gap between the displayed information and the user's need to access it easily.
Solution Approach 2:
The patent creates a copy of the wait screen display by capturing it with the camera. This copied image is then displayed in a confirmation screen, allowing users to view icon information without interacting with the original hierarchical menu structure. The copy enables direct access to information that would otherwise require multiple navigation steps.
2Ease of operation
If a camera is used to capture and display wait screen information, then icon information can be accessed without menu navigation, but power consumption increases due to camera operation
Solution Approach 1:
The patent implements periodic action by allowing the camera to capture the wait screen only when specifically triggered by user input, rather than continuously operating. The camera is activated on-demand when the user selects to view icon information, and the captured image is displayed temporarily. This periodic activation significantly reduces power consumption compared to continuous camera operation.
Solution Approach 2:
The patent applies partial action by using the camera function only for the specific purpose of capturing wait screen information, rather than utilizing the camera for all possible functions. The camera is activated minimally and only when needed to capture the display, and the captured image is shown briefly in a confirmation screen before being discarded, avoiding excessive power consumption.
3Loss of information
If the camera captures the entire wait screen including other application icons, then all icon information becomes visible, but it becomes difficult to identify the specific icon information the user wants to access
Solution Approach 1:
The patent extracts the specific icon information from the entire wait screen by allowing users to select and highlight the target icon in the captured image. The extraction process involves the user identifying and selecting the specific icon of interest from the full-screen capture, and then displaying only the relevant icon information in the confirmation screen, separating it from other unrelated icons.
Solution Approach 2:
The patent implements feedback by displaying the captured wait screen image in a confirmation screen where users can see what was captured and identify the target icon. The system provides visual feedback showing the entire captured image, allowing users to locate their desired icon, and then provides further feedback by displaying the specific icon information separately, confirming that the correct information has been retrieved.
