Touchscreen Drag-and-Drop Rating Interface for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling mobile terminal devices with touch-sensitive displays are inefficient, user-unfriendly, and lack process security when assigning ratings or evaluations, particularly on small devices, leading to imprecise and unreliable data logging and evaluation.
Innovation Solution
The method involves displaying multiple graphic elements and delimited display areas simultaneously, allowing users to drag and drop them for precise and differentiated assignments, with improved traceability and data management, enabling secure and reliable data transmission to an application server for logging and evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple graphic elements are displayed and dragged simultaneously on a small display device, then assignment precision and reliability are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The display area is segmented into multiple delimited display areas, each representing a specific rating level. This segmentation allows multiple graphic elements to be evaluated simultaneously against different rating categories, improving assignment precision without overwhelming the user with a monolithic interface.
Solution Approach 2:
The patent introduces a spatial dimension to rating evaluation by arranging delimited display areas in a structured layout on the touchscreen. Multiple graphic elements can be dragged to different spatial locations simultaneously, adding a dimensional aspect to the evaluation process that enhances precision while maintaining clarity.
2Loss of information
If multiple graphic elements are displayed and dragged simultaneously, then information content and traceability are improved, but ease of operation deteriorates
Solution Approach 1:
The system provides visual feedback by displaying delimited display areas that represent different rating levels. As users drag graphic elements, the system maintains traceability of assignments through the structured layout and confirmation of dropped elements, enhancing information content while guiding users through the process.
Solution Approach 2:
The drag-and-drop interface allows users to independently evaluate multiple graphic elements by directly dragging them to appropriate delimited display areas. This self-service approach enables users to complete evaluations efficiently without requiring complex navigation or multiple interaction steps, maintaining ease of operation while increasing information content.
3Ease of operation
If drag and drop operation is used for assigning ratings, then user-friendliness is improved, but process security deteriorates
Solution Approach 1:
The patent pre-defines delimited display areas that represent specific rating levels before the user interaction begins. This preliminary structuring ensures that all possible rating assignments are predetermined and controlled, maintaining process security while allowing users to freely drag and drop elements into the appropriate pre-defined areas.
Solution Approach 2:
The delimited display areas act as intermediaries between the user's drag-and-drop action and the final rating assignment. By requiring users to drop elements into these controlled intermediary zones rather than allowing free placement, the system maintains process security and reliability while preserving the user-friendliness of the drag-and-drop interface.

AI summary
The method involves representing two graphic elements (3-11) e.g. images or icons, on a touch-sensitive display device (2), and detecting contact at the display device. The graphic elements are extracted and dropped on defined display areas (12-15) according to the detected contact at the display device. Data is transmitted to an application server (16). The server, on which the display regions drop the graphic elements, and a mobile terminal (1) e.g. mobile telephone, is synchronized with the data dependant on the protocols of the server. An independent claim is also included for a mobile telephone with a touch-sensitive display device.
