Touch Screen Control Guides for Mobile Terminal Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals with touch screens face difficulties in controlling various functions due to the small size of keypads and unfamiliarity with touch screen processes, leading to unnecessary multiple touches.
Innovation Solution
A method and apparatus for a mobile terminal that displays a function execution screen and a control interaction guide, allowing users to execute control commands by detecting drags on the touch screen, calculating drag characteristic values, and executing corresponding functions, while providing guidance through displayed symbols and directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch screen is provided instead of a keypad, then the mobile terminal can support various supplementary functions, but users may have difficulty in controlling various functions if they are not familiar with processes of performing a function
Solution Approach 1:
The system displays control interaction guides before the user needs to perform operations. These guides show control commands and their effects in advance, allowing users to understand the touch screen processes before actually using them, thereby reducing difficulty in controlling functions.
Solution Approach 2:
Control interaction guides serve as an intermediary between the user and the touch screen interface. The guides translate complex touch operations into understandable visual instructions, mediating the interaction and making it easier for users to control various functions without being familiar with the interface.
2Ease of operation
If users are unfamiliar with touch screen processes, then they may perform unnecessary multiple touches, but providing detailed guidance may increase display complexity
Solution Approach 1:
The control interaction guides are displayed locally at relevant positions on the screen rather than occupying the entire display. The guides appear only when needed and only in the areas where control commands are relevant, providing necessary information without increasing overall display complexity.
Solution Approach 2:
The control interaction guides are dynamically displayed and hidden based on user interaction states. The guides appear when the user needs assistance and disappear when the user understands or completes the action, allowing the display to adapt its complexity level based on the situation.

AI summary
A method for providing a graphical user interface on a display of a device includes: displaying a photograph an image on the display of the device, receiving a touch input made on the display, superimposedly displaying a plurality of control guides at a location corresponding to the touch input over the displayed photograph image in response to receiving the touch input, receiving a drag input corresponding to one of the plurality of control guides displayed on the display, removing adjusting a display characteristic of at least one of the plurality of control guides in response to receiving the drag input, and displaying the adjusted plurality of control guides on the display.
