Touch Screen Control Interaction Guide for Mobile Terminals
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 mobile terminal configuration that includes a touch screen with a display unit for showing a function execution screen, a control unit to display a control interaction guide upon request, and a memory unit to store and execute control commands based on drag characteristics detected on the touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch screen is used instead of a keypad, then the device size is reduced and modernization is achieved, but user operation becomes more difficult due to unfamiliarity with touch processes
Solution Approach 1:
The system displays a control interaction guide before the user performs the actual operation. This preliminary action provides users with advance information about the control process, including drag operations, tap operations, and other touch gestures, thereby reducing operation difficulty when using the touch screen for the first time or when encountering new functions
Solution Approach 2:
A control interaction guide is introduced as an intermediary element between the user and the touch screen interface. This guide acts as a mediator that translates complex touch operations into understandable instructions, helping users comprehend the relationship between their actions and system responses without requiring prior knowledge of touch screen operations
2Productivity
If users are unfamiliar with touch screen processes, then multiple touches are required to complete functions, but this increases operation time and reduces efficiency
Solution Approach 1:
The control interaction guide provides real-time feedback to users about what operations to perform and what results to expect. By displaying drag operations, tap operations, and other control instructions, the system guides users through the correct sequence of actions, preventing unnecessary retries and reducing the time required to complete functions
Solution Approach 2:
The system performs preliminary guidance by displaying the control interaction guide before users attempt operations. This advance instruction prevents users from making incorrect touches or requiring multiple attempts, thereby reducing operation time and improving overall productivity

AI summary
A method for providing a graphical user interface on a display of a device includes: displaying a photograph 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 the touch input; receiving a drag input corresponding to one of the plurality of control guides displayed on the display; adjusting a display characteristic of the photograph image corresponding to the one of the plurality of control guides, in response to the drag input; and displaying the photograph image having the adjusted display characteristic on the display, wherein the display characteristic is a magnification of the photograph image.
