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, and a memory unit to store and execute control commands based on user interactions such as drags and drops, allowing users to easily execute functions by guiding control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is provided instead of a keypad, then the ease of operation is improved, but the difficulty of detecting and measuring increases due to unfamiliarity with touch processes
Solution Approach 1:
The system displays a control interaction guide before the user performs touch operations. This guide shows icons representing different drag operations (single drag, double drag, long drag) and their corresponding functions, allowing users to understand the touch processes in advance without needing to guess or trial-error through multiple touches.
Solution Approach 2:
The control interaction guide acts as an intermediary between the user and the touch screen operations. It translates complex touch gestures into visual icons that users can easily understand, bridging the gap between the physical touch action and the intended function execution.
2Ease of operation
If users are unfamiliar with touch screen processes, then the ease of operation deteriorates, but the loss of time increases due to unnecessary multiple touches
Solution Approach 1:
The control interaction guide is displayed in advance to show users the correct drag operations needed to execute functions. This prevents users from performing unnecessary multiple touches by providing the correct information before they start operating, thereby reducing time loss.
Solution Approach 2:
The system provides visual feedback through the control interaction guide that shows users what operations will achieve their desired functions. This feedback mechanism allows users to understand the relationship between their touch actions and the resulting functions, preventing repeated incorrect attempts.

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, detecting a touch on the display, providing a plurality of control guides at a location corresponding to the touch over the displayed photograph image, in response to detecting the touch, detecting a first drag in a first direction corresponding to a first one of the plurality of control guides provided on the display, removing the plurality of control guides from the display in response to detecting the first drag, detecting a second drag in a second direction different from the first direction of the first drag and corresponding to a second one of the plurality of control guides, the second drag is performed while maintaining touch on the display after the first drag is performed, adjusting a display characteristic of the photograph image corresponding to the second one of the plurality of control guides corresponding to the second drag, and displaying the photograph image having the adjusted display characteristic on the display in response to detecting the second drag.
