Touch Interface Sliding Gesture for Intuitive Value Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic trading system for transferring value between a server-side and a portable terminal is not user-friendly, as it requires users to manually input transfer amounts and instructions using a numeric keypad, differing from the sense of cash exchange operations.
Innovation Solution
An information processing device and method that displays unit amounts on a screen, allowing users to transfer value by sliding their finger between designated regions representing server-side and terminal-side balances, with the system determining the transfer amount and direction based on the slide shift, mimicking the intuitive nature of cash transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a numeric keypad interface is used for value transfer, then the system can precisely control transfer amounts, but the operation becomes complex and non-intuitive for users
Solution Approach 1:
The patent replaces the mechanical numeric keypad input system with a touch-based sliding gesture system. Users slide their finger across the screen to indicate transfer amount and direction, transforming the input mechanism from discrete key presses to continuous tactile motion, thereby improving intuitiveness while maintaining precision through coordinate detection
Solution Approach 2:
The patent introduces visual indicators (such as displayed arrows or highlighted regions) as an intermediary between the user's sliding gesture and the system's interpretation. This intermediary provides real-time feedback about the detected slide direction and amount, making the abstract coordinate data meaningful to users and enhancing operational intuitiveness
2Measurement precision
If manual numeric input is required for value transfer, then the system can accurately determine transfer parameters, but the operational complexity increases significantly
Solution Approach 1:
The patent extracts the complex numeric input interface and replaces it with a simplified touch sliding gesture. By removing the need for users to manually input numbers, directions, and transfer parameters through multiple steps, the system reduces interface complexity while extracting only the essential function of parameter specification through intuitive physical motion
Solution Approach 2:
The patent merges multiple separate input tasks (specifying amount, specifying direction, confirming transfer) into a single unified sliding gesture. The slide's starting position, ending position, and distance simultaneously encode all necessary transfer parameters, thereby reducing the number of interface elements and steps required
3Adaptability or versatility
If a traditional electronic trading system interface is used, then the system can handle complex transfer scenarios, but the user experience diverges from natural cash exchange behavior
Solution Approach 1:
The patent introduces dynamic visual feedback that adapts to the user's sliding motion in real-time. The interface displays changing indicators (such as moving arrows or highlighted areas) that respond to the slide's progress, providing contextual information about the current transfer state and enhancing the natural feel of the interaction while maintaining versatility for different transfer scenarios

AI summary
An object is to provide a mechanism for giving an instruction to transfer value by an operation which is close to exchange of cash in terms of sense. A portable terminal incorporates a general-purpose IC chip storing a terminal-side value balance and can connect to an electronic money server via the Internet. In the electronic money server, a server-side value balance corresponding to the portable terminal is stored. The electronic money server and the portable terminal operate in cooperation with each other, and value can be transferred between the terminal-side value balance and the server-side value balance. The portable terminal displays a value transfer screen by a user interface and can accept the amount of value to be transferred and the direction of transfer from the value transfer screen by a user's touch operation.
