ATM Mode Switching via QR Code for Accessible User Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATMs often require users to have familiarity with the user interface, which can be a barrier for individuals with intellectual impairments or those who do not speak the language supported by the ATM, necessitating a more simplified user interface.
Innovation Solution
An ATM system that allows users to switch between a default mode with word-based representations and a basic mode with graphical images, enabling currency display as graphical images, and facilitating interaction via a mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ATM uses a default operating mode with word-based representations, then the interface is suitable for users with good UI skills and language proficiency, but it becomes inaccessible to users with intellectual impairments or language barriers
Solution Approach 1:
The ATM interface dynamically switches between default mode (word-based) and basic mode (graphical image-based) representations based on user selection. This dynamic adaptability allows the same interface to serve different user groups effectively, resolving the contradiction between optimizing for skilled users and accommodating users with impairments or language barriers.
Solution Approach 2:
The system changes the representation parameter of the interface from text-based to image-based. By altering this fundamental parameter, the ATM can accommodate different user needs - text-based for language-proficient users and image-based for those with intellectual impairments or language barriers, thereby improving both adaptability and accessibility.
2Ease of operation
If the ATM provides multiple operating modes, then user accessibility is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the complexity of mode selection and switching logic into a separate, well-defined system layer. The core display and transaction processing remain simple, while the mode management is handled as a distinct functional component. This separation prevents the complexity from permeating the entire system, maintaining ease of operation while supporting multiple accessibility modes.
Solution Approach 2:
The ATM interface is designed with multi-functionality to serve both default mode (for language-proficient users) and basic mode (for users with impairments or language barriers). By integrating multiple functions into a single unified interface system, the patent avoids the need for separate physical devices or complex configurations, thereby improving accessibility without proportionally increasing device complexity.

AI summary
A computing device, a computer program product, and a computer-implemented method for enabling a user to select between a default ATM operating mode in which actions are visually represented on a user interface with words, and a basic ATM operating mode in which actions are represented on the user interface with graphical images.
