Terminal Accessibility Customization via Preference Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with disabilities face challenges in accessing and using self-service terminals and ATMs due to limited accessibility features, and they often need to manually configure these settings for each transaction, which is inconvenient.
Innovation Solution
A system that allows users to customize and register their accessibility preferences, generating a preference code that can be scanned or used to automatically configure the terminal's transaction interface, enabling seamless and consistent accessibility settings across different terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of accessibility settings is required for each transaction, then terminal accessibility features can be customized, but user convenience and time efficiency deteriorate
Solution Approach 1:
The system performs preliminary action by storing accessibility preferences in advance in a database associated with user identifiers (such as loyalty account numbers or device identifiers). When a user approaches the terminal, the system automatically retrieves and applies these pre-stored preferences without requiring manual reconfiguration, thus resolving the contradiction between customization capability and ease of operation.
Solution Approach 2:
The terminal system provides self-service functionality by automatically detecting user identifiers (through scanning, NFC, or account lookup), retrieving stored accessibility preferences, and applying them autonomously. This eliminates the need for users to manually configure settings each time, while still providing personalized accessibility customization through the initial preference setup.
2Ease of operation
If accessibility features are limited on existing terminals, then device complexity remains low, but usability for people with disabilities deteriorates
Solution Approach 1:
The system implements universality by creating a separate preference management layer that serves all users regardless of their specific accessibility needs. The terminal hardware remains relatively simple, but the system can accommodate multiple accessibility profiles and preferences through software configuration, allowing the same terminal to serve both able-bodied users and users with various disabilities without requiring complex specialized hardware for each case.
3Productivity
If accessibility preferences are not automatically applied, then system complexity remains low, but transaction efficiency and user satisfaction deteriorate
Solution Approach 1:
The system introduces an intermediary preference database layer between the user and the terminal transaction system. This intermediary stores accessibility preferences and automatically retrieves them based on user identifiers, acting as a mediator that enables efficient preference application without requiring complex direct integration between terminals and user devices. The intermediary handles the complexity of preference management centrally.
Data Source
AI summary
An individual with an impairment or disability registers terminal accessibility preferences. The individual is provided a code that when scanned at a terminal causes the terminal to configure the transaction interface of the terminal to apply or enforce the individual's registered accessibility preferences in connection with a transaction on the terminal. The individual's registered accessibility preferences can be linked to a loyalty account of the individual such that when the individual initiates a transaction on a terminal and provides their loyalty identifier, the corresponding accessibility preferences are obtained from the loyalty account and applied and/or enforced on the transaction interface during the transaction.
