Voice Input ATM System for Privacy and Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated teller machines (ATMs) are not equipped to handle users with visual impairments, as they require screen navigation for transactions, which can be challenging for vision-impaired individuals.
Innovation Solution
The system allows voice input at ATMs by using an audio input/output device to provide audio commands and receive audio responses, enabling users to interact through voice commands instead of screen navigation, ensuring discreet communication and accurate mapping of user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ATMs use display screens for user interaction, then visual information is clearly presented, but users with visual impairments cannot independently perform transactions
Solution Approach 1:
The patent replaces the visual display screen interface with an audio-based interface. The ATM system generates audio messages that present transaction options to the user, and captures audio responses from the user. This substitution of visual mechanical interaction with acoustic interaction enables vision-impaired users to independently perform transactions by listening to audio prompts and providing voice commands.
2Adaptability or versatility
If the ATM provides audible transaction options, then vision-impaired users can access the system, but the selected transaction may be audibly revealed to others
Solution Approach 1:
The patent introduces an intermediary verification mechanism between the user's selection and the system's execution. After the user provides a voice command, the system generates an audio verification message that confirms the selected transaction option. The user must provide additional audio confirmation to proceed. This intermediary verification step ensures that the transaction is correctly identified while maintaining privacy, as the verification is performed through private audio channels rather than public display.
3Ease of operation
If the system uses voice commands for input, then user independence is enhanced, but accurate mapping of voice indications to transaction options is challenging
Solution Approach 1:
The patent implements a feedback mechanism where the system generates audio verification messages that present the selected transaction option back to the user for confirmation. This feedback loop allows the user to verify that their voice command was correctly interpreted and mapped to the intended transaction. If the mapping is incorrect, the user can provide corrective audio input. This feedback process ensures accurate mapping while maintaining user independence.
Data Source
AI summary
Embodiments disclosed herein generally relate to a system and method for transacting at an ATM. A computing system receives a request from the ATM to provide audio commands for an input having one or more components. The computing system generates an audio message for a component of the one or more components. The computing system receives an indication from the user to select an entry from the set of candidate entries as the component. The indication from the user does not include a recitation of the first entry. The computing system maps the indication to a respective candidate in the set of candidate entries. The computing system generates a verification audio message for the user to audibly verify a correct mapping between the indication and the respective candidate in the set of candidate entries. The computing system receives an audible verification from the user.
