TTY Caller ID Visual Differentiation for Cognitive Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional teletypewriter (TTY) devices are inflexible for modern communication systems due to their serial processing and limited display capabilities, making it difficult for users with cognitive impairments to manage incoming calls and conversations effectively.
Innovation Solution
A mobile device application that identifies the corresponding party in a TTY call by using caller identification data to modify the display settings, including font, line breaks, and inserting names, allowing users to recognize callers through visual cues like pictures, names, and phone numbers, enhancing the user experience by simplifying call management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional TTY devices use serial processing and single-line display, then the device complexity is reduced and ease of manufacture is improved, but the ease of operation deteriorates and productivity decreases
Solution Approach 1:
The patent segments the single-line display into multiple visual lines, allowing simultaneous display of incoming caller information and outgoing message content. This segmentation enables users to see both caller identification and message text without confusion, improving ease of operation while maintaining device simplicity
Solution Approach 2:
The patent adds visual dimensionality to the traditional TTY interface by displaying information in multiple lines with different visual characteristics (such as different fonts or styles for incoming vs. outgoing messages). This dimensional change allows users to distinguish between incoming and outgoing communications more easily, enhancing usability without increasing device complexity
2Device complexity
If traditional TTY devices use single-line display without visual differentiation, then the device complexity is minimized, but the loss of information increases and measurement precision deteriorates
Solution Approach 1:
The patent applies local quality by using distinct visual characteristics (such as different fonts, styles, or formatting) for different types of information displayed on the TTY. Incoming caller information is visually differentiated from outgoing messages, allowing users to quickly identify the source and direction of communications without adding complex hardware
3Device complexity
If traditional TTY devices process messages serially without visual cues, then the device complexity remains low, but the loss of time increases and productivity decreases
Solution Approach 1:
The patent implements preliminary action by displaying incoming caller identification information before the user needs to respond or take action. This allows users to prepare mentally and physically for the incoming communication, reducing response time and improving productivity while maintaining simple serial processing
Data Source
AI summary
A method and system are provided that examine incoming and outgoing TTY transmissions to determine an identifier for distinguishing between correspondents in a TTY call. The system may utilize existing contact information associated with an incoming call to provide context to a user for accepting incoming calls and during conversations and may apply various display settings. For TTY users, the additional context simplifies the ability to conduct critical reasoning, especially those with cognitive impairments. In particular, a picture from the user's address book is provided to assist in identifying the caller. The other display settings may include modified font styles, colors, multi-line display etc. to differentiate between incoming and outgoing messages.
