Context-Based Messaging for Augmentative Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmentative and alternative communication (AAC) messaging systems struggle to provide context-aware messaging for users with pragmatic language impairments, such as Autism and Asperger's Syndrome, as they often misinterpret phrases due to lack of contextual understanding, and can confuse other AAC users with overlapping or misinterpreted meanings.
Innovation Solution
A socially provided context-based messaging system that receives message content, matches objects within the message to relevant context information from a user's social network, and displays this context information to the recipient, utilizing a combination of pictures, chat, voice, and web cam images to enhance understanding, with moderation by third parties like caregivers or therapists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If AAC picture boards are used for messaging, then communication capability is provided for users with impairments, but context understanding is lost leading to misinterpretation
Solution Approach 1:
The patent introduces context information as an intermediary element that mediates between the AAC user's message and the recipient's interpretation. This context information, sourced from social networks and filtered by moderators, provides additional meaning and background that bridges the gap caused by the simplified AAC interface, preventing misinterpretation while maintaining ease of use.
2Ease of operation
If simple AAC picture boards are used, then ease of use is improved, but communication accuracy deteriorates due to overlapping meanings
Solution Approach 1:
Context information acts as a mediator that disambiguates overlapping meanings in AAC communications. By providing additional contextual details from social networks and filtering them through moderators, the system maintains the simplicity of the AAC interface while significantly improving communication accuracy and reducing misunderstandings.
3Reliability
If context information is added to AAC messages, then communication accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses context information as an intermediary layer that manages the complexity of providing accurate communication. Rather than complicating the AAC interface itself, the context information is sourced externally from social networks and filtered by moderators, allowing the core AAC system to remain simple while achieving high communication accuracy.
Solution Approach 2:
The system leverages existing social network data to automatically provide context information, reducing the need for manual configuration or complex processing within the AAC system itself. The context is self-provided through users' existing social connections and activities.
4Loss of information
If social network context information is integrated, then message relevance is enhanced, but information processing requirements increase
Solution Approach 1:
The patent extracts only the relevant context information from social networks that is necessary for understanding AAC messages, rather than processing all available social network data. This selective extraction approach enhances message relevance while minimizing the quantity of information that needs to be processed.
Solution Approach 2:
Moderators serve as intermediaries who filter and select context information from social networks, reducing the volume of data that needs to be processed while ensuring that only relevant and appropriate context is added to AAC messages.

AI summary
Socially provided context-based messaging can include receiving a message content in a messaging system from a user, wherein the content includes objects; matching one or more objects of the message content to socially provided context information, which the socially provided context information is information relevant to an object obtained from a social network to which the user belongs; and displaying the socially provided context information with the message content for a recipient user to receive.
