Solution Overview

Problem

Modern digital messaging applications do not provide an indication of a user's emotional and/or environmental state, limiting the ability to convey these states effectively.

Innovation Solution

Implementing a system that determines and conveys emotional and environmental states through biometric data, device interaction characteristics, and location data, using indicators such as emojis, punctuation marks, or color changes in the messaging interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If digital messaging applications use traditional typing indicators (e.g., three dots), then the system remains simple and easy to operate, but the ability to convey emotional and environmental states is lost

Engineering Contradiction:
Improveemotional state indicationVSAvoidmessaging system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple data sources (biometric sensors, device interaction data, location data) into a unified emotional state indicator system. This merging allows the system to convey comprehensive emotional information without requiring separate complex systems for each data type, thus reducing information loss while managing complexity through integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces intermediary components such as processors and software modules that mediate between raw sensor data and the final emotional indicators displayed to users. These intermediaries transform complex multi-source data into simple, interpretable visual cues (emojis, icons), preserving emotional information while maintaining system operability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the system manually tracks emotional states through user input, then the messaging system remains simple, but the speed and seamlessness of emotional state conveyance is reduced

Engineering Contradiction:
Improveemotional state conveyance speedVSAvoiduser interaction complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system automatically captures emotional state data through biometric sensors and device interaction tracking without requiring manual user input. This self-service approach enables rapid, seamless emotional state conveyance while maintaining ease of operation, as the system performs the tracking autonomously in the background without burdening the user.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements continuous feedback loops where the system monitors user emotional states in real-time and automatically updates messaging indicators. This feedback mechanism accelerates emotional state conveyance by providing real-time updates without requiring active user participation, thus improving productivity while preserving ease of operation.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the system collects comprehensive biometric and environmental data, then emotional state accuracy is improved, but the device complexity and data processing requirements increase

Engineering Contradiction:
Improveemotional state detection accuracyVSAvoiddata collection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the emotional state detection system into distinct functional modules: biometric data collection, device interaction tracking, location data acquisition, and indicator generation. This segmentation allows each component to be optimized independently for accuracy while managing overall system complexity through modular architecture, enabling precise emotional state measurement without overwhelming complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure provides computing systems and techniques for indicating an emotional and/or environmental state of a user in a digital messaging application. A computing device can determine an emotional and/or environmental state of a first user responsive to reading or responding to a message and can convey the determined emotional and/or environmental state to a second computing device, to be transiently presented by the second computing device.
