Solution Overview

Problem

Current multiuser communication systems lack logic to determine whether information requested by a user should be shared publicly or privately within the session.

Innovation Solution

Implement a system that detects user invocation and search inputs to determine if information should be shared publicly, privately, or semi-publicly based on criteria such as hand gestures, gaze direction, and voice modulation, using a public-private interaction engine to manage interactions during a multiuser communication session.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If information is shared publicly with all users in a multiuser communication session, then group interaction and collaboration are enhanced, but user privacy and confidential information protection are compromised

Engineering Contradiction:
Improveinformation sharing flexibilityVSAvoidprivacy control
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments information sharing into distinct categories: public interactions visible to all users, private interactions visible only to the requesting user, and semi-public interactions visible to selected users. This segmentation allows the system to simultaneously protect privacy while enabling group collaboration by directing different types of information to appropriate audiences.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts information sharing scope based on real-time detection of user inputs such as hand gestures, gaze direction, and voice modulation. The public-private interaction engine continuously monitors these inputs and adapts the distribution of information accordingly, transitioning between public, private, and semi-public sharing modes as needed.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a system monitors multiple user inputs (hand gestures, gaze direction, voice modulation) to determine information sharing scope, then privacy and interaction control are improved, but system complexity increases

Engineering Contradiction:
Improveinteraction control accuracyVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The public-private interaction engine serves multiple functions: detecting hand gestures, analyzing gaze direction, interpreting voice modulation, and determining information sharing scope. By consolidating these diverse detection and decision-making functions into a single multi-functional engine, the system achieves reliable interaction control without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The public-private interaction engine acts as an intermediary layer between various input detection mechanisms and the information distribution system. It receives signals from multiple sensors (gesture detectors, gaze trackers, voice analyzers), processes them centrally, and makes unified decisions about information sharing, thereby simplifying the architecture compared to having separate systems for each function.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method of invoking public and private interactions during a multiuser communication session includes presenting a multiuser communication session; detecting a user invocation input that corresponds to a trigger to a digital assistant; detecting a user search input that corresponds to a request for information; obtaining the information based on the request; presenting the information; in accordance with a determination that at least one of the user invocation input and the user search input satisfy first input criteria associated with a first request type: transmitting the information to other electronic devices for presentation to other users; and in accordance with a determination that at least one of the user invocation input and the user search input satisfy second input criteria associated with a second request type: forgoing transmitting the information to the other electronic devices for presentation to other users.
