Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing augmented reality (AR) technologies do not effectively manage private messaging between users, particularly in scenarios where not everyone has a communication device, leading to lack of privacy and missed opportunities for communication, especially in situations where physical notes or direct verbal communication are relied upon.

Innovation Solution

An electronic device with AR display capabilities that authenticates users and allows authorized individuals to create and receive private messages, which can be visually presented on AR display devices, ensuring that messages are only seen by intended recipients through identification and access credential management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If physical notes are used for messaging, then accessibility for users without communication devices is improved, but privacy and security of messages deteriorate

Engineering Contradiction:

Improveaccessibility for users without communication devicesVSAvoidprivacy and security of messages

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an AR display device as an intermediary medium that allows users without smartphones to leave messages that are displayed in augmented reality space. The messages are encrypted and can only be viewed by the intended recipient through their AR device, combining the accessibility of physical notes with the security of digital encryption.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical system of physical notes with an optical/digital system using AR display technology. Messages are projected into the user's field of view through AR lenses, eliminating the need for physical paper while maintaining accessibility for non-smartphone users.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Speed

If direct verbal communication is used, then immediacy of communication is improved, but privacy and convenience when parties are not in the same temporal space deteriorate

Engineering Contradiction:

Improveimmediacy of communicationVSAvoidconvenience when parties are not in the same temporal space

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The patent enables users to pre-record messages that can be played back at a later time. The AR display device stores and retrieves messages asynchronously, allowing communication without requiring both parties to be present simultaneously, thus combining immediacy with flexibility.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If AR display technology is implemented for private messaging, then message privacy and security are improved, but device complexity and cost deteriorate

Engineering Contradiction:

Improvemessage privacy and securityVSAvoiddevice complexity and cost

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent leverages the existing AR display hardware (lenses, processors, displays) already developed for other purposes and repurposes it for private messaging. This avoids the need to create entirely new specialized devices, reducing overall system complexity while maintaining security features.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An electronic device, computer program product, and method provide private messaging between people at a frequented location by using one or more AR display devices. The electronic device communicatively connects to a particular AR display device and attempts to identify access credentials to the electronic device of a particular person wearing the particular AR display device. The electronic device identifies that the particular person is a second person has limited access credentials, at the electronic device, to an AR user interface for leaving a private AR message intended for a first person who has full access credentials to the electronic device. The electronic device presents, at the particular AR display device, the AR user interface. The electronic device receives an AR private message from the particular AR display device and stores the AR private message for retrieval at the electronic device by first person.
