Augmented Reality Interface for Digital Signage Interaction

Solution Overview

Problem

Existing digital signages are predominantly one-way, limiting user interaction and requiring multiple installations to accommodate multiple users simultaneously, which increases costs. Additionally, two-way digital signages with touch screens pose public health concerns, especially during epidemics.

Innovation Solution

A method and system that enable a one-way digital signage to function interactively like a two-way signage by acquiring a picture of the signage content, estimating identification information using comparison target content, and displaying an augmented reality interface corresponding to the content, allowing for contactless interaction and multi-user access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If one-way digital signage is used to reduce cost, then installation cost is reduced, but user interaction capability deteriorates

Engineering Contradiction:

Improveinstallation costVSAvoiduser interaction capability

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces a camera as an intermediary device that captures images of the digital signage content. This intermediary enables interaction by allowing the system to recognize and process user gestures (such as pointing at specific content), thereby adding interaction capability to the one-way signage without requiring touch screen hardware.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical touch screen interface with an optical recognition system. Instead of requiring physical contact through a touch screen, the system uses camera-based image capture and processing to detect user intentions, substituting mechanical interaction with optical field-based interaction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If touch screen is used to enable user interaction, then user interaction capability is improved, but public health safety deteriorates

Engineering Contradiction:

Improveuser interaction capabilityVSAvoidpublic health safety

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical touch screen interface with an optical recognition system. Instead of requiring physical contact through a touch screen, the system uses camera-based image capture and processing to detect user intentions, substituting mechanical interaction with optical field-based interaction that requires no physical contact.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a camera as an intermediary device that captures images of the digital signage content. This intermediary enables interaction by allowing the system to recognize and process user gestures (such as pointing at specific content), thereby adding interaction capability to the one-way signage without requiring touch screen hardware.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If multiple two-way digital signages are installed to accommodate multiple users, then user interaction capability is improved, but installation cost deteriorates

Engineering Contradiction:

Improvemulti-user interaction capabilityVSAvoidinstallation cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent makes a single digital signage serve multiple users simultaneously by equipping it with camera-based gesture recognition capability. The signage can detect and respond to multiple users' gestures independently, allowing one signage to function as multiple interactive stations would, thereby reducing the total number of installations needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of multiple separate interactive signages into a single unified system. By integrating camera-based gesture recognition, one signage can handle multiple users' interactions concurrently, merging what would traditionally require multiple separate installations into a single multi-functional unit.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for managing an augmented reality interface related to a content provided by a digital signage is provided. The method includes the steps of: acquiring a picture photographed by a device in relation to a content provided by a digital signage; and estimating identification information on the content with reference to a comparison target content related to the content and included in a content pool, and causing an augmented reality interface corresponding to the content to be displayed together with the photographed picture, on the basis of the identification information on the content.
