Solution Overview

Problem

Current display systems cannot simultaneously provide different visual and audio content to multiple users without requiring each viewer to see or hear the content intended for others, limiting the ability to offer personalized experiences on a single screen.

Innovation Solution

A screen sharing system using synchronized shuttered filters and light-controlled LCD glasses that allow each user to view and hear only their intended video feed, enabling multiple users to see different perspectives of the same content on a single display without interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single display is used to provide content to multiple users, then device complexity is reduced, but each user cannot view different content without seeing others' content

Engineering Contradiction:
Improvedisplay system complexityVSAvoidcontent personalization capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The display system is segmented into multiple independent content channels, with each user receiving a dedicated video feed that is selectively presented to them through synchronized shutter glasses. The display alternates between showing different content to different users, and the shutter glasses segment the visual information so each user only perceives their intended content.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses periodic action by rapidly alternating the display between different video feeds in synchronization with the shuttering of the glasses. The display switches between showing content for User A and User B at rates that create the perception of simultaneous independent viewing, enabling content personalization without requiring multiple physical displays.

Inventive Principle:
Principle #19Periodic action

2Adaptability or versatility

If multiple video feeds are displayed simultaneously on a single screen, then content versatility is improved, but users experience visual interference from content not intended for them

Engineering Contradiction:
Improvemulti-feed display capabilityVSAvoidvisual interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The display rapidly alternates between showing different video feeds in a periodic manner synchronized with the shuttering of the glasses. This periodic switching occurs at rates high enough to create the illusion of simultaneous independent content delivery to multiple users, while actually presenting only one feed at a time to each user's eyes through the shutter mechanism.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The shutter glasses act as an intermediary device between the display and each user's eyes. They selectively block or permit light from the display based on the currently shown video feed, thereby eliminating visual interference from feeds not intended for that user while allowing the display to show multiple feeds in rapid succession.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If synchronized shutter glasses are used to separate video feeds, then content isolation is improved, but device complexity increases

Engineering Contradiction:
Improvecontent isolationVSAvoidshutter synchronization system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The shutter glasses serve multiple functions: they act as both the content delivery mechanism and the isolation barrier. The same optical component that delivers the video feed to the user's eyes also blocks unwanted feeds through synchronized shuttering. This multi-functionality reduces the need for additional separate isolation devices, thereby limiting the increase in overall system complexity.

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

4Adaptability or versatility

If head-mounted displays are used to provide personalized content, then content personalization is improved, but cost and complexity increase significantly

Engineering Contradiction:
Improvepersonalized viewing experienceVSAvoidhead-mounted display system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of providing each user with a separate physical display device (head-mounted display), the system creates a functional copy of the personalized viewing experience by using a single shared display combined with shutter glasses. The shutter glasses replicate the effect of having separate displays by selectively blocking light paths, thereby achieving content personalization at a fraction of the cost and complexity of true head-mounted displays for each user.

Inventive Principle:
Principle #26Copying

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables multiple users to view and hear distinct video feeds or game perspectives from a single display, reducing distraction and allowing for personalized experiences without the need for complex or expensive head-mounted displays.

Implementation Method 1

A first shuttered filter is synchronized to the display such that the first filter is shuttered when the second video feed image is displayed, and a second shuttered filter is synchronized to the display such that the second filter is shuttered when the first video feed image is displayed.

Methodology Applied
Scientific EffectLight blocking: Absorption (EM radiation)

Implementation Method 2

The display is controlled to alternately display an image from a first video feed and an image from a second video feed.

Methodology Applied
Scientific EffectElectroluminescence: Electroluminescence

AI summary

An apparatus for interfacing with a display screen is provided. The apparatus includes a frame. The frame includes (a) a pair of shutter lenses, (b) a light coupled to the frame; and (b) a circuit integrated with the frame to control the pair of shutter lenses and control the light coupled to the frame. The circuit is configured to communicate with a display device to enable synchronization of the shutter lenses and the display device. The light is analyzed to determine position of the frame relative to the display device, and the position is used to cause an adjustment in display output when viewed from the perspective of the position of the frame.
