Pepper's Ghost Stage Display for Natural Remote Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conferencing technologies fail to create a natural and realistic interaction between local and remote talents on a stage, as the remote talent's presence appears illusory, making genuine eye contact and real-time interaction challenging.
Innovation Solution
A system comprising cameras, monitors, and a conference manager that utilize Pepper's Ghost illusion and holographic projections to create the illusion of the remote talent's presence on stage, allowing for synchronized video and audio feeds, enabling eye contact and natural interaction with both the local talent and the audience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Pepper's Ghost illusion and holographic projections are used to create the illusion of remote talent's presence on stage, then the realism and naturalness of interaction is improved, but the device complexity increases
Solution Approach 1:
A camera positioned at the remote talent's location serves as an intermediary to capture video feeds that are then projected onto a transparent display surface. This intermediary device enables the illusion of presence by mediating between the remote talent and the local stage environment, allowing realistic interaction without requiring the remote talent to physically be on stage.
Solution Approach 2:
The system creates optical copies of the remote talent through video projection onto transparent surfaces. These copies appear to be physically present on stage while actually being visual representations generated from video feeds, enabling realistic interaction while simplifying the overall system architecture compared to more complex holographic technologies.
2Ease of operation
If multiple cameras and display apparatuses are used to enable eye contact and natural interaction, then the quality of interaction is improved, but the device complexity increases
Solution Approach 1:
Multiple video feeds from different camera angles are merged and projected onto a single transparent display surface. This combining of multiple visual streams into one integrated display enables natural eye contact and interaction while reducing the number of separate display devices needed, thereby managing system complexity.
Solution Approach 2:
The system transitions from traditional two-dimensional screen displays to three-dimensional transparent surface projections. This dimensional change allows participants to see each other's eyes and facial expressions more naturally, improving interaction quality while the transparent nature of the display reduces visual clutter and perceived complexity.
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 real-time, natural, and realistic on-stage conferencing by creating the illusion of the remote talent's presence, facilitating genuine interaction and maintaining audience engagement.
Implementation Method 1
Pepper's Ghost is an illusion used to create an image of an object that appears to be part of a real-life scene or environment. This technique has been used in haunted houses to make ghosts appear and move about a room.

AI summary
A system comprises a stage area and an audience area with a line of sight view of the stage area. The system also includes a first display that reproduces a first video feed of a first perspective of a remote talent. The first video feed may appear, from the perspective of the audience area, to be within a first region of the stage area. The system further includes a first camera directed at the audience area and aligned so that its field of view corresponds to a line of sight from the first region to the audience area. The system additionally includes a second display viewable from a second region of the stage area and hidden from view of the audience area. The second display reproduces a second video feed of a second perspective, different that the first perspective, of the remote talent. The system also includes a second camera directed at the second region of the stage area and aligned so that its field of view corresponds to a line of sight from the second display to the second region.
