Solution Overview

Problem

Online live shows lack the personal interaction and sense of connection between performers and viewers, as the relationship between viewers and performers is tenuous, leading to lower viewer satisfaction.

Innovation Solution

An image transmission system that includes a first image capture apparatus to capture images of a performer from a virtual seat, a second image capture apparatus to capture wider shots, a transmission controller to transmit specific images based on the performer's line of sight, and a detector to identify the direction of the performer's line of sight, ensuring that viewers associated with virtual seats receive images that simulate eye contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single camera captures all viewers simultaneously, then all viewers can see the performance, but the personal interaction and eye contact experience is lost

Engineering Contradiction:
Improvepersonal interaction experienceVSAvoidmultiple image capture apparatus
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the audience into multiple virtual seats, with each seat having its own dedicated image capture apparatus. This allows the performer's line of sight to be directed at specific virtual seats, creating personalized eye contact experiences for different viewers simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transmission controller acts as an intermediary that receives images from multiple capture apparatuses, detects the performer's line of sight direction, and selectively transmits appropriate images to corresponding terminal apparatuses. This mediator enables the complex multi-camera system to function seamlessly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple cameras are used to capture different views, then personal interaction can be simulated, but the system complexity increases

Engineering Contradiction:
Improveviewing experience qualityVSAvoidimage transmission system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each image capture apparatus serves multiple functions: capturing the performer from a specific virtual seat perspective, detecting the performer's line of sight direction, and providing images for transmission to corresponding viewers. This multi-functionality reduces the need for separate dedicated devices.

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

Solution Approach 2:

The system uses the performer's own line of sight direction as the control signal for image selection and transmission. The performer naturally looks at different virtual seats during the performance, and the system automatically detects and responds to these directions without requiring external control inputs.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the performer looks at the camera, then all viewers see the performer's gaze, but individual viewers do not feel personal attention

Engineering Contradiction:
Improvepersonalized attentionVSAvoidline of sight direction information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system replaces the mechanical concept of a single fixed camera with a multi-camera array positioned at different virtual seat locations. This allows the system to capture the performer's line of sight from multiple perspectives and selectively transmit the appropriate view to each viewer based on where the performer is looking.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A first image capture apparatus captures a first image of a performer in a theater from a position of a virtual first seat that has been set in the theater. A second image capture apparatus captures a second image including the performer from a position different from the position of the first image capture apparatus. A detector detects a direction of line of sight of the performer. A transmission controller transmits the second image to a terminal apparatus of a viewer associated with the virtual first seat, and transmit the first image to the terminal apparatus based on the direction of the line of sight of the performer having turned toward the virtual first seat.
