L-Shaped Image Display With Continuous Patterns for Shared-Space Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for creating an illusion of shared space with an interlocutor are limited by the need for robotic hands and video switching, leading to low flexibility and unclear user perception.
Innovation Solution
A terminal apparatus and method that displays a user's image on a vertical and horizontal display plane, with continuous patterns and shadows, creating a seamless illusion of shared space by using a server to process and transmit images between separate spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robotic hand is installed under the display to create an illusion of shared space, then the user perception of being in the same space is improved, but the device complexity and restriction increase
Solution Approach 1:
The patent removes the robotic hand component from the system entirely. Instead of using a physical robotic hand to create the illusion of shared space, the invention uses a camera to capture the user's hand and displays it on a screen, extracting the complex robotic mechanism while maintaining the core function of creating spatial illusion.
Solution Approach 2:
The patent uses a visual copy of the user's hand displayed on a screen to represent the physical hand in the shared space illusion. This copy approach replaces the need for a robotic hand, achieving the same visual effect with simpler technology.
2Reliability
If video switching is used to show different perspectives, then the illusion of shared space is improved, but the ease of operation and flexibility decrease
Solution Approach 1:
The patent implements dynamic switching between different camera perspectives (front view, side view, top view) based on real-time detection of user hand movements. This dynamic approach provides operational flexibility by automatically adapting the displayed perspective to the user's actions, eliminating the need for manual video switching operations.
Solution Approach 2:
The system uses feedback from hand detection to automatically control the video switching between different perspectives. The user's hand movements provide feedback that triggers appropriate camera angle changes, creating an intuitive and flexible interaction without requiring manual operation.
3Reliability
If multiple display planes are used to show continuous patterns, then the user perception of continuous space is improved, but the device complexity increases
Solution Approach 1:
The patent extends the display into a third dimension by adding a horizontal display plane adjacent to the vertical display plane. This creates an L-shaped display configuration that allows continuous patterns to flow across both planes, enhancing the perception of continuous space while adding only one additional display dimension rather than requiring complex multi-screen arrangements.

AI summary
A terminal apparatus is a terminal apparatus configured to display a user image being an image of a first user to a second user in a second space separate from a first space in which the first user is present, the terminal apparatus including a controller configured to display, on a vertical display plane extending in a vertical direction, a first image being an image of a desk or a floor, together with the user image, display, on a horizontal display plane extending in a horizontal direction, a second image being a continuous image with the first image, the horizontal display plane being adjacent to a lower end of the vertical display plane, and when displaying the first image and the second image, draw a pattern on the first image and a pattern on the second image as continuous patterns with each other.
