3D Interface Boundary Projection for Multi-Mode Virtual Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interface devices struggle to visually distinguish boundary positions within a virtual space, making it difficult for users to recognize the transition between different operation modes.
Innovation Solution
An interface device and system that includes a detection unit to detect the three-dimensional position of a target in a virtual space, a projection unit to project an aerial image indicating the boundaries of operation spaces, and a display unit to visually represent these boundaries, allowing users to perform multiple operations associated with each space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual planar space is set with multiple operation spaces for different modes, then the functionality and operation versatility are improved, but the visual recognizability of boundary positions deteriorates
Solution Approach 1:
The patent applies color changes by displaying boundary positions using different luminance levels or colors. The projection unit projects aerial images that highlight boundary positions with distinct visual characteristics, allowing users to clearly distinguish between different operation spaces. This resolves the contradiction by maintaining multiple operation modes while making boundaries visually recognizable through color/luminance differentiation.
Solution Approach 2:
The patent introduces an intermediary visual element (the projected aerial image showing boundary positions) that mediates between the virtual operation spaces and the user. This intermediary provides visual feedback about space boundaries without interfering with the core operation functionality, thus maintaining versatility while improving boundary recognizability.
2Device complexity
If boundary positions are not visually indicated, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system provides self-service by automatically projecting aerial images that indicate boundary positions. The projection unit autonomously displays visual guides for operation spaces without requiring additional manual configuration or complex hardware modifications. This maintains relative simplicity while significantly improving ease of operation through automatic visual feedback.
Solution Approach 2:
The patent replaces potential mechanical or physical boundary indicators with optical/projection-based visualization. Instead of using physical markers or complex mechanical systems to indicate boundaries, the system uses projected aerial images to show boundary positions, reducing mechanical complexity while enhancing operational clarity.

AI summary
An interface device includes: a detection unit that detects the three-dimensional position of a detection target in a virtual space; and a projection unit that projects an aerial image onto the virtual space. The virtual space is divided into a plurality of operation spaces for each operation executable by a user in a case where the three-dimensional position of the detection target detected by the detection unit is included, the operation being defined in each of the operation spaces, and a boundary position of each operation space in the virtual space is indicated by an aerial image projected by the projection unit.
