Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users have difficulty visually recognizing the boundary positions between operation spaces in a virtual plane space, making it challenging to distinguish between different modes of operation in conventional non-contact operation input systems.
Innovation Solution
An interface system that includes a detecting unit to determine the three-dimensional position of a detection target within a virtual space divided into multiple operation spaces, projects an aerial image indicating boundary positions, and outputs operation information based on these positions to facilitate continuous pointer movement and command execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual plane space is divided into multiple operation spaces for different modes, then operation functionality is improved, but visual recognizability of boundary positions deteriorates
Solution Approach 1:
The patent applies color changes by displaying boundary positions between operation spaces using different colors or luminance levels. The display unit presents the virtual plane space with visual cues that highlight boundary positions, making them easily distinguishable to users. This allows users to recognize where mode transitions occur without adding physical markers, thus maintaining the virtual nature of the interface while improving visual recognizability.
2Ease of operation
If boundary positions are made visually recognizable, then user convenience is improved, but system complexity increases
Solution Approach 1:
The patent uses copying by creating a visual representation (aerial image) of the boundary positions that is projected onto the display. Instead of modifying the physical display device or adding complex hardware components, the system generates a digital copy or representation of the boundary positions that can be overlaid on the existing display. This approach improves user convenience through better visual cues while avoiding significant increases in physical system complexity.

AI summary
An interface system includes a detecting unit to detect a three-dimensional position of a detection target in a virtual space divided into a plurality of operation spaces, a position acquiring unit to acquire a three-dimensional position of the detection target detected by the detecting unit, a projecting unit to project an aerial image indicating a boundary position of each of the operation spaces in the virtual space, an operation space determining unit to determine an operation space including the three-dimensional position of the detection target on the basis of the three-dimensional position of the detection target acquired by the position acquiring unit and the boundary position of each operation space in the virtual space, and an operation information output unit to output operation information for executing a predetermined operation on a display device by using at least a determination result by the operation space determining unit.
