Floating Image Position Control Using User Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems fail to position floating images appropriately for the user, leading to suboptimal viewing experiences.
Innovation Solution
An image display system that includes a floating image display unit, a sensor unit to detect user position and gestures, and a control unit to adjust the image display position based on user detection information and gestures, ensuring the floating image is displayed at a position suitable for the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a floating image display device forms a real image without user position detection, then the device structure is simple, but the image formation position is not appropriate for the user
Solution Approach 1:
The control unit pre-establishes the relationship between user position and optimal image formation position. By detecting user position in advance and calculating the appropriate display position before image formation, the system ensures the floating image appears at a location suitable for the user without requiring complex real-time adjustments during operation
Solution Approach 2:
The sensor unit continuously detects user position and provides feedback to the control unit, which adjusts the image formation position accordingly. This closed-loop feedback mechanism ensures the floating image is always displayed at an appropriate position relative to the user's location, improving ease of operation while managing device complexity through systematic control
2Adaptability or versatility
If the floating image is displayed at a fixed position, then the device structure is simple, but the display position cannot be tailored to individual users
Solution Approach 1:
The system transitions from a fixed image formation position to a dynamic position that adapts to each user's location. The control unit calculates and adjusts the optimal display position based on real-time sensor data about user position, enabling the floating image to be displayed at different locations for different users while maintaining manageable device complexity through algorithmic control

AI summary
An image display system includes a floating image display unit that displays a floating image as a real image in a predetermined displayable region in a three-dimensional space, a sensor unit that detects a user in the vicinity of the displayable region and outputs detection information, and a control unit that identifies a gesture, including at least one of body part movement and posture of the user, based on the detection information, and when the gesture is a predetermined position designation gesture designating a display position of the floating image in the displayable region, controls the floating image display unit so that the floating image is displayed at a designated display position as the display position designated by the position designation gesture.
