Stereoscopic Display Depth Adjustment for Tool Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic display devices cause a mismatch in the sense of distance between real and virtual objects, leading to an unpleasant user experience when objects in real space interact with stereoscopically displayed objects, resulting in visual inconsistencies such as foreground objects being hidden by background objects.
Innovation Solution
An information processing apparatus with a determination unit to detect the spatial position of an operating tool relative to the display surface and a control unit that adjusts the depth position of stereoscopic images to prevent overlap, ensuring the image is displayed at a position that aligns with the user's perspective, thereby reducing odd feelings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stereoscopic display is used to create depth perception, then the sense of three-dimensional space is improved, but visual mismatch occurs between real objects and virtual objects
Solution Approach 1:
The patent applies dynamics by making the display object's depth position adjustable and changeable based on operating tool position. The control unit dynamically adjusts the depth position of the display object in the stereoscopic space according to the detected position of the operating tool, allowing the system to adapt to different interaction states and maintain visual consistency throughout the interaction process.
Solution Approach 2:
The patent uses the operating tool as an intermediary element between the user and the stereoscopic display. The determination unit detects the operating tool's position, and the control unit uses this information to mediate the depth positioning of display objects, creating a bridge that connects real-space interaction with virtual-space representation and resolves the visual mismatch.
2Measurement precision
If the operating tool approaches the display surface, then interaction precision is improved, but the operating tool may overlap with display objects causing visual inconsistency
Solution Approach 1:
The patent applies preliminary anti-action by proactively adjusting the depth position of display objects before the operating tool actually overlaps with them. When the determination unit detects that the operating tool is approaching the display surface within a threshold distance, the control unit preemptively modifies the depth position of display objects in that region, preventing potential visual inconsistency before it occurs.
Solution Approach 2:
The system dynamically responds to the operating tool's approach by continuously monitoring its position and adjusting display object depths in real-time. This dynamic adjustment allows the system to maintain visual consistency while preserving the user's ability to precisely interact with the display surface.
3Reliability
If the depth position of display objects is adjusted dynamically, then visual consistency is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback by using the determination unit to continuously detect the operating tool's position and feeding this information back to the control unit. The control unit then adjusts the depth position of display objects based on this feedback, creating a closed-loop control system that maintains visual consistency through continuous monitoring and adjustment.
Solution Approach 2:
The system performs self-service by automatically detecting the operating tool's position and autonomously adjusting the depth positions of display objects without requiring manual intervention. The determination unit and control unit work together to self-regulate the stereoscopic display configuration, reducing the need for complex external control mechanisms.

AI summary
An apparatus and method provide logic for processing information. In one implementation, an apparatus may include a determination unit configured to determine a first spatial position of a portion of an operating tool disposed within a threshold distance of a surface of the determination unit. The first spatial position may be determined relative to the determination unit surface in a depth direction. The apparatus may also include a control unit configured to generate a first signal to display a stereoscopic image to a user at a first display position. The first display position may be disposed within a predetermined distance of the first spatial position.
