Stereo Video Observation Apparatus with Segmented Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereo video devices are expensive and can cause visually induced motion sickness, especially in young children and adults with developing or abnormal binocular vision, making it difficult to observe stereo video content without costly equipment and medical examinations.
Innovation Solution
A video observation apparatus using a simple configuration with a bottom portion, back sheet, top sheet, and front sheet, allowing for inexpensive production and distribution, and enabling users to observe stereo video using their own information processing terminals with a minimal lens and mirror unit setup, which can be easily gripped and used for long durations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive stereo video devices with polarization filters, shutter control mechanisms, or optical systems are used, then stereo video observation capability is achieved, but manufacturing cost increases and device complexity increases
Solution Approach 1:
The device is divided into separate functional sheets (bottom sheet, back sheet, top sheet, front sheet) that can be independently manufactured and assembled. Each sheet contains specific components (mirror on back sheet, lenses on front sheet) rather than integrating everything into a single complex unit, reducing manufacturing complexity while maintaining stereo observation capability
Solution Approach 2:
The apparatus is designed to work with any information processing terminal displaying stereo video content, making it a universal solution that doesn't require specialized expensive equipment. The simple optical system (mirror + lenses) can process any stereo video output from various devices, eliminating the need for proprietary expensive systems
2Duration of action of moving object
If users grip the video observation apparatus for extended periods, then observation duration increases, but hand fatigue increases and gripping stability decreases
Solution Approach 1:
The gripping surface is segmented into multiple distinct areas (bottom sheet for thumb, back sheet for fingers, top sheet for index/middle finger) that distribute the gripping force across different hand positions. This segmentation allows the hand to grip more naturally and comfortably over extended periods
Solution Approach 2:
Different sheets are positioned to provide optimal gripping surfaces at specific locations where hand contact occurs. The back sheet provides a stable base for fingers, the bottom sheet accommodates the thumb, and the top sheet supports the index and middle fingers, creating locally optimized gripping zones that reduce overall hand fatigue
3Strength
If the top sheet is positioned at full height for structural support, then structural strength is maintained, but material cost increases and ease of manufacture decreases
Solution Approach 1:
The top sheet is extracted from the full-height structural support role and repositioned lower. The back sheet assumes the primary structural support function, allowing the top sheet to be shorter and less expensive while still providing its necessary functions (lens mounting surface and gripping area)
Solution Approach 2:
The structural support function is merged into the back sheet, which is positioned to provide the necessary rigidity and strength. This allows the top sheet to be reduced in height without compromising overall structural integrity, as the back sheet compensates for the reduced top sheet height
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus allows for cost-effective and widespread observation of stereo video content, reducing the risk of visually induced motion sickness by distributing the gripping load and using inexpensive materials, while also enabling users to assess their suitability for stereo video viewing.
Implementation Method 1
a back sheet linked to one end of the bottom portion, and having a mirror portion on an inner surface of the back sheet opposing the information processing terminal
Implementation Method 2
a front sheet linked to the top sheet and having a lens portion positioned corresponding to the right and left eyes of the observer

AI summary
The present invention provides a video observation apparatus for observing video displayed on the display unit of an information processing terminal, comprising: a bottom portion on which the terminal is placed; a back sheet having a mirror portion on an inner surface of the back sheet opposing the terminal and arranged toward an observer to make an acute angle between the bottom portion and the back sheet; a top sheet arranged parallel to the bottom portion; and a front sheet having a lens portion positioned corresponding to the right and left eyes of the observer; wherein a height of the top sheet is offset downward from a height of the top of the apparatus formed by the back sheet; and wherein the apparatus is held by placing a thumb on the bottom portion, an index finger and/or a middle finger on the top sheet and the remaining fingers on the back sheet.
