Video Display Apparatus Gesture Switching with Identification Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users wearing non-transmission type video display apparatuses face difficulties in eating or drinking due to blocked outside views, and existing gesture recognition methods often result in unintended switching of video images.
Innovation Solution
A video display apparatus with a video display unit, an image pickup unit, and a switching control unit that selectively switches between a video image of content and an outside view image based on detection of a predetermined identification pattern and gesture, ensuring accurate and intended switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture recognition is used to switch video images, then users can eat or drink while viewing contents, but the video image may be switched at unintended timings
Solution Approach 1:
An identification pattern is introduced as an intermediary element that mediates between the gesture detection and video image switching. The pattern recognition unit detects this pattern in the captured image, and only when both the gesture and pattern are detected does the switching occur. This intermediary mechanism ensures that switching happens only at intended timings when the user is actually interacting with objects in the real world.
2Adaptability or versatility
If the video display apparatus blocks outside view, then users can be immersed in viewing contents, but users cannot see the outside environment to eat or drink
Solution Approach 1:
The video display apparatus dynamically switches between displaying contents and displaying the outside environment based on detected user gestures and identification patterns. The display is not static but adapts to user needs in real-time, transitioning from an immersive content-viewing state to an interactive eating/drinking state and back, thereby providing both immersion and practical functionality.
3Device complexity
If simple gesture detection is used for switching, then operation is simple, but unintended switching occurs due to false gesture recognition
Solution Approach 1:
The identification pattern serves as an intermediary verification layer between gesture detection and video image switching. Instead of relying solely on gesture recognition, the system requires both gesture detection and pattern recognition to confirm switching should occur. This dual-confirmation mechanism reduces false switching while maintaining operational simplicity.
Solution Approach 2:
The system provides visual feedback by displaying the captured image showing the detected identification pattern, allowing users to verify that the correct object is recognized before switching occurs. This feedback mechanism helps users understand the system's state and confirms that switching will happen at the intended timing.

AI summary
A video display apparatus according to an embodiment includes a video display unit configured to display a video image in a field of view of a user in a state in which the user is wearing the video display apparatus, an image pickup unit configured to take a video image of an outside state, a switching unit configured to selectively perform switching as to whether to display a video image of a certain content or a video image taken by the image pickup unit, and a switching control unit configured to control the switching unit. The switching control unit switches the video image displayed on the video display unit when an object with a predetermined identification pattern is included in the video image taken by the image pickup unit and the switching control unit has detected that a user's hand has made a predetermined gesture.
