Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality devices face limitations in user input methods, including battery life reduction, high costs, unreliable hand gesture recognition, and limited intuitive interaction due to the need for cameras and complex hand gestures, as well as restricted touch interfaces that limit user input options.
Innovation Solution
A virtual reality headset device with a touch interface on its front surface, allowing users to perform intuitive interactions by mapping touch gestures to corresponding locations on a display screen based on predetermined eye positions, enabling a wide range of gestures and improved security through dynamic keyboard layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hand gesture recognition using cameras is used, then user input capability is improved, but battery life is reduced and device cost increases
Solution Approach 1:
The patent extracts the touch interface function from the back of the device and places it on the front surface, allowing direct interaction without requiring camera-based hand gesture recognition. This eliminates the need for complex camera systems and associated computational resources, thereby preserving battery life while maintaining versatile input capability.
Solution Approach 2:
The patent creates a virtual representation of the display screen on the front touch interface, allowing users to interact with a copy of the interface elements directly on the front surface. This copying approach enables intuitive interaction without requiring complex gesture recognition algorithms, reducing computational overhead and energy consumption.
2Adaptability or versatility
If hand gesture recognition using cameras is used, then user input capability is improved, but device cost increases
Solution Approach 1:
The patent removes the requirement for camera systems and gesture recognition hardware by extracting the interaction function to the front touch interface. This simplification reduces component costs and manufacturing complexity while maintaining full input capability through direct touch interaction with virtual elements displayed on the front surface.
3Ease of operation
If touch interfaces are positioned on conventional locations, then device structure is simple, but user interaction intuitiveness is reduced
Solution Approach 1:
The patent inverts the conventional touch interface positioning by placing it on the front surface of the device rather than on the back. This allows the touch interface to be co-located with the display screen in the user's field of view, creating an intuitive spatial relationship where touch actions directly correspond to visual feedback without requiring the user to look away or adjust head position.
4Adaptability or versatility
If conventional touch interfaces with limited gestures are used, then device complexity is reduced, but user input options are limited
Solution Approach 1:
The patent implements a universal touch interface on the front surface that can recognize and respond to multiple types of gestures including taps, swipes, pinches, and long presses. The interface maps these gestures to corresponding actions on virtual elements displayed on the front, providing diverse input options without requiring separate specialized interfaces or complex additional hardware.
