Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture tracking technology is implemented to replace traditional physical input elements, then the intuitiveness and ease of operation are improved, but the complexity of the system increases and users require education and adaptation time
Solution Approach 1:
The patent introduces a virtual controller as an intermediary element that bridges gesture tracking technology and traditional controller interfaces. The virtual controller is rendered in the visual content and responds to hand gestures, providing a familiar controller-like interface that mediates between the user's natural gestures and the software's input requirements, thereby reducing the complexity burden on users while maintaining ease of operation
Solution Approach 2:
The patent creates a virtual copy of a traditional controller interface that is displayed within the visual content. This virtual controller copies the essential input elements and layout of physical controllers, allowing users to interact with familiar interface patterns while using gesture-based input, thus reducing the adaptation burden without sacrificing the benefits of gesture tracking
2Ease of operation
If a virtual input interface is introduced to bridge gesture tracking and traditional controller functions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the virtual controller interface with the visual content being displayed, integrating both elements into a unified rendering process. The virtual controller is rendered as part of the visual content rather than as a separate overlay, which combines multiple functions (visual display and input interface) into a single integrated system, thereby improving ease of operation while managing device complexity through consolidation
3Ease of operation
If the virtual input interface is moved along with the hand to maintain alignment, then the ease of operation is improved, but the computational requirements and processing time increase
Solution Approach 1:
The patent performs preliminary calculations of the virtual controller's position and orientation based on predicted hand movement trajectories. By pre-computing transformation matrices and positioning data before the hand actually reaches certain positions, the system reduces real-time processing requirements while maintaining smooth alignment between the virtual controller and the user's hand, thereby improving ease of operation without excessive processing time

AI summary
The embodiments of the disclosure provide a method for providing an input interface, a host, and a computer readable storage medium. The method includes: tracking a hand gesture of a hand; and in response to determining that the hand gesture of the hand indicates that the hand has performed a target gesture, displaying a virtual input interface in a visual content associated with a reality service, wherein the virtual input interface provides a controller-like function, and the virtual input interface is moved along with the hand.
