XR Virtual Keyboard Tactile Feedback for Touch Typing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Extended Reality (XR) environments, users face inefficiency in information input as they need to constantly look at the virtual keyboard to select and trigger virtual keys, preventing touch typing and reducing input efficiency.
Innovation Solution
The method involves presenting a virtual keyboard in an XR space, detecting the position and action of a user's finger relative to the keyboard, and outputting vibration signals to indicate the finger's position and actions, allowing users to input information without visual attention, thereby developing a touch typing habit and enhancing input efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users constantly look at the virtual keyboard to select and trigger virtual keys, then key selection accuracy is improved, but input efficiency deteriorates due to inability to develop touch typing skills
Solution Approach 1:
The patent applies feedback by providing real-time vibration signals to the user based on finger position and key press actions. The vibration feedback mechanism allows users to sense key positions and press confirmations through tactile sensation, enabling accurate key selection without visual attention, thus resolving the contradiction between selection accuracy and input efficiency
2Measurement precision
If visual attention is required for keyboard interaction, then key position discrimination is improved, but touch typing skill development deteriorates
Solution Approach 1:
The patent replaces the visual-mechanical interaction system with a tactile-vibration feedback system. By substituting visual detection with vibration-based tactile feedback, users can discriminate key positions through touch rather than sight, enabling touch typing skill development while maintaining position discrimination accuracy
3Adaptability or versatility
If vibration feedback is provided for key position and action confirmation, then touch typing skill development is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a vibration feedback mechanism that serves multiple functions: indicating key position, confirming key press actions, and guiding touch typing learning. This multi-functional approach enables touch typing skill development without requiring separate complex systems for each function, thus managing device complexity while improving adaptability
