Wearable Device Touch Response Using Binocular Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices, such as smart watches, face challenges in providing accurate and real-time feedback for touch operations due to small screen sizes, leading to low control accuracy and inadvertent clicks.
Innovation Solution
A method and apparatus utilizing binocular recognition to acquire position information of a target fingertip within a set touch action occurrence area, determining a mapping point on the screen, and displaying a cursor to enable real-time feedback and improve touch accuracy by establishing a mapping relationship between the fingertip position and the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a small screen is used in wearable devices, then the device size is reduced and wearing comfort is improved, but touch accuracy and control precision deteriorate
Solution Approach 1:
The patent introduces spatial dimension by using binocular cameras to capture 3D fingertip position information, mapping it to the 2D screen coordinate system. This allows precise touch control without increasing screen size, resolving the contradiction between small device volume and high touch accuracy.
2Device complexity
If traditional touch screen is used, then device simplicity is maintained, but real-time feedback and control precision deteriorate
Solution Approach 1:
The patent implements real-time feedback by displaying a cursor that dynamically follows the mapped fingertip position on the screen. This visual feedback mechanism provides immediate confirmation of touch operations, improving control precision while maintaining relatively simple device architecture.
3Ease of operation
If finger touches the screen directly, then operation simplicity is maintained, but touch position accuracy deteriorates due to finger obscuring icons
Solution Approach 1:
The patent introduces a cursor as an intermediary element between the user's finger and the screen icons. The cursor serves as a visual mediator that indicates the exact touch position and target, allowing users to accurately select icons without the finger obscuring them, thus improving touch position accuracy while maintaining simple touch operation.
