Solution Overview
Problem
Current human-machine interfaces are limited in their ability to detect intuitive and precise finger and hand gestures for controlling electronic devices, particularly in applications like virtual reality and augmented reality, where visual feedback is restricted.
Innovation Solution
A ring with integrated touch and proximity sensors that detect finger and hand gestures by analyzing the relative positions and movements of fingers, allowing for wireless communication to control devices without the need for traditional controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional controllers are used for device control, then device control functionality is provided, but control precision and intuitiveness are limited
Solution Approach 1:
The patent replaces traditional mechanical controllers (mice, keyboards, remote controls) with a ring-based human-machine interface that detects finger and hand gestures through touch and proximity sensors. This substitution enables more intuitive and precise control by directly sensing natural hand movements rather than requiring interaction with separate control devices.
Solution Approach 2:
The ring interface utilizes the user's own hand and finger movements as the control mechanism, eliminating the need for external controllers. The system detects gestures naturally performed by the user, making the control system serve itself through the user's inherent motor skills rather than requiring learning of artificial control schemes.
2Ease of operation
If visual feedback is provided for gesture control, then control accuracy is improved, but usability is restricted in environments where visual feedback is unavailable
Solution Approach 1:
The ring interface provides tactile feedback through the contact regions and haptic elements, allowing users to receive confirmation of their gestures without visual input. This alternative feedback mechanism maintains usability in environments where visual feedback is restricted or unavailable, such as virtual reality applications or low-light conditions.
3Adaptability or versatility
If multiple contact regions are integrated into the ring, then gesture detection capability is enhanced, but device complexity increases
Solution Approach 1:
The ring integrates multiple contact regions with touch and proximity sensors that can detect various finger and hand gestures, making a single device capable of numerous control functions. The same sensor array serves multiple gesture types, providing universal control capability across different applications without requiring separate specialized sensors for each gesture type.

AI summary
A ring for identify a gesture is provided. A user wears a ring on a first finger, in which the ring has a first contact region facing a second finger adjacent to the first finger, and a second contact region facing a third finger adjacent to the first finger. The first contact region is configured to detect a touch or proximity input from the second finger, and the second contact region is configured to detect a touch or proximity input from the third finger. Each of the first and second contact regions has one or more touch or proximity sensors. The user moves the first, second, and third fingers relative to each other. In response to a first finger and hand gesture, a touch or proximity input is detected at the first contact region but not at the second contact region. In response to a second finger and hand gesture, a touch or proximity input is detected at the second contact region but not at the first contact region. In response to a third finger and hand gesture, touch or proximity inputs are detected at both the first and second contact regions.
