Wearable Ring Accessory Gesture Detection for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users wearing mobile devices on their wrists face difficulties in interacting with the device due to its location, such as detecting gestures and issuing commands, as the device may be unable to accurately determine hand signals or motions.
Innovation Solution
A wearable accessory, such as a ring, that communicates with the mobile device to expand its functionality and improve user interaction by detecting motions and gestures, allowing users to issue commands and receive alerts through audible, visible, and vibrational signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile device is worn on wrist, then device is always accessible and wearable, but gesture detection accuracy deteriorates
Solution Approach 1:
The system segments the interaction functionality between the mobile device (wrist-worn) and a separate accessory (ring or handheld). The mobile device handles computation and communication, while the accessory captures gestures and biometric data, allowing each component to optimize its specific function.
Solution Approach 2:
The accessory acts as an intermediary device between the user's natural gestures and the mobile device. It captures hand motions, gestures, and biometric information, then transmits this data to the mobile device for processing, enabling accurate gesture recognition without requiring the mobile device itself to be positioned for optimal detection.
2Weight of moving object
If mobile device is worn on wrist, then device portability is improved, but command issuance and interaction difficulty increases
Solution Approach 1:
Interaction functions are segmented between the compact mobile device and a separate accessory. The accessory (ring or handheld) serves as an extended control interface, allowing users to issue commands through gestures captured by the accessory rather than manipulating the small wrist-worn device.
Solution Approach 2:
The system adds a new dimension to interaction by introducing a separate accessory device that can be manipulated in three-dimensional space. This allows for more natural and varied gesture-based commands compared to limited input methods on a wrist-worn device.
3Adaptability or versatility
If accessory is added to mobile device, then functionality and gesture detection are improved, but device complexity increases
Solution Approach 1:
The system divides functionality between the mobile device and a separate accessory, allowing the accessory to contain specialized sensors (motion, biometric) while the mobile device handles processing and communication. This segmentation avoids consolidating all complexity in one device.
Solution Approach 2:
The accessory is designed as a universal interface that can work with multiple mobile devices through wireless communication. It provides multiple functions including gesture detection, biometric sensing, and notification delivery, reducing the need for device-specific implementations.

AI summary
In one embodiment, an apparatus is provided that includes a ring, a detector, a processor, and a transmitter. The ring is configured to be worn on a finger. The detector, disposed within the ring, is operable to detect a motion associated with the finger. The processor, communicatively coupled to the detector, is operable to determine, based at least upon the motion, that a command should be sent to a mobile device. The transmitter, communicatively coupled to the processor, is operable to communicate the command to the mobile device.
