Smart Ring Gesture Control for Touchless Mobile Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent mobile devices are difficult to operate in specific circumstances, such as when a user is unable to touch the screen, e.g., during presentations or emergencies, limiting their functionality.
Innovation Solution
A wireless controlling system using a smart ring that detects hand gestures to send corresponding commands to the mobile device, allowing users to control their devices without physical interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen interface is used for controlling mobile devices, then ease of operation is improved for normal use, but the device becomes unusable when the user cannot touch the screen (e.g., during presentations or emergencies)
Solution Approach 1:
The patent introduces a gesture recognition system as an intermediary control method. Instead of requiring direct touch interaction with the screen, the system mediates control through gesture detection via sensors (accelerometers, gyroscopes, cameras) that capture hand movements and translate them into device commands. This allows users to control the device without physical contact, solving the contradiction between touch-based ease of operation and adaptability to non-touch scenarios.
2Adaptability or versatility
If gesture recognition technology is added to enable touchless control, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional components in mobile devices to implement gesture recognition. The same sensors already present for other purposes (accelerometers for step counting, gyroscopes for screen rotation, cameras for photos) are repurposed to detect hand gestures. By making these existing components serve multiple functions, the system adds touchless control capability without significantly increasing device complexity.
Solution Approach 2:
The gesture recognition system utilizes the device's own existing hardware resources (sensors, processors, cameras) to provide the additional functionality of touchless control. Rather than requiring entirely new dedicated components, the system makes the device's existing capabilities serve the dual purpose of both their original functions and gesture detection, thereby minimizing the increase in device complexity while achieving improved adaptability.

AI summary
A wireless controlling system including a smart ring (1) and an identification program (241) installed in a mobile device (2) is disclosed. The ring (1) includes an MCU (11), a six-axis accelerometer (12), a transmitting unit (13), and a storage (14). The storage (14) stores multiple gesture models (141) respectively corresponding to different moving trajectories (4). When a user (3) moves with the ring (1), the six-axis accelerometer (12) continuously detects a set of moving signals of the ring (1). The MCU (11) continuously determines whether the set of moving signals matches any moving trajectory (4) of the gesture models (141). When a gesture model is matched, the MCU (11) sends a gesture command corresponding to the matched gesture model to the mobile device (2) through the transmitting unit (13). The mobile device (2) analyzes the gesture command to obtain a corresponding operation command through the identification program (241), and the mobile device (2) is being controlled to execute a corresponding function in accordance with the operation command.
