Wrist-Worn Authentication Using Same-Hand Finger Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication methods for wearable devices, such as smart watches, require the use of the opposite hand, which can be inconvenient and cumbersome, especially when the other hand is busy.
Innovation Solution
A wearable computer device equipped with sensors and a user authentication module that allows same-hand authentication by analyzing finger movements over a virtual grid, enabling users to authenticate themselves using the hand wearing the device, without the need to use the opposite hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods (passwords, PIN, patterns) are used on wearable devices, then user authentication can be achieved, but the user must use the opposite hand which reduces ease of operation and increases user effort
Solution Approach 1:
The system uses the hand wearing the device itself to perform authentication gestures, eliminating the need to use the opposite hand. The wearable device detects gestures from the same hand that is already positioned for natural interaction, making authentication a self-service operation that does not require additional manual effort or coordination between hands
2Reliability
If the user's other hand is busy, then the user cannot perform authentication gestures, but authentication is still required to access the device
Solution Approach 1:
The authentication system is designed to work with the hand that is already wearing the device, allowing users to authenticate even when their other hand is occupied with tasks. The same hand that wears the device can perform the authentication gesture without requiring the user to stop or slow down their primary task
3Reliability
If authentication requires the opposite hand, then security can be maintained, but extra user effort and time are required
Solution Approach 1:
The system enables authentication using the same hand that wears the device, eliminating the need to switch hands or coordinate between hands. This reduces the time and cognitive effort required for authentication while maintaining security through gesture recognition algorithms that verify authentic user actions
4Ease of operation
If same-hand authentication is implemented, then ease of operation is improved, but the system complexity increases due to sensor data processing
Solution Approach 1:
The system replaces complex mechanical interaction requirements with sensor-based gesture detection. Instead of requiring precise manual coordination between hands, the system uses accelerometers, gyroscopes, and other sensors to detect and interpret gestures from the same hand, converting physical movements into digital signals for authentication verification

AI summary
Apparatuses, methods and storage medium associated with same hand user authentication are disclosed herein. In embodiments, an apparatus, wearable on a user's wrist, may include a user authentication module to authenticate and grant access to the user. To authenticate the user, the user authentication module may be configured to receive sensor data indicative of movements of one or more fingers over a virtual grid, analyze the sensor data to determine the movements, and authenticate and grant the user access or deny the user access to the apparatus based at least in part on a result of the analysis. The one or more fingers are fingers of a hand of the user that adjoins the wrist on which the apparatus is worn. In embodiments, the senor data may include sensor data collected by sensors configured to measure tendon/muscle positions of the wrist. Other embodiments may be disclosed or claimed.
