Directional Sensing for Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with biometric authentication sensors face frustration due to delayed access to applications and actions after unlocking, as existing systems only facilitate authentication without enabling immediate actions based on swipe directions.
Innovation Solution
A directional sensing system that utilizes proximity sensors and a biometric authentication sensor to determine the swipe direction of an object, allowing the processor to perform actions on the electronic device, such as navigating applications, beyond mere authentication, by assigning swipe directions based on the order and nature of signals received from these sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication sensor is used for identification and access control, then security and authorization are improved, but user access speed and efficiency deteriorate because users must wait for unlocking process to complete before performing actions
Solution Approach 1:
The system performs preliminary authentication by detecting the object's presence and swipe direction before the formal unlocking process. The proximity sensors detect the object's approach and intended direction, allowing the system to prepare and execute actions (such as opening applications) during the swipe motion itself, rather than waiting for authentication to complete first.
2Measurement precision
If traditional biometric authentication system is used, then identification accuracy is improved, but operational versatility deteriorates because the system only supports authentication without additional navigational capabilities
Solution Approach 1:
The biometric authentication system is enhanced with multi-functionality by integrating proximity sensors that detect both authentication data and directional swipe gestures. The same sensor system serves dual purposes: verifying user identity through biometric data and determining swipe direction for navigational control, allowing a single interaction to simultaneously authenticate and perform actions such as opening applications or navigating interfaces.
3Adaptability or versatility
If additional input devices are added for navigational capabilities, then operational versatility is improved, but device complexity increases
Solution Approach 1:
The existing proximity sensors intended for authentication purposes are made multi-functional by programming them to also detect swipe directions. The same sensor array that captures biometric data for authentication simultaneously tracks the object's movement trajectory, eliminating the need for separate gesture-sensing hardware and maintaining device simplicity while adding navigational versatility.

AI summary
Systems and methods determine a swipe direction of an object on an electronic device to enable the performance of actions in response to the determined swipe direction. The swipe direction may be determined with respect to a biometric authentication sensor of the electronic device. According to certain aspects, signals that indicate the presence of an object may be received from proximity sensor(s) and/or a biometric authentication sensor. The swipe direction of the object may be determined based on the signals. An action may be performed on the electronic device in response to determining the swipe direction. An improved user experience of the electronic device may result through the use of these systems and methods.
