Velocity Gesture Speed Criterion for Input Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accurately conveying desired cursor movements on small input sensors in computing devices, as they often initiate velocity gestures unintentionally due to fast movements, leading to incorrect interactions.
Innovation Solution
Implementing a maximum speed criterion for velocity gestures, where the detection module identifies movements below a predefined maximum speed as fulfilling the velocity gesture criteria, and the initiation module only triggers the velocity gesture function when this criterion is met, distinguishing between intended gestures and fast flicks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If input sensor size is decreased to fit small computing devices, then device portability is improved, but gesture recognition accuracy deteriorates
Solution Approach 1:
The patent introduces a maximum speed parameter criterion to distinguish velocity gestures from fast flicks. By defining a threshold speed value, the system can differentiate between intentional gestures and accidental fast movements, thereby improving gesture recognition accuracy on small input sensors without increasing sensor size.
2Productivity
If velocity gesture detection sensitivity is increased, then gesture responsiveness is improved, but false gesture activation increases
Solution Approach 1:
The patent adds a maximum speed parameter as an additional criterion for velocity gesture detection. This parameter acts as a filter that prevents false activations from fast flicks while maintaining responsiveness to legitimate gestures that occur within the defined speed threshold.
Solution Approach 2:
The system continuously monitors movement speed and compares it against the maximum speed criterion, providing real-time feedback to determine whether a velocity gesture should be activated. This feedback mechanism helps distinguish between intended gestures and accidental fast movements.
