Mouse Transducer Dynamic Sensitivity Control for Button-Induced Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Highly sensitive pointer devices, such as mice with advanced transducers, experience unintended displacement due to unintentional movement caused by button operation, affecting user experience and requiring methods to differentiate between intended and unintended movements without reducing sensitivity or terminating intended movements.
Innovation Solution
A method and system that detect switch activation, sample displacement during a defined interval, and determine displacement magnitude and rate to identify unintended movements, allowing intended movements to manipulate objects while impeding unintended ones, using a controller and transducer in a peripheral device system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high sensitivity transducer is used in mouse, then movement sensitivity is improved, but unintended displacement occurs during button operation
Solution Approach 1:
The system dynamically adjusts the operational state of the transducer based on switch activation status. When a button is pressed, the transducer is placed in a low-sensitivity or disabled state during the button press duration, preventing unintended displacement while maintaining high sensitivity during normal operation. This dynamic state change resolves the contradiction by making sensitivity adaptive rather than static.
Solution Approach 2:
The system detects switch activation in advance and preemptively reduces transducer sensitivity or disables movement detection during the button press interval. By anticipating the button press event and adjusting sensitivity before unintended movement occurs, the system prevents the harmful effect while preserving measurement precision during normal use.
2Object-affected harmful factors
If sensitivity reduction is applied to prevent unintended displacement, then unintended movement is reduced, but the purpose of using high sensitivity mouse is defeated
Solution Approach 1:
Rather than applying permanent sensitivity reduction, the system implements dynamic sensitivity adjustment that maintains high sensitivity during normal operation and temporarily reduces sensitivity only during button press intervals. This resolves the contradiction by making sensitivity context-dependent, preserving measurement precision when needed while preventing unintended displacement during button operation.
Solution Approach 2:
The system applies sensitivity reduction locally in time (only during button press intervals) and in specific operational contexts (when switch is activated), rather than globally across all operations. This localized application preserves the high sensitivity benefit for intentional movements while eliminating unintended displacement during button presses.
3Object-affected harmful factors
If all mouse movement is terminated after button operation, then unintended displacement is prevented, but intentional movements within the duration are also terminated
Solution Approach 1:
The system uses feedback from switch activation detection to intelligently control movement termination. Instead of blanket termination, the system selectively prevents movement only during confirmed button press intervals while allowing intentional movements outside these intervals. This feedback-based approach distinguishes between unintended movement during button presses and intentional movements, resolving the contradiction.
Solution Approach 2:
The system dynamically controls movement termination based on real-time switch state detection. Movement is terminated only during button press intervals when the switch is activated, while intentional movements occurring outside these intervals are permitted. This dynamic, conditional approach prevents unintended displacement without sacrificing intentional movement capability.

AI summary
Substantially elevated movement sensitivity of a mouse enables improved control and finer manipulation of an object, for example a pointer, displayed on a display device. However, the elevated movement sensitivity also results in unintended movement of the mouse, generated when a button of the mouse is operated, being translated into displacement of the pointer on the display device. An embodiment of the invention describes a method for transducing movement occurring during an interval into signals in response to the button being operated. The signals are for use in manipulating the object. The method is further for comparing properties of the displacement with pre-defined reference properties to determined whether the movement is intended or unintended. The signals are subsequently terminated to impede manipulation of the object when the movement is determined to be unintended to thereby correct the unintended movement.
