System and method of adjusting mouse sensitivity

An information handling system comprising:

• a processor;
• a display communicatively coupled to the processor and configured to display a cursor;
• a mouse communicatively coupled to the processor, the mouse comprising:
• a mouse position sensor;
• a plurality of force sensors associated with the mouse, wherein each force sensor is configured for detecting a force value associated with the mouse;
• and
• a microcontroller unit (MCU) communicatively coupled to the mouse position sensor, the plurality of force sensors and the processor;
• and
• a memory medium coupled to the MCU, wherein the memory medium includes MCU instructions, which when executed by the MCU, cause the MCU to:
• receive a first set of mouse position values from the mouse position sensor;
• receive a second set of mouse position values from the mouse position sensor;
• determine a distance moved by the mouse and a mouse position value rate of change based on the first set of mouse position values and the second set of mouse position values;
• receive a set of force sensor values from the plurality of force sensors;
• compare the set of force sensor values with a force sensor threshold value stored in the MCU to determine an increase or a decrease in a sensitivity of the mouse
• wherein:
• if the set of force sensor values are less than the force sensor threshold value, the MCU instructions cause the MCU to:
• determine a user is trying to make a coarse adjustment of the cursor on the display;
• and
• send a first set of processor instructions to the processor such that movement of the mouse over the distance will cause the cursor to move over a first corresponding distance on the display based on the decrease in the sensitivity of the mouse;
• if the set of force sensor values are greater than the force sensor threshold value and the mouse position value rate of change is less than a mouse speed threshold, the MCU instructions cause the MCU to:
• determine the user is trying to make a fine adjustment of the cursor on the display;
• and
• send a second set of processor instructions to the processor such that movement of the mouse the distance will cause the cursor to move over a second corresponding distance on the display less than the first corresponding distance based on the increase in the sensitivity of the mouse.

A method for adjusting mouse sensitivity for a mouse communicatively coupled to a processor coupled to a display, the method comprising:

• receiving a first set of mouse position values from a mouse position sensor;
• receiving a second set of mouse position values from the mouse position sensor;
• determining a distance moved by the mouse and a mouse position rate of change based on the first set of mouse position values and the second set of mouse position values;
• receiving, by a microcontroller unit (MCU) associated with the mouse, a set of force sensor values from the plurality of force sensors associated with the mouse;
• comparing the set of force sensor values with a force sensor threshold value stored in the MCU to determine whether to increase or decrease a sensitivity of the mouse and;
• communicating with the mouse position sensor to determine if the mouse position is changing;
• if the mouse position value rate of change is greater than a mouse speed threshold, decreasing the sensitivity of the mouse and sending a first set of instructions to the processor such that movement of the mouse the distance results in the cursor moving a first corresponding distance on the display based on the decrease in the sensitivity of the mouse;
• and
• if the mouse position rate of change is less than the mouse speed threshold and a force sensor value of the set of force sensor values exceeds the force sensor threshold value, increasing the sensitivity of the mouse and sending a second set of instructions to the processor such that movement of the mouse the distance results in the cursor moving a second corresponding distance on the display based on the increase in the sensitivity of the mouse.
