The computer mouse is a fundamental input device used for navigation, selection, and control across operating systems and applications. Modern mice incorporate advanced sensor technologies, programmable buttons, ergonomics, and connectivity options that significantly enhance productivity for everyday users and provide precision, speed, and customization for gaming.
This Knowledge Base article provides a technical, practical overview of computer mouse technologies, features, and commonly used shortcut commands that improve efficiency in daily work and deliver performance advantages in gaming environments.
A computer mouse translates physical movement into cursor movement using an internal motion sensor. Input signals are processed by the operating system or game engine to perform actions such as clicking, dragging, scrolling, and macro execution.
Key technical components include:
Motion sensor (optical or laser)
Microcontroller (for processing input and macros)
Switches (mechanical or optical)
Connectivity module (USB, wireless receiver, Bluetooth)
Firmware/software driver
Uses LED light and CMOS sensor
Best for most office and general use
Works well on mouse pads and matte surfaces
Advantages
Accurate
Affordable
Low power consumption
Uses laser diode for tracking
Higher sensitivity (DPI)
Works on glossy and uneven surfaces
Advantages
High precision
Suitable for high-resolution displays
High polling rate (up to 8000 Hz)
No hardware acceleration
Raw input support
Advantages
Competitive gaming accuracy
Consistent tracking
USB connection
No latency or battery dependency
