Computer mice and trackballs are pointing devices that translate human motion into digital input for computer systems. Mice detect two-dimensional motion via a sensor or ball, while trackballs use a stationary ball manipulated by fingers or palm. These devices remain critical for precise input in computing despite advancements in touchscreens and voice recognition.
| Type | Functional Features | Application Examples |
|---|---|---|
| Optical Mouse | Uses LED sensor for motion tracking | Office productivity, basic computing |
| Laser Mouse | High-precision infrared laser sensor | Graphic design, gaming |
| Wireless Mouse | Bluetooth/RF connectivity, rechargeable battery | Presentations, portable devices |
| Vertical Mouse | Ergonomic upright design | Medical rehabilitation, RSI prevention |
| Trackball | Stationary ball with optical sensors | CAD design, industrial control panels |
Typical mouse contains: optical/laser sensor module, microcontroller, left/right buttons with mechanical switches, scroll wheel with encoder, PCB assembly, and USB/Wireless dongle interface. Trackballs feature precision ball bearings, dual optical sensors for X/Y-axis detection, and pressure-sensitive click pads. Advanced models integrate RGB lighting, programmable buttons, and tilt-scroll mechanisms.
| Parameter | Importance |
