## Why It Matters  
When introduced around 1999, the Logitech Cordless Wheel Mouse represented a convergence of emerging wireless technology and ergonomic input design. By eliminating the cord, it gave users greater desk freedom and reduced cable clutter—a notable shift from the dominant wired mice of the era. Its inclusion of a scroll wheel added a new dimension of navigation efficiency, allowing users to scroll through documents and web pages without moving the mouse physically. Powered by standard AAA batteries, the device offered a practical, low‑maintenance power solution. As a ball‑based mouse, it retained the reliable tracking method of its predecessors while pioneering cordless convenience, influencing subsequent generations of wireless mice that moved toward optical and laser tracking.

## Notable For  
- Early adoption of **radio‑based wireless** connectivity in a consumer mouse.  
- Integration of a **scroll wheel** at a time when many mice still lacked this feature.  
- Use of **standard AAA batteries**, simplifying power replacement.  
- Being a **ball‑mouse subclass**, it bridged traditional tracking technology with emerging wireless trends.  
- Produced by **Logitech**, a leading peripheral manufacturer, adding credibility and market reach.

## Body  

### Overview  
The Logitech Cordless Wheel Mouse is a **computer mouse model** released circa 1999. It belongs to the broader class of **ball mice**, which detect motion through a rolling ball contacting internal rollers.

### Technical Specifications  

- **Wireless technology:** Radio communication (no cable).  
- **Power:** Two AAA batteries (specified as the source of energy).  
- **Buttons:** Three push‑buttons (as indicated by the “has_part” entry for push‑button with qualifier P1114 = 3).  
- **Scroll wheel:** Included as a distinct component (has_part entry).  
- **Brand & manufacturer:** Logitech (both brand and manufacturer fields).  

### Power and Connectivity  

- The mouse draws power from **two AAA cells**, a common and easily replaceable battery type.  
- Radio signals transmit cursor movement, button clicks, and wheel rotations to a compatible receiver plugged into the computer’s USB or PS/2 port.  

### Physical Design  

- Retains the **ball‑tracking mechanism** typical of pre‑optical mice, providing reliable movement detection on a variety of surfaces.  
- The **scroll wheel** sits between the left and right buttons, enabling vertical scrolling without moving the mouse.  
- **Three push‑buttons** are positioned for left‑click, right‑click, and a middle‑click function, matching the standard layout of contemporary mice.  

### Historical Context  

- In the late 1990s, most consumer mice were wired and relied on mechanical ball tracking.  
- Logitech’s Cordless Wheel Mouse combined **wireless convenience** with a **scroll wheel**, a feature that was still gaining adoption across software interfaces.  
- Its release contributed to the broader industry shift toward **cordless input devices**, paving the way for later optical and laser‑based wireless mice.
