Logitech Comfort Wave 450 Manual

Delivering Comfort for Busy Professionals:
Comfort Wave Design and Negative Tilt from Logitech
It's easy to understand why improved comfort can directly result in improved productivity.
Data entry. E-mail. Instant messages. Presentations. Spreadsheets. Web searches. In
today's workplace, computers are the dominant platform through which work gets done.
As a result, more and more time is spent typing on a keyboard. According to a study
Harvard University conducted for Logitech (Dennerlein 2006), the average PC user
types 2 million keystrokes per year. The result can often be fatigue – and less effective
employees.
To improve comfort for busy professionals, Logitech for Business introduced the
Logitech® Comfort Wave 450 keyboard, which features the acclaimed Comfort Wave
Design, and – in a Logitech first – the innovative negative tilt.
The Comfort Wave Design: Cradling Fingers
To comfort tired hands and fingers, in 2007 Logitech introduced the Comfort Wave
Design. To enhance comfort without requiring that people change how they type,
Logitech combined three elements: an innovative wave key-frame design, a U-shaped
constant curve and a cushioned, contoured palm rest. In comparison to ergonomic
keyboards, the Wave keyboard can be used immediately – there's no learning curve.
In 2008, research confirmed that the Logitech Wave Keyboard "improves comfort"
(according to an independent study by Peter W. Johnson, Ph.D., of the University of
Washington).
The Logitech Comfort Wave Design combines the following three elements:
1. Wave key frame
The Comfort Wave Design features a gradual wave-shaped contour that cradles the
fingers with a shape that supports their actual, varied length. Because hands and
fingers can rest in a more natural position and keys are closer to fingertips, the Wave
key frame helps eliminate awkward hand and forearm positions, enhancing comfort
and improving productivity.
2. Constant curve design
The U-shaped constant curve features consistently sized keys that let people type
with confidence and comfort. The subtle 5-degree curve allows people's hands to
open up and take a natural position instead of forcing the wrists to bend. And
because each key is the same size and the same distance from one another, the
learning curve is minimal.
