Bakker Elkhuisen's S-board 840 Ergonomic Numeric Keypad is the perfect complement to the S-board 840 Ergonomic Keyboard (not included, pictured below)-- an ideal accessory for users who want a compact keyboard but need a numeric pad for data entry. It connects easily via either your computer's USB port (or links through the 840 Keyboard's USB port).
We've tested both exhaustively in our ErgoLab and have found that the Keypad is one of the best numeric keyboards on the market for a number of reasons: you can store it away and save desk space when not working in numeral-heavy data input, it transforms very easily from a right-handed to a left-handed input simply by moving it and, perhaps the most clever, a switch transforms the keyboard into a full-function calculator with basic memory functions and 8-character LCD output. We delighted at moving our clunky old calculators off the desk and into the drawer--this one is much easier to use and certainly is more aesthetically pleasing!
Compatible: Pair with the S-board 840 or the UltraBoard 940 compact keyboard.
Including: Calculator functionality.
Smart: Extendable USB cable.
A compact keyboard does not have a numeric pad. For this reason, the mouse can be placed closer to the keyboard. Research has shown that 90% of keyboard users seldom if ever use the numeric pad. Working with a compact keyboard results in greater comfort because it reduces the reaching distance to the mouse (Cook, C., et al., 1998). This puts less strain on the shoulder and forearm. Dark letters on a light background make them easier to read (ISO 9241), and contribute to increased productivity (Snyder, 1990).
