UltraBoard 950 is the latest compact keyboard from BakkerElkhuizen. The light keystroke, 2 USB ports and clear layout make this a complete keyboard.
The biggest difference to a standard keyboard is that it has no numerical section, which makes the keyboard narrower.
A compact keyboard reduces the distance to the mouse and reduces strain on your lower arms. An added benefit is that a compact variant is easier to transport in a laptop bag. You therefore need not rely on your laptop keyboard.
A compact keyboard lacks the numerical section. The mouse can thus be placed closer to the keyboard. Research shows 90% of users rarely or never use the numerical section. A compact keyboard is more comfortable because it reduces the distance to the mouse (Cook C, et al. , 1998). It thus reduces strain on the lower arms and shoulders. Dark letters on a bright background improve legibility (ISO 9241) and contribute to higher productivity (Snyder, 1990).
