A compact keyboard is -as the name says- compact: these keyboards don’t have a numeric part. The compactness of these keyboards bring a lot of advantages: the reach distance to the mouse is reduced and the strain on the muscles in the neck, shoulder and arm is reduced (less muscle tension). A compact keyboard makes it possible to work with the upper arms relaxed along the body (as opposed to a standard keyboard). The mouse can be positioned closer to the body, so one doesn’t adopt a ‘broad’ posture from the shoulders (which is accompanied by higher muscle tension). In this way, the chance of developing CANS complaints (Complaints to the Arm, Neck and Shoulders - formerly RSI) is reduced.
In most cases, users don’t miss the numeric keys that have been left out. Many people indicate that they hardly ever used these buttons in the first instance. Whether one misses these buttons or not depends on the work tasks one has to perform (depends on whether one has to do a lot of numerical work). Research from the Berliner Ergonomic Institute shows that 90% of users do not or rarely use the numerical part. Moreover, the number buttons are also processed a second time above the letter keys on the keyboard.
We have two different variants of compact keyboards in our product range: a wired and a wireless variant of the ErgoProof Compact Keyboard. All ErgoProof keyboards have a silver background with white keys. The keyboards are not provided with raised "legs": the upright position of a keyboard stimulates a position of the hand, whereby the back of the hand is moved towards the wrist. Given that this position is associated with a high level of muscle tension, this is not recommended.
