The Evoluent Left handed keyboard has its numeric keypad on the left side to provide more room for mouse use on the right.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).

This left handed keyboard layout helps to balance out the user’s workload, allowing the user’s left-hand to operate the numeric keypad while the right hand operates the mouse.
The ‘A-shape’ key layout encourages a more relaxed, natural wrist position which helps users to reduce ulnar deviation. The number pad is on the left side, reducing the work area for less strain and improved user comfort.
