Concave key wells
Concave key wells reduces hand and finger extension. Extension occurs when the joints in your fingers curl up and extend forward from your hands rather than relaxing down slightly in the direction of the palms. A flat typing surface assumes that your fingers are all of the same length, thus your longer fingers must arch up over the keys. The result is extension of the muscles and tendons in your hands. Your muscles do not operate at maximum efficiency and the result is more rapid muscle fatigue.

Concave key wells reduce extension by accommodating the various lengths of your fingers and placing your hands and fingers in a more relaxed and neutral position.

Vertical key layout
Keys are arranged in vertical columns to reflect natural motions of your fingers, and the keypads are sculpted and concave to fit the varying lengths of your fingers.

Closer placement of function keys
Soft-touch function keys are positioned closer to the alphanumeric keys to reduce awkward motions and stretches, particularly for key combinations involving thumb keys (Control and Alt, for example).

20-degree lateral tilt design
The keyboard design places your hands so that your thumbs are positioned approximately 20 degrees higher than pinky fingers. This design helps to minimize stresses associated with pronation and static muscle tension while enabling maximum keying productivity.

Integral palm support
The palm support with optional self-adhesive pads enhances comfort and reduces stressful extension of your wrist. This provides a place to rest your hands while they are not actively keying.

Cherry MX (Brown) Low-force, tactile key switches
The standard Advantage contoured keyboard utilizes the Cherry MX low-force tactile switch (brown stem). It is a semi-custom low force tactile design created in 1992 to Kinesis’ specifications. “Tactility” is a slightly elevated force around the midpoint of the stroke of the key which lets you know the switch is about to be activated. A tactile response is preferred by many ergonomists, because it cues your fingers that activation is about to occur and is thought to reduce the likelihood or incidence or “bottoming out” the switch with a hard impact. The peak (tactile) force is ~55gm, following by an activation force of ~45 gm.

Embedded 10-key layout
A traditional numeric (10-key) keypad is embedded into the right alphanumeric keywell, which provides ergonomic advantages for number-intensive operations. The 10-key legends are located on the front edge of the key caps. The 10-key can also be programmed to operate from the left keywell.

Key re-mapping
Individual keys can be re-mapped or copied to other key locations. As a result, you can customize the keyboard’s operation for your personal use to reduce stressful reaches and establish an optimal hand workload.

Macro programmable
Up to 48 macros can be programmed and stored in the keyboards on-board memory. Great for eliminating awkward key combinations or for individuals that type the same word or phrase repeatedly.

Optional foot switches
Up to three foot switches can be used to perform keystrokes, redistributing a portion of the workload away from your hands. For instance, a foot switch can be used to activate the embedded 10-key pad or “shift” key.

Smaller footprint
Another benefit of the embedded 10-key is that reduces the overall width of the contoured keyboard measuring only 16 5/8 inches x 8 1/8 inches x 3 inches making it much smaller than a traditional keyboard. This smaller foot print allows closer placement of any pointing device reducing over-reach issues.
