The Wave Keys Keyboard from Logitech features a wave-style layout that inclines slightly upward at the middle. The keys also sweep upward to the left and right to encourage a very limited reduction in ulnar deviation at the wrists. Unlike other keyboards of this style which offer a distinct separation of the keys along the center of the keyboard, there is no separation, which requires that the hands be brought to a central position that will require lateral deviation for most typists. As well, unlike other wave-style keyboards that fan the keys in a downward curve that mirrors the descending lengths of the ring and pinkie fingers, the Wave Keys sweep upwards across the entire alpha/numeric keys. This can lead to awkward stretching or repositioning of the entire hand for the ring and pinkie fingers to access the outer keys. Those with smaller hands will most likely find this reach even more significant. The rather rapid transition from the upward sweep of the alpha numeric keys to the level keys of the numeric keypad may also lead to regular ulnar deviation when transitioning back and forth from home row position to the numeric keypad or mouse.

The Wave Keys Keyboard features low-travel membrane switches which require a significant degree of force for activation. The keycaps are crowned and concave to assist in targeting but have a reduced horizontal and vertical pitch of 18.5mm (19.0mm is standard) which may leave some, especially those with larger hands and fingers, feeling crowded, especially with the upward sweep curving the keys inward towards each other. Included is an integrated 3.25" deep cushioned palm support with a cleanable surface. The righthand numeric keypad and repositioned navigation keys classify this keyboard as a compact financial keyboard despite a fairly significant 8.4" reach from home row to the right edge of the keyboard, something that should be taken into consideration when determining suitability.

The Wave Keys Keyboard is powered by two AAA batteries and is able to connect via either the included Wireless Logi Bolt receiver or via bluetooth.

This A-Style Slanted KeyCap Keyboard from Kensington employs specially-designed slanted keycaps arranged in an "A" pattern. This slanted "A" layout of the keys provides a psychological and visual cue to help typists reduce ulnar deviation, minimizing adaptation time. This keyboard features a traditional 103 key layout. The A-Style layouts can be viewed in greater detail on the Detailed Specifications page.
NOTE: These are "legacy" products and are equipped with PS/2 connections. Testing indicates that they may also function with some PS/2 to USB adapters.

The Ergonomic Touchpad Keyboard from Adesso features a fixed split design and a built in touchpad. It employs moderate resistance tactile membrane keyswitches to provide feedback while typing with the integrated GlidePoint touchpad eliminating the need for extended reach to the mouse on the right. All of the alpha-numeric keys are standard size, unlike many similar keyboards that have wider keys to create a more symmetrical appearance. This means that a consistent target is present for the fingers on all keys. The Function row of keys are half-height, to help reduce the depth of the keyboard footprint and across the top of the keyboard are 20 hot-key buttons providing one-touch access to Internet Browser and Media Controls, Sleep/Wake/Power, and Calculator/My Computer/Media Player/Email. The keycap legends are twice the size of standard legending, making this suitable where higher visibility is required.

While the keyboard does offer a split layout, the separation in the middle is quite limited when compared to other split keyboards, even earlier models from Adesso. The minimal separation limits the benefit that the split could otherwise provide. The splay is also less than most other fixed-splay keyboards, only around 24°. The minimal separation and the reduced splay will result in some degree of wrist deviation for all except those of very slender build. The Navigation Keys, and especially the Numeric Keypad are angled the opposite of the Alpha/Numeric Keys, with the result being that orienting the hand to these, especially the numeric keypad, will require either a noticeable degree of outward rotation of the shoulder, abduction at the elbow, or ulnar deviation at the wrist.

The Ergonomic Touchpad Keyboard includes an integrated sloping palm support. However these are solely composed of hard plastic that is fairly slippery, causing the heels of the hands to slip back off the keyboard - those with longer hands will find this more noticeable. As well, the depth of the supports is noticeably shallower than earlier Adesso designs, especially for the right hand, further increasing the potential of slippage occurring.
Both left and right Space Bar keys lack stabilization which leads to a variance in activation feel over the width of the spacebar. In addition, the Caps Lock, Shift, Enter and both Space Bar keys are recessed slightly lower than the other keys, permitting less travel. As a result all of these bottom-out earlier than the other keys, which can be disconcerting and break typing rhythm.

The left and right alpha-numeric key groupings also feature slightly differing angles and keycap elevation. The left has both a slightly steeper angle and greater keycap elevation from row to row than the right key group. While the variance is not pronounced there may be those who find it significant enough to affect their positional proprioception.

The Wireless Ergonomic Trackball Keyboard from Adesso features a fixed split design with integrated cursor control and clicking. It employs moderate resistance tactile membrane keyswitches to provide feedback while typing with the centrally-positioned 0.875" diameter trackball offering smooth and accurate cursor control while eliminating the need for extended reach to the mouse on the right or left. All of the alpha-numeric keys are standard size, unlike many similar keyboards that have wider keys to create a more symmetrical appearance. This means that a consistent target is present for the fingers on all keys.

The Adesso Tru-Form Media Fixed Split Keyboard has multimedia keys that make this keyboard a multi-featured keyboard that combines a host of Windows and Multimedia keys in a fixed split layout, making it reminiscent of the discontinued Microsoft Natural Multimedia Keyboard. This is identical to the TruForm PRO with the removal of the touchpad.

Available in both English and French Canadian layouts, the Microsoft Ergonomic Keyboard bears design similarities to the Microsoft Natural Ergonomic Keyboard 4000, retaining the gull-wing design that orients keys at varying angles, from a maximum 14° tent in the middle to a traditional "flat" or 0° by the time the outer alpha keys are reached. The left and right key groups are also splayed slightly outward to encourage a nominally more neutral alignment of the wrists. An unusually deep 4" palm rest is permanently affixed to the keyboard. This palm rest offers improved cushioning and presents a deeper and flatter profile than that on the Natural 4000, helping to reduce wrist extension. However, unlike the pad on the Natural 4000, the surface of the palm pad on the Microsoft Ergonomic Keyboard is permeable. As a result it cannot be cleaned in the same manner as the leather-like pads on the Natural 4000.'

The minimum key height on this keyboard is 0.75" off the surface on which the keyboard is placed (1.75" on the keys in the middle of the keyboard). This elevation may require individuals to either raise their seats to accommodate the height of the keyboard or to use a keyboard tray to lower the keyboard into their lap. The keyboard also includes a detachable palm lift that can be used to raise the front to create negative slope intended to encourage better wrist alignment. Use of this lifter may require further adjustments of seat or keyboard tray height because it adds almost a full inch of elevation to the middle of the keyboard and increases the risk of a "pinch point" being created on the underside of the wrists.

Please Note: Those familiar with the earlier Microsoft Natural 4000 Ergonomic Keyboard may find that the key action on the Microsoft Ergonomic Keyboard is significantly different that what they have experienced in the past. While the Natural 4000 developed a reputation for its crisp and consistent key response, this successor fails in that regard. Key response is less distinct, requiring more sustained force, and varies at random across the keyboard, with even directly adjacent keys having noticeably different "feel". The bottom row of keys (CTRL-ALT-EMOJI KEY etc.) is approximately 300% higher force than the letter keys just above this row. Due to this variance across the keys serious touch typists may find themselves with dropped keystrokes or that they are required to exert greater levels of force in order to ensure consistent typing, potentially resulting in tissue fatigue and damage to the fingers and hands.

The Microsoft Natural Ergonomic Keyboard 4000 is designed to assist users to achieve a more neutral and natural posture while doing data entry. The design orients keys at varying angles, from a maximum 14° tent in the middle to a traditional "flat" or 0° by the time the outer alpha keys are reached. The left and right key groups are also splayed slightly outward to encourage a nominally more neutral alignment of the wrists. The control housed between the splayed keys is for Zoom (not vertical scroll as many may assume). A lightly padded 3" deep leatherette palm rest is permanently affixed to the keyboard.

The minimum key height on this keyboard is 1" off the surface on which the keyboard is placed (2" on the keys in the middle of the keyboard). This elevation may require users to either raise their seats to accommodate the height of the keyboard or to use a keyboard tray to lower their keyboard into their lap. The keyboard also includes a detachable palm lift that raises the front to create a 7° negative slope intended to encourage better wrist alignment. Use of this lifter may require further adjustments of seat or keyboard tray height because it adds another full inch of elevation to the middle of the keyboard and increases the risk of a "pinch point" being created on the underside of the wrists.

This keyboard is available in two models, a standard US English model and a Unilingual French Canadian model

Please Note:Activation of the spacebar on the Microsoft Natural Ergo Keyboard 4000 may feel somewhat stiff or "sticky". If the spacebar is pressed at one edge, the resistance is noticeably higher than when pressing it in the middle - this is not a warranty related issue.
