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 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 Ergonomic Desktop keyboard from Solidtek offers an advanced ergonomic layout in a compact narrow-footprint keyboard. The keys feature a variable tenting that subtly reduces forearm pronation, the inner keys having a slightly greater tenting angle that then reduces to almost level for the outer rows. The key layout is also splayed outwards, aligning the key orientation to better match the natural position of the hands and thereby encourages individuals to maintain a more neutral wrist alignment.

Unlike other one-piece keyboard designs that may offer a similar tenting and splay of the keys, the Ergonomic Desktop keyboard eliminates the numeric keypad from the layout. This addresses the issue of being forced to overreach on the right to access the mousing device, a common issue that can arise when the extra splay is added to the keyboard. The elimination of the numeric keypad reduces the required reach to the mouse by at least 3-4", which can significantly lessen the risk of developing shoulder problems arising from repetitive overreaching to the mouse.

The incorporated firm palm rest assists in maintaining better keyboarding posture by ensuring that the wrists can only be lowered to a point of limited extension. In addition, this keyboard is equipped with front legs that can be deployed to create a slight negative inclination of the keys, completely eliminating wrist extension.

The Ergonomic Desktop keyboard is equipped with full-travel membrane keyswitches that require a firm touch for activation. The keycaps are a chiclet-style with a very slight concave surface to aid in maintaining finger position.

Le Ergonomic Desktop keyboard de Solidtek offre une disposition ergonomique avancée dans un clavier compact plus étroit. Les touches ont une tente variable qui réduit subtilement la pronation de l'avant-bras, les touches intérieures ayant un angle de tente légèrement plus haut qui se réduit à presque niveau pour les touches extérieures. La disposition des touches est également ébrasé vers l'extérieur, ce qui encourage les utilisateurs à maintenir un alignement des poignets plus neutre en alignant l'orientation des touches pour mieux correspondre à la position naturelle des mains.

Contrairement à d'autres claviers un-morceau qui peuvent offrir une tente et de touches ébrasé semblable, l`Ergonomic Desktop keyboard élimine le pavé numérique de la disposition. Cela permet de résoudre le problème de s`étirer trop à la droite pour chercher la souris, un problème commun qui s`empire lorsque les touches sont ébrasés. Cela réduit la distance d'au moins 3-4po pour chercher la souris, ce qui peut réduire considérablement le risque de développer des problèmes d'épaule qui se produit avec des mouvements répétés de s`étendre pour la souris.

Le repose-poignets intégré aide les utilisateurs à maintenir une meilleure posture durant la dactylo assurant qu'ils ne puissent abaisser leurs poignets que jusqu'à un point d'extension limité. De plus, les pieds sous le devant du clavier peuvent être utiliser pour créer une légère inclinaison négative des touches, éliminant ainsi complètement l'extension des poignets.

L`Ergonomic Desktop keyboard a des interrupteurs à membrane à course longue qui nécessitent la pression ferme pour l'activation. Les capuchons des touches sont de type chiclet avec une très légère surface concave pour aider les utilisateurs à maintenir la position des doigts sur les touches.

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.

The CLEAVE Keyboard features the Truly Ergonomic split design to achieve a natural typing position. This non-traditional and slightly separated fixed-splay key layout aids in achieving a neutral wrist alignment by orienting the keys closer to the natural inward angle of the forearms and hands when using the keyboard.

Unlike traditional keyboards where the rows are offset horizontally, the CLEAVE features a columnar layout, with each column adjusted vertically to optimize key positioning by matching the length and reach of each finger, with the keycaps of each row being individually sculpted to optimize finger contact. The symmetrical layout also encourages a natural ergonomic central positioning of the keyboard.

In order to reduce the strain on the weaker pinky fingers, the most commonly used keys like Backspace, Delete, Shift, and Enter, are positioned centrally to be activated using the index fingers and thumbs. This also reduces awkward reaches that can reduce typing speed.

The CLEAVE is also the first keyboard to incorporate Optical Infrared Mechanical Switches and features a minimalist, almost flat design. Rather than keys being recessed into a housing, it features a base that houses the PCB, with the keys rising above the machined aluminum housing. The integrated self-skinned polyurethane palm supports are easily cleaned and help to reduce wrist extension while providing a cushioned rest for the palms.

The CLEAVE Keyboard is first and foremost an ergonomically-focused high-performance keyboard. However, the compact footprint achieved with the modified key layout and elimination of the numeric keypad also results in an overall width of just 13.6", reducing the reach for a mouse on the right by several inches and significantly lowering the risk of shoulder issues arising from overreach. This combination of high performance mechanical keyswitches, advanced ergonomic layout, quality structural design, and compact dimensions make this keyboard stand out from the crowd.

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.
