The USB-C Wireless Aluminum Keyboard for PC from Matias reflects the same familiar design concepts and high quality that Matias has employed for many years. With a Black anodized aluminum upper housing, and equipped with high quality Matias scissor switches, this keyboard is designed for durability and to provide a responsive typing experience. Media control is achieved through alternate functions on the F7-F9 keys. The slim, low-profile design has a complimentary light weight of just 1.18 lbs.

Wireless 2.4 GHz connectivity on the USB-C Wireless Aluminum Keyboard for PC is provided through the world's smallest USB-C nano receiver. A high power, long-lasting 1600 mAh battery is able to provide up to 3 years of use between charges.

If more frequent charging and a plastic housing are not an issue the budget-friendly Wireless USB-C Keyboard for PC offers the same USB-C 2.4 ghZ wireless functionality with a smaller 500 mAh battery that can provide up to a year of use on a charge.

Note: Both the Matias Wireless USB-C Mouse and Wireless USB-C Pro Mouse can be connected simultaneously with the keyboard, using the same USB-C nano receiver so only a single port is required.

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 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 Wireless Ergonomic Trackball 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 Ergo K860 Keyboard from Logitech features a flowing design that orients keys at varying angles across the keyboard. The K860 alpha/numeric keys transition through a concave arc from almost level at the centre to about 5° at the right and left edges. The navigation cluster on the right then completes the transition to a fully flat numeric keypad. The left and right key groups are also angled or "splayed" outward to encourage adoption of a more neutral alignment of the wrists. The Ergo K860 also has an attached 3.5" deep cushioned palm support which rises up to match the keyboard elevation. This needs to be taken into consideration when deploying the K860 into a workstation.

While the K860 has a slender low profile the angled design results in the middle keys being elevated to 1.5". 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 is also equipped with front legs that can be used to raise the front to create either 4° or 7° negative slope intended to encourage better wrist alignment. Use of these legs may require further adjustments of seat or keyboard tray height because it adds another inch of elevation to the middle of the palm support and increases the risk of pressure points being created on the underside of the wrists.

The K860 features low-travel scissor switches with chiclet-style keycaps. Key activation is crisp and comparatively high force compared to other scissor switch devices and does require a significant degree of activation force. The low profile keycaps have a satin texture with a slight concave surface to aid in finger positioning.

L'Ergo K860 Keyboard de Logitech présente une forme fluide (flowing design) qui oriente les touches à différents angles sur le clavier. Les touches alphanumériques du K860 passent par un arc concave allant d'une position presque horizontale au centre à un angle d'environ 5° sur les bords droit et gauche. Le groupe de touches navigation situé à droite complète la transition vers un pavé numérique entièrement plat. Les groupes de touches gauche et droite sont également inclinés ou « ébrasser » vers l'extérieur pour encourager l'adoption d'un alignement plus neutre des poignets. L'Ergo K860 est également équipé d'un support de paume rembourré de 3.5po de profondeur qui se relève pour s'adapter à l'élévation du clavier. Cela devrait être tenu en compte lors de l'installation du K860 dans un poste de travail.

Tandis que le K860 ait un profil fin et bas, sa conception angulaire fait que les touches centrales sont surélevées de 1.5po. Cette surélévation peut obliger les personnes à surélever leur siège pour s'adapter à la hauteur du clavier ou à utiliser une tablette de clavier pour abaisser le clavier sur leurs genoux/cuisses. Le clavier est également équipé de pieds en avant qui peuvent être utilisés pour élever l'avant du clavier afin de créer une pente négative de 4° ou 7° prévu pour encourager un meilleur alignement du poignet. L'utilisation de ces pieds peut nécessiter d'autres ajustements de la hauteur du siège ou du tablette de clavier, car elle ajoute un pouce d'élévation supplémentaire au milieu du support de la paume et augmente le risque de créé des points de pression sur le dessous des poignets.

Le K860 a des interrupteurs à ciseaux avec distance court et des touches capuchons à chiclet. L'activation des touches sont significativement plus grande par rapport à d'autres dispositifs d'interrupteurs à ciseaux et nécessite une force d'activation significante. Les touches à profil bas ont une texture satinée avec une surface légèrement concave pour faciliter le positionnement des doigts.

The Keys-U-See USB large print keyboard is designed for those who have difficulty seeing the legends on a standard keyboard. This user-friendly large print keyboard also has 12 'hot keys' providing easy access to common functions.

It is a full size enhanced 104 key keyboard with standard layout, printed in big and bold 41 point typeface. It features high contrast colour keys in 3 color combinations: Yellow with Black Legends, Ivory with Black Legends, or Black with White Legends. The Wireless keyboard model also includes a wireless mouse.

Le concept du clavier Keys-U-See USB large print est pour les gens qu'y on de la difficulté voir les clés sur un clavier standard. Ce clavier avec des lettres imprimées gros est une service facilement accessible et a 12 'hot keys' qui vous donnes l'accès aux fonctions communs.

Il-y-a un élément de couleur avec grand contraste en 3 combinasions de couleures. Jaune avec la lettre en noir, blanc avec la lettre en noir, ou noir avec la lettre en blanc.

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.

The Kensington Pro Fit Ergo Wireless Keyboard features a winglike design that orients the alphanumeric keys at approximately 11° with the navigation and keypad keys being at 0°. This sloping of the keys reduces pronation of the hands and forearm while typing. The left and right key groups are also splayed outwards at 33° to encourage a more neutral alignment and reduce ulnar deviation at the wrists. The integrated palm support on the Pro Fit Wireless Keyboard is just over 3" in depth, and offers cushioning for the palms. It is covered in a leatherette material that is easily cleaned.

The angle and height of the Pro Fit Ergo Wireless Keyboard is such that the wrists are supported in a fairly neutral alignment when the elbows are about 1" below the desk surface. For those who would rather sit at a more ergonomic height (i.e. elbows at or just above desk height) and benefit from a slight improvement in wrist alignment there are legs built into the underside of the palm support. When deployed these elevate the front to create a nominal 4° negative slope. When the keyboard is flat the highest point on the keys is 1.4" and with the negative elevation legs deployed the highest point is 1.9".

The island-style keys are fairly quiet but it should be noted that they have a moderately high peak operation force of 55 grams, which over time can cause fatigue and strain on the fingers. As well, the inner columns of keys are wider to create a more appealing look but this can lead to inadvertently striking the keys off-centre. When struck to the edge there is a tendency for these keys to partially bind, thus requiring more force to complete the key activation. This could lead to dropped keystrokes and an overcompensation response of exerting a higher degree of force to ensure activation. With a limited travel distance of just 2.5mm this will likely lead to the fingers impacting at the end of each keystroke.

The Pro Fit Ergo Wireless Keyboard is able to connect either via Bluetooth 4.0LE or the included 2.4GHz wireless receiver (replaceable if lost) which employs 128-bit AES government-grade encryption for security. The connection is switchable via a switch on the underside that also serves as a power switch.

Le Kensington Pro Fit Ergo Wireless Keyboard est en forme d'aile (winglike design) qui oriente les touches alphanumériques à environ 11°, les touches de navigation et du pavé numérique étant à 0°. Cette inclinaison des touches réduit la pronation des mains et des avant-bras pendant la dactylo. Les groupes de touches gauche et droite sont également ébrasés vers l'extérieur à 33° pour favoriser un alignement plus neutre et réduire la déviation ulnaire au niveau des poignets. Le support de paume intégré sur le Pro Fit Wireless Keyboard mesure un peu plus de 3po de profondeur et offre un rembourrage pour les paumes. Il est recouvert d'un matériau en similicuir facile à nettoyer.

L'angle et la hauteur du Pro Fit Wireless Keyboard sont tels que les poignets sont soutenus dans un alignement relativement neutre lorsque les coudes se trouvent à environ 1po sous la surface du bureau. Pour ceux qui préfèrent s'asseoir à une hauteur plus ergonomique (c'est-à-dire les coudes à la hauteur du bureau ou juste au-dessus) et bénéficier d'une légère amélioration de l'alignement des poignets, il y a des pieds qui sont intégrés sous le support de paume. Lorsqu'ils sont déployés, ils élèvent l'avant pour créer une pente négative nominale de 4°. Lorsque le clavier est à plat, le point le plus haut des touches est à 1.4po et lorsque les pieds d'élévation négative sont déployés, le point le plus haut est à 1.9po.

Les touches de style "island" sont assez silencieuses, mais il devrait être noter qu'elles ont une force de frappe significativement élevée de 55 grammes, ce qui, après un bout de temps, peut causer de la fatigue et des tensions sur les doigts. Également, les colonnes intérieures des touches sont plus larges pour créer un apparance plus intéressant, mais cela peut causer de frapper les touches sur le côté par accident au lieu du centre des touches. Lorsque les touches sont frappées sur le côté, elles ont tendance à se coller partiellement, ce qui nécessite une plus grande force pour compléter l'activation de la touche. Cela peut causer les caractères d'être perdus et une réponse excessive qui nécessite plus de force pour assurer l'activation de la touche. Avec une distance de déplacement limitée à 2.5mm, les doigts risquent d'avoir la vibration/choc de l'impact à la fin de chaque frappe.

Le Pro Fit Ergo Wireless Keyboard peut se connecter soit par Bluetooth 4.0LE ou par un clé USB 2,4 GHz inclus (remplaçable si perdu) qui utilise un cryptage AES 128 bits de niveau gouvernemental pour la sécurité. La connexion peut être facilement changer grâce à un bouton situé sous le clavier, qui sert également au bouton Connect/Off.

The Wireless Ergonomic Mini Trackball Keyboard from Adesso has a tenkeyless layout and features a fixed split design with integrated cursor control and clicking. The compact width of just 13.8" and incorporated cursor control reduce the risk of overreach not uncommon with full-width keyboards. This keyboard employs moderate resistance tactile membrane keyswitches to provide feedback while typing and the centrally-positioned 0.875" diameter trackball provides smooth and accurate cursor control while eliminating the need for extended reach to the mouse on the right or left. Vertical scrolling is provided by a scroll wheel positioned just above the trackball and between the left and right space bars. 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. 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 angle 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 Wireless Ergonomic Mini Trackball Keyboard includes an integrated sloping palm support. Composed of hard plastic that is fairly slippery, this can result in the hands slipping back off the keyboard. The shallow depth of the supports will most likely exacerbate this, so only those with the smallest of hands will actually be able to benefit from the proffered support. Both left and right Space Bar keys lack stabilization which leads to a variance in activation feel over the width of the spacebar.

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.

This keyboard is identical to the SK595 except that it is wireless (using an infrared line of sight method of transmission).
