The Ergo M575 Wireless Trackball from Logitech replaces the earlier M570 Wireless Trackball, offering improved connectivity options. Like its predecessor, the M575 takes most of the repetitive movements and strain which the entire hand usually must perform and allocates all the workload to the thumb. Accurate optical tracking is provided by a laser sensor that offers 400-2000 DPI resolutions. With a contoured body that provides a relaxing support for the hand, the Ergo M575 is equipped with a scroll wheel and right and left click buttons, all positioned as with a traditional mouse. In addition there are Back and Forward Buttons for convenience when browsing through multiple pages. The trackball body is shaped to let the hand rest in a natural relaxed position. As with the earlier M570 model, the M575 is best suited to those with small- or average-sized hands.

Connection can be made via either Bluetooth or the storable USB mini receiver, with a single AA battery providing up to 2 years of service. A battery life indicator will advise when the battery needs replacing. Software available from Logitech offers customization of trackball functions and performance.

Note: As the Ergo M575 places the workload fully upon the thumb, (which on most other trackballs is generally shared amongst several fingers), anyone who has existing thumb issues would be well-advised to consider alternative solutions.

The body of the Pro Fit Wireless Full-Size Mouse from Kensington is contoured for right-handed use and is large enough to provide support and comfort to larger hands. The driver-free Wireless mouse relies on the common 2.4GHz wireless technology (USB only) and works well in all office settings. The Pointer Speed Quick-Select button enables users to quickly switch between 800 and 1200 DPI settings and the back/forward thumb buttons enable rapid navigation within your web browser.

The RollerMouse Go (formerly the RollerMouse Mobile) by Contour Design is a compact version of the well-known RollerMouse Red, designed for mobility and ideally suited for use with compact keyboards. This central pointing device conveniently positions between the operator and keyboard space bar, keeping mousing activity "inline", i.e., in the area immediately in front of the keyboard, and eliminating the need to reach for a mouse. This also makes it suitable for use where there may be insufficient room for a mouse to be placed immediately beside the keyboard. Like all RollerMouse products, cursor movement is achieved by manipulating the tube-like cylindrical "rollerbar" with the fingertips. Rotating the rollerbar moves the cursor up and down, and sliding the bar from side to side accomplishes horizontal movement. Once the desired location is achieved, a left click can be generated by pressing down on the bar (the force required for this is adjustable from an ultra-light touch to highly tactile). Four tactile buttons and a clickable scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste, and vertical scrolling. Cursor speed can be adjusted via a button on the right end of the RollerMouse Go, with ten different speed settings from 600 to 4000 DPI. The RollerMouse Go also ships with two heights of rubber feet that can be used to elevate low profile compact keyboards to better match the rollerbar height. Controls can also be customized using the downloadable driver.

The RollerMouse Go is equipped with the same larger diameter rollerbar found on the RED, as compared to that on the FREE3 or PRO3. On the RollerMouse Go this 0.8" diameter bar is 3.875" wide and offers a finer degree of control, especially for vertical movement. The surface of the bar is textured with raised bumps that offer tactile feedback to further improve all aspects of cursor control. Innovative tracking technology on the RollerMouse Go further enhances cursor control, letting it work equally well on both single and multi-monitor workstations. All these design elements make cursor control more precise and effortless without compromising durability and the robust nature of the sturdy aluminum housing. To further improve the ergonomics even the traditional mechanical "click" has been replaced with a newer "virtual" clicking mechanism that generates a "percussion-free" but audible "click" that can be adjusted in volume or fully disabled if so desired.

Because the RollerMouse Go is designed for mobile use it offers features not available on the larger RollerMouse Red. This compact RollerMouse offers three connection options - to Bluetooth-enabled devices, via a an included 2.4 gHz wireless receiver, or as a wired device via the included charging cable. It also comes with a folding protective sleeve that attaches and closes magnetically.

The optional RollerMouse Go Dock accessory is for those who want the convenience of the more compact RollerMouse Go for travelling but desire the ergonomic benefits afforded by a full-size RollerMouse when they are in the office. The RollerMouse Go simply sockets into the Dock to provide extended palm and wrist support not only directly in front of the RollerMouse Go but also to the right, where a full-size keyboard will have the navigation and numeric keypad. And, when leaving the office, the RollerMouse Go again simply detaches from the dock for full portability.

While the RollerMouse Go and Dock can work perfectly well with any type or size of keyboard those using full-size or separated keyboards may wish to consider one of the full-size RollerMouse Models.

The Pro Fit Full Size Mouse from Kensington is a contoured mouse for right-handed users. This durable USB mouse requires no drivers and comes with a PS/2 adapter. DPI settings can be changed using the switch behind the scroll wheel. Wired and wireless models are available.

The Wireless USB-C Mouse from Matias is a compact ambidextrous mouse that will fit those with small hands and facilitate load-balancing to reduce RSI risk from using just one hand. Powered by a single AA battery (not included), the 2.4 gHz wireless connection is made through the world's smallest USB-C wireless nano receiver that protrudes just 1/8" from the USB-C port to which it is attached. The small size of the receiver lets it remain attached for immediate reconnection as soon as the mouse is turned back on. Two DPI settings of 1000 & 1600 can be adjusted from the underside where the power switch is also located.

This hard plastic mouse has a light surface texture that is comfortable to the touch and eliminates the need for the rubberized finish commonly applied to many input devices and which can become tacky over time.

All four switches (Left, Right, Scroll Wheel, and Control) offer a smooth activation with crisp tactile feedback and a quiet but audible click. The lightly-textured aluminum scroll wheel features soft but distinct detents. Just behind the scroll wheel is the control button that functions as a Back button in Windows and can be custom programmed in Mac environments.

The Wireless USB-C Mouse is available in both White and Black and is plug-and-play in both Windows and Mac environments. For convenience it can also share a single USB-C Wireless Nano Receiver with Matias USB-C 2.4 gHz keyboards, making it a convenient partner for data input.

The Pro Fit Ergo TB450 Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. The 45° angled body rotates the hand and forearm away from a prone position to reduce strain on the forearm. Cursor control is via the 34mm trackball which offers silky-smooth movement and adjustable optical tracking from 400-1600 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Vertical and horizontal scrolling function are provided by a tilting scroll wheel that features crisp detents, conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.

The Pro Fit Ergo TB450 Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth LE).

As the Pro Fit Ergo TB450 Trackball places cursor control fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be advised to consider alternative solutions.

The OrthoMouse from Orthovia is designed to put your hand in the 'position of function'. When you flex your fingers (i.e. curling your fingers into a ball) you are using the flexor muscles in your hand. When you open your hand (extending your fingers to a straight position) you are using your extensor muscles. The position of function is the point of balance between these two sets of muscles. This design also enhances the tactility of the mouse by using the extra sensitivity in your fingertips to provide maximum precision and accuracy.

The sensor is near the 'top' or tip of the mouse, directly below your fingertips, making the act of targeting and positioning the cursor a direct extension of your fingers (much like writing).

In order to accommodate the various hand sizes, the OrthoMouse comes with several slide-on attachments at the base and top of the mouse to accommodate different hand sizes and methods of use. This ensures an increased sense of tactility and confidence in cursor positioning, resulting in a very small learning curve. This mouse is ideally suited for anyone who is seeking a sense of precision and high tactile feedback including graphics designers and gamers.

Now available in Wireless (see detailed specifications for further details).
Note: Please note that the OrthoMouse replaces the traditional Scroll Wheel with thumb-operated buttons to create a 3-speed scrolling system. Please call for more details on this function.

La OrthoMouse par Orthovia est conçu pour mêtre votre main dans une 'position de fonction'. Lorsque vous fléchisez les doigts (courbé les doigts en rond comme une balle) vous utilisez les muscles fléchisseurs. Lorsque vous ouvrez la main (étendre les doigts jusqu'aux position droite), vous utilisez les muscles extenseurs. La position de fonction est le point de balance entre ces deux groupes de muscles. Ce design renforce aussi la tactiliter du souris en utilisant la sensibilité supplémentaire dans les bout de vos doigts pour permêtre la précision et d'exactitude maximum. Le capteur est proche du haut, ou au point, directement sous le bout des doigts, qui fait l'action cible et position du curseur une extension directe des doigts (beaucoup comme l'écréture).

Afin d'accommoder les tailles de mains variable, la OrthoMouse vient avec des diffèrents attachements qui ce connecte ensemble sur la base aussi qu'en haut du souris pour accommoder les différentes tailles de main aussi que les méthodes d'usage. Cela guarantie la tactiliter et confiance en la position du curseur, qui résulte dans une petite courbe d'apprendisage. Cette souris est, pour la plus part, idéal pour n'importe qui qui regarde pour une sense de précision et plus grande confirmation tactile qui inclu des créateurs graphique et les joueurs (gamers).

Maintenant disponible sans fil (voir les spécifications plus détailler pour plus d'information).

The Kensington Vertical Wireless Mouse angles the hand outwards towards a semi-vertical position in an effort to reduce pronation. A short flange keeps the side of the hand clear of the surface but still permits most of the little finger to make contact during movement. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. However, optional drivers are available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch accommodates quick access to five DPI settings (800, 1200, 1600, 2000, & 2400) to accommodate different work requirements. The wireless receiver has a 10 metre range and can be stored in the underside of the mouse to ensure it isn't misplaced. The traditional scroll wheel is clickable.

The size of this mouse means it is best suited for smaller or average sized hands. The body is narrower than most vertical mouse designs, which can lead to a tendency to want to "grip" the mouse which has the potential to lead to exerting unnecessary static grip force.
Note: While being identified by the manufacturer as a "vertical" mouse this angle is substantially less than most other "vertical" mousing products, the majority of which orient the hand well above 60° and therefore much closer to a truly vertical presentation.

The Handshoe Mouse from Hippus NV is designed to eliminate the 3 most common issues associated with the use of a computer mouse - gripping, pinching, and tensing of the fingers. The unique naturally supportive contours of the Handshoe Mouse permit the hand and fingers to completely relax whether actively engaged with the mouse or just resting between movements —like they do in a well-worn glove. This relaxed position eliminates the sustained static tension that most workers tend to maintain when using a mouse and which are associated with the development of RSI. The recommended usage for this mouse is on the desk surface with the forearm fully supported by the desk or arm rest of the chair.

Identical in physical design to the newest model of the Handshoe Mouse, the Original BlueRay Track model is now available at a significantly reduced price while supplies last. Wired and Wireless models are available in three different sizes for right hand only. If you are looking for a Left-hand version please consider the HandshoeMouse SHIFT (link below).

The Handshoe Mouse does not require any passive muscle tension to use, and prevents you from using any excessive muscle exertion while actively using the mouse, making it the only mouse on the market that is almost impossible to 'misuse'. Negative effects from 'anticipation of the click' (resulting in raised fingers and overexertion of the extensor muscles on traditional mice) are greatly reduced by the stabilized finger arch position provided by the design of the Handshoe Mouse. The design also incorporates a thumbrest which supports the thumb in a neutral and relaxed fashion, which also makes the Handshoe Mouse a good option for those experiencing thumb-related issues.

The optical tracking uses BlueRay Track technology and features a 1000 DPI sensor which will work on almost any surface. There are two buttons with scroll wheel (three on the large model) and a scroll wheel (clickable for middle click). No software is required - it works plug and play. It comes in black and is available in wired or wireless (the USB cable charges battery).

NOTE: For those seeking the best in performance and ergonomics, the HandshoeMouse SHIFT, which "SHIFTS" between Left- and Right-hand mode, is now available in three sizes. The HandshoeMouse SHIFT features greatly improved sensor sensitivity and Light Click Force Buttons which dramatically reduce the effort required to activate clicks.

NOTE: Due to the greater amount of weight resting on a Handshoe Mouse (larger mouse, weight of hand and part of forearm) it is recommended that a firm, low friction mousing surface be used to minimize the effort required to move it.

La souris Handshoe de Hippus NV est conçue pour éliminer les 3 problèmes les plus commun associés avec l'utilisation d'une souris d'ordinateur: le serrage, le pincement et la tension des doigts. Les contours uniques et naturels de la souris Handshoe permettent à la main et aux doigts de se détendre complètement (comme dans un gant usé), que ce soit avec la souris ou simplement entre deux mouvements. Cette position détendue élimine la tension statique soutenue que la plupart des utilisateurs ont tendance à maintenir lorsqu'ils utilisent une souris et qui sont associés au développement de RSI. Avec plusieurs options de taille disponibles: 4 pour la droite et 3 pour la gauche, toute personne peuvent avoir une solution pour la souris qui supporte au complete la main, le poignet et les doigts. L'utilisation recommandée pour cette souris est sur une surface de bureau avec l'avant-bras entièrement supporté par le bureau ou l'accoudoir de la chaise.

Identique à la conception physique du nouveau modèle de la souris Handshoe, le modèle Original BlueRay Track est maintenant disponible à un prix considérablement réduit jusqu'à épuisement des stocks. Les modèles avec fil et sans fil sont disponibles en trois tailles différentes pour la main droite uniquement.

La Handshoe Mouse n'utilise pas les muscles en tension passive, et empêche l`utilisateur d`utiliser des efforts excessifs des muscles pendant l`usage. Cela permet la souris Handshoe Mouse d`être la seule souris sur le marché qui est presque impossible de l'usage abusif. La courbe du forme waterfall de la souris Handshoe Mouse offre un courbe naturel pour les doigts, qui les permets de se détendre au complète entre les clics. Cela élimine les effets négatives de "l'anticipation du clic" que les souris traditionnels offrent, et en conséquence ont les doigts soulevés, survolés et la fatigue et l`extensions des muscles extenseurs. Ce concept offre aussi un appui pour le pouce qui support le pouce dans une position neutre et détendu, et en effet le Handshoe Mouse est une bonne option pour ceux/celles avec des douleurs relier au pouce comme le DeQuervain's Tenosynovitus.

Le capteur optique utilise une technologie bluetay track combiner avec un senseur de 1000 DPI qui va fonctioner sur presque tout les surfaces. Il-y-a deux boutons aussi qu'une roulette de défilement (trois boutons sur le modèl Large). Pas de logiciel requise--elle fonctionne plug and play. Elle vient en noir et est disponible avec fil ou sans fil (la corde USB charge la batterie.)

Veuillez Noter: Pour les gens qui veulent la meilleure performance, aussi que l'ergonomie, le modèlHandshoeMouse est aussi disponible qui vous donne une plus grande choix des tailles pour la main droite, aussi que gauche, et vient avec un senseur de 1500 DPI aussi que nouveaux boutons avec force plus léger réduit considérablement l'éffort pour générer un clic. Veuillez Noter: Due au montant élevé du poids reposé sur la souris Handshoe Mouse (avec la souris plus gros, le poids du main aussi que partie de l'avant-bras) il est recommendé qu'un tapis de souris qui est ferme, qui a une surface avec peut de friction soit utilisé pour diminuer l'éffort demander pour la bouger.
