The M570 Wireless Trackball takes most of the repetitive movements and strain which the entire hand usually must perform and allocates all the workload to the thumb of the user. Accurate optical tracking is provided by a 570 DPI laser sensor housed below the ball. With a contoured body that provides a relaxing support for the hand, the M570 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.

Connection is via a storable USB mini receiver and a single AA battery can provide up to 18 months of service. A battery life indicator will advise when the battery needs replacing. Software available from Logitech enables users to customize their trackball functions and performance.

Note: As the M570 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.

IOGEAR's Phaser 3-in-1 Presenter / Mouse is an excellent tool for presentations at offices, libraries, and schools. The thumb-operated multi-directional trackball allows the unit to work as a fully functional mouse, as well as a remote presenter. The built-in laser pointer helps the user to direct the audience's attention appropriately. The batteries can be easily charged through the USB charging cradle. The versatile Phaser 3-1 can also transform to a desktop mouse. The contoured design allows for comfort and less fatigue while in use.

The Pro Fit Medium Size Mouse from Kensington is a contoured, medium-sized, right-handed mouse that requires no drivers (works plug-and-play), is native USB with PS/2 adapter, and is durable (safe for drops and spills) for long-lasting comfort. Wired and wireless models are available.

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 Microsoft Arc Touch Mouse from Microsoft is an excellent choice for mobile mousing; its flexible design curves for comfort and flattens to pack. When curved, the mouse turns on, and when flattened, the mouse turns off (no button required). To scroll simply touch the scroll pad or flick it for fast vertical scrolling. The BlueTrack technology ensures accurate tracking on virtually all surfaces and the convenient 2.4 GHz Nano-Receiver can stow magnetically on back of mouse. For left-handed or right-handed users.

La Microsoft Arc Touch Mouse par Microsoft est une un choix excellent pour faire la souris dans les applications mobile; la conceptions est flexible car elle peut être courbée pour le confort, aussi que mis plat pour la ranger. Quand qu'elle est courbée, la souris est activée, et quand qu'elle est mis plat, elle est désactivée (pas de bouton bessoin). Pour faire le défilement, simplement touch le pad de défilement.

The Microsoft Wireless Mobile Mouse 4000 is a compact and portable wireless mouse using Microsoft's BlueTrack Technology. With a wireless range of up to 30 feet, the Mobile Mouse 4000 has a plug-and-go Nano transceiver for easy storage, reliable 2.4 GHz transmission for almost no interference, Flip 3D in Windows 7 to dynamically open windows with a single click, and a 10-month battery life.

Created for those wanting an ambidextrous, wireless mouse with a more traditional look, this mouse offers a symmetrical design and a centrally located scroll wheel. Thumb indentations on both sides of the mouse provide a textured anti-slip surface. The mouse gives left- and right-handed individuals the option of distributing the workload by using the same mouse in either hand.

The Goldtouch Wireless Ambidextrous Mouse has a 1000 dpi optical sensor, and is powered by one or two AA batteries. (Note: Estimated battery life is two months with one battery, and four months with two batteries.) A wireless USB 2.4 Ghz mini receiver is included.

Caution: Those with larger hands may find this mouse too small for all but occasional use.

The Sculpt Ergonomic Mouse from Microsoft is intended to encourage more natural hand and wrist postures with an angled body designed to remove the wrist from contact with the mousing surface. The sculpted thumb scoop helps the hand maintain this angled position which is intended to reduce pressure on the carpal tunnel. Windows 8 users can benefit from the clearly marked Windows Logo key which provides quick access to the Start Screen. The scroll wheel provides full 4-way scroll control and a convenient Back button is available for quicker navigation. While somewhat similar in design to the discontinued Natural Wireless Laser Mouse 6000, it should be noted that this mouse is smaller in all dimensions than the 6000. While making it easier to transport, by definition it provides less support for most individuals who do not have relatively small hands.

One limitation of this mouse is that it is designed to work only with recent versions of Windows (7, RT, & 8). and a driver download is necessary to take advantage of all the features.

The MX Vertical Advanced Ergonomic Mouse from Logitech is their first attempt at offering a mouse which more aggressively reduces pronation than other mice in their line. The body of the MX Vertical is angled at a fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide the support necessary for the hand to "relax" while engaged with the mouse. However, those with smaller or narrower hands may find that they need to maintain a degree of tension to hold their hands "up" in position over the buttons. Large or wide hands will likely have less of a problem with this requirement to maintain hand position.

The MX Vertical is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. Two nominal settings of 1000 and 1600 DPI can be adjusted anywhere within the range in 50 DPI increments. The top-mounted DPI button enables users to adjust the mouse as needed for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents. There are 4 programmable buttons (left, right, back, & forward).

The MX Vertical offers 3 connection options: Wired via the charging cord, 2.4Ghz Logitech Unifying Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). The 270mAh Li-Po rechargeable battery can provide up to 4 months use on a single charge and offers a 1 minute Quick Charge that can provide up to 3 hours of use. Of course, individual usage may affect this. Using Logitech "FLOW" users are able to connect to and control up to 3 computing devices using a single mouse.

The "flatness" of the buttons on the MX Vertical prohibit the fingers from achieving a fully relaxed and naturally curved "position of function". This factor, combined with the almost slick surface on the buttons could lead users to try to "pinch" the mouse between the thumb and fingers in an attempt to achieve a better sensation of "control". In addition, to minimize the activation force on the buttons the fingertips need to be as close to the end of the buttons as possible. Those with large hands or very long fingers may be able to achieve this position but most users will find their fingertips falling short of this "optimum" position, resulting in a higher force being required for click activation.

The RollerMouse Red by Contour Design is a central pointing device that is positioned in prime real estate immediately between the operator and keyboard space bar. This keeps all mousing activity "inline", i.e., in the area immediately in front of the keyboard, 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 RollerMice, 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). Eight buttons and a scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste, back, forward and vertical scrolling. There is also a cursor speed button between the copy and paste buttons for accessing ten different speed settings ranging from 600 to 2800 dpi. The Red also comes with adjustable keyboard "risers" to lift up standard and compact single piece keyboards. Controls can also be customized using the downloadable driver.

The RollerMouse Red is equipped with a larger diameter rollerbar than the FREE3 or PRO3. This 0.8" diameter bar is 7.1" wide and offers a finer degree of control, especially for vertical movement. The entire surface of the bar is textured with raised bumps that offer tactile feedback to further improve all aspects of cursor control. The robust aluminum housing is solid and sturdy, and the padded palm support can be removed if desired to reduce the overall depth for greater comfort or if space is constrained. Innovative tracking technology on the RollerMouse Red further enhances cursor control, especially valuable on multi-monitor workstations. All these design elements make cursor control more precise and effortless without compromising durability and robustness. 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.

The RollerMouse Red Wireless is available with two different depths of palm support. The standard model is suited for most individuals whereas the PLUS model has a noticeably deeper palm support that extends the overall depth of the PLUS by an additional 2.3 inches. Because this extra depth moves the Rollerbar and the keyboard further away from the body the PLUS is really only suitable for those with significantly larger or longer hands. Both models of the RollerMouse Red Wireless can also be purchased bundled with the low profile Balance Keyboard from Contour Design.

The RollerMouse Red is also available as a wired device. The RollerMouse Red offers all of the same features along with a direct, wired connection.

La RollerMouse Red Wireless par Contour Design est un dispositif de pointage central qui va immédiatement entre l`utilisateur et le clavier sous la barre d'espace. Toute l'activité de la souris reste ainsi "en ligne", c'est-à-dire dans la zone située immédiatement devant le clavier, ce qui évite de s`étirer pour chercher la souris. Cela permet également de l'utiliser dans les endroits où l'espace est insuffisant pour placer une souris juste à côté du clavier. Comme tous les RollerMice, l'utilisateur déplace le curseur en faisant glisser une barre de contrôle cylindrique avec le bout des doigts pour déplacer le curseur "haut" et "bas" et en faisant glisser cette barre d'un côté à l'autre pour un mouvement horizontal. Une fois l'emplacement souhaité atteint, l'utilisateur peut générer un clic gauche en appuyant sur la barre (la force nécessaire pour cela est réglable de ultra-légère à très tactile). Huit boutons et une roulette de défilement sont situés sous la barre pour générer des clics gauche / milieu / droit, copier, coller, reculer, avancer et défiler verticalement. Il y a également un bouton de vitesse du curseur entre les boutons copier et coller pour cinq réglages de vitesse différents de 800 à 2400 dpi. Le Red est également livré avec des "risers" ajustablent pour soulever les claviers conventionnels (d`un morceau et non pas pour les claviers séparer ou ajustable). Les commandes peuvent également être personnalisées à l'aide du pilote téléchargeable.

La RollerMouse Red Wireless est équipée d'une barre de roulement de plus grand diamètre que la FREE3 ou la PRO3. Cette barre de 0.8po de diamètre est de 7.1po large et offre un degré de contrôle plus fin, en particulier pour les mouvements verticaux. La surface entière de la barre est texturée avec des bosses élever qui offrent un retour tactile pour améliorer encore tous les aspects du contrôle du curseur. Le boîtier en aluminium robuste est solide et résistant, et le support de paume rembourré peut être enlever si vous le souhaitez pour réduire la profondeur totale pour un meilleur confort ou si l'espace est restreint. La technologie de suivi innovante de la RollerMouse Red améliore encore le contrôle du curseur, ce qui est particulièrement utile sur les postes de travail multi-moniteurs. Tous ces éléments de conception rendent le contrôle du curseur plus précis et sans effort sans compromettre la durabilité et la robustesse. Pour améliorer encore l'ergonomie, même le "clic" mécanique traditionnel a été remplacé par un mécanisme de clic "virtuel" plus récent qui génère un "clic" sans percussion mais audible, dont le volume peut être ajusté ou entièrement désactivé si on le souhaite.

La RollerMouse Red Wireless est disponible avec deux profondeurs différentes de support de la paume. Le modèle standard convient à la plupart des personnes, tandis que le modèle PLUS possède un support de paume significativement plus profond qui augmente la profondeur totale du PLUS de 2.3 pouces supplémentaires. Comme cette profondeur supplémentaire éloigne la Rollerbar et le clavier du corps, le modèle PLUS ne convient vraiment qu'aux personnes ayant des mains beaucoup plus grandes ou plus longues. Les deux modèles de la RollerMouse Red Wireless peuvent également être achetés avec le Balance Keyboard à profile bas de Contour Design.

La RollerMouse Red est aussi disponible avec fil. La RollerMouse Red offre toutes les mêmes fonctions tout en avoir la connection direct avec fil.
