The L-Trac from Clearly Superior Technologies combines a high level optical sensor capable of resolutions up to 1600 CPI (counts per inch) with the robust build for which the original PC-Trac line is well-known. The L-Trac features an optical laser sensor that offers "button selectable" tracking resolutions of 400, 800 and 1600 CPI, easily changed on the fly. Combined with this is the ability of the L-Trac to track at speeds exceeding 30 inches per second, even at a 20G acceleration rate. An optional scroll wheel (available on select models) is smooth and readily accessible, located above the center button.

The L-Trac provides users with a precision, high performance pointing device. The large 57 mm diameter weighted trackball produces predictable, quick, and precise cursor control. Most users will find that movement becomes intuitive within a few minutes of use, with the level of control increasing over time.

The level of performance and range of features, coupled with the proven contour of the L-Trac makes these trackballs an appropriate option for all applications including general computing, gaming and Computer Aided Design (CAD). CAD users love it because you can drag a line one pixel even on high resolution displays. Then, with a button stroke, they can fly around the screen to get general tasks done. Gamers have called it an "almost unfair advantage", citing the fingertip control and precision, high performance tracking.

Designed to minimize the effects of contamination build up and the resultant degradation of performance, this high performance laser trackball uses highly polished stainless steel rollers. It has been found by CST that the "ruby ball sliders" used in most optical trackballs, cause performance degradation when gunk builds up on them. The L-Trac uses mirror polished stainless steel rollers do not readily collect unwanted material and are easily cleared by spinning the ball rapidly. The Dupont Delrin bearings are embedded with Teflon and internally coated with a lifetime lubricant making the feel of this trackball extremely smooth and it's reliability very robust. The user-replaceable stainless steel rollers are extremely tough and designed to handle hard usage yet still provide users with controlled smooth movement.

The L-Trac is now available from PI Engineering as the X-Keys L-Trac

The n-ABLER PRO Joystick from Pretorian is specifically designed to address the needs of computer users with limited hand control, motor skill difficulties, poor hand-eye coordination, lack of manual dexterity, and muscle spasms. This functionality is packaged in a "Professional" housing that will blend easily into office or classroom environments, reducing undesired attention. The glossy silver upper housing offers limited resistance to hand repositioning and the black buttons feature contrasting white legends for increased visibility.

The n-ABLER PRO Joystick provides cursor control as well as single-click controls for left click, right click, double click, and drag lock functions. In addition the n-Abler PRO Joystick also offers a locking "pan" function which enables vertical and horizontal scrolling using the trackball without the need to hold down a button. It also features an "Anti-Tremor" function with three settings to enhance cursor control for users experiencing hand tremors of varying degrees.
Users who experience muscle spasms or extreme tremors may be interested in considering the n-ABLER Joystick or n-ABLER Trackball, both of which feature an "AXIS LOCK" which locks the cursor to the Vertical or Horizontal Access.

Cursor control on the n-ABLER PRO Joystick is provided by a joystick control which can be equipped for the individual needs of a user. Included are a standard joystick, a T-Bar handle, and a soft-grip ball. Dual mini-phono jacks also permit the attachment of a variety of external switches to provide users with easier access to the Left and Right click functions. Users who find the traditional orientation unsuitable have the option of "teaching" the trackball to orient itself at 90° increments, freeing the user to change the housing orientation for optimum usage and comfort. The n-ABLER Joystick also offers an optional buzzer setting which provides notification as specific functions are activated or deactivated.

The design of the n-ABLER PRO Joystick offers precision control and requires only minimal hand movement. This can reduce wrist and elbow fatigue, as it requires noticeably less effort. The symmetrical design enables users to work with either hand without having to angle the wrist, and the unit can also be configured for left-handed operation. Its large, integrated hand support/palm rest makes work posture more relaxed and less strained.

Note: The release of iOS13 for Apple portable devices included support for USB Pointing Devices. This means that virtually all of the Pretorian Mouse Replacement solutions can now be used with iPads and iPhones that have iOS13 or newer. Connection to the portable device requires a camera adapter cable. Because the mousing device will be powered by the phone or tablet it is preferable to use one with pass-through charging so the portable device can charge while the mousing device is attached and in use.

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 Mobile, with five different speed settings from 600 to 3000 DPI. The RollerMouse Mobile 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 Mobile is equipped with the same larger diameter rollerbar found on the RED, as compared to that on the FREE3 or PRO3. On the Mobile 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 Mobile further enhances cursor control, letting the Mobile 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 Mobile is designed for mobile use it offers features not available on the larger RollerMouse Red. The Mobile 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.

While the RollerMouse Mobile 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 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 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 is available with two different depths of palm support. The standard model is suitable 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 can also be purchased bundled with the low profile Balance Keyboard from Contour Design.

The RollerMouse Red is a wired device but if the freedom of a wireless device is desired the RollerMouse Red Wireless offers all of the same features combined with the convenience of wireless connection.

La RollerMouse Red 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 600 à 2800 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 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 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 peuvent également être achetés avec le Balance Keyboard à profile bas de Contour Design.

La RollerMouse Red est une souris avec fil, mais si vous souhaitez bénéficier de la liberté d'une souris sans fil, la RollerMouse Red Wireless offre toutes les mêmes fonctions combinée tout en être sans fil.

The Orbit Wireless Mobile Trackball from Kensington is a compact ambidextrous trackball mouse that provides the convenience of wireless in a small footprint. The compact size and wireless convenience make it a suitable solution for short-term mobile usage or for users with small hands who may find other trackball options to be a bit large.

The Orbit Wireless Mobile Trackball is plug and play (no driver required). Buttons situated on the outer sides of the trackball housing provide access to Left and Right Clicks. Scrolling is available via dual Touch Scroll Zones that are positioned to the left and right of the compact 32 mm trackball. Functions can also be customized by installing and running the TrackballWorks software from Kensington. TrackballWorks offers button customization as well as cursor and scrolling speed adjustment options.

In order to extend battery life the wireless range is limited to 10 feet. Users are notified of necessary battery replacement by a low battery indicator light. A power switch further reduces unnecessary battery consumption. In step with the mobile focus of this product, the micro receiver can be conveniently housed in the body of the mouse during travel or storage.

The Mousetrapper Advance 2.0 is an inline / central pointing device that is based around the innovative "steering control pad" that incorporates features and concepts of both a touchpad and a treadmill. The silicone-coated, slip-free steering pad requires only finger-tip pressure to achieve precise cursor movement (up to 2000 DPI), left click activation and vertical scrolling. Unlike traditional touch pads where the finger is moved across a static surface, the fingertips are used to dynamically move the steering pad, sliding it left or right and "running" it up and down in treadmill-like fashion. The fingers can rest on the steering pad between mouse activation tasks, with a left click being activated anywhere on the steering pad by simply pressing down against the pad. Because the fingers are physically moving the steering pad there is a much greater degree of tactile feedback than is provided by traditional touchpads, which in turn facilitates a greater degree of accuracy and control. As well, because the steering pad is not touch-sensitive there is no fear of movement disruption if additional fingers contact the steering pad - in fact, most people will naturally use multiple fingers to move the pad, making it a more natural movement than traditional touchpad control. The two-dimensional steering pad also offers an intuitive interface that for some may be easier to adjust to than rollerbars, touchpads or trackballs.

Six buttons adjacent to the steering pad provide quick access to double click, right click, left click, cruise (scroll)-up, and cruise (scroll)-down functions. All click functions can be re-programmed or customized using the optional MT Keys software which offers a wide range of keyboard short cut or macro options as well as cursor DPI adjustment. An integrated "keyboard support" pad can also be folded out to elevate low profile keyboards or stored below the Mousetrapper when using more traditional keyboards.

The body of the Mousetrapper Advance also serves as a palm support to help minimize the risk of wrist extension with replaceable Lycra-covered pads offering cushioning to reduce pressure points against the palms and wrists. Like most central pointing devices, the Mousetrapper Advance requires no overextension of the shoulder joint, and can significantly reduce the risk of repetitive strain injuries to the muscles of the shoulder and upper back.

The Advance 2.0 differs from the Advance (SMT417) cosmetically by being available in two models with stylish accent colours: white (MT112) or turquoise (MT113). Functional differences include six programmable buttons instead of five — the central button on the Advance has been replaced in the 2.0 with two scroll buttons for up and down. In addition, the palm supports on the Advance 2.0 are replaceable (unlike those on the Advance), which makes cleaning the palm supports much easier.

The Mousetrapper Advance 2.0 est un dispositif de pointage central qui utilise un mécanism de tapis roulant (un hybride entre un touchpad et treadmill) pour le mouvement du curseur aussi que les actions du clic gauche. Le pad pilotage est fabriqué avec une surface enduit de silicone, onduté, qui offre le control façile des doigts, et exige le dextérité minimal pour bouger le curseur. La surface du pad est effectivement un matiériel adhérence sur les doigts, qui façilite le mouvement du pad pilotage. Le control exige l'effort minimale car le pad bouge sans effort. Ce niveau de fonctionnalité peut être opposer des touchpads lorsqu`on glisse le doigt sur une surface static qui ne bouge pas.

Le pad pilotage sur l`Advance 2.0 offre le défilement à deux dimensions aussi que défilement vertical. Le clic gauche peut ce faire n'importe endroit sur le pad de pilotage. Les boutons autour du pad pilotage offre l`acces au double clic, clic gauche, clic droite, et les fonctions du clic de millieu. 

Le Mousetrapper Advance 2.0 a des supports de paume en lycra qui sont remplacable. Il y a aussi un tapis flexible en couleur gris qui est attacher pour mêtre un clavier dessus. Comme la plus part des dispositif de pointage centrals, le Mousetrapper Advance 2.0 empêche de s'étirer trop dans la jointure de l`épaule, et peut considérablement réduire les blessures dans les muscles du cou et le haut du dos.

L`Advance 2.0 est différent que l`Advance (SMT417)  cosmétiquement en étant disponible en deux modèles avec des couleurs vives: blanc (MT112) ou turquoise (MT113). Les différences fonctionnelles incluent six boutons programmables au lieu de cinq — le bouton central de l’Advance a été remplacé dans la version 2.0 par deux boutons de défilement pour le haut et le bas. De plus, les supports de paume de l`Advance 2.0 sont remplaçables (contrairement à ceux de l`Advance), ce qui facilite grandement le nettoyage des supports de paume.

The Easy Cat USB AG Touchpad from Cirque Corporation offers highly responsive and virtually effortless cursor control and click activation. The low profile also virtually eliminates the potential for wrist extension and the ambidextrous design accommodates use with either hand for those who wish to spread the load between hands. Cursor control is accomplished by lightly sliding the fingertip over the surface and requires no pressure. Cursor tracking with the Easy Cat is accurate and reliable - always following the "point of first contact", unlike other less-advanced touchpad devices that can have difficulty when a second contact is accidentally made. Generation of both left and right clicks is accomplished by lifting the finger clear of the touchpad and then lightly touching the surface to perform a click. Right clicks must be performed in a triangle in the upper right of the touchpad, identified by both colour and texture. Vertical scroll is supported via a vertical scroll area on the right edge. The AG (Advanced Gestures) model incorporates both single and multi-finger gestures providing quick access to Pinch Zoom, Scroll/Pan and other actions.

The Easy Cat AG offers both single and multi-finger gestures to provide quick access to standard functions of left and right clicking, zoom, scroll, pan and as well as other actions. The Easy Cat AG is also equipped with 2 mechanical buttons that by default perform standard left and right clicks but which can also be programmed to complete custom commands or functions.

Note: Multi-finger gestures and custom programming are only available with the Windows OS GlidePoint driver installed. Those operating Mac OS can access standard touchpad features of cursor control and clicking as plug-and-play functions.

Those looking for a larger touchsurface area, expanded functionality, and a broader range of touch-activated command options may be interested in considering the Smart Cat AG or Smart Cat Pro AG touchpads.

Le Easy Cat USB AG Touchpad de Cirque Corporation offre le contrôle du curseur aussi que l`activation de clique sans effort. Le suivi du curseur est accomplis par le mouvement lisse et doux du doigt, et n`exige pas de pression. Pour faire le clic gauche et droite, c`est accomplis par lever le doigt complètement de la surface et de re-toucher la surface pour faire le clic. C`est un dispositif très compact et durable aussi qu` économique. Le défilement vertical est fait dans un espace spécialisé à gauche. Le Easy CAT USB AG (Advanced Gestures) incorpore les gestes seul ou multi-doigts ce qui donne l`accès à Pinch Zoom, Scroll/Pan et autre actions.

Les utilisateurs qui veulent des fonctions supplémentaires ou une surface plus grande vont peut-être vouloir considérer le touchpad Smart Cat AG ou le Smart Cat Pro AG .

The X-Keys O-Trac from PI Engineering is a robustly built trackball with a long history of durability, reliability and performance, carrying on the legacy of the PC-Trac Trackballs formerly manufactured by Clearly Superior Technologies.

The X-Keys O-Trac Trackball offers a gently-angled profile that serves as a natural hand rest. The gradual curve of the body mirrors the natural contour of the hand and is designed to easily accommodate both right- and left-handed use, as well as multiple hand sizes.

Unlike most trackballs on the market, the high density phenolic trackball in the O-Trac has significant inertia. This provides far more tactile feedback than that normally offered by mass market trackballs, while still offering smooth response to even a light touch. The PC-Trac also offers "dynamic acceleration" which increases distance covered proportional to the speed of rotation. This feature ensures fine control as well as offering accurate rapid movement when required. (See the Features section on the Detailed Specifications Page for a deeper explanation of this feature.)

The O-Trac Trackball offers both "middle click" and "drag lock" functions (see the Features for more details

X-keys Trackballs work right out of the box, no software is required. If you wish to assign different functions to the buttons the manufacturer recommends using X-Mouse Button Control.

The PC-Trac from Clearly Superior Technologies is a robustly built trackball line offering options and features not readily available in other trackballs.The low profile of the PC-Trac acts as a natural hand rest mirroring the natural contour of your hand and is designed to easily accommodate both right and left-hand use, as well as different size hands.
