The n-ABLER PRO Trackball 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 involuntary 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 Trackball offers the same basic functions (cursor control, left click, right click, double click, and drag lock) as does the standard n-ABLER Trackball but in addition 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.

Cursor control is provided by a large 63 mm, free-running ball which responds to minimal effort. To avoid accidental movement the trackball projects only slightly above the housing, with the activation buttons fully recessed to avoid accidental activation as well as to aid users in button targeting. Dual mini-phono jacks 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 trackball also offers an optional buzzer setting which provides notification as specific functions are activated or deactivated.

The design of the n-ABLER PRO Trackball offers fingertip 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 Pro3 by Contour Design is a central pointing device that positions 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 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). The rollerbar mechanism is undergirded by a sturdy aluminum base that provides overall rigidity and keeps the RollerMouse from shifting position.

The cursor speed button located between the copy and paste buttons facilitates rapid selection between the ten cursor speed settings that range from 600 to 2400 dpi, ideal when work requires both fine control as well as rapid movement across multiple screens. Five buttons and a scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste and vertical scrolling. All button functions can also be customized using the downloadable driver. The Pro3 comes equipped with optional adjustable keyboard "risers" that can be installed to elevate low profile conventional and compact single piece keyboards. The body of the RollerMouse Pro3 serves as an integrated palm support, with padded leatherette cushions that can be detached for cleaning if necessary. If a larger and more cushioned palm support is desired the RollerWave3 Accessory can be purchased separately.

The RollerMouse Pro3 offers less access to the rollerbar, just 6.6", than either the RollerMouse Free3 or the RollerMouse Red. It also has a slightly shorter travel distance than either of those models. As a result, when working with multiple screens it will usually be necessary to employ a higher cursor speed setting. Doing this will help avoid activating the end detection that automatically moves the cursor to the far side of the screen. If regularly working across dual or triple monitors either the RollerMouse Free3 or RollerMouse Red models would be more suitable options as they both offer a greater range of cursor movement before the end detection function is activated.

La RollerMouse Pro3 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). Le mécanisme de la barre de roulement est soutenu par une base en aluminium robuste qui offre la rigidité générale et empêche la RollerMouse de se déplacer.

Le bouton de vitesse du curseur, situé entre les boutons copier et coller, facilite la sélection rapide entre les dix réglages de vitesse du curseur, qui vont de 600 à 2400 dpi, ce qui est idéal lorsque le travail exige à la fois un contrôle fin et un déplacement rapide sur plusieurs écrans. Cinq boutons et une molette de défilement sont situés sous la barre pour générer des clics gauche/milieu/droit, copier, coller et défilement vertical. Toutes les fonctions des boutons peuvent également être personnalisées à l'aide du pilote téléchargeable. La Pro3 est également livré avec des "risers" ajustablent pour soulever les claviers conventionnels et mince (d`un morceau et non pas pour les claviers séparer ou ajustable). Le boîtier de la RollerMouse Pro3 sert d'un support intégré pour les paumes, avec des coussins en similicuir rembourrés qui peuvent être détachés pour être nettoyés si nécessaire. Si désiré, un support pour les paumes qui est plus grand et mieux rembourré, l'accessoire RollerWave3 Accessory peut être acheté séparément.

La RollerMouse Pro3 offre moins d'accès à la barre cylindrique, seulement 6.6po, que la RollerMouse Free3 ou la RollerMouse Red. Sa distance de déplacement est également légèrement inférieure à celle de ces deux modèles. Par conséquent, en travaillant avec plusieurs écrans, il sera généralement nécessaire d'utiliser une vitesse du curseur plus élevé. Cela aidera à éviterer ainsi d'activer la détection de fin de course (end detection) qui déplace automatiquement le curseur vers l'autre côté de l'écran. Si l'utilisateur travaille régulièrement sur deux ou trois écrans, les modèles RollerMouse Free3 ou RollerMouse Red sont des options plus appropriées car ils offrent tous deux une plus grande gamme de mouvement du curseur avant que la fonction de détection de fin de course (end detection) ne soit activée.

The ProTouch from Sun-Flex is a central, multi-touch pointing device. The plug-and-play ProTouch positions directly in front of any standard straight-edged keyboard, moving cursor control and clicking actions to a central location easily accessed by either (or both) hands. The integrated touchpad allows individuals to move the cursor as they would with any other touchpad. However, the multitouch gesture technology also makes it possible to perform additional functions such as Left Click, Right Click, Scroll, and Zoom.

The ProTouch is solidly built with aluminum housing and tactile keys for quick access to common functions such as Copy, Paste, Left Click, Right Click, and Double Click.

The Orbitrack Control Ring from Pretorian provides users who have very limited range of movement or strength with a simple, almost effortless, means to perform cursor movement and click control.

The Orbitrack employs a touch-activated surface similar to a touchpad but without the necessity of continuous finger movement to 'steer' the cursor.Cursor direction is determined by where a finger is placed in relation to a central point in the touch ring. Once contact is made the cursor will begin slowly moving in the desired direction, gradually increasing the selected maximum rate of speed (4 selectable speed options are available). The cursor will continue to travel as long as the finger remains in contact - no further movement is required until a change of direction is desired. Direction change is accomplished by moving the finger to a new location on the control ring. This can be accomplished by breaking contact with the control ring surface and repositioning the finger to steer the cursor in the new direction or by sliding the finger to the new location. Users will vary in their ability to use the second option and may opt for the first method until they learn to better control the movement.

Requiring no hand or wrist movement, the Orbitrack represents a significant advance in computer input technology and is suitable for all computer users, particularly children and those with motor skill difficulties and movement impairment.

Note: The latest release of iOS13 for Apple portable devices includes 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 Mousetrapper Prime from Mousetrapper is an inline / central pointing device that offers the convenience and flexibility of both wired and wireless operation. As with all other members of the Mousetrapper family of devices, the Mousetrapper Prime facilitates cursor control through the innovative "steering pad". Incorporating features and concepts of both a touchpad and a treadmill, the steering pad offers fingertip control for precise cursor movement, left click activation and vertical scrolling. Eight programmable buttons, plus the steering pad, provide quick access to double click, left click, right click, zoom out, zoom in, cruise (or scroll) down, cruise (or scroll) up, copy, and paste functions. All buttons and cursor speeds are also fully reprogrammable if desired.

The Mousetrapper Prime sits directly below the keyboard with the steering pad centered below the alpha-numeric keys on a standard full-size keyboard and able to be controlled by either hand. The steering pad features a slip-free silicone traction surface for the finger tips, offering near-effortless onscreen navigation and cursor control. The fingers can rest on the steering pad between mouse activation tasks, with clicking accomplished simply by 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.

The Mousetrapper Prime features replaceable and wipeable palm supports and has an attached "keyboard support" that can be folded out to elevate low profile keyboards or folded below the Mousetrapper when using more traditional keyboards. Like most central pointing devices, the Mousetrapper Prime 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.

In addition to the above features, the functionality of the Prime is greatly enhanced by the downloadable MT Keys software, which includes the ability to paste text up to 254 characters long using a single button and to add user profiles. MT Keys can also be used to adjust the Mousetraapper Prime cursor speed (up to 2000 dpi). The wireless mode functions via USB with the included receiver, while the rechargeable battery has six months of battery life between charges.
