The n-ABLER Trackball from Pretorian is specifically designed to address the needs of computer users with limited hand control, motor skill difficulties, poor hand-eye coordination, and lack of manual dexterity. This functionality is packaged in a heavy duty housing designed to survive heavy use. High contrast coloured buttons and trackball assist users in determining position and function of the controls.

The n-ABLER Trackball 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 Trackball also offers a "Locking Axis" function which locks the cursor to either vertical or horizontal movement, addressing the difficulty of cursor control for users who experience tremors or may struggle with fine motor control.

Cursor control on the n-ABLER Trackball 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 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 trackball also offers an optional buzzer setting which provides notification as specific functions are activated or deactivated.

The design of the n-ABLER 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 Slimblade Wired Media Control Trackball from Kensington is designed to provide specialized functionality to those working with audio, video, or image editing. Three modes of operation can be accessed. The Slimblade defaults to View mode which offers traditional cursor control and scrolling function; however, Media and View modes can be easily accessed with a single click. The Media mode provides users with quick access to play/pause, stop, and track forward/backward functions while the View mode offers zoom and pan options. A heads-up display on the monitor advises users as to which application is active and what function is being performed.

The Slimblade departs from other Kensington trackball designs by employing a 55 mm trackball which is noticeably heavier for its dimensions than other models. In order to accommodate the need to grip and rotate the ball to accomplish common tasks such as vertical scrolling, 80% of the trackball projects above the housing height, resting freely on top of the trackball base.

Note: While providing users with a stylish look and generous functionality, the Slimblade Media Control Trackball does require repetitive pinching and twisting actions to perform common tasks. As well, the increased elevation of the trackball above the housing can lead to significantly greater wrist extension than other trackball designs. These types of actions and hand placement are often considered potential contributors to the development of complaints such as carpal tunnel or other RSI. Users may wish to consider the intended usage and the degree to which these actions may be required along with any realized benefits when selecting a suitable device.

The SimplyWorks Wireless Trackball from Pretorian combines the established technology and design of the Optima Trackball with the expanded capabilities provided by the SimplyWorks Wireless connection.The SimplyWorks Trackball employs optical sensor technology that eliminates mechanical parts which can fail from wear while still offering precise tracking and cursor control. Trackball movement is silky smooth and the stable low profile footprint makes the SimplyWorks Wireless Trackball suitable for a wide spectrum of computer users. The extended operating range (in excess of 10 metres) makes it ideal for use in multi-user settings and classrooms as it can be employed as a desktop or handheld trackball.

The SimplyWorks Wireless functionality means that this trackball can be combined with any combination of up to 5 other SimplyWorks equipped devices to communicate with a single computer through a SimplyWorks Wireless RECEIVE. This makes it an ideal solution for co-operative learning and interactive multi-user activities.

Colour-coded and recessed control buttons for Left Click, Right Click, and Drag-Lock are positioned above the trackball. The recessed location assists users in guiding their fingers to the appropriate buttons as well as preventing accidental activation that could occur with flush or raised buttons. In addition, the SimplyWorks Wireless Trackball is also equipped with dual ports which accommodate the attachment of external switches for activation of the left and right click functions. These can be used to offer users with limited motor control alternative methods of clicking.

Robustly manufactured, the SimplyWorks Wireless Trackball is virtually maintenance free (with the exception of battery replacement) and will give years of untroubled service.

* SimplyWorks is the world's first fully integrated wireless system designed specifically for users with motor skill difficulties.

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.
In the case of the SimplyWorks solutions, the Receive:2 is still required to support the pointing device connection. The Receive:2 plugs into the camera adapter cable and provides the wireless connection to the pointing device.

The L-Trac Switch Adapted from Clearly Superior Technologies features the high performance and robust build for which the original PC-Trac line is well-known. The L-Trac features an optical laser sensor which 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. The scroll wheel is smooth and readily accessible, located above the center button. Unique to the Switch Adapted version of the L-Trac is the availability of three jacks which support connection of external switches. Connecting an external switch deactivates the on-board switch for that function - a feature which can be of benefit when seeking to eliminate accidental button activation. This means that the click activations can be performed from alternate locations more advantageous to the user.

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 that 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 KidTrac trackball from Clearly Superior Technologies may be look like it is for children but users shouldn't be fooled by outward appearances. The bold bright colours—Yellow trackball with Red, Green and Blue buttons—is just a disguise for a highly functional trackball with capabilities suited to all ages.

Unlike most trackballs on the market, the high density 2.5" diameter phenolic trackball in the KidTrac has significant inertia. This provides far more tactile feedback than that normally offered with other trackballs, ensuring smooth response to even a light touch and requiring minimal dexterity of the fingers. Since the entire hand can be engaged in performing the trackball movements, the PC-Trac is a good solution for those who may have weakness or damage to the fingers, or for those who are seeking to avoid potential Repetitive Strain Injuries. Unlike some other trackballs, the trackball in the KidTrac is also safely secured in the housing to ensure that it cannot be easily removed, either by accident or deliberate action so missing trackballs or broken windows are not an issue.

The KidTrac 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.)
Since the low profile of the KidTrac housing acts as a natural hand rest, mirroring the natural contour of your hand, it can also reduce the risk of the wrist being inappropriately positioned and being injured as a result.The special 'Ambidextrous Trackball' feature allows switching from left to right-handed use by simultaneously pressing all 3 buttons, without the need to change system settings.

Users with vision limitations can especially benefit from the extra-large brightly coloured design which serves as an aid to clearly identify the button locations and functions. The light activation force and large dimensions of the buttons also mean that anyone with limited strength will be able to perform clicks as easily as any user. Users with motor function limitations may be interested in the Switch-Adapted version of the KidTrac which has three jacks for the connection of accessibility switches to provide easier access to the button functions.
