n-ABLER Trackball

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.

• Ergonomic Design: Pretorian products are designed with the user in mind, providing appropriate button positioning, ease of control and necessary hand support for all-round ergonomic benefit.
• Rugged Construction: Pretorian products are designed with the expectation that they may be subjected to less than ideal conditions. As a result their construction is intended to accept this type of usage without failure.
• High Visibility Controls: The n-ABLER Trackball features brightly coloured high-contrast buttons and trackball which act as visual aids to assist users who have vision or comprehension difficulties.
• Large Footprint for Maximum Stability: All Pretorian products are designed to ensure stability. The large footprint housing ensures that the devices are not easily knocked off of the surface on which they are situated.
• Standard Mounting Pattern: A standard 3-point threaded mount is provided on the underside for securing to any mounting surface.
• Symmetrical Design: The housing of the n-ABLER Trackball provides users with the freedom to easily switch between right or left use. Left and Right click buttons can easily be switched without the need of changing computer settings.
• Integrated Wrist Support: The Trackball offers a large surface on which to rest the heel of the hand. This means that the wrist can be maintained in a neutral position, reducing the risk of wrist extension and also permitting users to relax and allow the wrist to rest.
• Large Trackball: The large 63 mm, free-running ball ensures that cursor control requires nominal effort. Although the ball has significant mass it will still move with a minimal amount force. A speed control setting enables users to cycle through 4 levels of performance, choosing the one which best meets their needs at any time.
• Clearly Identifiable Controls: The large buttons on the n-ABLER Trackball feature primary colours with white legends in order to meet the needs of a wide range of users, including those who may have limited vision and may not be able to discern the legending.
• Assisted Access Buttons: All buttons recessed into the housing to prevent accidental activation. This positioning also serves as an aid to guide fingers directly to the buttons. This feature, combined with the wide positioning between buttons, greatly reduces the potential for accidental activation.
• Left to Right Switchable: On board programming lets users exchange Left and Right Click functions with no need to access or modify operating system settings.
• Re-Orienting Function: Not all users may find the traditional placement of the trackball to meet their needs. For this reason the n-ABLER can be 'taught' to orient itself to any 90° orientation. This function is performed 'onboard' with no need for driver support.
• External Switch Support: Two 1/8" mini phono plug sockets provide for the attachment of external left and right click buttons for users who may have trouble targeting the inset buttons. Check out our selection of switches that can be used with the n-ABLER Trackball.
• Double Click and Latching Drag Lock: Accomplishing a double-click action is nearly impossible for users with any kind of motor skills limitation. Being able to perform this with a single click is of major benefit for these users. For the same reason, holding down a button for dragging while moving the cursor is just as frustrating. The Drag Lock latches on to a selection until the button is activated a second time to release the latch. This releases the user to focus on the necessary cursor movement, be it selecting text or simply moving something on the screen.
• Axis-Lock Control: The Axis Lock button locks cursor movement to either the vertical or horizontal axis when activated. This can be of great benefit to those who experience involuntary muscle spasms or tremors which make fine cursor control difficult.
• Audible and Visual Indicators: A mutable buzzer apprises of a selection change when moving between functions and a multi-coloured LED serves to notify of the currently active mode.
• Cursor Speed Control: The n-ABLER Trackball is equipped with a cursor speed control switch that permits users to cycle through 4 cursor speed settings. This lets them select the speed which best serves their needs and is changeable at any time.
• PS/2 and USB 'Plug and Play' Installation: Installation is a breeze. Simply connect the USB and the trackball will automatically install. If a PS/2 connection is required just attach the adapter, plug it in and start/restart the computer.
• Wired Reliability: The Pretorian n-ABLER Trackball employs a wired USB connection which eliminates the potential for wireless to 'drop out' at a crucial moment. It also ensures the fastest communication - eliminating any potential for lag from wireless.

• If you are new to a trackball expect that it will take a while to get accustomed to the different style of control. It is also a good idea to limit the amount of time you use it in the first while. Rather, build up to longer periods of usage by interchanging with a different mousing device or by Load Balancing (see next point).
• Load Balance Your Use: The freedom of an ambidextrous trackball lets you easily switch between left and right handed use. Make a point of using it with your non-dominant hand. Not only is this good for your dominant hand, which gets a break from working, it can slowly build dexterity and endurance which your non-dominant hand generally does not have. As a bonus, it is also a way of stimulating the other half of your brain, which is never a bad idea. The n-ABLER trackball permits 'onboard' switching of Left and Right button functions to better accommodate load balancing.
• Take Regular Breaks: If you find that you are experiencing discomfort in your fingers, especially in the learning stages - that is a good sign that you may want to take a break by switching to a different device or by swapping to the other hand. As with any device, make an effort to regularly change your usage, take breaks, and perform stretches. Some users find that the fingers can benefit from occasionally flexing them through a full range of movement, both extending and contracting them fully.
• Remember to employ the one-touch Double Click, Drag-Lock and Axis Lock buttons to best benefit from the features available on your n-ABLER Trackball.
• If you experience tremors or muscle spasms consider using the Axis-Lock button to better control the cursor.
