PC-Trac

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 users, as well as different size hands.

Unlike most trackballs on the market, the high density phenolic trackball in the PC-Trac has significant inertia. This provides far more tactile feedback than that normally offered 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.)

PC-Trac basic models offer both "middle click" and "drag lock" functions (see the Features for more details.) On the Pro models this button only supports "middle click" but there is downloadable software available which enables users to customize their trackball features. There is also a 5-button model which offers 2 input jacks for the connection of optional external switches.

• Middle Button Hardwired for Drag-Lock (for non-Pro models): The Middle utton is a drag-lock - this means that there is no need to hold a button down to highlight, select or drag an item. This is a real plus for individuals with trigger finger, who are constantly having to click, or for those with motor skill difficulties.
• Middle Button in Scroll-Lock Mode: The middle button can also act as a scroll-lock. To have the button perform a scroll-lock (instead of the default drag-lock), press and hold the button for 2.5 seconds and it goes into scroll-lock mode. To leave scroll-lock mode, press any button again.
• Universal Compatibility: The universal compatibility of this design means it works well in a multi-user environments with a range of individuals.
• Low Profile: The low profile case of the PC-Trac case acts as a natural hand-rest, mirroring the natural contours of the hand.
• Robust Design: Employing strong ABS plastic construction, a virtually indestructible phenolic trackball and stainless steel rollers, Clearly Superior Trackballs are designed with durability a key consideration. .
• Dynamic Acceleration: The Dynamic Acceleration feature incorporated into all PC-Trac models is especially beneficial to users working with large high resolution screens or those who need to rapidly move the cursor across greater distances. This feature ties the distance travelled to the speed with which the ball is rotated. For example, a 1/4 rotation of the ball at a rapid rate will cause the cursor to cover a substantially greater distance than the same 1/4 rotation performed at a slow rate. This can be especially beneficial for uses (such as CAD) where exceptional accuracy is required at one moment while still needing to move larger distances the next. Users are able to set the resolution of the trackball to a lower setting in order to achieve a greater degree of control, yet with a rapid movement of the ball can still cover the greater distances necessary for accessing menus. A "fixed acceleration" trackball would require a greater degree or number of rotations in order to cover these larger movements, resulting in an increase in the amount of necessary finger movement.
• Software for Additional Functionality: PRO models of the PC-Track support Superior-X Button Control for Windows or USB Overdrive for Mac, enabling users to set different button settings depending on the application. This allows control of applications, such as media players, directly from the trackball (volume control via scroll wheel, etc.), putting maximum control at your fingertips. Superior-X also allows keystrokes to be recorded and played back with the click of a button, allowing repetitive application tasks to be completed quickly.
• Large Weighted Trackball: The large 57 mm ball provides increased accuracy and control. The weight also enables rapid movement across large distances as it can be "spun".
• Ambidextrous Design: The symmetrical, comfortable design means that both left and right-handed users will be able to enjoy the benefits of the Expert Mouse Wireless Trackball.
• Switch Adapted Model: The switch adapted model of this trackball is a two button device that has three 3.5 mm audio jacks positioned on the side of the trackball. These jacks are arranged in parallel to the buttons on the trackball, and you can plug in any standard switch to generate the 3 different button actions corresponding to the regular buttons (left click, drag lock, right click). There are a variety of Switches which can be used with the SA models of the lPC-Trac, Kid-Trac, or L-Trac trackballs.

• 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.
• 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.
• Employ the "Dynamic Acceleration" feature to reduce unnecessary repetitive rotation movements when needing to move across large distances. Moving the ball quickly will cause it to cover a much greater distance than it will if rotated slowly for the same amount of rotation (i.e. a quarter of a rotation at a higher speed will cover a much greater distance than a quarter of a rotation at a slow speed).
• If you have a PRO model consider installing the Superior-X Button Control.
  Note: Follow the manufacturer's instructions for removing other input device software prior to installing the Superior-X software.
