|---|
The Orbit Fusion Wireless Trackball from Kensington features a contoured body that supports the hand in a naturally relaxed position, rotated outwards at approximately 40°. The large 40 mm trackball provides silky-smooth and virtually effortless cursor control and is positioned so that multiple fingers can share the workload. Three DPI settings are available, a fixed 400 DPI for fine control and two dynamic ranges of 400-800 and 800-1500 DPI that respond to the rate of the trackball rotation to provide both speed and control. Speed adjustment is achieved via the thumb switch. A convenient patented light-action detent-free scroll ring around the base of the trackball gives quick access to scrolling and for viewing lengthy documents a quick press of the thumb on the middle-click button converts the trackball to scroll function. On the thumb side are conveniently-placed Left Click, Middle Click, Back and Forward, and DPI buttons. A large right-click button is positioned to the right of the trackball for access by the ring finger.
Since the Orbit Fusion connects wirelessly and can be placed on any surface - even soft or uneven ones, this a great mousing option when working on a Smart TV. The 2.4 GHz wireless receiver connects via USB-A or USB-C (using the included adapter) for laptops or devices that do not include full-size USB ports. Basic functions are available plug-and-play but can also be customized using the KensingtonWorks software (Windows and Mac)
Those who in the past may have used the Microsoft Explorer or Logitech TrackMan Marble FX trackballs may find the Orbit Fusion Wireless Trackball to offer a degree of similarity to these discontinued devices. The overall angle, hand placement and finger control are similar and are now combined with improved overall function and performance. | | Ergonomic Benefits |
|---|
Reduces Strain on Arm, Elbow and Shoulder Muscles - Because the Orbit Fusion Wireless Trackball does not need to move, the repetitive movements of the arm and shoulder associated with heavy mouse usage are greatly reduced. This in turn reduces the potential for injury and inflammation in these muscle groups. The housing of a trackball can also be angled in any direction, allowing each individual to position their elbow, wrist and hand in a straight line, and to limit ulnar and radial deviation. Learn More About Ulnar Deviation.
Reduces Strain on the Hand, Wrist and Arm - Trackballs effectively counter the tendency to grip the pointing device too hard, a grip that can cause pain and injury to the muscles and soft tissues in the back of the hand and in the wrist and forearm. As the trackball remains stationary, the Orbit Fusion Wireless Trackball lets the hand rest in a relaxed fashion, largely eliminating static grip. Learn More About Static Grip Force.
Ergonomic Support - The Orbit Fusion Wireless Trackball features a contoured shape that provides a natural, relaxing support for the hand.
Reduces Reach for Buttons - Left and right buttons are positioned for access by the same fingers used on a traditional mouse. The fingers are actually able to relax against the buttons, helping to avoid the development of Trigger Finger. Software to customize the button functions is available from Kensington. Learn more about Trigger Finger.
Can Be Used In Locations Where a Mouse Can’t - Because trackballs do not require a "mousing surface" in order to generate cursor control they can be used as easily on the arm of a couch as on the desk, or wherever else is found to be convenient and comfortable.
Effortless Cursor Control - The 40 mm trackball features a silky-smooth movement, responding to even the smallest of movements and minimizing the effort required to achieve fine cursor control.

- Convenient Back/Forward Control: Dual buttons enable easy movement forward and backward when surfing the Web.
- Dual Scrolling Options: Basic scrolling can be accomplished using the convenient detent-free Scroll Ring around the base of the trackball. For movement through lengthy documents a single "middle click" with the thumb will activate the autoscroll function, temporarily converting the trackball into an oversized scrolling "wheel".
- Multi-Digit Cursor Control: The trackball on the Orbit Fusion Wireless Trackball is positioned so that both the index and middle fingers have full access to the ball. This lets individuals spread their use across multiple fingers while also offering expanded control that single-digit trackballs are unable to provide.
- Wireless Convenience: The Orbit Fusion Wireless Trackball comes with a standard 2.4 GHz USB receiver and a USB-A to USB-C adapter to accommodate use on devices that do not have full-size USB ports.
- Precision Optical Tracking Technology: With an adjustable sensor that offers settings ranging from 400 - 1500 DPI, each individual can find a level of performance that will meet their work requirements. DPI settings are accessible via an easily activated thumb button.
- 40 mm Trackball: The 40 mm ball offers smooth and accurate cursor control, with minimal resistance.
- Easy Trackball Cleaning: Most trackballs will require occasional cleaning in order to ensure ongoing optimum performance. The ball on the Orbit Fusion Wireless Trackball is easily ejected from the underside of the unit.
- Natural Hand Support: The contoured body of the trackball is shaped to offer support for most hand sizes. Those with very large hands might wish to consider a device with a larger supporting surface.
- Battery Saving Switch: A simple On/Off switch on the underside of the trackball can be used to save battery power when it is be unused for extended periods.
- USB Receiver Storage: Lost or forgotten wireless receivers can be frustrating. Kensington has included a receiver storage slot in the underside of the trackball to keep the receiver with the trackball during transport. The USB-A to USB-C adapter does NOT have a storage slot.

| | Usage Tips |
|---|
- 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 intially limit the amount of time you use it. 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: Since the Orbit Fusion Wireless Trackball is a dedicated right hand mousing device it cannot be switched between hands. It is always a good idea to have an alternative device available, either for the other hand or one that lets your hand and fingers move differently.
- The Orbit Fusion Wireless Trackball facilitates cursor movement through multiple fingers. Rather than relying solely on either the index finger, which most people will tend to do, try to ensure that you use both fingers, spreading the workload across both fingers.
- Take regular breaks. If you find that you are experiencing discomfort, 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 find that the fingers can benefit from occasionally flexing them through a full range of movement, both extending and contracting them fully.
