The Kensington Orbit Wireless Trackball with Scroll Ring is a stationary pointing device that replaces mouse movement with fingertip control of a 40 millimeter ball, suiting designers, editors and analysts working at crowded desks or on ergonomic keyboard trays. Because the base stays planted, the wrist and forearm remain still while the fingers do the work, which appeals to users managing repetitive strain and to anyone with limited desk clearance. A scroll ring encircles the ball for one-handed vertical navigation through long documents, timelines, code files and web pages, a smoother motion than a notched wheel across page-length travel. Optical tracking reads the ball rather than the desk surface, and pointer resolution steps through 400, 800, 1200 and 1600 dpi so cursor speed can be matched to spreadsheet detail work or wide multi-monitor sweeps. Dual wireless connectivity offers both a 2.4 GHz receiver link and Bluetooth Low Energy, and traffic is protected with 128-bit AES encryption for corporate environments that enforce wireless policy requirements. The ambidextrous layout serves left and right handed users equally, and a detachable wrist rest attaches at the front edge for added support during long sessions. Free KensingtonWorks software assigns functions to the programmable buttons, saving shortcuts for applications such as photo editors and browsers. Finished in space gray, the trackball works with Windows and macOS computers and installs with no drivers required.

The Kensington Orbit Trackball with Scroll Ring is a wired stationary pointing device for desk users who want to move the cursor from one spot instead of sweeping a mouse across a pad. A 40 mm space gray ball sits at the center of the housing and is driven with the fingertips, so the wrist and forearm stay still and no clear tracking surface is needed beside the keyboard. Wrapped around the ball is the scroll ring, a rotating collar that scrolls long documents, spreadsheets, and web pages in either direction with one finger and offers smoother, more gradual control than a stepped wheel. Two buttons flank the ball, and both can be reassigned through the free KensingtonWorks utility so frequent commands sit under the fingers already resting on the device. The shell is symmetrical, giving left and right hand users identical reach to the ball and the same button geometry, and a detachable wrist rest clips to the front edge to lift and cushion the heel of the hand for longer sessions. Optical tracking handles cursor movement without a mechanical roller, and the ball lifts free for periodic cleaning. Connection is plug and play over USB-A with no driver download, and the assembly measures 8.7 by 6 by 1.8 inches or 221 by 152.4 by 45.7 mm with the wrist rest attached. Because the housing stays in one place, the trackball suits narrow desks, height-adjustable desks, and shared benches where there is no clear room to sweep a mouse. Windows, macOS, and Chrome OS are supported, and the trackball is backed by a 5-year limited warranty.
