What it is

Summary

AI-generated from vendor-published content · October 1, 2026

The O-Trac is a USB trackball that moves the cursor when you roll a ball with your fingers or palm, so the hand can stay still instead of sliding a mouse around. The low, rounded case doubles as a hand rest, which can ease strain on the wrist. It has three buttons that work like a standard mouse, plus a drag lock: click once to hold a drag, click again to let go. That helps with selecting text or moving items without holding a button down. It works with Windows, Mac, and iPadOS/iOS, including iOS accessibility features like Switch Control, and it's sturdy enough for classroom use. It's a good fit for someone who finds a regular mouse hard to control, including children and adults.
