Ready to use The device is physically plug-and-play and requires no drivers, so basic cursor control is immediately available. However, getting full value — particularly on iOS with Switch Control or AssistiveTouch, or correctly configuring drag-lock for a specific user's motor profile — benefits from consulting accessibility settings documentation or an OT/ATP. This tips it above self-serve but doesn't require a professional for basic use.

What it is

Summary

AI-generated from vendor-published content · April 26, 2026

The X-keys O-Trac Trackball is a USB trackball designed as an accessible alternative to a standard mouse, using a rolling ball to move the cursor without requiring wrist movement or precise hand-dragging. It's a good fit for children or adults who have difficulty with the fine motor control needed to operate a conventional mouse — including those with limited grip strength, tremors, or coordination challenges. The device is plug-and-play over USB and includes a drag-lock feature that lets users lock a click-and-drag action without holding the button down, which removes a common barrier for people who can't sustain a button press. It's sized and styled for younger users, so adults with larger hands may find the form factor a bit small for long sessions.

What Setup Looks Like

  • Out of the box
    1. Plug the USB cable into any available USB port on a Windows PC, Mac, or iPad (with adapter).
    2. Move the trackball immediately — no software installation or drivers required.
  • With a guide
    1. On iOS/iPadOS, enable Switch Control or AssistiveTouch in Settings > Accessibility to take full advantage of the trackball's compatibility with Apple accessibility features.
    2. Review the drag-lock functionality in the product documentation to configure button behavior for your user's needs. (Estimate: 15–20 minutes. See manufacturer support resources for detailed instructions.)
