Product Description
Maximum quantity available reached.

BIGtrack is a ruggedly built USB mouse that has a 3-inch trackball, oversized left and right mouse click buttons, and drag-lock feature. BIGtrack can be used with one or two switches. 

BIGtrack has a 3-in/7.6-cm trackball, which makes it the largest trackball mouse available. The large trackball requires less fine motor control than a standard trackball and it is ruggedly built. BIGtrack has a left and a right mouse click button located behind the trackball to avoid unwanted mouse clicks, and switches can be plugged into the two switch jacks to activate the left and right click function. BIGtrack also allows for second mouse connection; both BIGtrack and a second mouse can be connected allowing simultaneous participation.

Drag Lock

The drag lock feature enables a user to move objects on the screen without having to hold the mouse click button down. To activate the drag lock feature, position the mouse cursor over the item you would like to move. Once the cursor is positioned, double right click to lock onto the item. Once locked, the user can move the item with the trackball. Once a desired location is reached, activate either the right or left click button one time to release the object.

Switch Access

Plugging in a switch on the right side of BIGtrack 2.0 will enable the right click via the switch. Switch are not included and sold separate.

BIGtrack Manual



Issue 1: The BIGtrack is not installing correctly.

Possible Resolution:

BIGtrack uses a generic USB mouse driver that is typically already installed on most compatible systems. If you are experiencing an issue where the BIGtrack does not appear to function with your device after initial connection we recommend:

  • Try connecting BIGtrack to a different USB port on your device.
  • If using a USB hub, try plugging BIGtrack directly into your device.

Issue 2: A switch is not working when connected to BIGtrack.

Possible Resolution:

BIGtrack allows up to 2 switch connections for left and right click. If your switch is not working we recommend:

  • Connect the switch to a different switch port.
  • Connect a different switch, that you know works, to the same port.

Issue 3: BIGtrack is moving too fast/slow.

Possible Resolution:

BIGtrack is designed to use the mouse settings of your device. You will need to adjust the mouse settings to meet your needs.

Issue 4: The right button has a delayed reaction when activated..
Possible Resolution:

BIGtrack has two functions built into the blue button on the right that performs both right click (momentary press) and also a function called Drag Lock (press-and-hold).

The switch is used for two separate functions and has a slight delay in order to recognize which function it is to perform. This is normal.
