BIGTrack2 Trackball Mouse
The BIGtrack 2.0 is a wired alternative pointing device. This alternative pointer is a USB mouse that includes a large 3-in / 7.62-cm trackball. The base of BIGtrack 2.0 allows the user to move and position the mouse cursor on the computer screen while using fine or gross motor movements of the hand, arm, or foot. Once the mouse cursor is positioned, two over-sized buttons are available for left and right clicking. Individuals who have a dexterity limitation that limits their ability to move their entire arm to control the cursor may benefit from this device.
