BIGtrack is the largest trackball around, giving people with fine motor control issues, small or large fingers easier access to the computer.
Controlling a mouse is essential for using a computer, and there should be more products out there like this to give people of varying dexterity equal access.
Some have used BIGtrack as a foot-driven input device, when using ones hands isn't an option.
Other features include a cursor trail function which, when enabled, lengthens the cursor trail making it easier to see on the computer screen for someone with a visual impairment. Both the BIGtrack and a second mouse can be connected together allowing for simultaneous participation between a student and his or her teacher.
The trackball is Windows or Macintosh compatible and comes with both a PS2 and USB connection.
