The BIGtrack has a 3 inch trackball. The large ball requires less fine motor control than a standard trackball and it is ruggedly built. It has a left and a right mouse click button located behind the trackball to avoid unwanted mouse clicks. The large yellow trackball helps to make mouse movements easy and accurate. The oversized buttons make mouse clicks simple for those with poor motor control. The BIGtrack is switch adapted and comes with two standard 1/8" plugs for two switches. Its left and right mouse clicks have been adapted so that you can use a switch for activation. Alternate access. Appropriate for Early Access through adult. | |
