Trackball Mouse



http://oldkeytools.bamroberts.com/mice/bigtrack_oversized_bright_large_trackball_for_kids.asp

Description of Technology: An adapted mouse with a zooming wheel and buttons.

Features:

  • Some available with sockets for ability switches (13)
  • The trackball can be used with another mouse (USB plug-in)
  • Designed for desktops and laptops
  • Takes up little room on desk
  • Colorful
  • Made to "sustain rough handling" (13)

Manufacturers: Logitech, BIGtrack, Microsoft, Kensington, Fellowes Micro Trac, IOGEAR Phaser, X-Arcade, Marble

Users/Benefits: Persons with lack of fine motor skills, carpal tunnel syndrome, or arthritis. "Just a touch from a knee, finger, elbow, toe or foot on the...ball is all it takes to cruise around the computer screen and a tap on one of the...buttons pulls out various other computer functions" (13).

Issues: Since trackballs, unlike a regular mouse, do not come with a computer purchase, they are an extra cost. Prices range from $13 (basic) - $100 (optical).
