9BUTTON Response Unit

The 9BUTTON was created by NwETA principals as a computer input device for people who are unfamiliar with computers and reluctant to touch a keyboard (“I might break it”). The 9BUTTON is constructed to sit above even the largest laptop keyboard or to replace a standard keyboard. It connects to a USB 2.0 port (backward compatible with usb 1.0) on the computer. The 9BUTTON offers a number of benefits:

  • Each button is backlighted to indicate when it is “active” and may be used for input. The buttons and their backlit states are mirrored by on-screen images that show what each button does when pressed.
  • The 9BUTTON has an external jack to operate a 12-volt device under program control. (For example a token dispenser or counter for correct responses could be plugged in here.)
  • Its 4th generation industrial design and manufacturing assure long life under rugged conditions. The lamps are LEDs that virtually never need replacement.
  • The 9BUTTON has received FCC and USB authority approval.
  • Your computer’s USB port delivers power to the circuit board and the LED lights in the buttons. There is no external power “brick”.
  • The button panel underside has a heavy gauge protective grille that allows ventilation while shielding the electronic components.
  • The 9BUTTON has been used extensively in testing with occupational populations, including those who have limited education (see Rohlman et al., 2003 and other Publications).
  • Unit dimensions: 39.5 cm x 28 cm (3.295 lbs)
  • Button dimensions: 1.5 cm x 2.0 cm

Note: Due to the interface methodology,
9BUTTON units can be used only with
cTRAIN and BARS software.
