Some communication buttons and accessories are battery-powered (they use AAA batteries in various counts), while others are fully manual and require no batteries.
Recordable talking buttons are available for place words. For example, there’s a 3-button recordable "places" set that lets you record custom words and includes themed stickers.
An organizing mat is available in a two-piece design that holds up to six buttons, includes access holes for sound, and has puzzle-style connectors so multiple mats can be linked to build larger boards.
They support sound-based button communication, goal-tracking to monitor learning progress, and clicker-based mark-and-reward training that pairs the sound or button press with positive reinforcement.
Reported overall lengths range from 6 to 17 inches, widths from 1.2 to 12.8 inches, and weights from 0.1 to 4.5 pounds.
Different battery-powered models list different requirements — some require 2 AAA, others 6 AAA, and some 12 AAA batteries.
