EPICS for Kids presents Visual Communicator Abstract Many people exist in this world who are disabled and need help in order to overcome their mental and physical limitations. Although assistive technology exists to help such people, the devices in existence are too general and do not always address specific needs well enough to be helpful for certain people. Many times, the device must be customized to meet these special needs.
