The Communication Switch is designed for speech pathologists to monitor the progress of physically and mentally disabled individuals who have impaired verbal communication abilities. This communication switch consists of two modules -Simple Communication Switch (SCS) and Communication Switch Downloader (CSD).The SCS emits a light and tone to signal staff, counts the number of communications emitted and stores these data along with a device ID. The CSD connects to one or more SCSs to provide data collection, simple menu-driven LCD displq, SCS initialization and data transfer to computer.
