Program Language

Dataflow

O-1: (int) eegValue O-2: (float[][]) WebcamData O-3: (String) SQL SQL Example: CREATE TABLE `PLD` ( `ID` int(11) NOT NULL auto_increment, `TITLE` varchar(255) NOT NULL default '', `CACHE_TITLE` text, `TITLE_URL` varchar(255) default NULL, `CACHE_URL` text ) Dataflow between I/O Layer

O-4 to O-9: (Object) Event Handler Message Object Event handler message = { source: “”, sourceMethod: “”, destination: “”, destinationMethods: “”, data: void*, dataType: “” } O-10: (String) JSON JSON = (JavaScript Object Notation) JSON Example: Dataflow between Logic Layer

O-10: (String) JSON O-11: (String) Link Note: Most browsers will open a URL if provided as a parameter after browser call. Dataflow between Controls Layer
