The app interfaces to NeuroSky devices using the ThinkGear Socket protocol (connecting on localhost:13854), retrieves data in JSON Format, and can "stream" to other applications. Mindstream can save the following data: * Focus levels - attention - meditation * EEG values - delta - theta - lowAlpha - highAlpha - lowBeta - highBeta - lowGamma - highGamma * Headset signal strength - poorSignalLevel Streaming functions will include: * [Currently Implemented] Saving EEG data to a CSV File * [TBD] Listen on a socket and replay data from localhost:13854 - allowing other applications to connect * [TBD] Broadcast to a URL - supporting POST/M-POST and streaming real-time data - future use? Processing Javascript version of the Neurosky BrainWave Visualizer http://eric-blue.com/2011/07/13/neurosky-brainwave-visualizer/ [Installation] Currently there is no installer. You can download the source and/or binary distribution: the primary executable (mindstream.jar) is located in the dist directory. There are helper scripts to execute loading the app (mindstream.sh for Linux/Mac and mindstream.bat for Windows). Both scripts simply execute ( java -Djava.ext.dirs=lib -jar dist/mindstream.jar). [Current Status] - Alpha state - Streaming only supports writing to a CSV file - Tested on Linux and Windows with Java 1.6 and the MindWave headset [Change Log] - 07/24/11 - Initial release - 12/04/11 - Fixed issue reported with saving CSV file (Thanks to Pei Yin) and added some exception handling messages - 07/07/12 - Added bug fixes from jomack and added additional error checking for issues on other platforms (e.g. Win7) - 01/26/14 - Tested with sample output from MindWave mobile
