In version 1.6 of EEGID (NeuroSky Mindwave Mobile Android App) that we just pushed to the Google Play and Opera Mobile stores, we added GPS recording functionality. This includes a new permission that must be accepted to run. In the interface, there is an additional button for GPS that is either ON or OFF. When selecting to turn GPS into ON mode, if GPS is not enabled in the device settings, it will prompt to direct you to that screen. For privacy issues, this setting is not saved, and must be enabled each time at the beginning of loading the app, and will always default to OFF. There is an extra column added to the CSV file called "location". If GPS is OFF, the row will be populated with "unknown". If GPS is enabled, the row is populated with "LAT: #.# LONG: #.#" where the "#.#" is the decimal form of the geographical location. These can be entered into google maps as #.#,#.# to see a visual representation of the location of capture. For those of you doing data analysis on the locations, you can use the string split functionality of your spreadsheet software to parse the location field.
For those of you who are using EEGID in a regular process, we recommend that you do not apply the update on your devices until you have tested in a non-operational environment, or at least back up the .APK file of version 1.5 before you apply the 1.6 update.
