BrainAccess Mobile App
The BrainAccess Mobile App is an application for Android devices that can be used to collect data from BrainAccess devices and either re-stream it to the Wi-Fi network or save it locally on the device.
Lab Streaming Layer Integration
BrainAccess Mobile App collects data from BrainAccess devices and re-streams it to Wi-Fi network using LSL protocol. Therefore, the data stream can then be caught by another software running anywhere on this local network. BrainAccess Board software or other third party software supporting LSL could be used for this purpose. The LSL also ensures data synchronization between different data streams, for example, if there is additional stream annotating stimuli events, it would be synchronized with EEG data from BrainAccess devices.
Local Data Storage
The data acquired by BrainAccess Mobile App could be saved locally on the mobile device. This allows for truly portable recordings without any need for WiFi connectivity. The data is stored in the standard .bdf format.
Hyperscanning Capabilities
The use of BrainAccess Mobile App enables easy scale-up of hyperscanning experiments. Each BrainAccess device could connect to a separate mobile device. All these devices would then restream data to the local network and a single instance of BrainAccess Board software can collect all the streams. Read more about Hyperscanning and applications in the Hyperscanning tutorial.
Requirements and Installation
The mobile device should have an Android 9 or newer operating system installed. The app can be downloaded from the Google Play store.
