Macrotellect MindMesh Premium EEG Set for up to 25 Users

The MindMesh EEG Tracking Sets consist of MindMesh EEG headsets in the form of a headband, a Bluetooth gateway for up to 50 connected EEG devices (depending on the version) and the software for operation and analysis of the measured EEG data. Depending on the version, the sets also include various accessories, which are described in more detail below in the Scope of Delivery section.

Main Features:

MindMesh EEG Tracking allows Visualisation of EEG-Data and also provides games for interaction with group participants.

• Real-time EEG Visualisation Interface
• 3 Games for group interaction
• EEG-Data tracking reports for group or individual participants
• The software offers comprehensive reports, multi-level account management such as Institute - Coach - Class - Student and much more.
• Automatically generated EEG data reports with graphical graphs are available for evaluation.
• In addition, individual reports can be shared and printed via web sharing or raw EEG data can be generated in spreadsheet format for follow-up.

What versions of MindMesh EEG-Tracking are available?

There are 3 versions available, which differ in the number of EEG headsets, accessories and software included.

• Premium Set with 25 MindMesh modules (headsets)
• Standard Set with 12 MindMesh modules (headsets)
• Lite Set of 6 MindMesh modules (Headsets)

The MindMesh EEG Headset modules can be upgraded accordingly.

What kind of EEG data can MindMesh provide?

When connected to the MindMesh EEG-Sensors, the front end of the acquisition system simultaneously displays group attention, group relaxation and group flow data, as well as individual attention, individual relaxation and individual attention status data for each user. Rankings and trends of the data during the acquisition process are also displayed in real time on the system.

Once the EEG data has been collected, the system automatically generates group and individual EEG-Data analysis reports for the users in the back-end, detailing the changes in the EEG collection process and the scoring criteria of the data. Displayed are: Excellent, Good, Normal and Stability changes, providing users with more accurate reference points when EEG acquisition is performed on multiple subjects.

A technical description of the data rate etc. is given later in the text.

Target Groups:

School & Education: By using the MindMesh system, teachers in educational or training institutions can collect real-time attention data feedback (EEG data tracking) from multiple students in the classroom to check the effectiveness of improving teaching methods and effectively improve the quality of teaching.

Team building activities: MindMesh EEG-Sensors are used to collect EEG-Data from team members during team building activities and monitor team members' trend data during group activities to optimise team management and improve overall team cohesion and effectiveness.

What are the benefits of the MindMesh EEG Tracking System?

By using MindMesh to collect and analyse EEG-Data from multiple people simultaneously, it is possible to track the real-time status (attention) of group and individual participants. In team projects, analysis of group data can be more effective in obtaining real-time mental states and general feedback from team members.

MindMesh is a ToB solution for clients who want to track and collect EEG data from multiple people simultaneously. This includes neurofeedback training, mindfulness training, neuromarketing, meditation, education and other applications that require attention, relaxation and other brain data from multiple people.

 Technical specifications of the Mindmesh EEG Headsets:

• Number of channels Single channel.
• Signal sampling rate: 512 Hz
• Environmental filtering: 50 Hz (customers in USA and Canada please order 60 Hz)
• Signal accuracy: 0.25uV
• ADC accuracy: 12bit
• System response time: less than 2ms
• Data output: collects brain waves that directly reflect human cognitive psychological indicators, with data output frequency of 1Hz, providing indicators of concentration, relaxation, flow state, etc. Bluetooth version: 5.0
• Battery life: 2.5 hours

Note on compatibility with other Macrotellect EEG-Headsets:

The Macrotellect EEG headsets model Brainlink LITE and model Brainlink Pro cannot be combined with Mindmesh as these models do not have the more powerful chipset of the MindMesh EEG headset. These new chipsets are required to both process the measured EEG data and communicate with the Mindmesh gateway.
