GENERAL DESCRIPTION OF THE DEVICE

Callibri is a massive project intended to create a versatile portable wireless sensor with an extensive set of features and functions in the form of an SDK. Currently, Callibri sensor is the basic element, which is used to create a wide range of products and technologies.

Furthermore, Callibri sensor can be considered as the foundation for various startups of other companies, which develop applications and programs in order to process electrophysiological or biomedical signals.

Callibri is able to work with both personal computers and smartphones. The sensor can be connected to a personal computer using one of the wireless interfaces: the proprietary one (2.4GHz) or Bluetooth connection.

This document covers the wide range of products developed for such mobile platforms as Android and iOS. The connection between the sensor and the smartphone is carried out using Bluetooth LE interface.

Callibri is offered in two different versions:

• for electrophysiology

• for electromyostimulation (EMS).

Callibri for Electrophysiology

This version of the sensor can be used to register the following signals:

• any types of bio-electric potentials (EEG, EMG, ECG or rheography);

• the angular speed and the angular acceleration, as well as the angle of the horizon deviation using the triaxial MEMS-sensor (having a gyroscope and an accelerometer).

All bio-electric potentials are registered using a separate lead from the termination pads of the sensor, or by using a special USB cable connected to the device.

Callibri for Electromyostimulation (EMS)

This version of the sensor offers the following functionality:

• the angular speed and the angular acceleration, as well as the angle of the horizon deviation using the triaxial MEMS-sensor (having a gyroscope and an accelerometer);

• creation of the electric stimulus.

A special USB-cable is used for the electrical stimulation. Device termination pads can be used to fix the sensor.

ELECTROPHYSIOLOGICAL PRODUCTS

Software development kit (SDK)

SDK is a software development kit, which allows software experts creating various applications for Callibri hardware platform. By using Callibri sensors and the provided SDK one can create the following electrophysiological products:

1. Neural interfaces based on the biofeedback.

2. Fitness and sports training quality assessment system.

3. Various applications based on the registration of EMG, EEG, ECG and the pulmonary rheogram (respiratory movement).

You can introduce with SDK manual from this link Neurotech SDK Manual

Performance potential

• The device can be connected and disconnected

• The information about the current state of the device can be received

• The information about the current battery level can be received

• The information about the functional abilities of the device can be received

• The sampling frequency can be set and received from the device (125Hz, 250Hz, 500Hz, 1KHz, 2KHz, 4KHz)

• The process of signal reception can be launched and stopped

• The information about the signal length can be received

• A required part of a selected range (or the entire signal) can be received

• The user is able to receive/set the amplification/shift of the data

• The angle of deviation from the vertical/horizontal for a specific axis can be calculated

• The signal spectrum can be shown

• BFB-indexes for specific frequencies can be calculated

• The heart rate and the tension index can be calculated (using ECG)

• The system can use both preset and custom filters

Tarhet audience

This set can be used by mobile application development teams working in the field of Life/Health Tracking for fitness, sports, current health state monitoring and the self-adjustment using the biofeedback methods.

It can be used by any other projects, which require a high-quality electrophysiological signal and estimate indicators (the heart rate, the signal power-density spectrum for a specific frequency range of EMG and EEG). For example, such projects may include new developments in the field gaming industry or BCI-related solutions.

Callibri biofeedback

Biological feedback or biofeedback is a technology that includes a wide complex of research, nonmedical, physiological, preventive and treatment procedures, which is used to represent the information about the current state and changes of various physiological processes using an external circuit of feedback.

The main goal of the project is to create a user-friendly Biofeedback application based on Callibri sensor. Relying on the vast experience in the field of Biofeedback systems creation, we create an application for the most common users. Easily understandable representation of various physiological indicators in the form of a game or multimedia content allows the user to understand how to feel and control such indicators. By using various internal mechanisms of the adaptation to the physiological signals of a specific user, the system is able to change the level of game complexity. Such approach allows keeping the high level of motivation throughout the training session.

Developed "Callibri – Biofeedback" neural feedback system is intended to be used in comfort condition of the user’s home. In addition to the implementation of the wireless Callibri sensors, this application provides an extensive library of different methods, which can be selected in accordance with the needs and requirements of the user.

The first version of the system is equipped with one Callibri sensor. It interacts with the application, which provides a wide range of muscular (EMT) or psychoemotional (ECG and EEG) training session. Each method has a specific set of games and training recommendations, including information about the location of the sensor and the process of playing.

The list of games and training methods is constantly updated using the server part of the application. The training results are also saved on the server and linked with the account of the user.
