Ring is a mobile and reliable biosignal device for the monitoring of electrodermal (EDA / GSR) and cardiovascular activity (BVP). It has been designed for real-world research scenarios that require great comfort for the user as well as an agile set up and outstanding signal quality for the researcher. The device has an ultralight and comfortable design with two key biosensors for a basic estimation of emotions (GSR-electrodermal activity and BVP-cardiac activity) and a three-axis solidary accelerometer (ACC) for an estimation of the noise that can be generated due to the movement of the hand. Its stable mechanical design provides outstanding robustness and signal quality, even with movement or during long recording periods.
Owing to its exceptional usability, reliability and the possibility of self-positioning by the end-user, an infinite range of possibilities to use it both in and outside of the laboratory with ecology are available.
Ring comes with the Bitbrain Software Kit for data acquisition and programming, which has a large compatibility with real-time I/O and third-party data processing (LSL, Matlab, Python, BCI2000, OpenVibe, etc). Also, by acquiring the Human Behaviour Research Lab, it can be performed a seamless synchronisation with other human monitoring technologies such as EEG, eye-trackers, indoor positioning system, among many others.
Wireless, mobile, compact and ultralight (60gr). It is adaptable and adjustable which ensures comfort. Final user can set it up in less than 10 seconds. No maintenance and easy to transport.
Integrated sensors to reliably monitor skin conductance (electrodermal activity - EDA / galvanic skin response - GSR) and cardiovascular (blood volume pressure - BVP) activity. The sensors are located on the fingers’ first and second phalanges (optimal measurement points). This biosignal device also mitigates artefacts produced by finger movements thanks to the three-axis solidary accelerometer (ACC).
Quick installation by the end user in less than 10 seconds, allowing a fast, simple and reliable physiological data collection. It comes with an intuitive software to collect data with the help of visual guides, thus ensuring quality assembly and monitoring.
