ATTENTION: You will need the hardware - GSR.Neo. You can order it online at https://www.ebay.com/itm/263272231456?. The proposed system allows for effective biofeedback sessions to reduce stress more than ever simply and easily! No need to listen to the tiresome sound tone, you do not need to monitor the measured values of skin resistance or the changes in the signal curve, etc. In addition, there is no need to conduct preliminary baseline measurements and training sessions. With this system, you simply immerse yourself in multimedia environment (video and audio) and manage it by changing the signal. The small, hand-held and self contained GSR.Neo is a Galvanic Skin Response monitoring device. It precisely monitors your stress levels by translating tiny tension-related changes in skin pores into a signal. Relax & Calm NEO is designed for use with the GSR.Neo to do galvanic skin resistance biofeedback. Biofeedback is to control the video (as the process of achieving the goal of the game, for example: set the sun over the horizon, stop ripples on the water, stop the movement of the clouds, etc.) and audio (volume level decreasing) by changing the signal. You will learn to change the signal and lower your stress level. There is a number of video (using in one of the two modes) and audio items available in the App. The App allows add videos (specifying name and one of the two modes of use) and audio tracks from user’s Media Library to use them, along with embedded ones. Also there are opportunities to manage the database of saved biofeedback sessions and graphically represent their results. The application help contains links to embedded documents: "Specifications and features", "Quick Start Guide", "Battery Replacement". This version of the application does not require activation.
