Emotiv Systems is a company that makes products to measure how people feel. The products, called EEG (electroencephalogram) headsets, measure the electrical activity of the brain. When you wear an EEG headset, it picks up signals from your brain and sends them to a computer. The computer then analyzes the signals and can tell how you are feeling. The technology can measure things like your level of stress, energy, focus, and how your body is reacting to different emotions. With this information, Emotiv Systems can help people understand their emotions better, manage stress, and even improve performance at work or in sports and gaming.
