Overview
The "HEG" in HEGduino stands for HemoEncephaloGraphy, a non-invasive biofeedback method. HEG detects regional changes in the brain’s energy consumption via changes in blood-oxygen. HEGduino enables you to see in real time how your brain blood-oxygen levels respond to your thoughts and actions, resulting in a simple and elegant biofeedback system. You can easily affect and eventually control regional blood flow in your head by focusing, breathing, and relaxing, and watching the response on your screen. With the biofeedback provided by HEGduino, you can exercise your brain and make it healthier with mindful practice.
The project HEGduino and its creator Joshua Brewster are endorsed by Stephanie DuPont, President of the Biofeedback Institute of Los Angeles, and colleague of the original inventors of HEG. HEGduino now has BioEra support, and more on offer soon thanks to collaboration with Statechanger Brazil and other developers.
Software
The HEG is controlled and interacted with via Wi-Fi, Bluetooth or USB. The device will be accessible over Wi-Fi, with an HTML interface and a free game served right from the device to whatever HTML5 compatible device is connected!
The makers of HEGduino also released a free Chrome Extension that allows Bluetooth and USB connectivity, as well as enabling 2D and 3D assets that can’t fit on the device’s memory. You can find this and all HEGduino documentation on their GitHub page.
