A BMI is a direct communication pathway between brain and external device. It can collect information from the brain, for example to derive a person’s intent to move a muscle, but also feed it to the brain, for example to replace a lost sense. The goal is to increase the speed, trustworthiness and complexity of human-machine or even human-human interactions. Development goals are to improve the in situ reading of a user’s brain activity at higher resolution, using non-invasive methods and to improve understanding of brain functions using improved remote sensing methods like fMRI.
People are able to interact with others and with machines directly from their thoughts, without errors in translation and intent. Machines are able to read the thoughts, moods and emotions of humans to a detailed degree and will adjust their behavior accordingly.
