The measurement is done so that a person sits normally by a table and takes ‘the thinker’ position (statue by Rodin) but leaning V1bes with the silver antenna horizontal against the forehead. The sensor is placed right above the so called brow ridge on the forehead. Most people have a small bump in the forehead there and the antenna fits into this bump. By always using the same place for V1bes, one can ensure reliable and consistent measurements.
