ABSTRACT:
A method for positioning measurement sensors on the human head in which the surface of the head is partitioned into geodesic triangles by elastic lines connecting the sensors in a mutually-balanced tension network. The number of regularly-spaced sensor positions is selected by varying the number of geodesic partitions of the basic triangles of the icosohedron (10) or dodecohedron that form the initial solid polygonal partitioning of a sphere. The hemispherical structure of the network may be anchored at the perimeter by a headband (11). As the network is applied to a person's head, its balanced tension lines systematically conform its geodesic structure and thus the sensor positions, to achieve an even surface distribution of the sensors for that person's unique head geometry.
