Claim 8:
9. A system for detecting a blind spot area of a vehicle, comprising:
a sensor system configured to provide head position data associated with a head of a driver of the vehicle;
a data storage system configured to provide pillar position data associated with at least one pillar of the vehicle, wherein the pillar position data includes a coordinate of a first point associated with a first edge of the at least one pillar and a coordinate of a second point associated with a second edge of the at least one pillar, wherein the first edge is a front edge that faces a forward direction of the vehicle, and wherein the second edge is a back edge that faces a backward direction of the vehicle; and
a processor configured to receive the head position data and the pillar position data, determine at least one angle based on the head position data and the pillar position data and further based on:, θ
