Head-based targeting with pitch amplification

A gaze vector of a human subject is translated to a targeting vector that defines focus within a graphical user interface. Sensor data is received from a sensor system indicating pitch angle of a head of the human subject defining the gaze vector. The pitch angle is translated to a scaled pitch angle according to a pitch scaling function that increases amplification of the pitch angle in one or more directions as the pitch angle exceeds a start angle threshold in each of the one or more directions. The scaled pitch angle is output as a component of the targeting vector. 人类主体的凝视向量被转换成定义图形用户界面内的聚焦的定标向量。从传感器系统接收指示人类主体头部的俯仰角(定义凝视向量)的传感器数据。根据俯仰缩放函数将俯仰角转换成经缩放的俯仰角，该俯仰缩放函数随着俯仰角在个或多个方向中的每者上超出起始角度阈值而在该个或多个方向上增大俯仰角的放大。经缩放的俯仰角被输出为定标向量的分量。
