A beam control apparatus consists of an electromagnetic field control component, which has a spherical cavity encircled by a transparent spherical shell, and a beam directing component, which is spherical in shape and located in the spherical cavity. The two components can rotate relative to each other. A clearance between the two components could be filled with lubricant. The beam directing component has a magnetic moment or an electric dipole moment. A controller controls a magnetic field or an electric field in the spherical cavity of the electromagnetic field control component to exert a torque on the beam directing component to control a direction of the beam directing component, thereby controlling a direction of an emergent beam. The present invention is a new terminal technology for free space optical communications, laser scanning, unmanned driving, laser beam driving and location identification.

A method for determining a current viewing direction of a user of a pair of data glasses having a virtual retina scan display. The method includes at least the method steps: projecting at least substantially parallel infrared laser beams onto an eye of a user of the data glasses, acquiring two-dimensional images from the infrared laser beams reflected back by the eye of the user, and determining pupil contours in the acquired two-dimensional images.
