The present disclosure describes a manufacturing method for seaming materials. The process may be suitable for manufacturing high performance projection screens using a number of methods including, but not limited to, conventional (convert-before-coating) methods, or convert-after-coating methods. An objective of the present disclosure is to identify a process which may substantially minimize distortion of the local surface normal in the vicinity of the join.

An optical positioning aiming system including an optical positioning subsystem (subsystem). The subsystem is configured to determine relative positions of a weapon and a head mounted display. The subsystem includes a processing unit, infrared (IR) emitters mounted to a weapon, IR emitters mounted to the head mounted display, IR cameras mounted to the weapon, and IR cameras mounted to the head mounted display. The IR cameras mounted to the weapon are configured to determine a relative position of the IR emitters mounted on the head mounted display and to communicate the relative position of the IR emitters mounted on the head mounted display to the processing unit. The IR cameras mounted to the head mounted display are configured to determine a relative position of the IR emitters mounted to the weapon and communicate the relative position of the IR emitters mounted to the weapon to the processing unit.
