1. A portable wand system comprising:
a wand applicator containing a surface treatment application element;
a wand controller subsystem coupled to the wand applicator, the wand controller subsystem comprising, a computer program, a 6 degrees of freedom inertial measurement unit (IMU), a central processing unit (CPU) coupled to the IMU, a surface treatment application element power feedback to the CPU, a memory unit coupled to the CPU, and a provided CAD (computer-aided design) model of an area with one or more surfaces to be surface treated in an interior of an aircraft with a surface treatment application of the surface treatment application element and a map of a predetermined surface treatment application of the one or more surfaces to be surface treated in the interior of an aircraft, the 6 degrees of freedom IMU measuring one or more positions of the wand applicator as it is moved by a user over the one or more surfaces to be surface treated in the interior of the aircraft;
a user input button coupled to the wand applicator;
an indicator element to indicate that the surface treatment application of one or more of the one or more surfaces in the interior of the aircraft is complete;
a power assembly coupled to the wand applicator;
one or more registration features to periodically register the wand applicator against one or more known locations and one or more known orientations at the one or more surfaces in the interior of the aircraft in the provided CAD model, the one or more known locations comprising one or more of, a starting position known location and one or more subsequent known locations, and when the user presses the user input button, the one or more registration features identify the starting position known location at one of the one or more surfaces to be surface treated in the interior of the aircraft; and
a computer recording system coupled to the wand controller subsystem, the computer recording system operable to analyze positional data of the wand applicator, and operable to communicate to the indicator element a status of the predetermined surface treatment application on the one or more surfaces in the interior of the aircraft, the computer recording system comprising a computer to record the predetermined surface treatment application of the one or more surfaces, to validate and verify that the predetermined surface treatment application is correct and complete,
wherein the portable wand system measures the positional data, orientation, duration, and output of the wand applicator in real-time, and compares the positional data against the provided CAD model, to indicate to the user when the predetermined surface treatment application is achieved for the one or more surfaces in the interior of the aircraft.
