19. A seat belt sensor assembly comprising:
a seat belt webbing;
a human machine interface on the seat belt webbing comprising a plurality of force sensors coupled to the seat belt webbing, wherein the force sensors capture force levels applied to a surface and a different side of the force sensors and transmit the force levels as capacitive measurements to an electronic control unit,
wherein the electronic control unit comprises a processor communicatively coupled with a memory, the memory storing computer-readable instructions that implement software with the processor; and
a map of force sensor locations on the seat belt webbing stored in the memory,
wherein the processor of the electronic control unit executes the software to:
receive the capacitive measurements from the force sensors;
calculate capacitive response tracking data according to the map of force sensor locations;
identify user commands from the capacitive response tracking data; and
control a vehicle system with the user commands.
