Electro-Neuron-Synapse-Interface

Electro-Neuron-Synapse-Interface (電気ニューロンシナプスインターフェイス/Denki Nyūron Shinapusu Intāfeisu, shortened as ENSI) is a type of brain–computer interface based on the Connection for Flight Interface system. The ENSI system allows a computer connection to be established between a pilot's neural synapses (hence the ENSI's name) and his aircraft's systems, thereby allowing mental control of the aircraft.

Development history
The COFFIN system first saw combat use in the year 2020 during the Leasath-Aurelian War, exclusively employed by then-prototype mainframes such as the XR-45 Cariburn and the YR-302 Fregata. Early COFFIN models from the era were simply sealed armored cockpits connected to a televison screen system installed in the aircraft's exterior, the aircraft's flight components unaffected. The Electro-Neuron-Synapse-Interface system was originally devised to enhance the COFFIN hardware by removing all components (in this case, the HOTAS (Hands On Throttle and Stick) system) needed by a pilot to physically input commands into his mainframe, and replacing them with neural synapse-to-aircraft control technology. ENSI (and by extension, COFFIN) remained as experimental technology in the decades following the South osea debacle, and it wouldn't be until the early 2040s that the former would become standard hardware for all civilian & military vehicles using COFFIN.

Standardized ENSI
The first and most common variant of the Electro-Neuron system, the Standardized ENSI is the default hardware integrated will all COFFIN-operating vehicles. The S-ENSI proved to be far superior to the standard HOTAS system, mainly because of the lack of hardware needed to calculate control inputs, resulting in increased pilot reaction time. For control, S-ENSI vehicles employ a pair of black spheres, each one placed on a side of the driver's seat/cockpit, which transmitted neural information into the vehicle's onboard computer, which performed the actions inputted by the pilot.

As well, it was discovered in the 2040s that, through the use of the Inter-Satellite-Network, an individual was able of remotely controlling an aircraft from anywhere in the world, a method of flying that was used in prior years. However, remote flight was discouraged from becoming standard combat hardware thanks to the aircraft's susceptibility to hacking, as well as the reduced response time in comparison to the manually operated version.

Opto-Neuron-Synapse-Interface (ONSI)
Opto-Neuron-Synapse-Interface (光ニューロンシナプスインターフェイス/Hikari Nyūron Shinapu Suintāfeisu, acronym ONSI) is an advanced ENSI variant, designed to further enhance the original model, which allows the pilot to link his brain directly to the aircraft, the latter then serving as the main COFFIN processor unit, an act that would have the aircraft's hardware become part of the brain's neural synapses. Special surgery is first required to safely operate ONSI; however, the process is extremely dangerous, for the procedure requires an special connector to the placed in the upper area of the subject's column, which would be later connected to the brain's neural system. Furthermore, the ENSI connection would increase the brain's activity to an alarming rate due to its flight reorientation, which can potentially lead to brain damage, or lose control of the plane in case the system was ever hacked.
