BDS (Brain Direct interface System)
The second half of the experimental HMI (human-machine interface) developed for the YF-21 variable fighter built by General Galaxy in 2040. The Brain Direct interface System responded to the brainwaves of the pilot allowing him/her to send control commands to the YF-21 at will. This system improved pilot response time considerably bypassing the delay of nerve impulses and instead responding to the commands of the pilot's brain directly. Unfortunately the BDS system proved unreliable and was never pursued for mass production. However, some advances gained by the BDS technology were eventually refined and integrated into future variable fighter HMI, such as the EX-Gear control system of the VF-25 Messiah and the cybernetic virtual cockpit of the VF-27 Lucifer.
