The real secret of the Qeng Ho version was that no added interface was necessary, for output or input. If you knew the secret, you could access the Qeng Ho localizers directly, let the localizers sense your body position, interpret the proper codings, and respond with built-in effectors. It didn’t matter that the Emergents had removed all front-end interfaces from the temp. Now a Qeng Ho interface was all around them, for anyone who knew the secrets.
