It could be one way telepathy where the machine reads your mind, but can't send back info.It's just that if telepathic interfaces existed, there would be nonverbal communication, too (even if rudimentary, such as "Now!"). But there never is - the characters still speak, whisper, nudge and wink in a tight spot. Excusable on occasion, but in a contemporary action flick it would be inexcusable for characters not to utilize, say, their mobile phones.

Humans by nature aren't a telepathic race.
Think of it as a less invasive form of Synaptic Transceiver.
