Out in the news this week was a rather novel idea from the University of Arizona. Immigration interviews may never e the same again if the idea of automated lie detector tests takes off. The machine could ask the passenger a series of questions, and analyse different aspects of your behaviour: how your eyes are moving, how your voice changes, how you pause between answers, how you fidget.
The machine, an “Embodied Avatar kiosk” uses this data to assess how truthful your answers were. Whilst this is the latest technology in the field, it is unlikely to be at Gatwick in the near future. You are much more likely to start to see more of the automated border control systems in place!
