Engineers at Samsung have successfully launched an application and made selections on a Galaxy tablet by concentrating on a blinking icon. Whilst the technology is years away from general use and currently requires the user to wear a cap studded with EEG (Electroencephalography) monitoring electrodes that record brain activity, the concept that once only existed in science fiction is progressing faster than most people realise.

Samsung’s Galaxy S4 smartphone already allows users to control the screen using their eyes. With “smart pause” users can pause a video by looking away from the screen. Another feature allows users to scroll through content using just eye movement.

Insoo Kim, Samsung’s lead researcher believes thought control is a natural transition for interacting with devices.
“Several years ago, a small keypad was the only input modality to control the phone, but nowadays the user can use voice, touch, gesture and eye movement to control and interact with mobile devices… adding more input modalities will provide us with more convenient and richer ways of interacting with mobile devices.”

I’m looking forward to the time when I can think about a bacon and egg sandwich and as if by magic one appears, with crispy bacon, freshly baked bread and a little bit of tommy sauce. Now that would be impressive!
