When it comes to the subject of home automation, this continues to be a factor that will make our everyday lives so much more convenient in the long run. On the other hand, those who have physical disabilities that limit their movement note that something as simple as being able to turn on a light can end up turning into a real challenge.
Thanks to researchers from Gazi University in Turkey, however, a unique solution may soon be on the way.
Thanks to the use of an EEG cap, a special system has been developed that will be able to detect the specific P300 brain wave activity that is generated whenever an individual is intending to perform a certain task. Generally defined, the P300 signal is a pattern of brain activity that appears whenever an individual has an intention of completing something in particular. To test this, the researchers brought in a total of five volunteers, who were then shown a display with images that were associated with specific smart home tasks. The volunteers were then asked to think about which tasks they wanted to complete, such as turning on a television, answering a telephone, or turning an air conditioner on or off.

More specifically, by flashing an image a total of five times, this was found to be enough for the system to pick up the right P300 signal approximately 95% of the time. Even better is the fact that the system itself was found to have worked for two of the volunteer test subject 100% of the time. These results were then presented at the IEEE Engineering in Medicine and Biology Society Meeting in Milan, Italy.

This is a method that involves measuring light that passes through blood vessels that are located close to the human brain in order to determine which specific areas are using oxygen on a more active basis.
As part of the initial testing, it was revealed that the system was correct approximately 80% of the time; however, overall changes in the blood to the brain never happen immediately, and as such, it ended up taking close to a total of 20 seconds for the system itself to end up responding to any kind of a change.
According to another researcher based at the University of Chicago, it is believed that both of the methods that were used are actually promising and that they also show an indication that there is a future in which brain-machine interfaces will be able to be connected to practically everything that is located within a single home.
