The device that i want to talk about is the steel sky exhibition by Christoph De Boeck. This exhibition consists of a few steel plates suspended in the sky and rigged next to a high frequency reverb mechanism. The interface is then connected to a wifi headset that gathers 8 signals of brain signals from whoever is wearing it. Using the brainwave patterns, the reverb mechanisms would strike on the metallic plates, simulating what the skies would be like if they were made out of something as dense as steel.
The technology is provided from the Holst center, which is an independent R&D technology, and is involved with wireless autonomous sensor technology. It developed a wireless electroencephalogram (EEG) headset which fits comfortably , and can monitor moods in daily life situations using a mobile app.
Our brain basically process information through electrical signals generated by electrically excitable neural network. When stimulated, molecules pass through the cell membrane and passes through the synapse, which is the gap between the neurons. This electrical signal is then picked up by the device.
The headset tracks localized and synchronized activity in the parietal lobe and the occipital lobe, and is able to track if the user is blinking, smiling, raising his/her eyebrows along with many other complicated expressions. The user would at first think about a specific action, and the resulting brain activity would be recorded and logged in a database. So whenever the user thinks about performing that same action again, the computer will take the nearest approximate value in the database and perform an action.
On a technological level, I found this interesting as the headset could potentially be marketed to the general public as a form of wireless and hands-off approach to interacting with devices, and the most amazing aspect of this concept is that it is already put into practice, with augmentations and prosthesis.
I could imagine someone registering all kinds of brain signals based on different kinds of thoughts, and then be able to open doors and cabinets without even uttering a single word or lifting a finger.
