[ça y est] Today, we control devices by thought and waves
In recent days, technological innovation seems to have turned a corner. While the manufacturer Intel has just created a Investment Funds dedicated to the computing of the senses, several impressive discoveries have been made, which could revolutionize the field of human / machine interfaces: researchers at the University of Washington have notably made it possible to remotely control electronic devices using simple gestures. Other American researchers, from the University of Minnesota, have meanwhile developed a technique to remotely control a small drone using only neuronal activity.
Wi-Fi waves that allow you to control a device remotely
Motion detection is not a new technology. We already know the Wii console, from the manufacturer Nitendo, capable of detecting the position, orientation and movements of the controller, for a more realistic gaming experience.
But the technology WiSee, developed by engineers at the University of Washington, offers an additional innovation: motion detection no longer needs a third-party device to function (such as the Wii controller), because it is provided by the presence of Wi-Fi waves. WiSee is based on the exploitation of interference caused by the human body and its movements through the waves of a Wi-Fi network. Engineers have designed software capable of transcribing this interference, according to a method that allowed them to record nine gestures. Then, when the person performs these gestures, they are automatically detected by the software, with a success rate of 94%.
Flying a drone by thinking: the fantasy of telekinesis comes true
At the University of Minnesota, a team of bio-medical engineering students has developed a revolutionary human-machine interface, allowing you to remotely control a small drone by just thinking.
The operation of this interface is based on the brain activity that occurs when we think about making a certain movement. By defining these movements with precision, the engineers sought to make each brain activity correspond to a control command: for example, when the person thinks of closing his right fist, he turns the device to the right, the same for the left. . To raise the drone, the pilot thinks of closing his two fists.
Wearing a helmet connected to a computer is necessary to make this telekinetic device work: when the pilot thinks about the movements mentioned above, the helmet sends the information to the computer, which processes them then sends the corresponding command to the drone, via Wi-Fi.
