The new method of wheelchair control can be a breakthrough for many paralyzed people. The movement of the tiny magnet in the “earring” on the tongue is enough to drive the instrument.
“Science Translational Medicine” published an article presenting a new generation wheelchair control system. The paralyzed person inserts a small implant containing the magnet. There is a sensor in the steering system that detects even the slightest movement of the muscle.
The area of the brain that is responsible for the movements of the tongue is proportionately very large. This is necessary for the proper functioning of speech apparatus. Because the language is incredibly flexible, hardware control can be extremely precise.
Another advantage of the new system is the fact that spinal cord lesions, which are one of the most common causes of paralysis, almost never come to the inertia of the tongue.
The magnet on the tongue can be used not only to control the wheelchair but also other complicated devices, including the computer.
The system was tested on a group of 34 people. Patients were delighted. They only took a few days to learn how to operate a trolley because it was very intuitive. Moving the language to the left simply means turning left and analogously in the opposite direction. However, the developers point out that the software can be freely adapted to the needs. For example, you can program a system so that when you touch a specific tooth, you have selected the phone number.
