Research and development on the improvement of prostheses, which should replace people’s lost limbs, does not stand still. US engineers have used artificial intelligence technology to improve control of a prosthetic hand connected to the user’s nervous system.
This made it possible to control the fingers and hand of the bionic hand in a natural way with an accuracy of up to 99%. One of the volunteers even managed to play video games.
Despite the success of the experiment, not all gestures were accurate. The best results were achieved by artificial intelligence in recognizing the movements of the ring finger and little finger. It was up to 86.3% for one participant, 97.9% for the second and 98.4% for the third.
In general, the success rate for all movements was 99.2%.
The developers believe that this technology can be improved even more. This will allow people with an amputated arm to return not only motor skills, but also the ability to feel touch, vibration and temperature.
Now people with amputated limbs can be offered not only conventional prostheses, but also bionic hands that can move as the user wishes.
The simplest systems involve the execution of movements thanks to the contraction of the remaining muscles. However, it takes practice. The best effect is guaranteed by prostheses that, through the implant, form a single interface with the human brain and are controlled like an ordinary hand.
