A group of researchers from the Stanford University created a spray that turns your hands into a keyboard with Artificial intelligence.
A kind of invisible glove, this spray forms an electrically active intelligent skin that deciphers handwriting, sign language and the shape of a familiar object. After applying it, a simple movement of the hands generates the response.
The material, which is biocompatible and stretchable, it is sprayed on the back of the hand, like a bronzer. In the mesh is a small electrical network that detects how the skin is stretched and folded. An air net module is attached to the forearm for rapid learning.
Thanks to Artificial Intelligence in the network, researchers interpret various daily tasks, based on hand movements.
This is how the “invisible gloves” work that turn your hands into a keyboard with Artificial Intelligence
Zhenan Bao, professor of chemical engineering, is the lead author of the study, published in the journal Nature Electronics.
“As the fingers bend and twist, the nanowires in the mesh are squeezed and pulled apart, changing the electrical conductivity of the mesh. These changes can be measured and analyzed to tell us precisely how a hand, finger or joint moves.” explains Professor Bao.
With machine learning from Artificial Intelligence, computers monitor changing patterns in the conductivity of the hands, assigning those changes to specific gestures and physical tasks.
The example the researchers put forward is this: type an X on a keyboard and the algorithm learns to recognize that task from the changing patterns in electrical conductivity, produced by the spray. When the algorithm is fully trained, the physical keyboard is no longer needed.
In addition to Zhenan Bao, other Stanford scientists worked on the research, such as Kyun Kyu Kim, Min Kim and Samuel Root, among other colleagues.
