Now operate the normal computer with hand gestures

CANADA: We know that hand gestures can capture many of the features of a computer, many of which have become systems. But thanks to the TypeLike system, computers can perform a variety of tasks with a 97% accuracy of 36 hand gestures by making minor changes to the webcam instead of expensive hardware.

Interestingly, it does not require any new hardware or electrical system. This way any desktop or laptop can be operated with hand gestures.

The TypeLike system is developed by the University of Waterloo, Canada. It has only two components. There is a small mirror that is tilted at a certain angle and placed on the webcam and the other thing is a modern algorithm or software.

Now if you want to increase the volume of the computer, let one hand stay on the computer and raise the thumb of the other hand which is called thumbs up. This way the software understands the signal and raises the volume.

The system was developed by Nellen Sheiber, a computer science student at the university. He says the webcam keeps looking at the face and the hands are hidden. That is why a slanted mirror is placed at the bottom which keeps looking at the hands.

Everyone’s hand gestures can be different and that’s why scientists created a database of hand gestures from 30 different volunteers to standardize. In this way 36 features of the computer can be controlled with 36 gestures. On the other hand, his algorithm keeps learning more.

Interestingly, in the initial experiments, the computer interpreted all these signals with 97% accuracy, which is a great achievement.
