Human laughter can be used in biometric security. According to scientists from Nigeria, it can become an analogue of a fingerprint reader, iris or retina of the eye, as well as a voice-activated system.
People can be identified by the incomparable nature of their laughter. Unlike voice and mannerisms, laughter is nearly impossible to imitate. This conclusion was reached by scientists from the Department of Systems Engineering at the University of Lagos in Akoka, Lagos, Nigeria. They demonstrated this in a study
published in the International Journal of Biometrics.
Scientists have identified different sound frequencies in human laughter that can be used to create a digital signature. They found that their prototype recognition algorithm was 90% accurate.
Experts from the Systems Engineering Department concluded that laughter is a viable biometric function that can be used to identify individuals in AI systems.
Earlier, scientists from the University of Nottingham said that classes with a designer and a mirror can be very useful for doctors working with the local
ultrasonic anesthesia. These simple objects allow you to work out the interaction with three-dimensional objects and their two-dimensional images.
