Ten or more years ago, the notion of human and machine interfaces was the field of much research and exploration. Testing and developing the system that was known as the human-machine interface (HMI) had been one of the popular trends where machine developers raced to implement the technology onto their system designs.Now, the system developers are talking about machines that would have some degrees of awareness. In other words, the machines will have some built-in intelligence as the results of implementing self-awareness computing. One can readily find industrial robots that would reduce their motion’s speed upon detecting the presence of human operators nearby. It is forecasted that there will be about two million units of an industrial robot in operational by the year 2017. By the same year, all industrial robots should expect to possess functional self-awareness modules.
