The fact that the footprint computers for has gotten so small as your smart phone does practically everything that a desktop computer will do, validates Gordon Moore’s prediction also referred to as Moore’s Law, that “the number of transistors on a chip will double approximately every two years” (Intel, 2011) Computer Human interaction has been in the forefront of technology for many years. Much progress has been made in this area and the applications related to this technology have been greatly improved. Eventually, I believe the keyboard will disappear and interacting with computers will be all touchscreen.

Speech recognition software has gotten to the point where it is almost flawless. Back in 1982 when Dragon Naturally speaking was introduced to the market, it was not nearly as functional as it is today. I actually used the program during that era (1988) and continue to use it today. The most significant improvements I realized were the ability to identify the words being spoken. In the beginning days of this program I made many more errors than today. You actually had to speak very slowly and the word annunciation had to be very accurate. But, for that time and having nothing to compare it to, the idea of the program was awesome. This is where Moore’s Law has shown its effect.

“Speech & Voice recognition refers to the ability of machines to respond to spoken commands. Speech and voice recognition enables “hands-free” control of various electronic devices—a particular boon to many disabled persons—and the automatic creation of “print-ready” dictation” (1 Focus Medical Software, 2013). This ability has made it considerably easier for disabled or impaired people to accomplish what would otherwise be considered an undoable task. The progression of the software parallels what Moore set the standard to accomplish. Today,...
