Even though technology is rapidly evolving cell phones, tablets, T.V., and computers. One thing that hasn’t change much over the years is the keyboard. There have been some design changes, but other than esthetics, nothing has been done to launch the keyboard into the “future” since 1873.

Most keyboards look like this…You’ll notice that the arrangement of the keys is not alphabetical.

The introduction of QWERTY helped people type fast and with far less jamming interfering with their work. A few years later, the introduction of “touch typing” increased typing speeds further.

With touch typing, users are trained to rely on muscle memory instead of sight. The fingers on each hand are supposed to rest as shown in the diagram below.

After some time spent training the hands to move around in this way, muscle memory takes over and users can type without having to look at the keyboard, achieving speeds of 60 words per minute (WPM) or more.

The F and J keys let our index fingers know if your hands are in the right spot. After each word, the hands are meant to return to the central position, using the bumps as a guide.
