For 300,000 people who suffer from wearisome and monotonous work on the computer new ergonomic developments may prove to be the only solution.

Microsoft`s Natural Keyboard has become one of the most widely purchased of ergonomic keyboards. The figures and letters are devided into three serpentine sections in order to ensure that the wrists are in their natural position.

The Lexmark firm also took a fairly creative approach to the development of the keyboard two parts of which are joined with hinges so that the user can position them at a convenient distance. The keys are positioned close to one another so that the fingers experience less strain during work.

The “mouse” developed by the Logitech firm and known as Mouseman has special indents for fingers, an assymetrical form for the right or left hand, and also, a slant for the realms. Microsoft`s elongated Home Mouse has been designed specially to fit into different-sized hands, that is why it can be easily used for children,”lefties” and “righties”. The keyboards of the Microsoft company have very light keys to relax hands while typing.

Besides these ergonomic pluses the new products also have a number of other advantages.

CHANGING KEYS: THE MORE CONVINIENT………………………. (1)

When the typewriter was first invented in 1867, the letters on the keyboard were arranged to slow down the ………. (2) typist. Why? If typists went too…………(3), the keys would jam, so letters that were usually next to each other in a word were placed far apart on the keyboard. However, when the electronic typewriter was introduced this was no longer a problem, so a new one, called the Dvorak keyboard, was introduced. It had the letters that normally followed each other next to one another. It was ………. (4) than the old one. But …………….. (5) is not the best for the simple reason that generation of typists were used to their QWERTY system (named for the six letters on the typewriter keyboard).

An average typist can type as ……… (6) as ….. symbols a minute. Now a new keyboard has been developed to help users avoid carpal tunnel syndrome caused by continuous flexing of the wrist. Will it enable us to type a bit ……….. (7) ? Will it replace the entrenched QWERTY keyboard? That depends on the users.
