Ergonomic keyboard arrangement / 2293367
Keyboard is divided to two sections disposed correspondingly to anatomical peculiarities of arm's wrist. Keys are grouped according to purpose and character of application. Mutual disposition of keyboard modules in section corresponds to position of any finger of operator, which position the fingers take at natural relaxed state relatively each other. Keyboard modules in first group are disposed in parallel or radial at small angle to each other within limits of value of possible adjacent angles among elongated fingers. Keyboard modules of second group are disposed within range of movement of thumb. Several functions of keyboard are brought in coincidence.
