ErgoMagic Sections can be separated up to 6' apart, It can also be rotated & tilted in order to allow users find their most comfortable position — for user convenience, pre-set angles are installed at 20, 30, and 45 degrees of declination. Each section is separated with a completely distinct base which allows the ErgoMagic keyboard to conform to people's differing shoulder widths.
Each of the three sections can be placed at any angle on the desktop, providing user-defined rotation to the left and right. Each section can be tilted in any direction (left, right, front and back) at 0, 20, 30 and 45 degrees.
By providing rotation (to accommodate ulnar deviation) and tilt (to accommodate pronation), each section of the keyboard can adjust to an wide number of positions which allows it to be set in a position that is comfortable for each hand of the user.
