High Quality Content by WIKIPEDIA articles! The DataHand keyboard was introduced in 1995 by DataHand Systems, Inc. Before that it was produced by Industrial Innovations as early as 1992. The keyboard consists of two completely separate "keyboards", one for the left hand and one for the right, that are molded to rest your hands in. This allows you to place each hand wherever it is most comfortable to you. Each finger activates five buttons, the four compass directions as well as down. The thumbs also have five buttons as well, one inside and two outside as well as up and down. The button modules in which the fingers rest are adjustable to best fit the user's hands - each side can be independently moved up and down, towards the palm or further away.
