The DataHand is an unconventional computer keyboard introduced in 1995 by DataHand Systems, Inc, designed to be operated without any wrist motion or finger extension. It was invented by Dale J. Retter and produced by Industrial Innovations as early as 1992. It consists of two separate "keyboards", one for the left hand and one for the right. Each finger activates five buttons: the four compass directions as well as down. The thumbs also have five buttons: one inside, two outside, up and down.

The layout is initially similar to a QWERTY keyboard, but the middle two columns of keys (i.e. H,Y,G...) have been delegated to sideways finger movements, and all of the keys outside of the main three rows are accessed through two additional modes, including a mode for mousing. There are three primary modes all together: letters, number and symbols, and function / mouse mode. Some practice is required. However, eventual typing speedups are possible.[citation needed]

Rather than being spring-loaded, the buttons are held in place with magnets and are activated using optical sensors. This was done in order to reduce the finger workload while still giving tactile feedback. The button modules in which the fingers rest are adjustable—each side can be independently moved vertically or forward and back.

After the initial prototype was released in 1995, DataHand released the Professional and Professional II models with new bodies. The Professional II also has extended programming capabilities over the Professional, being able to record macros of keystrokes for convenient use.

DataHand Systems, Inc. announced in early 2008 that it was ceasing to market and sell its keyboards. The company web site states that due to supplier issues, the company will not sell the DataHand keyboard "until a new manufacturer can be identified". However, the company plans a final, limited production run to satisfy existing customers. In January 2009, the company's website started taking orders for a "limited number of new DataHand Pro II units".
