How is the DataHand ergonomic keyboards mouse controlled?
The mouse control is based on the same principles as the DataHand ergonomic keyboard; minimal finger movements and minimal forces are required, and the operator’s fingers do not need to leave the home row of keys. The upper body musculoskeletal involvement commonly necessary to operate traditional, accessory mice is eliminated. When mouse mode is entered by activating the Function/Mouse mode switch on the right thumb, the keys surrounding the index fingers become active for mouse or cursor movement. DataHand mouse movement emulates a traditional mouse—but with the unique DataHand ergonomic benefits. When used together, the speed of the two fingers is additive, offering a third speed. To left click, press the left index finger down key and for the right click, press the right index finger down key. To leave mouse mode, the left thumb up switch is used to return to normal mode. The operator’s fingers do not need to leave the home row of keys to operate the DataHand mouse! On other keyboa
