This paper presents a preliminary evaluation of a computer data entry device called Infogrip Chordic Keyboard. Learning time, typing speed and accuracy, and operator discomfort are examined. The result shows that the 30 chords can be learned in two hours. The subjects could type 49 characters per minute with the accuracy of 98.3 percent after two hours training.
