An Implementation of the TRON Keyboard
Two important objectives of keyboard input method are to gain speed and to lessen the fatigue of operators. The TRON keyboard layout is based on the data of the physical size of hands of Japanese. Firstly, physical placement of keytops which are easy to strike and causes less fatigue was determined using the data. Secondly, character frequencies in real documents was used to decide the final location of each character in the keyboard. In addition, an electronic pen is proposed for figure input.
Oki Electric Industry Co., Ltd. has built a TRON keyboard prototype on the basis of the TRON keyboard specifications. This paper discusses the design of the keyboard that reflects the TRON specifications for its implementation as a product.
