Thumb switch so far

The thumb shift keyboard is an original keyboard developed in conjunction with Fujitsu’s “OASYS 100” Japanese word processor release, and was developed by Yasunori Kanda, the creator of OASYS.

For personal computers, thumb shift keyboard models are also available for the FM16 and FM TOWNS series. Adopted in the FMR series of January 1987. Since October 1993, it is also included in the FMV series.

The feature is that it is equipped with a unique key called “thumb key”, and you can directly input Japanese (reading) by pressing the “thumb key” and “other character keys” at the same time. Two kana are written on top of the key, and when you enter the top engraved character, just press the key. In the case of characters engraved at the bottom of the top of the key, you can enter by pressing the thumb key with the same hand at the same time between the two thumb keys. Also, the voiced and handakuon characters are entered by pressing the thumb key at the same time with the hand opposite the character key.

Many people use it as a keyboard that can enter Japanese efficiently, and many writers used it as well. Also, it was once considered the number one keyboard in the word processor test pass rate, and OASYS, which adopted a thumb-switch keyboard in the word processor contest, sometimes dominated the top.

According to Fujitsu, “Romaji input requires that the sound (reading) of the words that come to mind be converted to Romaji in the head, but with the thumb scroll keyboard, that is not necessary, and by adopting the method Simultaneous input, the keystrokes There is an advantage that the number is small. Also, compared to the input of kana, the character keys are grouped into three upper and lower stages, so you can enter hiragana without moving the hand from home position. You can also enter with a simultaneous keystroke. Also, you can enter the number at the top without switching to alphabet mode, which is very convenient when you don’t have a ten “key.

In March 2010, “OASYS 100 and Thumb Scroll Keyboard Prototype” were certified as heritage information processing technology by the Information Processing Society of Japan.
