U.S.アマゾンで面白いテンキーを見つけた。
親指でtabキーを押せるようになっているテンキー。
親指でキーを押す配置は左右分離キーボードで有名なHelixなどではよく見かける。
しかし、量産品のテンキーではかなり珍しい。
近い将来、歴史の波に消えそうな気がするので、その前に記事にした。
ちなみにアマゾンでの取扱開始は2016年で価格は30usドルほど。
このテンキーの基盤と外側とをマイコンarduino Leonardoに繋いで「偽Helix」を作り、片手キーボードにできる。
この意味で、この形の量産品には価値があると思う。

I found an interesting numeric keypad on U.S. Amazon.
It is a numeric keypad that allows you to press the tab key with your thumb.
The thumb-press key arrangement is often seen in Helix, which is famous for its separated left and right keyboards.
However, it is quite rare in mass-produced numeric keypads.
I feel that it is likely to disappear into the waves of history in the near future, so I wrote this article before that happens.
By the way, Amazon started carrying this product in 2016 at a price of about $30US.
Using the base and the outside of this numeric keypad, the microcontroller is an arduino Leonardo, and by connecting it to the arduino Leonardo, a one-handed keyboard with a "fake Helix" can be easily built.
In this sense, a mass-produced product of this form would be worthwhile.
