Fr. Ahn (a retired Episcopal Church clergyman) has started an outreach ministry to newly arriving Korean immigrants to US at his church in Hollywood, California in 70’s. He was in need of publications in Korean language, including a monthly Korean language magazine, NEW LIFE, to give orientation to these new immigrants to US. The problem was how to process Korean Hangul in English word processor.

As Hangul is written syllabic characters, instead of serially writing each alphabet, one after another as in English, Korean Hangul had to stack them up by certain rules to make a syllabic character. So, Fr. Ahn started inventing a new input keyboard to run these photo composition machines. However, it was not an easy task.
In 1982, he has resigned from his church to work full time for the outreach ministry and to work on new keyboard. Next three years, he has coordinated with Dr. Gong, Byung Woo, MD, an ophthalmologist in Philadelphia, another Hangul keyboard researcher. He has concentrated in research on computer keyboard for Hangul. Until his retirement a few years ago, he has experimented and tested with more than hundred of different keyboard arrays and tested in various countries in USA, China, North and South Korea. He has completed his research work on Hangul keyboard in 2003 and patented.

Currently, his PH keyboard driver on Hangul is available on Windows 2000 and on LINUX system. With APH keyboard, you can type serially, which is at least 50 % faster than Korean Standard keyboard (hereafter called KS keyboard). Also you can type simultaneously, which is at least 200 % faster than the KS keyboard.

Since Hangul can input on computer simultaneously like shorthand machine and Hangul is invented as phonetic symbol, it can apply to any language writing systems for fast input.
