Never mind that it doesn't work, this is the supreme pipe dream for inputting Chinese characters on electronic communication and information processing devices. Of the many thousands of Chinese character inputting systems (see also here and here) that have been devised, some work fairly well and some barely function at all, but this one has to take the cake for being the most ridiculous of all. It is all the more preposterous that initially it was intended for smartwatches with their tiny glass surfaces.
The name of the system gives it away, that is, yībǐyīzì 一筆一字 ("one stroke one character").
Since the average Chinese character has twelve strokes, and many characters have twenty or more strokes, it would be utterly impossible to input the thousands of different characters with just one stroke.
You can find an index to the characters by total stroke count here.
Here's a bilingual introduction to "Ibeezi". Note that it doesn't really tell you how the system works, and it doesn't give any examples.
The official site of "Ibeezi" contains a video purporting to show you how to use the application.
Here's a comment by a gullible graduate student from China who almost got snookered:
I tried the application myself, but haven't been able to master it. Some words can be really hard to find.
It seems it's a combination of pinyin input and radical input, and I haven't found a way to input the characters by one stroke.
