● Unlike pinyin method (a pronunciation

● Cangjie is based on the graphological

7. Quick 速成
● Quick is a easy version of Cangjie,
● users input first and last code of original
Cangjie codes.
● and lookup candidate list of possible
Chinese characters, to select the
character they want to input.

8. Input methods in different
Chinese worlds
● Hong Kong is much different than China (the
mainland) and Taiwan.
● Hong Kong Chinese computer users uses
Cangjie and Quick for over 30 years.
● Pinyin is the most popular Chinese input
method in Taiwan.
● SCIM and GCIN are popular chinese input in
traditional chinese world (Hong Kong and
Taiwan).

9. Problems in IBus
● In ibus, cangjie and quick is provided by
ibus-table, but certain problems occurs
in ibus to use
● For Quick on IBus, number of character
candidates per page is 6, and
traditionally is 9 for many years.
● And showing order of character
candidates in Quick on IBus are different.

10. Quick in GCIN

11. Quick in old ibus-table

12. Modify a value in ibus python
code

13. 9 candidates after modification

14. Solution
● ibus-cangjie – a seperated IBus input
engine for Cangjie and Quick by Mathieu
Bridon.
● libcangjie is a cangjie library used by
ibus-cangjie, developed by Wanleung
Wong.
● And Allan helped to add ibus-cangjie to
input method selection panel in GNOME.

18. Future
● In the future, we will bring another HK
Chinese open source input method to
ibus and GNOME, it is stroke5.

19. Strokes in Chinese

a chinese input method which its table is
inputted by Hong Kong seniors

21. Stroke 5
● a chinese input method which its table is
inputted by Hong Kong seniors
● with around 5,000 daily-use Chinese
characters.
● The idea and project is proposed and
coordindated by a social worker since
2001.

22. 5 different strokes
● Using " N M , . / " to represent 5 different
strokes of Chinese character in Stroke5,
which is equal to:
● "Horizontal", "Vertical", "Falling
leftwards", "Dot", "Curve"
● 橫 , 直 / 豎 , 撇 , 點 , 曲

23. Targeted users of Stroke 5
● It is suitable for seniors, stroke patients,
and children.

So, we hopes GNOME will be a favourite
desktop enviornment again in CJK world. :)
