why this project�
• The Hme before 3G �– Carriers: what’s their aLtude?
• SMS plans as strategy�• Benefits • Desktop applicaHon�
why this project�• The Hme before 3G �
– Carriers: what’s their aLtude? • FeHon‐ the IM+SMS �
No I never use
It saves money
the input is faster
the interface is more friendly
the keyboard is beVer
I don’t like switch from computer to phone when I use computer.
why this project�• The Hme before 3G �
– Users: why they using text message so much?�
The amount of short messages you send per month?
1000+
500‐1000
300‐499
100‐299 50‐99
under 50
why this project�
• The Hme before 3G �– Users: How’s current input methods?�
Are you saHsfied with the input method?
Very saHsfied
Good Just so so unsaHsfied
why this project�
• The Hme before 3G �– Carriers – Users�– Manufactories: why they developed so many input methods? • More than 1,000 ways
• 90% market share from foreign companies, where 50% from T9, a US company �
why this project�
• The coming of 3G – Why it’s important and what to do next �
The current design and the problems
• The design Process – Challenges – Research: HCI research in China – Implement balance – TesHng
The current design and the problems
• The design Process • The design
– Keyboard input • Pinyin • Stroke
– HandwriHng input – Voice input
The current design and the problems
• The design
Pinyin Stock Cang jie
Hand wriHng
Voice input
The input method you use most:
Keyboard input
• Popular keyboard input methods
Keyboard input A demo of pinyin input A demo of stroke input
Handwriting input
• The input order is important
Voice input

The current design and the problems
• The design Process • The design • The problems
– Norman’s 6 points framework • Conceptual model • Affordances • Mapping • Feedback • Visibility • Constraints
Keyboard input – ABC/English
• Mapping
Keyboard input ‐Pinyin
• Mapping
Keyboard input ‐Pinyin
• An example of improved Pinyin input by opHmizing the mapping process: intelligent word input
• Depend on the capability of the word library
Keyboard input ‐ Stroke
• Mapping
Keyboard input ‐ Stroke
• An example of improved stroke input by opHmizing the mapping process
• Depend on the capability of Character library
Voice input
• Affordances • Constraints • The challenge is the local accents – Memory – Library – Response Hme
HandwriHng input
• Feedback – The order
• Visibility – Cursive wriHng
The future
• Coming standard – The standard of Chinese input in Mobile phone would carry out by Department Ministry of InformaHon Industry.
– This informaHon was from newspaper of 2006, February.
The future
• Coming standard • Product ideas
If the following new technologies are applied to Chinese input methods, which do you like to try most?�
accurate handwriHng input
accurate voice input
easy‐operaHng copy‐paste funcHon.
word scan funcHon
customize words and phrases
auto arrange most common used words
magnanimous word library
The future
• Coming standard • Product ideas • InnovaHon points
– Analyze the current problems • Keyboard: Mapping • Voice: Affordances, constraints • HandwriHng: Feedback, visibility
Examples of improved keyboard input
Examples of improved keyboard
The Quantai Electronic company has a keyboard product, which is more specific. The BK600 Bluetooth wireless foldable keyboard support Palm, Symbian, Win CE these 3 OS. It only weights 200g and a hand size. 2 AA baVeries would provide a long‐Hme use. At the back of the keyboard, there’s a stand that can be placed on a phone.
The O2 Xda Atom Exec send out this keyboard as a gin for buying the phone. The size is similar with the phone and set as a standard keyboard. Meanwhile, some shortcut keys are added on the top, such as rotate screen, inbox mail and calendar. But this keyboard doesn’t support the pinyin symbols which may cause some difficulty when using Pingyin input methods.
The G‐tech Bluetooth wireless keyboard can be folded as cloth. It is because it designed by using cloth, expect the baVery box. This keyboard weight 68g and the baVery can stay for 20 hours conHnuous working. It supports most PDA and smart phone device. (Such as Symbian, Windows Mobile OS), and if you don’t use it, you can just fold it up and put away.
Examples of improved handwriHng
No more touch pen needed Touch pad improvement
