Main features
Embedded input prediction function. Minimized operation achieves comfortable Japanese input.
Mobile Wnn V2 has various functions including input prediction and learning and optional dictionaries, which can be used as a Japanese input system for limited input devices such as mobile phones, PDAs and game appliances.
Conversion engine and learning efficiency are improved in Mobile Wnn V2. Input prediction is a unique technology of Omron. It enables users to minimize operation. Furthermore, 3 new learning functions are added to enhance efficient conversion of spoken language. Mobile Wnn V2 achieves a comfortable embedded Japanese input system, placing it far ahead of similar systems by other leading companies.
Intelligent conversion and less operation for comfortable input

Mobile Wnn V2 achieves 90% accuracy with its basic dictionary alone. (Source: Omron Software tests) A dictionary of new words and various optional dictionaries can be added to match user needs. Mobile Wnn V2 achieves highly efficient conversion for mobile phones.

An input prediction function is added for comfortable input with fewer keystrokes.

Input prediction
Mobile Wnn V2 memorizes words that users have input before. It predicts what character users will input next based on stored frequency data and converts the word before users finish inputting entire word. This function helps achieve fewer keystrokes.
